Step-by-step explanation:
This will result to 3k+4=22 because minus times minus is plus
Therefore, 3k=22-4, when +4 crosses over the equals to sign it becomes -4
=> 3k=18
=> Divide both sides by 3 to get k
=> k=6
Answer:
reflected over the x-axis, compressed horizontally by a factor of 1/2.
Step-by-step explanation:
y(x) and f(x) means the same.
y = -(2x) means that y(x) was multiplied by -1, and x was replaced by 2x
- -y(x) reflects y(x) across x-axis
- y(a*x) compresses horizontally y(x) by a factor of 1/a. Here, a is 2, then the factor is 1/2.
Answer:
perimeter = 43.96 m
area = 153,86 m2
Step-by-step explanation:
d = 14 m
r = 7 m
perimeter = 2πR = 43.96 m
area = π
= 153,86 m2
Answer:
x>3
Step-by-step explanation:
you divide both sides by 2 then you get three. The sign remains the same.
