Answer:
7a
Step-by-step explanation:
Answer:
A) X + Y = 12
B) 10Y + x = 10x + Y -18
B) 9Y = 9x -18 multiplying A) by -9
A) -9Y = 9x - 72 adding A and B we get
0 = 18x -90
x = 5
The number is 75
Double-Check
7 + 5 = 12
75 -57 = 18
Step-by-step explanation:
Therefore, f(x) = 2x + 3 is your derivative function, and you need to find the original curve. So find the antiderivative using the given conditions...
∫f(x) = ∫2x + 3 dx
F(x) = x^2 + 3x + C
2 = (1)^2 + 3(1) + C
2 = 4 + C
C= -2
Therefore, the curve is F(x) = x^2 + 3x - 2
Proof: The derivative is the slope at every (x, y) point. The derivative of F(x) comes out to be 2x + 3, so we have found the curve. Plug in x = 1, and y = 2, so the conditions have been met.

Meredinth takes 24 minutes to reach her friend house
<em><u>Solution:</u></em>
Given that, Meredith lives 24 blocks from her friends house
She travels one block every minute
<em><u>To find: time taken by Meredith to reach friend house</u></em>
From given,
Number of blocks between Meredith house and her friedn house = 24
She travels one block every minute
Thus she takes 1 minute for 1 block
One block = 1 minute
So, for 24 blocks, we have to multiply by 24

Thus Meredinth takes 24 minutes to reach her friend house
