3 Find y if the slope between ( – 7, y) and (1, 13) is 3/4

mafiozo [28]

Step-by-step explanation:

$slope \: = \frac{y2 - y1}{x2 - x1} = \frac{3}{4}$

point 1 ( -7,y)

point 2 (1,13)

$\frac{13 - y1}{1 - ( - 7)} = \frac{3}{4}$

$\frac{13 - y1}{8} = \frac{3}{4}$

$13 - y2 = \frac{8 \times 3}{4} = 6$

$y2 = 13 - 6 = 7$

y = 7

2. Red light: Pedro drives the same route to work on Monday through Friday. His route includes one traffic light.

Nataly [62]

Answer:

So, the probability is P=0.018.

Step-by-step explanation:

We know that Pedro drives the same route to work on Monday through Friday.

We know that there is a 55% chance that the light will be red.

We get that p=55%=0.55.

We conclude that the probability of not being a red light:

q=1-p=1-0.55=0.45.

We can calculate the probability that from Monday to Friday when Pedro goes to work there will be no red light, as follows:

$P=q^5\\\\P=0.45^5\\\\P=0.018$

So, the probability is P=0.018.

PLEASE NO LINKS, I will report you.

FromTheMoon [43]

Answer:

for 18 x is 6 and for 20 it is 11

Step-by-step explanation:

For 18, since -1+2x and 5+x is the same thing, set up and equation. WE can simplify to -1+x=5 and then we get x=6

For 20, 18 is 11 since 18=-4+2x. If we simplify we get 22=2x then we can use algebra to say that x=11

Hope this helps :)
