Answer:
They should insert that y value into the other equation.
Step-by-step explanation:
The solution is r= 7/a-x How did i do this?
Your equation is ax+ r=7, so the goal is to isolate the r. You begin by dividing the a from the ax. Remember, what you do to one side, you must do to the other. So you do 7/a, since you can't simplify 7/a, leave it as it is. Next, your equation should look like this x+r=7/a. In order to isolate the r, you move the x to the other side by subtracting, which leaves you with the answer of r= 7/a-x.

Answer:
D. 8 cm
Step-by-step explanation:
Reference angle = 60°
Opposite side = BC = 8√3
Adjacent side = AC = ?
Thus:
Tan (60) = opp/adj
Tan (60) = (8√3)/AC
AC*Tan(60) = 8√3
Divide both sides by tan (60)
AC = (8√3)/Tan(60)
AC = (8√3)/√3 (tan 60 = √3)
AC = 8 cm
Answer:
440 Meters
Step-by-step explanation:
The question asks what his altitude was at the beginning, the beginning is the y-intercept and the y-intercept is 440 according to this graph so that's why the answer is 440.
