You can do substitution 2x-2=x^2 -x -6; isolate all terms on one side 0= x^2 -x-2x -6+2; combine like terms x^2 -3x -4=0; factor the quadratic (x-4)(x+1)=0; each term is zero x-4=0 so x=4 and x+1=0 so x=-1. Now, y=2•4-2=6 and y=2•(-1) -2= -4 ; solutions for the system are ( 4,6) and ( -1, -4)
5/11 as a decimal is 0.45 and it just repeats
We are given
two ratios as
First ratio:
we can simplify it
Second ratio:
we can simplify it
we can cancel 4
so, both ratios are same
so, they are proportional..........Answer
Answer:
x>−2
Step-by-step explanation:
1 Subtract 1010 from both sides.
3x>4-103x>4−10
2 Simplify 4-104−10 to -6−6.
3x>-63x>−6
3 Divide both sides by 33.
x>-\frac{6}{3}x>−
3
6
4 Simplify \frac{6}{3}
3
6
to 22.
x>-2x>−2
