Answer:
B. x=6
move all terms to the left that don't contain x to the right side and solve.
Answer:
159 degrees
Step-by-step explanation:
A full semicircle (or half circle) has a degrees of 180. And x is equal that semicircle so x = 180, now if we subtract 21 from 180 we get 159, so X = 159.
Answer:
The missing side is 9cm.
How I got my answer:
1. Squares have equal sides.
2. The area is 81cm^2, so we have to divide 81 by 9.
81 : 9 = 9cm.
Answer:
no they don't
hope this helps
have a good day :)
Step-by-step explanation:
7. y=-3/2x+8 (3rd answer choice)
substitute
-4=-3/2(8)+b
-4=-24/2 +b
-4=-12+b
+12 both sides
8=b
so equation would be...
y=-3/2x+8 (3rd answer choice)
8. y=-5x-17 (2nd answer choice)
substitute
-2=-5(-3)+b
-2=15+b
-15 both sides
-17=b
so the equation would be...
y=-5x-17 (2nd answer choice)
check your work by substituting each (x,y) value into the final equations if you want. hope this helps :))
