Answer:
D. 9
Step-by-step explanation:
The segment lengths are equal, so ...
x^2 = 90-x
x^2 +x -90 = 0 . . . . . . add x-90 to put in standard form
(x +10)(x -9) = 0 . . . . . factor
The solutions are the values of x that make the factors zero: -10, 9.
The positive value of x is 9.
Answer:
the equation would be f(x)= -9x+3 or y=-9x+3
Step-by-step explanation:
Answer:
3x+30= 116° 2x=64°
Step-by-step explanation:
the angle below 2x is the same as 3x+20 so we know that 5x+20=180 so solve this
5x+20=180
5x=160
x=32
sub x into the angle equations
3(32)+20=116
2(32)=64

Step-by-step explanation:
5/6 = x/24
6 times 4 is 24
(you have to times denominator and numerator by the same number)
5 times 4 = 20'
it would be 20/24
