Find the slope of the line passing through (3, 7) and (6, 11). Note: Use the y-y/x-x formula!

lana [24]

Answer:

Slope of the line $m = \frac{4}{3}$

Step-by-step explanation:

Explanation:-

Given points are ( 3,7) and (6,11)

Slope of the line

$m = \frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

$m = \frac{11-7}{6-3}$

$m = \frac{4}{3}$

Slope of the line $m = \frac{4}{3}$

The potential energy, P, in a spring is represented using the formula P = P equals StartFraction one-half EndFraction k x square

Anastaziya [24]

Answer:

$k=\frac{2P}{x^{2}}$

Step-by-step explanation:

The question is

Which equation should she use?

we have the formula

$P=\frac{1}{2}kx^{2}$

Solve for k

That means ----> isolate the variable k

Multiply by 2 both sides

$2P=kx^{2}$

Divide by x^2 both sides

$\frac{2P}{x^{2}}=k$

Rewrite

$k=\frac{2P}{x^{2}}$

Find two consecutive odd integers such that seven times the first equals five times the second.

fredd [130]

Answer:

Odd integers are always one more that an even integer:

1st: 2n+1

2nd: 2n+3

Step-by-step explanation:

14n+7 = 10n+15

4n = 8

n = 2

------------

1st: 2n+1 = 5

2nd: 2n+3 = 7

7x=5*(x+2)

7x=5x+10

7x-5x=10

2x=10

x=5
