17. How would you find x and solve for it?
1 answer:
The formula for secant lines is the outside x the overall length is equal to the outside times the overall length of the second line.
A) 5*(x+5) = 6*10
SImplify:
5x +25 = 60
Subtract 25 from both sides:
5x = 35
Divide both sides by 5:
x = 35/5
x = 7
B) 3*8 = 4*(x+4)
Simplify:
24 = 4x +16
Subtract 16 from both sides:
4x = 8
Divide both sides by 4:
x = 8/4
X = 2

5. y = -3 x - 8
6. y = - 1/2 x + 1
X² - 4x - 77 = 0
( x + 7) ( x - 11)
x + 7 = 0
x - 11 = 0
x = -7
x = 11
