Answer:
Given f(-2)
= -5 -7(-2)
= -5+14
= 9
Thus f(-2) of f(x)= 5-7x is 9
Answer:
Answer is D 5x-y>= 1 :)
Step-by-step explanation:
Multiply the bracket by 5
I used PEMDAS
P= parenthesis
E= exponents
M=multiplication
D= division
A= addition
S= subtraction
7r+2= 5(r-4)
7r+2= 5r-20
Move 5r to the left hand side . Positive 5r changes to negative 5r
7r-5r+2= 5r-5r-20
2r+2=- 20
2r+2-2= -20-2
Move positive 2 to the right hand side. Changes to negative -2
2r+2-2= -20-2
2r= -22
Divide by 2 for 2r and -22
2r/2= -22/2
r= -11
Answer is r= -11
Answer:
x <8
Step-by-step explanation:
-14x > -112
Divide each side by -14. Remember that flips the inequality
-14x/-14 < -112/-14
x <8
If the radius is tripped, the volume will increase by 3^3 = 27 times.
Answer: 27 times
