Answer:
x = 8.5
Step-by-step explanation:
I got this answer by assuming the triangles were congurent, if they are not, the answer may vary.
first, make an equation:
x + 8 = 3x - 9
bring 3x to the other side, by subtracting it
-2x + 8 = -9
Subtract 8
-2x = -17
divide by -2
x = 8.5
Then, just sub x into the formulas

If the center of the cercle is (0,0) then the standard equation becomes"
x²+y²=(4.5)²
Answer:
|−∣=7
Explanation:
∣−∣
= |(-2-5)|
= |-2-5|
= | -7|=7
Answer:
y=-3x
Step-by-step explanation:
Slope intercept form is written as y=mx+b, where:
m= slope
b= y-intercept
We know the slope and y intercept already, so simply plug them in:
y=-3x+0
We can remove the +0 because it is redundant, therefore the final answer is:
y=-3x
