Answer:
Yes.
Step-by-step explanation:
To find the point of intersection we solve the system:
y = x + 3
y = -x + 7 Subtract:
0 = 2x - 4
2x = 4
x = 2.
She is correct.
Answer:
8
Step-by-step explanation:
Let's call the missing side as x
Base on the pythagorean theorem, we have :
17² - 15² = x²
289 - 225 = x²
x² = 64
So, x equals 8.
Hope it helps
The answer will be 8.39 because the third number (8) is above 5 so you have to round up. Good luck!
Answer:
x = 29
Step-by-step explanation:
I think this because they give you 78 degrees. The angle across from it (3x - 9) must equal 78 degrees as well. So solve as (3x - 9) = 78. 78 + 9 is 87. 87 divided by 3 is 29.
Hope it helps and is correct!
Answer:
u = 8
Step-by-step explanation:
3u + 5u = 64
8u = 64
8u/8 = 64/8
u = 8
