Step-by-step explanation:
Answer:
A
Step-by-step explanation:
(2b-3)^2 = (2b-3)(2b-3) = 4b^2-12b+9
Answer:
15
Step-by-step explanation:
2r=d
r= radius
d=diameter
diameter :30
2r=30
r=30÷2
= 15
Answer:
x = 1
Step-by-step explanation:
-4v+5x=17 give that (x,-3) is the solution
so x coordinate is = x (unknown)
y coordinate is = -3
substitute the value of y in -4y+5x=17
therefore
-4(-3)+5x=17
12+5x=17
5x=17-12
5x=5
x=5/5
x=1
3 because the x value has been repeated
