Answer:
X3
Step-by-step explanation:
6x3=18
5x3=15
4x3=12
H(17) = 17
Do you need help with the other 2?
Answer:
y=2x+1
Step-by-step explanation:
First you have to find the slope:
5-1/2 so 4/2 or 2
Then you write it in point-slope: (I used the point (0,1))
y-1=2x
Simplify than:
y=2x+1
Answer:
D
Step-by-step explanation:
Plug (5, 7) & (8, 13) into each equations and see which one of them makes mathematical sense. You'll find out that y=2x-3 is the right answer.
This is indeed a linear equation. y-4x=9 in standard form is y=4x+9.
