Answer:
D
Step-by-step explanation:
use the formula for point slope form, since all of your choices are in that form : y-y1=m(x-x1) (m is the slope)
we're given that m=2 and the point is (2,9)
Substitute into the equation
y-9=2(x-2)
That means that the answer is D
Hope this helps!
Answer:
Mary's brother practiced 4 times as long.
Step-by-step explanation:
Mary practiced violin for 2 hours.
Her brother practiced trombone t times as long or 8 hours.
t times of 2 hours = 2t hours
But, 2t = 8
Divide both sides by 2.
t = 4
Hence, Mary's brother practiced 4 times as long as Mary.
A=p(1+r)^t
A=15,000×(1+0.06)^(5)
A=20,073.38
Answer:
4. j(11) = 8
I think it is linear
5. g(-3) = 18
No, it's a parabola since x is to the second power
6. f(-7) = 5
No, I think it's an absolute value function
7. h(0) = 13
I think it is linear, just the slope is 0
