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

Subtitute the pair (3,28) to x and y, if the result in right side is -8, then the pair is a solution to the equation

2x - y/2
= 2(3) - 28/2
= 6 - 14
= -8

The result is -8, so the pair (3,28) is a solution

Simplify (1-6)(-4-7)

lakkis [162]

Answer:

I’m guessing you subtract the numbers from the inside of the parenthesis and then multiply the two.

(-5)(-11) = 55

I hope this is correct.
