Answer:

17 1/2

Step-by-step explanation:

The quickest way is to put it as it improper fraction and then multiply it like normal.

The Equation x² − 15x + 12 = 0 have two Real solution and 3x² − 6x + 4 = 0 have Imaginary solution.

The discriminant, denoted by the equation b² - 4ac, can be used to ascertain if the solutions are real, repetitive, or complex:

1) If the discriminant is smaller than 0, there are two imaginary roots to the problem (s).

2) The equation has one repeating real solution if the discriminant equals zero (s).

Given:

x² − 15x + 12 = 0

Solving the Quadratic Equation

x² − 15x + 12 = 0

D = b² - 4ac

D = (-15)² - 4(1)(12)

D =  225 - 48

D = 177 >0

So, the Equation will have two Real solution.

b) 3x² − 6x + 4 = 0

Solving the Quadratic Equation

3x² − 6x + 4 = 0

D = b² - 4ac

D = (-6)² - 4(3)(4)

D =  36 - 48

D =  -12 >0

So, the Equation will have Imaginary solution.

Answer:

y = 2/3 x + 7

Step-by-step explanation:

At birth represents the beginning of time for the baby. Lets call this month zero. So here are your coordinates.

x = 0 y = 7 ----> at birth

x = 3 y = 9

x = 6 y = 11

x = 9 y = 13

Now we find the slope between each point. Since the common difference of y is 2 and the common difference in x is 3 , the slope will be

slope = y / x = 2 / 3

Therefore, the equation of the line that represents this relationship is

y = (2/3) x + 7

a horizontal line always has a slope of 0, now, for the sake of a silly proof, let's do some rigamarole to get it.

to get the equation of any straight line, we simply need two points off of it, let's use those two in the picture below

\((\stackrel{x_1}{-3}~,~\stackrel{y_1}{7})\qquad (\stackrel{x_2}{7}~,~\stackrel{y_2}{7}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{\textit{\large rise}} {\stackrel{y_2}{7}-\stackrel{y1}{7}}}{\underset{\textit{\large run}} {\underset{x_2}{7}-\underset{x_1}{(-3)}}} \implies \cfrac{0}{7 +3} \implies \cfrac{ 0 }{ 10 } \implies \stackrel{ }{\text{\LARGE 0}}\)

The solution of the given equation 4(3x - 4) - 7( 2x + 3) = 3 is -20.

A linear equation is an equation that has the variable of the highest power of 1.

The standard form of a linear equation is of the form Ax + B = 0.

The given equation is;

4(3x - 4) - 7( 2x + 3) = 3

To solve;

4(3x - 4) - 7( 2x + 3) = 3

Solve the parentheses using the distributive property;

12x - 16 - 14x - 21 = 3

we need to get the like terms together;

12x - 14x -16 - 21 = 3

-2x - 37 = 3

Add 37 both sides, we get;

-2x = 40

Divide both sides by -2

x = -20

Hence, the solution of the given equation is -20.

Answer:

let me explain how you do this:

Step-by-step explanation:

first, you write your equation down:

-x + 5y = 8

next, group everything out seperately so you can know what to do in this problem, like grouping out each variable and number you see. then, figure out if the solution is simplified down to the last number. if so, if there is two variables that aren't the same, try and figure out a way to solve this equation with these two different variables. figure out if you have to multiply, subtract, add, or divide.

If the order of the elements matters, we will see that there are 6,972 different possible sets, if the order does not matter, we will see that there are 3,486 possible sets.

The possible elements of the set are positive integers less than 85, then the possible elements are: 1, 2, ..., 84

So we will have a set:

{n, m}

And we know that both n and m are numbers in the interval [1, 84] (we assume that n ≠ m and that order matters.}.

For the first element, we have a total of 84 options to choose.

For the second element, we have a total of 83 options (because we selected one already).

The total number of combinations is just given by the product between the numbers of options, so we have:

C = 84*83= 6,972

There are 6,972 different possible sets.

If order does not matter, then n and m permutations are irrelevant, then the number of combinations is given by C/2:

C/2 = 6,972/2 = 3,486

In this case, there are 3,486 possible sets.

