5p-9=2p+12
5p-2p=12+9
3p=21
p=21/3
p=7

P=3
+9 on both sides cancels the 9 and makes it 7p=21
7 divided by 21 is 3
p=3

Answer:

2x+10 = 2(x+5)

5x-15 = 5(x-3)

8x+6 = 2(4x+3)

Passes through the points (−4, 2) and (12, 6)?

svlad2 [7]

I'll assume you need to find the equation of the line that passes through those points.

Answer:

$\displaystyle y-2=\frac{1}{4}(x+4)$

Step-by-step explanation:

Equation of a Line:

The equation of a line passing through points (x1,y1) and (x2,y2) can be found as follows:

$\displaystyle y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

The given points are (-4,2) and (12,6), thus:

$\displaystyle y-2=\frac{6-2}{12+4}(x+4)$

Operating:

$\displaystyle y-2=\frac{4}{16}(x+4)$

Simplifying, the equation in point-slope form is:

$\mathbf{\displaystyle y-2=\frac{1}{4}(x+4)}$

Do these two have the correct answers?

Lapatulllka [165]

Yes, both of your answers are correct.

Since Death Valley is below sea level, the hiker increases altitude before stopping at 0 feet.

Percent of increase is given by the formula (amount of change)/(original amount) * 100. Your work is accurate.
