Answer:
x = 9
Step-by-step explanation:
Since we know that the triangle is a right triangle we also know that the angle would be 90 degrees
However we are only given 56 and 3x+7
Let 3x+7 be u
We know that 56+u=90 so solve for u
u=90-56
u = 34
Now u = 3x + 7 so,
3x + 7 = 34
solve for x,
3x=34-7
3x=27
x=27/3
x=9.
Answer:
B. 3x + y = 4
Step-by-step explanation:
y = -3x + 4
Check:
3x + y = 4
<u>-3x -3x</u>
y = -3x + 4
Answer:
34
Step-by-step explanation:
Clean up the equation with x first and x=12.
Substitute this value in to the other equation to solve for y.
You should get a solution of (12,-8)
We just need to do come computation:
So, we have 34>28
