B y=14 because if you subtract that will give you the answer
Answer:
78mm^2
Step-by-step explanation:
based on the information given, we can tell that the shape of the MP3 player is a rectangle. The formula for the surface area of a rectangle is SA=2WL+2LH+2HW
SA = Surface Area
W = Width
L = Length
H = Height
SA = 2(4)(7) + 2(7)(1) + 2(1)(4)
= 2(28) + 2(7) + 2(4)
= 56 + 14 + 8
= 78
Answer:
4x7 divided by 9
Step-by-step explanation:
I think it's D.)
Answer:
It is therefore a exponential function, as y increases with x.
Step-by-step explanation:
coordinates: ( 7 , 5 ) , ( 16 , 10 )
Slope: 
: 
: 
equation: y - y1 = m( x - x1 )
: 
: 
check if third coordinates matches:

......does not match, so its not linear.
