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!

If f(x) = 3x + 5 and g(x) = x - 1, then g[f(-3)] = ?
Dominik [7]

Answer:

-3fg

Step-by-step explanation:

I can't tell exactly what you're trying to say but if you're trying to say:

g x (f x (-3)), then here's how you do it:

g x (f x (-3))

Multiplying a positive and a negative equals a negative: (+) x (-) = (-), then use the commutative property to reorder the terms.

g x (-f x 3)

g x (-3f)

Multiplying a positive and a negative equals a negative: (+) x (-) = (-), the use the commutative property to reorder the terms.

-g x 3f

-3fg
