5y=-2x+10 but the solution would be x=5,y=2
Answer:
146
Step-by-step explanation:
180=4+30+x
180=34+x
180-34=x
146=x
Answer:
3y
Step-by-step explanation:
(-9x+7y)-(-9x+5y)
Distribute the negative(-)
-9x+7y+9x-5y
-9 and 9 cancel each other
3y
<span>The right function is f(x)=3x^3-10x^2-81x + 28
You can realize that 7 is a root because it is in all the answers.
So you can divide the polynomial by x - 7. If you do it you can find that the quotient is 3x^2 + 11x - 4
Now you can use the quadratic formula to find the other two roots.
If you do it, you will find they are x = 1/3 and x = -4.
So the answer is option A) 7, -4, 1/3
And the polynomial can be written as (x - 7)(x + 4) (x -1/3)
