Answer:

Yes

Step-by-step explanation:

-1x is a short notation for -1 * x. the "-" can stand for -1

So it would be (-1) * (1) * x

-x is also -1 * x

By the identity property of multiplication, a number x 1 remains the same number.

So it would be -1 * x, which is the same as -1 * x, so they're equal.

X = 4.

You have to distribute by multiplying -4 by the numbers between -3x and -2.

12x + 8 =60

Subtract the 8 from 60 to simplify the equation.

12x = 48

Divide 12 by 48 and get 4.

x=4

Andreyy89

Answer:

third graph and (3, -1)

Step-by-step explanation:

y = 2/3x - 3

y = -2x + 5

2/3x - 3 = -2x + 5

2 2/3x = 8

8/3x = 8

8x = 24

x = 3

find 'y'

y = -2(3) + 5

y = -1

The third graph is correct because it shows both a line intersecting the y-axis at -3 and the negative slope line is crossing at +5
