Answer:
-2,0 0,-8 , 2,0 hope that helps
Answer:
x=5, -1
Step-by-step explanation:
I think you mean 2x^2-8x-10=0
2x^2-8x-10=0
Factor out a 2 (0/2 is still 0)
2(x^2-4x-5)=0
Divide by 2
x^2-4x-5=0
Find something that MULTIPLIES to get -5 and ADDS up to get -4, then factor
(x-5)(x+1)=0
Make each set =0
x-5=0
x+1=0
x=5, -1
Answer:you get 0.0347582854x ^127
Step-by-step explanation:
Answer: $70
Step-by-step explanation:
Given that:
Toy with defect is produced once every 4 hours
Cost of labor and supplies incurred for producing a defective toy = $7
Number of defective toys that is expected to be produced in a 40 hour work week :
Number of hours / average hour for producing 1 defective toy
= 40/ 4
= 10 defective toys
Cost incurred for producing 10 defective toys :
($7 * 10) = $70
Answer:
(3,7) is not a solution
Step-by-step explanation:
You fill in the values x=3 and y=7 in both equations and see if you end up with something that is true.
-5·3 - 2·7 = 23 is not true, because it simplifies to -29 = 23
no need to look further, but if you would, the second equation is also false:
3 + 4·7 = -19 is also not true.
The real solution by the way is (-3, -4).
