Answer:

Hope i helped but i am not sure chief if that is what you needed

Step-by-step explanation:

you said in the comment we need to find the gallons so if we have the cost  10$ per 2 gallons then 20$ per 4 gallons. Then technicly 1 gallon will be 0 $

But if we need to find the value of the red dots it's starting from the top

40$ for the value of 8

30$ for the value for 6

20 $ for the value of 4

10$ for the value of 2

You can conclude that the cost bar increases by 2 each time

What are the missing angle measures in triangle ABC?
Finger [1]

we know that

In the right triangle ABC

∠A+∠B=90 ------> by complementary angles

so

Step 1

Find the measure of angle B

we know that

tan\  B=\frac{opposite\  side\  angle\  B}{adjacent\  side\  angle\  B}

in this problem

opposite\  side\  angle\  B=7in\\ adjacent\  side\  angle\  B=5in

so

tan\  B=\frac{7}{5} \\ \\ B=arc\ tan\frac{7}{5} \\ \\ B=54.5\ degrees

Step 2

Find the measure of angle A

A+B=90\\ A=90-B\\ A=90-54.5\\ A=35.5\ degrees

therefore

the answer is the option

35.5° and 54.5°

Step-by-step explanation:

y = x - 4 and y = 4x + 2

=> x - 4 = 4x + 2

=> 3x = -6

=> x = -2

y = x - 4 = (-2) - 4 = -6

The solutions are x = -2 and y = -6.
