If f (x) = 4x - 7 and G(x) = 2x + 4 , evaluate f(x) + g(x) for x = -3

avanturin [10]

Hi there!

• x = - 3

Let's first calculate f(x) and g(x) individually :-

• f(x) = 4x - 7

⇒ 4(- 3) - 7

⇒ - 12 - 7 = - 19

$\boxed{\text{f(x)} = - 19}$

• g(x) = 2x + 4

⇒ 2(- 3) + 4

⇒ - 6 + 4 = - 2

$\boxed{\text{g(x)} = - 2}$

According to th' question :-

f(x) + g(x)

⇒ - 19 + (- 2)

⇒ - 19 - 2

⇒ - 21

$\boxed{\text{f(x) + g(x)} = - 21}$

~ Hope it helps!

Find f(-5) if f(n) = n^3 + 3n^2

Andrew [12]

Plug in -5 for n
-5^3 + 3(-5)^2
-125 + 3(25) = -125 + 75 = -50
f(-5) = -50

What is the measure of the complement?

Veronika [31]

Answer:

64°

Step-by-step explanation:

If two angles add up to give 90°, that are said to be complementary. One is a complement of the other.

Therefore, given that the measure of an angle, angle A = 26°, the measure of the complement of angle A = 90 - 26 = 64°.

The measure of the complement of angle A, is 64°.