The number 842 is the number whose digit 4 is ten times larger than in the number 384

To solve the problem, we need to find a number in which the digit 4 is ten times larger than in the number 384.

In the number 384, the digit 4 is in the ones place, which means that its value is 4.

To find a number in which the digit 4 is ten times larger, we need to find a number in which the digit 4 is in the tens place and its value is 10 times larger than 4, which is 40.

The only answer option that fits this description is 842. In this number, the digit 4 is in the tens place and its value is 40, which is ten times larger than its value in the number 384.

Therefore, the correct answer is 842.

Answer:

a) The basic rate of pay is 6 sterling pounds per hour.

b) The higher rate of pay is 10 sterling pounds per hour.

Step-by-step explanation:

Both segments of the curve are first order polynomials, which means that each have constant slopes.

a) The basic rate of pay is the value of the slope (\(r\)), in sterling pounds per hour, of the line for the first 20 hours worked, that is:

\(r = \frac{\Delta y}{\Delta x}\) (1)

Where:

\(\Delta x\) - Change in hours worked, in hours.

\(\Delta y\) - Change in pay, in sterling pounds.

If we know that \(\Delta x = 20\,h\) and \(\Delta y = \pounds\, 120\), then the basic rate is:

\(r = \frac{\Delta y}{\Delta x}\)

\(r = \frac{\pounds\,120}{20\,h}\)

\(r = 6\,\frac{\pounds}{h}\)

The basic rate of pay is 6 sterling pounds per hour.

b) By using (1), we calculate the higher rate of pay below. If we know that \(\Delta x = 10\,h\) and \(\Delta y = \pounds \,100\), then the higher rate is:

\(r = \frac{\Delta y}{\Delta x}\)

\(r = \frac{\pounds\,100}{10\,h}\)

\(r = 10\,\frac{\pounds}{h}\)

The higher rate of pay is 10 sterling pounds per hour.

The probability of the event between two and five lines, inclusive, are in use is 0.85.

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

Given that,

x         0         1         2       3        4         5         6

p(x)   0.12    0.18   0.20  0.20  0.20   0.07   0.03

a) At most three lines are in use

Here we need to find the probability for x≤3.

P(x≤3)=P(x=0)+P(x=1)+P(x=2)+P(x=3)

= 0.12+0.18+0.20+0.20

= 0.70

b) Fewer than three lines are in use

Here we need to find the probability for x<3.

P(x<3)=P(x=0)+P(x=1)+P(x=2)

= 0.12+0.18+0.20

= 0.50

c) At least three lines are in use

Here we need to find the probability for x≥3.

P(x≥3)=P(x=3)+P(x=4)+P(x=5)+P(x=6)

= 0.20+0.20+0.07+0.03

= 0.50

d) Between two and five lines, inclusive, are in use

Here we need to find the probability for 2≤x≤5.

P(2≤x≤5)= P(x=2)+P(x=3)+P(x=4)+P(x=5)

= 0.18+0.20+0.20+0.20+0.07

= 0.85

The healthy ice cream Jeremy is making has 30 bananas and requires 18 tablespoons of peanut butter.

The ratio describes the amount of quantity in simplest form, a:b can be written as 'a/b' for convenience.

Given the healthy ice cream, Jeremy is making requires 5 bananas and 3 tablespoons of peanut butter.

From the given question itself, we can conclude that bananas and peanut butter are in direct proportion as the increase in one quantity will result in an increase of another quantity and we can write this in proportion and let the no. of tablespoons of peanut butter requires for 30 banans is x.

∴ 5 : 3 : : 30 : x.

Or

5/3 = 30/x.

5x = 90.

x = 18.

So, Jeremy needs 18 tablespoons of peanut butter for the 30 bananas he has.

Answer:  Starting with 2(tan x - sqrt(3)) = 2:

First, divide both sides of the equation by 2 to simplify:

tan x - sqrt(3) = 1

Next, add sqrt(3) to both sides:

tan x = 1 + sqrt(3)

To solve for x, we need to take the arctan of both sides:
