Answer:
D
Step-by-step explanation:
a^2+b^2=c^2
7^2+9^2=C^2
49+81=c^2
=c
=c
I think the answer is D but i could be wrong
The line passes through (2,-3) and (4,2).
Calculate the slope of the line.
m = (2+3)/(4-2) = 5/2
The equation of the line is therefore
Cross multiply.
2(y-2) = 5(x-4)
2y - 4 = 5x - 20
2y = 5x - 16
Rewrite as
5x - 2y = 16
Answer: C. 5x - 2y = 16
324
Because you multiply 9 by 36
If you did 9 x 6 stamps you would only need 2 x 7 stamps and you would have 2 cents left over
