Bob is diving
he is at a depth of 2 meters below sea level
sam goes down 4 times as deep
how deep is sam
depth is a negative thing because you are 2 below 0 or -2
then we mutiply -2 by 4 to get 4 times to get -8 meters below sea level
The weather was -2 degrees outside and it got four times colder. What is the temperature now? (-8 degrees)

A.) 5/3
B.) 6
C.) undefined
D.) zero slope
Y = 30x
the b (y intercept) is 0
M = 30
B = 0
Mean = 26.75
Range = 25
The answer is C!
(gof)(3) = g(f(3))
so
f(3) = -2(3) + 8 = 2
g(f(3)) = 5(2) = 10
answer
C. 10
Answer:
x = 1 y = -4
Step-by-step explanation:
- Plug the value of y into the other equation.
x + 3y = -11
x + 3(-4x) = -11
x - 12x = -11
-11x = -11
x = 1
- Now substitute the value of x into any equation.
y = -4x
y = -4(1)
y = -4
