Answer:
Step-by-step explanation:
10+100=1000
20+100=2000
I think it’s the maximum number of solutions is one
4x²+4x-35=0
factor: (2x+7)(2x-5)=0
2x+7=0, or 2x-5=0
2x=-7 or 2x=5
x=-3.5 or x=2.5
I don't see any rounding necessary in this case.
when you factor ax²+bx+c, you take the two factors of a and the two factors of c, one factor of a times one factor of c, the other factor of a times the other factors, the sum of the two products make b.
in this case, the factors of 4 is 2 and 2, the factors of -35 is -5 and 7. I line them up in the following way:
2 -5
2 7
then I multiple them diagonally, the top left 2 multiplying the bottom right 7=14, and the other 2 multiplying -5=-10, 14 and -10 make a sum of 4.
if you don't get the desired sum, switch the factors up and down till you have the right combination. Note: Do not switch left and right.
I hope this makes sense to you.
x=3.18,x=-5.18
It have two answers
Answer:
<h2>y = 2x - 5</h2>
Step-by-step explanation:
2x - y = 5 <em>subtract 2x from both sides</em>
2x - 2x - y = -2x + 5
-y = -2x + 5 <em>change the signs</em>
y = 2x - 5
