Step-by-step explanation:
6185152673 For the second question and 0/0 is unknown for now
Answer:
units.
Step-by-step explanation:
The given functions are:
![f(x)=3x-7](https://tex.z-dn.net/?f=f%28x%29%3D3x-7)
and
![g(x)=3x+8](https://tex.z-dn.net/?f=g%28x%29%3D3x%2B8)
The function
has y-intercept ,
.
The function
has y-intercept, ![8](https://tex.z-dn.net/?f=8)
If we shift the graph of g(x) up to obtain f(x), then the y-intercept must move from
to
.
This means that the graph will move up by;
units.
3 inches=150 miles
7 inches=350 miles
10 inches=500 miles
Hope this helps!
Answer: y=-7/2x-9/2
Explanation: solving for y=mx+b (linear equation)
m(slope)=y2-y1/x2-x1
(x1= 1, y1=-8),(x2=-1,y2=-1)
M=-1-(-8)/-1-1=7/-2= -7/2
To find the b(y-intercept),use one of the coordinates and plug it into y=mx+b, I will use (x=1,y=-8): -8=-7/2(1)+b
-8/1=-7/2(1)+b/1 -divide the 1 to cancel it and bring it to the other side.
-8+7/2=-7/2+7/2+b -add the 7/2 to cancel it and bring it to the other side.
-9/2=b -b is now isolated and is solved.
So, that’s how you get y=-7/2x-9/2
