Answer:

y=4x-7

Step-by-step explanation:

Add 12x to both sides to get 3y=12x-9

Divide by 3 to get y=4x-3

If the line is parallel, the slope is still 4x. So it is y=4x+n.

If in the coordinate point, x=2, and y=1, then the equation is now:

1=(4*2)+n, or 1=8+n

Subtract 8 from both sides to get n=-7

So, the equation is y=4x-7

The converse of the conditional statement "If a polygon has three sides, then it is a triangle" is:

D. If a polygon is a triangle, then it has three sides.

In the original conditional statement, the "if" part is "a polygon has three sides," and the "then" part is "it is a triangle." The converse switches the positions of the "if" and "then" parts, resulting in the statement "If a polygon is a triangle, then it has three sides."

g(\((\sqrt{x+1}^2+3)/(\sqrt{x+1} )\)

rewrite \(\sqrt{x+1}^2\) as x +1

g \((\sqrt{x+1}^2)\) = \(\frac{x+1+3}{\sqrt{x+1} }\)

add 1+3

g\((\sqrt{x+1}^2)\)=\(\frac{x+4}{\sqrt{x+1} }\)

combine and symplify

\(g{\sqrt{x+1} } *\frac{{x+4 (\sqrt{x+1}) } }{{x+1} }\)

reorder factors of the second side

\(g{\sqrt{x+1} } *\frac{{\sqrt{x+1} (x+4) } }{{x+1} }\)

take out the root x+1

and you are left with A

f(g(x))

substitue g into f

f(\(f{\sqrt{x+3} } =\((\sqrt{x+3})^2 +9}\)

rewrite sqrroot x+3 as x+3

\(f{\sqrt{x+3} } =\(x+3 +9}\)

Now add 3+9

\(f{\sqrt{x+3} } =\(x+12}\)

we get x+12

Now for domain

\(f{\sqrt{x+3} } =\((\sqrt{x+3})^2 +9}\)

set the radicand root sqr x+3 >= 0 to find the expression defined

\(x+3\geq 0\)

subtract 3 from both sides

\(x\geq 3\)

Answer:

The table represents a nonlinear function because the rate is not constant.

Step-by-step explanation:

As shown in the picture below, the x side of the table has the same rate of change of +1. However, due to the fact that the y side does not have the same rate of change, +6 and +3, the table represents a non linear function. If the rate on the y side of the table were all the same, then this would be a Linear function.

The area and perimeter of the parallelogram are: 56 square units and 30 units respectively

In Euclidean geometry, a parallelogram is a simple (non-self-intersecting) quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure

The parameters that will help us do the math are

base = 7

height = 8

Area = 8*7 = 56 square units

perimeter 2b + 2h

perimeter = 2*7 + 2*8

= 14 +16

P = 30 units

Therefore, the perimeter of the parallelogram and area are 30 units and 56 square units

Answer:

The insect population after 6 days is of 1639 insects.

Step-by-step explanation:

A population of insects increases at a rate 230 + 8t + 0.9t2 insects per day

This means that \(r(t) = 230 + 8t + 0.9t^2\)

The population of insects after x days is given by:

\(P(t) = \int_{0}^{x}r(t)dt\)

So

\(P(x) = \int_{0}^{x} (230 + 8t + 0.9t^2)\)

\(P(x) = 230t + 4t^2 + 0.3t^3 + K|_{0}^{x}\)

\(P(x) = 230x + 4x^2 + 0.3x^3 + K\)

In which K is the initital population(which is 50). So

\(P(x) = 230x + 4x^2 + 0.3x^3 + 50\)

After 6 days:

\(P(6) = 230*6 + 4*6^2 + 0.3*6^3 + 50 = 1638.8\)

Rounding to the nearest insect, 1639

The insect population after 6 days is of 1639 insects.

Step-by-step explanation:

The original price of the bracelet was £1400.

Percentage is a way of expressing a proportion or a fraction as a part of 100. It is denoted using the symbol "%". For example, 50% means 50 out of 100, or half, while 25% means 25 out of 100, or one-quarter.

We can start by using the information given to set up an equation that relates the original price of the bracelet with the sale price and the percentage reduction:

original price x (100% - 70%) = sale price

Simplifying the percentage reduction:

original price x 30% = sale price

Substituting the given sale price (£420):

original price x 30% = £420

To solve for the original price, we need to isolate it on one side of the equation. We can do this by dividing both sides by 30% (which is the same as multiplying by 100/30 or 10/3):

original price = sale price / 30% = £420 / 30% = £1400

Therefore, the original price of the bracelet was £1400.

Complete question - A jewelry shop is having a sale. A bracelet is now reduced to £420. This is 70% of the original price. Work out the original price of the bracelet.

m<5= 75° Alternate angles are equal

m<6 = 180°-75°= 105 ° Angles on a straight line adds up to 180°

In a rectangle opposite sides are equal so AB= CD

2x+8= 3x+4

3x-2x=8-4 ( combine like terms, the signs will change since they are going over opposite sides)

x= 4

To solve for BC

AD= BC

x+17 ( we know that x=4)

4+17=21

Therefore BC= 21

the value for the expression x² - x + y² for x = 5 and y = - 2 will be 24.

We are given an expression:

x² - x + y²

We need to find the value of the expression for x = 5 and y = - 2.

Now, substituting the values of x and y in the expression that is given to us, we get that:

x² - x + y²

( 5 )² - ( 5 ) + ( - 2 )²

Solving the squares of the numbers, we get that:

25 - 5 + 4

Simplifying to get the value of the expression, we get that:

= 24

Therefore, the value for the expression x² - x + y² for x = 5 and y = - 2 will be 24.

The polynomial with the given zeros is:;

P(x) = (300/108)*x*(x + 1)*(x - 1)*(x - 3/2)

Remember that if a polynomial has the zeros a, b, c, and d, then we can write it as:

P(x) = K*(x - a)*(x - b)*(x - c)*(x - d)

Where K is a coefficient.

Here the zeros are 0, -1, 1, 3/2

Then we can write:

P(x) =K*(x - 0)*(x + 1)*(x - 1)*(x - 3/2)

P(x) =K*x*(x + 1)*(x - 1)*(x - 3/2)

We also know that when x = -3, P(x) = 300

Then we can write:

300 = K*(-3)*(-3 + 1)*(-3 - 1)*(-3 - 3/2)

300 = K*(-3)*(-2)*(-4)*(-9/2)

300 = K*108

300/108 = K

Then the polynomial is:

P(x) = (300/108)*x*(x + 1)*(x - 1)*(x - 3/2)

Let’s solve the equation x^2 - 4x = 5 by factoring:

First, we’ll move all the terms to one side of the equation:

x^2 - 4x - 5 = 0

Now, we’ll factor the left side of the equation. We’re looking for two numbers that multiply to -5 and add to -4. Those numbers are -5 and 1. So we can write:

(x - 5) (x + 1) = 0

Now we’ll use the zero-product property to solve for x. This property states that if the product of two numbers is zero, then at least one of the numbers must be zero. So we have:

x - 5 = 0 or x + 1 = 0

Solving each equation separately, we find that x = 5 or x = -1.

So, the solutions to the equation x^2 - 4x = 5 are x = 5 and x = -1.
