Rectangle S = 2L · 2W = 2(L · W)

10.  A. (1, 3)

  • y = x + 2
  • y = -2x + 5

x + 2 = -2x + 5

Answer:

50

Step-by-step explanation:

180-(x+80) + 180-(2x+20) = 180 -70

180-x-80 + 180-2x-20 = 110

100-x + 160-2x = 110

260 - 3x = 110

-3x = -150

x = <u>50</u>

Let f(x) = -3x + 2 and g(x) - 4x + 6. Find (f•g)(-5).
mezya [45]

Answer:

(f•g)(-5) = -238

Step-by-step explanation:

We have that:

f(x) = -3x + 2

g(x) = 4x + 6

Find (f•g)(-5).

First we find (f.g)(x)

So

f(x)*g(x) = (-3x + 2)*(4x + 6) = -12x² -10x + 12

When x = -5

-12(-5)² - 10(-5) + 12 = -238

(f•g)(-5) = -238
