Answer:
x = 0
Step-by-step explanation:
Q(1, 2 ) and Q1(- 1, 2 ) are both 1 unit from the y- axis
Q is 1 unit to the right of the y- axis and Q1 is 1 unit is 1 unit to the left of the y-axis, thus
The y- axis is the mirror line with equation x = 0
The rate of change of any given function is simply taken to be the 1st derivate of that function.We are given:y = 5 x + 25So the rate of change is simply, rate of change = dy / dxdy = 5 dxdy / dx = 5
So rate of change = 5
I think it would be -2880
length = 32 and width = 5
let the width = w then length = 4w + 12
perimeter = 2 ( length + width )
= 2( 4w + 12 + w ) = 2( 5w + 12 ) = 10w + 24
perimeter = 74
solve 10w + 24 = 74
subtract 24 from both sides
10w = 74 - 24 = 50 ⇒ w = 5
width = 5 and length = (4 × 5) + 12 = 20 + 12 = 32
