Seven more times a number increased by seven is less than -11

Go slow and see what it's telling you. If n is our number, twice that is 2n. Increasing 2n by 7 gives us 2n + 7. That's not 9, because 2 is being multiplied by something unknown before we add 7. 2 + 7 = 9 and 2n + 7n = 9n, but 2n + 7 is just that.

Well, "is" is "=".

Three times the same number is 3n. Three less than that is 3n - 3, again not equal to 0.

2n + 7 = 3n - 3

Step-by-step explanation:

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
