Answer:

x=10, 120

Step-by-step explanation:

5x+70=7x+50

-5x -5x

70=2x+50

-50 -50

20=2x

Graphing the function. h(x) = - 4 (show steps)

Archy [21]

Think about rise over run. Make the -4 a fraction into -4/1. Rise is the first, so you go down 4 pts down. Then run is 1, so you go 1 right. In this case, there is no beginning, so you begin at 0. The coordinates will be (0, 0) and (1, -4). You got the graph.

Carmen is a professor at a local university. In collecting data on her Introduction to Business course for a year, she wants to

AVprozaik [17]

Answer:

$\boxed {\boxed {\sf z=2.2}}$

Step-by-step explanation:

The z-score tells us how many standard deviations a value is away from the mean.

The formula is:

$z=\frac{x- \overline{x}}{s}$

where x is the value, $\overline {x}$ is the mean, and s is the standard deviation.

We want to find the z-score for the score of an 83, the mean is 72, and the standard deviation is 5.

$x=83 \\\overline {x}= 72 \\s=5$

Substitute the values into the formula.

$z=\frac{83-72}{5}$

Solve the numerator.

$z=\frac{11}{5}$

Divide.

$z=2.2$

The z-score is 2.2, which means the score of 83 is 2.2 standard deviations above the mean.

a diver is 19 meters below the surface of the water use an integer to represent how far the diver will need to travel to reach t

Basile [38]

Answer:

The diver need to travel 19 meter up to reach the surface

Step-by-step explanation:

* Lets explain how to solve the problem

- For any starting point the position at it is zero

- If the moving from the starting point is vertically, then the distance

below the starting point is negative and above the starting point

is positive

- If the moving from the starting point is horizontally, then the

distance left to the starting point is negative and right to the

starting point is positive

* Lets solve the problem

- A diver is 19 meters below the surface of the water

- Assume that the surface of the water is the zero position

∵ The diver is 19 meter below the surface of the water

∴ The diver is at the position -19

- The diver need to travel 19 meters to reach the surface of the water

∵ -19 + 19 = 0

∴ The diver need to travel 19 meter up to reach the surface
