Please help!(30pts)(I NEED IT QUICK)Find the inverse of the given function:
bezimeni [28]

y = -(1/2) sqrt(x + 3) Interchange the x and y

x = -(1/2) sqrt(y + 3) multiply through by - 2

-2x = sqrt(y + 3) Square both sides.

(-2x)^2 = (sqrt(y + 3))^2

4x^2 = y + 3 Subtract 3 from both sides.

y = 4x^2 - 3

The usual rule is to interchange the domain and range of the original equation with the inverse. The range of the original equation is 0 => y > -infinity.

If that is the case, then the domain of the inverse is 0<=x. The graph was revised and provided by Mathmate. It is the correct way to represent this function and it's inverse Including the fact that x<=0. That restriction is very important. The line is x = y and the graphs should reflect around that line.

Answer:

Yeah, you can prove with the use of alternate interior angles, alternate exterior angles, and parallel angles. That's why they're similar.

<h3>What are linear equations?</h3>

Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

<h3>How to determine the graph of the points on the coordinate plane.?</h3>

A system of linear equations is a collection of at least two linear equations.

In this case, the points are given as

(7, 3) and (1, 5)

The point (7, 3) means that:

x = 7 and y = 3

i.e. the point is located 7 units to the right of the origin and 3 units up the origin

Similarly,

The point (1, 5) means that:

x = 1 and y = 5

i.e. the point is located 1 unit to the right of the origin and % units up the origin

Next, we plot the points on the coordinate plane.

See attachment of the graph of the points on the coordinate plane.

Two squares are similar. The
Pepsi [2]

Answer:

The perimeter of the second square is 36 inches

Step-by-step explanation:

Given

Represent the sides of the squares with S1 and S2.

So:

S_1:S_2 = 1 : 3 --- Scale factor

P_1 =12 --- perimeter of the first

Required

Calculate P2, the perimeter of the second

Represent the ratios of the perimeter:

Scale = P_1 : P_2

Substitute 12 for P1

Scale = 12 : P_2

Equate both scale factors

12 : P_2 = 1:3

Convert to fraction

\frac{12}{P_2} = \frac{1}{3}

Cross multiply

P_2 = 12 * 3

P_2 = 36
