Please help –8 = c /9 c=
kramer

Hey there! I'm happy to help!

We want to get c all by itself on one side of the equation. Usually variables go on the left side, so let's flip the equation around.

c/9=-8

If we multiply c/9 by 9, the 9 will cancel out because if you divide by 9 and then multiply by 9 it just equals 1. We can do this to isolate the c, but whatever you do to one side of the equation, you have to do to the other. So, we multiply both sides by 9.

c/9×9=-8×9

c=-72

Have a wonderful day! :D

Question 1
fredd [130]

Hello!

The graphs of sine and cosine are waves. Therefore, choice A and B are wrong.

The graph of f(x) = cot(x) is an inverse of f(x) = tan(x), so therefore the graph of f(x) = cot(x) has the lines similar to the graph above, but it's flipped.

So therefore, the graph shown above is choice C, f(x) = tan x.

Mrs. White paid $946.50 for five plane tickets. How much did each plane ticket cost?
lakkis [162]

Answer:

Each plane ticket was $189.3

Step-by-step explanation:

If all tickets were at the same price, and for five tickets the person paid $946.50, then to find out how much was each ticket, we simply have to divide this quantity by 5:

$946.5 / 5 = $189.3
