Answer:
m = -5
Step-by-step explanation:
16−(7m+3)=8(1−m)
16 - 7m - 3 = 8 - 8m
16 - 3 - 8 = 7m - 8m
5 = -m
(-1) * 5 = -m * (-1)
-5 = m
therefore, m = -5

Can someone help me find the net prices for these? NEED THEM ASAP!!!
It should be noted that to find the net price of a product or service, you need to subtract any discounts or deductions from the gross price.
How to explain the net priceHere are the steps you can follow:
Determine the gross price: The gross price is the original price of the product or service before any discounts or deductions are applied.
Identify any discounts or deductions: Look for any discounts or deductions that apply to the gross price. These may include promotional discounts, coupons, or taxes.
Subtract the discounts or deductions: Subtract the total amount of discounts or deductions from the gross price. The result is the net price.
For example, let's say you want to buy a laptop that costs $1000. You have a 10% discount coupon, and there is a 5% sales tax. Here's how you can calculate the net price:
Gross price = $1000
Discount = 10% of $1000 = $100
Subtotal = $1000 - $100 = $900
Sales tax = 5% of $900 = $45
Net price = $900 + $45 = $945
So the net price of the laptop after applying the discount and sales tax is $945.

Lets say you have a bunch of pennies that you are dividing into different groups. How many pennies could you have when you break the pennies into groups of 2 , you have 1 penny left over
Answer: We have an odd number of pennies.
Step-by-step explanation:
So we have N pennies.
When we wan to divide the N pennies into groups of 2, we have a penny left over.
This means that N is not divisible by 2.
The problem is that there are infinite natural numbers that are not divisible by two, this is the set of odd numbers.
And remember that an odd number can be written as:
N = 2*k + 1.
where k is an integer.
Then we want to divide this by 2 (divide N into groups of 2)
we have:
N/2 = (2*k + 1)/2 = 2*k/2 + 1/2 = k + 1/2.
So we have k groups of 2 pennies, and a penny leftover that we can not divide into two.

1. 36^500=
2. 8 x 6^500 + 6^501
Answer:
1. z^2
2. 14z
Step-by-step explanation:
We know that (a^m)^n = a^(mn) = (a^n) ^mWe also know that (a^m)(a^n) = a^(m+n)
36 can be written as 6^2 and here 36^(500) can be written as (6^2)^500 which also can be written as (6^500)^2 and as already it is mentioned that 6^500 as z we can write the above as z^22. 8 x 6^500 = 8z
And we can also write 6^(501) as 6^(500+1) which is equivalent to 6(6^500) which is 6z.
From the above we can make sure that the question is the sum of the above which is 8z + 6z = 14z.

Line k is represented by the equation y = 2x + 2. Write
an equation of a line that is perpendicular to line k that also passes through the point (-2, 9)?
Step-by-step explanation:
so, we calculate the perpendicular slope, and then we start with the point-slope form (since we were given a specific point of the line), and transform into the regular slope-intercept form.
the slope in
y = 2x + 2
is the factor of x : 2 or 2/1
the perpendicular slope is turning this upside down and flips the sign : -1/2
the point- slope form is
y - y1 = a(x - x1)
"a" being the slope, (x1, y1) being the point.
y - 9 = -1/2(x - -2)
y - 9 = (-1/2)x - 1
y = (-1/2)x + 8

Answers to choose from:
A 22 5/6 square feet
B 120 1/6 square feet
C 120 1/3 square feet
D 129 1/6 square feet
Answer:
D. 129 1/6 square feet
Step-by-step explanation:
L x W = A is the equation used to solve for the area of quadrilaterals
When we substitute the values of L and W for what the length and width actually are, we end up with the equation 12 1/2 x 10 1/3 = A.
Now you just need to multiply the length and width which will give you 129 1/6 square feet.

what is the solution to the equation below? sqrt 2-3x / sqrt 4x =2
The solution to the equation sqrt 2-3x / sqrt 4x = 2 is x = -2/3.
To solve the equation, we must first clear the denominators and simplify the equation. We can do this by multiplying both sides by sqrt(4x) and then squaring both sides. This gives us:
sqrt 2-3x = 4sqrt x
2 - 6x + 9x² = 16x
9x² - 22x + 2 = 0
Using the quadratic formula, we can find that x = (-b ± sqrt(b² - 4ac)) / 2a. Plugging in a = 9, b = -22, and c = 2, we get:
x = (-(-22) ± sqrt((-22)² - 4(9)(2))) / 2(9)
x = (22 ± sqrt(352)) / 18
x = (22 ± 4sqrt22) / 18
Simplifying this expression, we get:
x = (11 ± 2sqrt22) / 9
Therefore, the solution to the equation is x = -2/3.
To solve the equation sqrt 2-3x / sqrt 4x = 2, we must clear the denominators and simplify the equation. This involves multiplying both sides by sqrt(4x) and then squaring both sides.
After simplifying, we end up with a quadratic equation. Using the quadratic formula, we can find that the solutions are x = (11 ± 2sqrt22) / 9.
However, we must check that these solutions do not result in a division by zero, as the original equation involves square roots. It turns out that the only valid solution is x = -2/3.
Therefore, this is the solution to the equation.

