Answer:

The final answer is $x = -7$ .

Step-by-step explanation:

Solve the equation:

$5 + x = -2$

Subtract both sides by 5:

$5 - 5 + x = -2 -5$

$x = -7$

So, therefore, $x = -7$ is the final answer.

We need to get x by itself.

We do that by subtracting 5 from both sides.

This leaves us with x = -7.

So x = -7 is the solution.

The measure of the supplement of an angle is 60° less than four times the measure of the complement of the angle. Find the measu

LenaWriter [7]

Answer:

140° and 50°

Step-by-step explanation:

The supplement of the angle (180 - x)

The complement of the angle = (90 - x)

(180 -x) = 4(90-x) - 60

180 - x = 360 -4x - 60

180 -x = 300 - 4x

180 - x + 4x = 300

180 + 3x = 300

3x = 120

x = 40

The supplement (180 - x) = 180 - 40 = 140°

The complement (90 - x) = 90 - 40 = 50°

Mr. Rodriguez works in a store. He wants to arrange 12 toys in a display shaped like a rectangular prism. The toys are in cube-s

Vilka [71]

To find the different ways to display the boxes, you will find all the different ways you can make an array of 12.

12 x 1 and 1 x 12
2 x 6 and 6 x 2
3 x 4 and 4 x 3

There are 6 possibilities.

How do you solve the equation -7/8k=21

loris [4]

$- \frac{7}{8} k$ = 21

First, simplify $\frac{7}{8} k$ to $\frac{7k}{8}$ / Your problem should look like: $-\frac{7k}{8}$ = 21
Second, multiply both sides by 8. / Your problem should look like: -7k = 167
Third, divide both sides by -7. / Your problem should look like: k = $\frac{168}{-7}$
Fourth, simplify $\frac{168}{-7}$ to $\frac{168}{7}$ / Your problem should look like: k = $- \frac{168}{7}$
Fifth, simplify $\frac{168}{7}$ to 24. / Your problem should look like: k = -24

Answer: k = -24

The absolute value function is written f(x) = |x|. It is composed of the lines y = x and y = -x. Its domain is the real numbers

Katena32 [7]

1.
no, there will never be a negative y-value. y= |x| will always be nonnegative. |x| can be distance x is from 0 and a distance can never be negative.

2.
you can define it as
y = |x| = x if x ≥ 0, -x if x < 0

absolute value can be interpreted as a function that does not allow negative real numbers, forcing them to be positive (leaving 0 alone). if the input x is more than or equal 0, then x stays positive so there is no need to do anything: "x if x ≥ 0".
if the input is less than 0, then it is an negative number and needs a negative coefficient to negate the negative: "-x if x < 0"

example: if x = -3, then it will take the "-x if x < 0" piece resulting in y = -(-3) = 3, which is what |-3| does

if x = 1, it will take the "x if x ≥ 0" piece and just have y = 1 which is what |1| does.

for x = 0, it will take the "x if x ≥ 0" and just have y = 0 which is what |0| does
