Let's prove each one:
A) y=x-3
x=0→y=0-3→y=-3=-3 ok
x=2→y=2-3→y=-1 different to 5 No
B) y=x+3
x=0→y=0+3→y=3 different to -3 No
C) y=4x-3
x=0→y=4(0)-3=0-3→y=-3=-3 ok
x=2→y=4(2)-3=8-3→y=5=5 ok
x=3→y=4(3)-3=12-3→y=9=9 ok
x=4→y=4(4)-3=16-3→y=13=13 ok
D) y=4x+3
x=0→y=4(0)+3=0+3→y=3 different to -3 No
Answer: Option C) y=4x-3
Answer:
B. 523.33 cubic units
Step-by-step explanation:
The volume of a sphere is given by
V = 4/3 pi r^3
V = 4/3 (3.14) 5^3
V =523.3333333
V = 523.33 units^3
Answer:
A. X=-3
Step-by-step explanation:
16x-4+5x=-67
21x=-67+4
21x=-63
Divide through by 21
X=-3
308 well that's all too that.
Answer:
$1.13
Step-by-step explanation:
x/11.31 = 10/100 (cross multiply)
100x = 113.1 (divide by 100)
x = 1.131
