Answer:
No
Step-by-step explanation:
x y
y = - 3(-2) + 1 = 7 -2 7
y = -3(0) +1 = 1 0 1
y = -3(1) + 1 = -2 1 -2
y = -3(3) + 1 = -8 3 -8
Answer:
X= -45
Step-by-step explanation:
Subract 23 from both sides to solve for x.
(-4,0) (-3,3) (-1,0) (0,-3) (1,-5) (3,0)
So, domain numbers are -4, -3, -1, 0, 1, 3
Range are 0, 3, -3,-5,
Just take the ordered pairs and the Xs is the domain and the Ys are the range
X=4
After squaring both sides, you get
4(x+5)=x^2-20x+100
Multiply
4x+20=x^2-20x+100
Collect like terms
4x+20-x^2+20x-100=0
Reorder
24x-80-x^2=0
Change signs & Write as difference. You end up with
x^2-4x-20x+80=0
Factor
x-4=0 , x-20=0
4=4 , 0=20
x=4
The answer is -20.
The negative part shows the loss and 20 is the amount of money
