Step-by-step explanation:
The vertex is the point (-4, 7).
Answer:
The density of cube is 6.17959 
Step-by-step explanation:
The density is given by ration of a mass of body and volume occupied by a body.
Where,
is density.
m is mass of a body
V is the volume of a body
Given that one side of the cube is 0.53cm
Hence, the volume of a body is V=
=0.148877
Now, the Density of the cube will be
Thus, The density of cube is 6.17959
Answer: y = -2x + 8
Step-by-step explanation: Subtract 2x from both sides to get (y) by itself. 2x is the slope and 8 is the y-intercept. Brainliest please?
If y is 5 when x is 2.5 and y varies directly with x, find y when x is 10.
The term "y varies directly with x" means that the formula is a direct variation. We need to look for the constant of variation.
y = kx ; where k is the constant of variation.
k = y/x
k = 5/2.5
k = 2
We then use the direct variation formula to get the value of y when x is a certain number.
y = kx
y = 2 * 10
y = 20
