-70
Some actually if it were y=mx+b then it would be the opposite. It would turn positive but I don’t think this one turns like that. I think it’s just -70
Answer:
Step-by-step explanation:
- Start by applying the Euclidien division :
5∧3-9x²-6x+8/(x+1)=(x+1)(5x²-14x+8)
now let's for the factors of 5x²-14x+8 :
- Let Δ be the dicriminant
- a=5
- b= -14
- c=8
- Δ=(-14)²-4*5*8=36 ≥0
So we have two zeros fo this qudratic function x and y :
- x=(14-6)/10=8/10=4/5
- y=(14+6)/10=2
so our factorisation is : (x+1) (x-2)(x-)
Answer:
d
Step-by-step explanation:
3/2 + 1/4 = 6/4 + 1/4 = 7/4
1) you would need to turn both fractions so they have a common denominator, that would be 2 2/4 and 3/4
2) then subtract : 2 2/4 - 3/4, and you would subtract numerators and the whole number, but you keep the denominator the same. However, you cannot subtract 2 and 3 in this case, so you need to change 2 2/4 to 1 5/4 (they are still equivalent)
3) 1 5/4 - 3/4 = 1 2/4, which simplified version is 1 1/2
Therefore, the answer is 1 and 1/2
