Answer:
x = -2
Step-by-step explanation:
The tangent line has length "x + 8"
The secant line has length "x + 6 + 5", where
5 is the inner part
x + 6 is the outer part
Now,
the secant-tangent theorem tells us that square of the tangent line is equal to the outer segment of secant line multiplied by length of whole secant line.
So, we can say:
We can solve for x shown below:
The value of x is -2
Answer:
B) x^2-64
Step-by-step explanation:
Answer:
700$ at 2% 800$ at 4%
Step-by-step explanation:
x+y=1500 This is because the total is 1500 dollars into 2 different accounts, x and y.
0.02x+0.04y=44 This is because it says 2 percent interest in one account and 4 percent in the other, and the totals add up to 44 dollars.
Now use elimination method.
x+y=1500(-0.02)=-0.02x+-0.02y=-30
0.02x+0.04y=44
Now you end up with 0.02y=14, solve for y and you get 700. That's the value of y which now you can then subtract from 1500 and get 800 which is the value of x.
