Answer:
Step-by-step explanation:
Consider -7-4r=-15. Adding 7 on both sides of the equation,
-4r=-8 --- r = 2
Plug in value of r in r/2 + 9 = 2/2+9 = 1+9 = 10
Solve for the first variable in one of the equations, then substitute the result into the other equation.
(-2,-6)
the answer is
(C) The intervals on one axis do not need to be of equal size.
Answer:
225 square centimeters
Step-by-step explanation:
That whole thing is a right angle, which is 90 degrees. put measure 1 and 2 and equal it to 90 and solve. 5x+x-12=90. combine like terms and solve for x. 6x-12=90. 6x=90+12. 6x= 102. x=17
