Answer:

ABC = 87°

Step-by-step explanation:

So ABC is x + 32 because the angles are vertical. ABC is also supplementary to ABD so you can make an equation.

3x + 15 = 180

3x = 165

x = 55

ABC = 55 + 32 = 87

P(x) = x^4 – 2x^3+ kx – 4 where k is an unknown integer.

mestny [16]

Answer:

k = 4

Step-by-step explanation:

Given,

$P(x)=x^{4} -2x^{3} +kx-4$

when , P(x) is divided by (x - 1) , the remainder = 0

⇒ $P(x) = (x-1)(x^{3} -x^{2} -x+4)$

hence, k = 4

Y=5+3x for x <br> Show work

Levart [38]

Answer:

$x = \frac{y - 5}{3}$

Step-by-step explanation:

Hello!

To solve for x, we have to first isolate the variable.

<h3>Solve for x</h3>

$y = 5 + 3x$
$y - 5 = 3x$
$y - 5 = 3(x)$
$\frac{y - 5}{3} = x$

The value of x is $\frac{y - 5}{3}$ .
