Answer:
what do we solve x or y?
Step-by-step explanation:
Answer:
10.5
Step-by-step explanation:
Answer:
The slope-intercept form is y = 5/4x - 5/4 and the point-slope form is y - 0 = 5/4(x - 1)
Step-by-step explanation:
There is no such thing as point-intercept form. There is point-slope form and slope-intercept form. To find either of those, you can follow the steps below.
First find the slope of the equation using the slope formula.
m(slope) = (y2 - y1)/(x2 - x1)
m = (5 - 0)/(5 - 1)
m = 5/4
Now we can use the slope along with a point to get the point-slope form.
y - y1 = m(x - x1)
y - 0 = 5/4(x - 1) ------->THIS IS POINT-SLOPE
Now to get slope-intercept, solve for y
y - 0 = 5/4(x - 1)
y = 5/4x - 5/4
It is x=1 because it just is
Answer:
![385\ miles](https://tex.z-dn.net/?f=385%5C%20miles)
Step-by-step explanation:
we know that
I drive 715 miles in 13 hrs
using proportion
Find how many miles would I drive in 7 hrs
Let
x -----> the number of miles
![\frac{715}{13}\frac{miles}{hours}=\frac{x}{7}\frac{miles}{hours} \\ \\x=715*7/13\\ \\x=385\ miles](https://tex.z-dn.net/?f=%5Cfrac%7B715%7D%7B13%7D%5Cfrac%7Bmiles%7D%7Bhours%7D%3D%5Cfrac%7Bx%7D%7B7%7D%5Cfrac%7Bmiles%7D%7Bhours%7D%20%5C%5C%20%5C%5Cx%3D715%2A7%2F13%5C%5C%20%5C%5Cx%3D385%5C%20miles)
