W. 3.6.41
given the following functions, find the indicated values.

f(x) = 5x² - x + 6
(a) f(0) (b) f( – 5) (c) f(5)
(a) f(0)

f(0) = 6, f(-5) = 136 , f(5) = 126

Step-by-step explanation: f(0) = 5(0)^ 2 - 0 + 6 = 6

f(-5) = 5(-5)^2 - (-5 )+ 6 = 125 +5 + 6 =136

f(5) = 5(5)^2 -5 + 6 =125 - 5 +6 =126

10

step-by-step explanation:

7+3=10

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
