Answer:
Table B
Table C
Table A
Step-by-step explanation:
Substitute by the easiest number which is 0
f(0) =2(0) - (-3) =3 Then it is Table B function
f(0) = -2(0) +(-1/3)= -1/3 Then it is Table C function
f(0) =2(0) +(2/3)=2/3 Then it is Table A function
No it is not, the solution would need to be (2,-4) in order to satisfy the equation y = -2x -- like so -4 = -2(2)
-4 = -4, otherwise the equation won't be satisfied.
Answer: x>-6
Explanation: -2x -6>-18
-2x >-12
-x>6
X>-6
Answer:
<u>4 hours</u>
Step-by-step explanation:
Equations :
Larry : <u>y = 20x + 90</u>
Barry : <u>y = 30x + 50</u>
Equate both to find the number of hours at which they both charge the same :
- 20x + 90 = 30x + 50
- 30x - 20x = 90 - 50
- 10x = 40
- x = <u>4 hours</u>
