Answer:

Option B) y=-3x+10 is correct

The equation y=-3x+10 represnts a linear function.

Step-by-step explanation:

To verify that which equation represents a linear function:

Given y=-3x+10

Linear functions are functions whose graph is a straight line. A linear function can be written as y=f(x)=a+bx where x is the independent variable and y is the dependent variable.It has only one independent and dependent variables.

It can be written as y=10-3x

Given equation is also in the form of linear function where a=10 and b=-3

Therefore Option B) y=-3x+10 is correct

The equation y=-3x+10 represnts a linear function.

624 feet to 702 feet state whether the percent of the change is an increase or decrease

Ghella [55]

Answer:

The percent of change is an increase.

Step-by-step explanation:

624 has been changed to 702.

Percent change = [(Value after - Value before ) / Value before]*100

= $\frac{702-624}{624}*100$

= $\frac{78}{624}*100$

So we can clearly see that percentage change is a positive change. This means that the Value after change is higher than value before the change. So the percent of change is an increase.
