Answer:
Let's solve your equation step-by-step.
|−x−15|=|5x−23|
Solve Absolute Value.
|−x−15|=|5x−23|
We know either−x−15=5x−23or−x−15=−(5x−23)
−x−15=5x−23(Possibility 1)
−x−15−5x=5x−23−5x(Subtract 5x from both sides)
−6x−15=−23
−6x−15+15=−23+15(Add 15 to both sides)
−6x=−8

−6
(Divide both sides by -6)
x=

−x−15=−(5x−23)(Possibility 2)
−x−15=−5x+23(Simplify both sides of the equation)
−x−15+5x=−5x+23+5x(Add 5x to both sides)
4x−15=23
4x−15+15=23+15(Add 15 to both sides)
4x=38

Step-by-step explanation:
If the measure of angle A = 40 and B is a complement of A, then the measure of angle B = 50. If C is a supplement of B, then the measure of angle C = 130.
the measure of angle A = 40
the measure of angle B = 50
the measure of angle C = 130
Hope this helps!
So " the line of best fit " would be 5(h) to 200(m) .
Which would also be 5:200 .
So after you can divide, so 5/5 would be 1 and 200/5 would be 40.
So it would be 1 to 40 (1:40).
The equation would be 40x.

Answer:
We conclude that speed is greater than 30 miles per hour.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 30 miles per hour
Sample mean, 
= 35 miles per hour
Sample size, n = 15
Alpha, α = 0.01
Sample standard deviation, s = 4.7 miles per hour
First, we design the null and the alternate hypothesis
We use one-tailed(right) t test to perform this hypothesis.
Formula:
Putting all the values, we have
Now, 
Since,
We fail to accept the null hypothesis and reject it. We accept the alternate hypothesis and conclude that speed is greater than 30 miles per hour.
We calculate the p-value.
P-value = 0.00052
Since p value is lower than the significance level, we reject the null hypothesis and accept the alternate hypothesis. We conclude that speed is greater than 30 miles per hour.
