Please answer all for brainlest and thanks !!! I'm begging :((

You can find a unit rate when given a rate by dividing the the second number in the rate (if you had 3:4, you would divide 4) by the same number. (in the problem I gave you, you would divide 4 by 4 to get 1 then divide 3 by 4.) Then you would have the unit rate. Sorry if that didn't make any sense.

Find f(-10) f(x)=7x-5​
Inessa [10]

Answer:

<h2>f(-10) = -75</h2>

Step-by-step explanation:

F(x) is simply another way of saying y. We are given the x value of -10. We can substitute this in for x and find y.

f(-10) = 7(-10) - 5

f(-10) = -70 - 5

f(-10) = -75