Which of the following lines is perpendicular to the line y=3/4x-2
Answer:
A. y = -⁴/3x + 4
Step-by-step explanation:
The line y = ¾x - 2 is given in the slope-intercept form, y = mx + b, where,
Slope (m) = ¾
y-intercept (b) = -2
Therefore, the equation of the line that is perpendicular to the line y = ¾x - 2 will have a slope (m) that is the negative reciprocal of ¾, which is -⁴/3.
Thus, the only equation that has a slope of -⁴/3 is y = -⁴/3x + 4.

shares of stock A at $90 per share and 75 shares of stock B at $145 per share. What is the
ween selling at the current day's high price or low price?
The difference in overall gain between selling stock A at the current day's high price or low price and selling stock B at the current day's high price or low price is $239.50.
To determine the difference in overall gain or loss between selling stock A at the current day's high price or low price and selling stock B at the current day's high price or low price, we need to calculate the selling prices of the stocks.
Stock A:
High price = $105.19
Low price = $103.25
Close price = $103.38
Stock B:
High price = $145.18
Low price = $143.28
Close price = $144.05
The investor purchased 50 shares of stock A at $90 per share and 75 shares of stock B at $145 per share.
To calculate the selling prices, we need to multiply the number of shares by the respective selling price.
Selling price of stock A at the high price: 50 shares \(\times\) $105.19 = $5,259.50
Selling price of stock A at the low price: 50 shares \(\times\) $103.25 = $5,162.50
Selling price of stock B at the high price: 75 shares \(\times\) $145.18 = $10,888.50
Selling price of stock B at the low price: 75 shares \(\times\) $143.28 = $10,746.00
Now, let's calculate the difference in overall gain or loss:
Difference in overall gain = Selling price at the high price - Selling price at the low price
= ($5,259.50 + $10,888.50) - ($5,162.50 + $10,746.00)
= $16,148.00 - $15,908.50
= $239.50

It is the graph of f(x) translated 11 units to the left.
It is the graph of f(x) translated 11 units up.
It is the graph of f(x) translated 11 units to the right.
B.
C.
OD.
The correct answer is C. It is the graph of f(x) translated 11 units to the left.
The correct answer is:
C. It is the graph of f(x) translated 11 units to the left.
When we have a function of the form g(x) = f(x - a), it represents a horizontal translation of the graph of f(x) by 'a' units to the right if 'a' is positive and to the left if 'a' is negative.
In this case, g(x) = f(x - 11), which means that the graph of f(x) is being translated 11 units to the right. However, the answer options do not include this specific transformation. The closest option is option C, which states that the graph of g(x) is translated 11 units to the left.
The graph of f(x) = x is a straight line passing through the origin with a slope of 1. If we apply the transformation g(x) = f(x - 11), it means that we are shifting the graph of f(x) 11 units to the right. This results in a new function g(x) that has the same shape and slope as f(x), but is shifted to the right by 11 units.
Therefore, the correct answer is C. It is the graph of f(x) translated 11 units to the left.

The slope-intercept style of an equations is used to represent a straight line only when equation is expressed as y = mx + b. The y-intercept is positioned where the slope of the line is m, b is b, and (0, b). For instance, the y-intercept and slope of the calculation y = 3x - 7 (0, 7).

The number a is less than the number b by (1)/(5) of b. By what part of a is b greater than a ?
Answer:
B is greater than A by 1/4 of A
Step-by-step explanation:
Let's use the information given in the problem to write expressions for the values of a and b:
a = b - (1/5)b = (4/5)b
b is greater than a by the difference:
b - a = b - (4/5)b = (1/5)b
To express this difference as a fraction of a, we divide by a:
(b - a)/a = ((1/5)b)/((4/5)b) = 1/4
Therefore, b is greater than a by 1/4 of a.
if m<xyz = 58 and m<wxz = 51 find m<wzx
Answer:
m<wzx = 71
Step-by-step explanation:
Assuming these are interior angles of a triangle.
The sum of all three interior angles of a triangle is always 180 degrees, therefore:
m<xyz + m<wxz + m<wzx = 180
Substitute our values:
58 + 51 + m<wzx = 180
m<wzx = 180 - 58 - 51

The total revenue for Dante's Villas is given as the function R(x)=700x−0.5x^2, where x is the number of villas rented. What number of villas rented produces the maximum revenue?
The revenue function is,
\(R(x)=700x-0.5x^2\)For maximum and minimum value, the first derivative of function is equal to 0.
Determine the first derivative of revenue function.
\(\begin{gathered} \frac{d}{dx}R(x)=\frac{d}{dx}(700x-0.5x^2) \\ R^{\prime}(x)=700-0.5\cdot2x \\ =700-x \end{gathered}\)For maximum and minimum value, R'(x) = 0. So
\(\begin{gathered} 0=700-x \\ 700=x \end{gathered}\)Since x = 700 corresponds to maximum or minimum value of revenue.
Determine the second derivative of revenue function.
\(\begin{gathered} \frac{d}{dx}R^{\prime}(x)=\frac{d}{dx}(700-x) \\ R^{\doubleprime}(x)=-1 \end{gathered}\)Since second derivative of revenue function is less than 0 for every value of x. So x = 700 corresponds to maximum value of revenue.
So 700 villas rented to produce maximum revenue.
Answer: 700 villas
