Answer:

x = 1

Step-by-step explanation:

Given:

f(x) = -4x + 4
f(x) = 0

We are asked to solve for x when the function is equal to zero.

We should have: 0 = -4x + 4

Solve

1. Subtract 4 from both sides

0 - 4 = -4x + 4 - 4

-4 = -4x

2. Divide both sides by -4

-4 ÷ -4 = -4x ÷ 4

1 = x

Factor -3/4 out of 3/2x - 9/4y

Vikki [24]

Answer:

$-\frac{3}{4} \times (-2x +3y)$

Step-by-step explanation:

To factor out -3/4 out of that equation, multiply and divide by -3/4.

Say ;

= $\frac{3}{2}x -\frac{9}{4}y$

= $(\frac{3}{2}x -\frac{9}{4}y) \times \frac{-\frac{3}{4} }{-\frac{3}{4}}$

Now, rearranging and making necessary commutations.

= $-\frac{3}{4} \times (\frac{3}{2}x -\frac{9}{4}y) \times \frac{1 }{-\frac{3}{4}}$

= $-\frac{3}{4} \times (-2x +3y)$

Factoring -3/4 we get an equation without any fractions

= -2x + 3y
