Answer:
Step-by-step explanation:
Angle PRQ is inscribed in a semi-circle, so the angle is a right angle.
4z - 10 = 90
Add 10 to both sides.
4z = 100
Divide both sides by 4.
z = 25
Divide both sides by :
If , then
and more generally, for any integer ,
63-x=2x+3
-3 +x +x -3
60=3x
60/3 = 3x/3
20=x
To make the equation easier to look at change it to this:
y = 15 - 3x
To find the x intercept say y = 0.
0 = 15 - 3x
Subtract 15 from each side.
-15 = -3x
Divide each side by -3.
5 = x <–––– x-intercept
The y-intercept of the equation is 15.
Hope this helps!
Answer:
This means that he has to save at least $88 or more to have enough money.
Step-by-step explanation:
He has $37 and he needs to save more (+) but we don't know how much more that is, so that's why that is our unknown value. (x). The sum of them has to be at least 125 or greater.
Subtract 37
