The parabola y=x^2 is reflected across the x axis and then scaled vertically by a factor of 1/8.

tekilochka [14]

ANSWER

The new equation is:

$y = - \frac{1}{8} {x}^{2}$

EXPLANATION

The given parabola has equation,

$y = {x}^{2}$

This is the parent function.

When we reflect this parabola in the x-axis and then scaled vertically by a factor of 1/8.

The new equation becomes:

$y = - \frac{1}{8} {x}^{2}$

Two step Equation a.3x-8=31

stira [4]

<span>Simplifying 3x + -8 = 31 Reorder the terms: -8 + 3x = 31 Solving -8 + 3x = 31 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '8' to each side of the equation. -8 + 8 + 3x = 31 + 8 Combine like terms: -8 + 8 = 0 0 + 3x = 31 + 8 3x = 31 + 8 Combine like terms: 31 + 8 = 39 3x = 39 Divide each side by '3'. x = 13 Simplifying x = 13</span>

HELP ME A.S.A.P. PLZZZZ

Ronch [10]

Answer:

A = 66.5 in²

Step-by-step explanation:

There are a few different equations to find the area of a rhombus. If you are given the measurements of the two diagonals, you can use the following formula:

Area (A) = $\frac{d_{1}d_{2} }{2}$

Using this formula, you can multiply the measures of the diagonals and then divide by 2:

area = $\frac{(9.5)(14)}{2} =\frac{133}{2}=66.5in^{2}$
