The solution of equations system using the Substitution Method y = 3x & 2y+2x=24 is (3,9)
true
or
false
help mee​

True

Step-by-step explanation:

Plugging y = 3x in the equation 2y + 2x = 24, we find:

2(3x) + 2x = 24

6x + 2x = 24

8x = 24

x= 24/8

x = 3

Plugging x = 3 in the equation y = 3x we have:

y = 3*3 = 9

(x, y) = (3, 9)

answer: 21$

step-by-step explanation:

$42 / $14 = 3   (ratio 3: 1)

$7 x 3 = $21

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
