That would be D because it is the only one which passes the vertical lione test.
Answer:

Step-by-step explanation:
You add the like-terms so the things that are the same, pretty much.
so 3t^2+7t^2 = 10t^2
and you can subtract 8t^2 from 10t^2 because they are like terms so you get 2t^2
then bring -5t down and subtract 9 from 6 and boom you're done
Answer:
The equation in the slope-intercept form will be:
Step-by-step explanation:
Given the points
The slope between two points


As the point-slope form is

substituting the values m = -9/10 and (8, -4)

Writing the line equation in the slope-intercept form

where m is the slope and b is the y-intercept
so the equation in the slope-intercept form will be:


subtract 4 from both sides


Therefore, the equation in the slope-intercept form will be:

Answer:
x=20°
Step-by-step explanation:
(6x+2)° and (5x+22)° are vertically opposite angles, hence VOA angles are equal so
(6x+2)°=(5x+22)°
6x°+2°=5x°+22°.... collect the like terms
6x°-5x°=22°-2°
x°=20°
1.50c would be the proper function for the equation
