Answer:

No its not

Step-by-step explanation:

When 42(x + 14y) is simplified:

42(x + 14y)

Expand and remove the brackets. Remember brackets mean to multiply.

42*x

42x

42*14y

588y

42x+588y

Therefore 42x-56 is NOT EQUIVALENT to 42(x + 14y) but is equivalent to 42+588y

Answer:

Y = 40

Step-by-step explanation:

First, find the slope-intercept of the table

Slope-intercept form: y = mx + b

$m=\frac{y_2-y_1}{x_2-x_1}$

(3, 1) and (6,2)

$m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{2-1}{6-3}\\\\m=\frac{1}{3}$

$y=mx+b$

$y=\frac{1}{3}x+b$

Find b using (6,2):

$y=\frac{1}{3}x+b\\\\2=\frac{1}{3}(6)+b\\\\2=\frac{6}{3}+b\\\\2=2+b\\\\-2\ -2\\\\0=b$

$y=\frac{1}{3}x+b== > y=\frac{1}{3}x+0== > y=\frac{1}{3}x$

$y=\frac{1}{3}x$

What will be the value of Y when X = 120?

Substitute 120 for x into $y=\frac{1}{3}x$

$y=\frac{1}{3}x\\\\y=\frac{1}{3}(120)\\\\y=\frac{120}{3}\\\\y=40$

(120, 40)

Therefore, when X = 120, Y = 40

Hope this helps!
