Answer:
Number 7: 
This graph displays the change in wage per years of service. Since the slope is positive, this means the wage has a positive growth.
Number 8: 
This graph displays the amount of people evacuating per hour. Since the slope is negative, this means the amount of people evacuating per hour is reducing.

Answer:
The answer x=13 or x=1
Step-by-step explanation:
Let's solve your equation step-by-step.
|x−7|=6
Solve Absolute Value.
|x−7|=6
We know eitherx−7=6orx−7=−6
x−7=6(Possibility 1)
x−7+7=6+7(Add 7 to both sides)
x=13
x−7=−6(Possibility 2)
x−7+7=−6+7(Add 7 to both sides)
x=1
Answer:
x=13 or x=1
Answer:
(1.82, 3.17)
Step-by-step explanation:
Given the curve:
y = cosh(x)
we need that the tangent has slope 3. The tangent of a curve in a given point is found with its derivative.
dy/dx = sinh(x) = 3
From the plot of sinh(x), we get:
x ≈ 1.82
Replacing into cosh(x), we get:
y = cosh(1.82) ≈ 3.17
Then, at point (1.82, 3.17) the tangent is 3
