Answer:

(8,21)

Step-by-step explanation:

Since both equations equal y, set both equaitions equal to each other

and solve for x

4x-11=x+13 , subtract x from both sides

3x-11=13, add eleven to both sides

3x=24, divide both sides by 3 to get x alone

x=8

Substitute x=8 into either equation to solve for y

y=4(8)-11

y=32-11

y=21

Which of the following lines are not parallel to the graph of y = 9x + 1

qaws [65]

Answer:

A. 9y - x = 2

Step-by-step explanation:

9y - x = 2. First to get x on the other side we add x to both sides gettings us this. 9y -x + x = 2 + x or just 9y = x + 2. Then divide by 9 to get y alone. We then get y = x/9 + 2/9. The rate of change is clearly not y = 9x here, it's y = x/9 or 1/9x.

Horace is riding his bike on a bike path. Horace's bike got a flat tire 3/4 of the way down the path and he had to stop. How far

The distance travelled before developing a flat tire illustrates multiplication of fractions

Horace rode a distance of $\frac {9}{16} mile$ before having a flat tire
