Answer:
Step-by-step explanation:
x²-bx-22=0
put x=4
4²-4b-22=0
16-4b-22=0
-4b-6=0
2b+3=0
b=-3/2
x²-3/2x-22=0
2x²-3x-44=0
2x²-11x+8x-44=0
x(2x-11)-4(2x-11)=0
(2x-11)(x-4)
roots are 11/2,4
The ratio is 5:39. We cannot simplify it, so the odds are 5:39.
Negative x ( -x) is the opposite of x
When x = 71, then -x would be -71
9-16x^2
This is the answer pretty much the 3 is okay but once you see the four notice there’s - and + you’d multiply it
In this question, you're solving for x.
Solve for x:
x + 4.2 = 7
You need to get x by itself, to do so, you would need to subtract 4.2 from both sides:
x = 2.8
Answer:
x = 2.8
