Answer:
Step-by-step explanation:
x is tripled so it becomes 3x
it is decreased by 10 so it becomes 3x - 10
so the answer is <u><em>a) 3x - 10</em></u>
hope this helps

Pretend these are coordinates that you can use to find the slope of the line.
(10, 40) and (15, 60). Fit these into the slope formula to find the slope of the line you are looking for:
![m= \frac{60-40}{15-10}](https://tex.z-dn.net/?f=m%3D%20%5Cfrac%7B60-40%7D%7B15-10%7D%20)
and the slope is 4. Now use one of the points and the slope of 4 to solve for b, the y-intercept:
40 = 4(10) + b so b = 0. The equation of the line then is y = 4x + 0 or just
y = 4x

Step-by-step explanation:
I thing use photo math
The first leg of the graph represents Manuel riding his bike for 3 units of time going 5 units distance gradually increasing his speed. The second line segment represents Manuel staying where he his for 4 1/2 units of time. The third represents Manuel going a fast speed back to where he started. I think.
Or the first is him going that distance picking up speed, the second him going a constant speed, and the third him slowing down/speeding up.
