22/32 = 100/x
22x = 100(32)
22x = 3200
x = 3200/22
x = 145.45 ft
Answer: Slope is undefined. x=0
slope calculation: -3-4/0-0 = -7/0 and anything divided by 0 is undefined
the x value in the coordinates is 0 so it’s x=0 line.
vertical lines always have undefined slopes
Answer:
x = approx. 1.24 or -7.24
Step-by-step explanation:
It's hard to factor directly so we should use the quadratic formula or complete the square. I'm going to go with completing the square.
x²+6x-9=0
x²+6x=9
x²+6x is the same as x²+2·3·x, in order to make this into the algebraic identity (A+B)²=A²+2AB+B², we must add B², or in this case 3² to both sides. (A is x, B is 3)
x²+6x+9=18
(x+3)²= 18
x+3= ±√18
x= ±4.24 -3 (approximately 4.24)
First solution for x = 4.24-3 = 1.24
Second solution for x = -4.24-3 = -7.24
Answer:
it equals 89/90
Step-by-step explanation:
the gcf of 89, 90 is 1, so the fraction can not be simplified. The answer is 89/90.
Coefficients are the numbers in from with the variable, the constant is just a number and the degree is the exponent.
