Answer:
Excluded Value : 3 and -5
Step-by-step explanation:
hello :
Excluded Value : and
the excluded value when : x²+2x-15=0
(
x²+2x+1)-1-15=0
means : (x+1)²-16=0 (x+1)²-4² = 0
by identity : a²-b² =(a-b)(a+b)
(x+1-4)(x+1+4) =0 so : (x-3)(x+5) =0 means : x-3=0 or x+5=0
x=3 or x= -5
Excluded Value : 3 and -5
Answer:
(-5, 3)
Step-by-step explanation:
it translated left 2 units => x'= x-2
down 2 units=> y'= y-2
Answer:
Let b = profit on a blue car
w = profit on a white car
r = profit on a red car
b = w + 10 (1)
r = w - 7 (2)
2r = b -2
2r-b= -2 (3)
Subtract eq. (2) by 2q. (1)
r - b = 0 - 7 - 10
r - b = -17 (4)
Subtract eq. (3) by eq. (4)
r - 0 = -2 - (-17)
r = 15
in eq (2)
r = w - 7
15 = w - 7
w = 22
in eq (1)
b = w + 10
b = 22 + 10
b = 32
The profit on a blue car is $32
Step-by-step explanation:
THE ANSWER IS 32
17, 29-5=24
24/2=12
12
12+5=17
To simplify this:
You can factor the denominator and then cancel out some terms. But, this is not factorable. So, I think you are missing a term or you wrote this wrong.
