Answer:
r=2
Step-by-step explanation:
r + 11 + 8r = 29
add the like terms
r+8r+11=29
9r+11=29
then subtract 11 on both sides to eltimate 11
9r=18
lastly divide 9 on both sides
r=2
Answer:
The radius is 7.23units
Step-by-step explanation:
Check image below for solution
Here, 0.625x - y = -9.625
y = 0.625x + 9.625
Substitute the value of y in 2nd equation,
-65x - (0.625x + 9.625) = -5
-65x - 0.625x -9.625 = -5
-65.625x = 9.625 - 5
x = -4.625/65.625
x = -0.070
Now, substitute it in first equation,
-65(-0.070) - y = -5
4.58 + 5 = y
y = 9.58
In short, Your Answer would be: (-0.070, 9.58)
Hope this helps!
