First you distribute:
4y - (2 * \frac{3}{2}y) - (2 * 5)
4y - 3y - 10

Then you combine like terms:
(4y + -3y) - 10
1y - 10

Simplify:
y-10

<u>Part 1</u>

<u />f(a)=4-7a+16a^2

<u>Part 2</u>

<u />f(a+h)=4-7(a+h)+16(a+h)^2\\\\=4-7(a+h)+16(a^2 +2ah+h^2)\\\\=4-7a-7h+16a^2 +32ah+16h^2

<u>Part 3</u>

<u />\frac{f(a+h)-f(a)}{h}=\frac{(4-7a-7h+16a^2 +32ah+16h^2-(4-7a+16a^2)}{h}\\\\=\frac{-7h+32ah+16h^2}{h}\\\\=32a+16h-7

The eqution of the diagonal of a parallelogram is 3y=5x +k. The two opposite vertices of a parallelogram are the points (1,-2),
astraxan [27]

Answer:

k = 1

Step-by-step explanation:

Given

3y = 5x + k

Opposite points: (1,-2) and (-2,1)

Required

Find k

First, calculate the midpoint of the opposite points.

(x,y) = 0.5(x_1 + x_2,y_1 + y_2)

This gives:

(x,y) = 0.5(1 -2,-2 + 1)

(x,y) = 0.5(-1,-1)

Open bracket

(x,y) = (-0.5,-0.5)

The equation 3y = 5x + k becomes:

3 * -0.5 = 5 * -0.5 + k

-1.5 = -2.5 + k

Solve for k

k = 2.5-1.5

k = 1
