Line s passes through points (7, 10) and (2, 14). Line t is parallel to line s. What is the slope of line t?

notsponge [240]

Answer:

The slope of line t is -4/5.

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(14-10)/(2-7)

m=4/-5

Parallel lines have same slopes.

I need help with my geometry homework! Thank you! I will mark brainliest!!!!

Firlakuza [10]

Answer:

The first choice is the one you want

Step-by-step explanation:

Use geometric means to solve for a first. The formula is

$8^2=15a$ and 64 = 15a and a = 64/15

That one was quite easy. Finding b is a bit more difficult.

The formula for finding b is

$\frac{a}{b}=\frac{b}{15+a}$

Solving for b:

$b^2=a(15+a)$

Filling in we have

$b^2=15(\frac{64}{15})+(\frac{64}{15})^2$ and

$b^2=64+\frac{4096}{225}$ and

$b^2=\frac{18496}{225}$ so b = 136/15

assume that 70% of teenagers who go to take the written drivers license test have studied for the test. Of those who study for t

wel

$P = \frac{P(pass AND not study)}{P(pass AND study) + P(pass AND not study)} \\ \\ P = \frac{(.6)(.3)}{(.95)(.7) + (.6)(.3)} \\ \\ P = 0.213$
