Given f(x) = 4x4 + 5x3 – 15x2 – 45, find f(–3).

poizon [28]

Answer:

f(–3) = 9

Step-by-step explanation:

Given f(x) = 4x^4 + 5x^3 – 15x^2 – 45

f(-3) means let x = -3

f(-3) = 4(-3)^4 +5(-3)^3 – 15(-3)^2 – 45

=4(81) +5(-27) -15(9) -45

= 324 - 135 - 135 -45

The angle Johnny holds his pen on paper creates a linear pair. The measure of one angle is 13x+7. The measure of the second angl

lisov135 [29]

we know that

Angles in a linear pair are supplementary angles

Let

A-------> the first angle

B------> the second angle

$A+B=180\\$ ----> equation $1$

$A=13x+7\\ B=2A-1=B=26x+13$

Substitute the values of A and B in the equation $1$

$13x+7+26x+13=180\\ 39x=180-20\\ x=\frac{160}{39}$

$\frac{160}{39}=4.10\ degrees$

therefore

the answer is

the value of x is $4.10\ degrees$
