In this question we already know the value of 'b' so put the value b=2 in the equation

=|4(2)-8| + |-1-(2)^2| + 2(2)^3

=|8-8| + |-1-4| + 2(8)

=0 -5 +16

=11

Solve for x (get x by itself)

$4x-\frac{5}{y} =2z$ Add 5/y on both sides

$4x-\frac{5}{y}+\frac{5}{y}=2z+\frac{5}{y}$

$4x=2z+\frac{5}{y}$ Divide 4 on both sides to get "x" by itself

$\frac{4x}{4} =\frac{2z+\frac{5}{y}}{4}$

$x = \frac{z}{2}+\frac{5}{4y}$

If dividing 4 confuses you, then you can do this:

$4x=2z+\frac{5}{y}$ Multiply 1/4 on both sides

$(\frac{1}{4})4x=(2z+\frac{5}{y})(\frac{1}{4})$ Distribute 1/4 into (2z + 5/y)

$x=(2z(\frac{1}{4})+\frac{5}{y}(\frac{1}{4}))$

$x = \frac{z}{2} +\frac{5}{4y}$

Answer:

k = 9

Step-by-step explanation:

<u>Using slope formula to find the value of k:</u>

(-9 - k)/(-2 - (-4)) = - 9
(-9 - k)/2 = - 9
- 9 - k = - 18
k = 18 - 9
k = 9
