Answer:
C
Step-by-step explanation:
When doing linear equations or quadratics the constant which in this case is +2 means the entire line/parabola is shifted upwards
I can help you with no.1 it is 40
Answer:
a) x = 10 + -1.5y
b) y+15
Step-by-step explanation:
a)2x+3y=10*√4
2x+3y=20
2x + 3y + -3y = 20 + -3y
2x + 0 = 20 + -3y
2x = 20 + -3y
x ÷ 2 = (20 + -3y) ÷2
x = 10 + -1.5y
b)x+2y+5*3=x+y
x+2y+15=x+y
x+2y+15 - y=x+y - y
x+y+15 =x
x+y+15 - x =x - x
y+15
the average rate of change is two
so m=2
Answer:
213 meters squared
Step-by-step explanation:
The surface area of a rectangular prism is found using the formula A=2(wl+hl+hw). Here substitute l = 6, w = 3.5 and h = 9.
A = 2((3.5*6) + (9*6) + (3.5*9))
A = 2(21 + 54 + 31.5)
A = 2(106.5)
A = 213
