At x=-2, f(x)=-1. at x=4, f(x)=-13.
Answer:
see below
Step-by-step explanation:
10x+18<-2
Subtract 18 from each side
10x+18-18<-2-18
10x < -20
Divide by 10
10x/10 < -20/10
x < -2
Answer:
Below
Step-by-step explanation:
You can use Pythagorean theorem to find the hypotenuse of a right triangle.
a2 + b2 = c2
The square root of 15 = 3.8729.... (a bunch of other numbers)
4^2 + 3.8729^2 = c2
16 + 15 = 31
Now that you have this, you need to find the square root
The square root of 31 = 5.56775436
Rounding this to the tenth it would be: 5.57
Final answer: C = 5.57
hope this helps! :)
Answer:
p - 7 = 42
Step-by-step explanation:
"Less than" might make you think of the < sign, but that's a mistake. The expression 7 < p = 42 makes no sense! In fact, that would say, "7 <u>is</u> less than p and p = 42."
To find 7 less than a number, you subtract 7 from the number. You start with the number, then subtract 7.
p - 7 = 42
