Hi
f(x) = g(x) if -x²+3x-2 - ( -x+1) = 0
-x² +3x-2 +x-1 = 0
-x² +4x -3 = 0
To solve, tou have to use the general method of resolution of a quadratic fonction.
To determine if it's has a solution in R, let's calculate Δ
Δ = (4)² - 4 * (1) *(-3)
Δ = 16 +12
Δ= 28
as Δ≥ 0 so the function allow two solution within R
so S 1 = ( -4 +√28) / 2 S 2 = (-4 -√28 ) /2
S1 = ( -4 + 2√7) /2 S2 = (-4 - 2√7) /2
S1 = (2 (-2 +√7) /2 S2 2 (-2 -√7) /2
S1 = -2 +√7 S2 = -2 -√7
So the two function are equal twice. one for x = -2 +√7 and second x = -2-√7
Answer:(7)2+6=20
Step-by-step explanation:what times (?) Times 2 +6 will give you twenty
7×2=14 14 + 6 = 20
I’m sort of confused. Do you mean how many cups of fruit juice she’ll get if she uses 2 cups of pineapple juice? If so it should be 3.
-27 minus 10 isn't -17....its -37 so since that mistake everything else is counted as a mistake
Hope this helps
