Answer:

a) Yes.

Step-by-step explanation:

A function does not have any repeating values for a given x-value. According to the values of the table, there aren't multiple y-values for a given x-value. Therefore, the table represents a function.

Write an equation of a line with slope -1 that contains point P(2,-4)

Maurinko [17]

Explanation:

The slope-intercept form of a line is:

y=mx+b

where:

m is the slope of the line

b is the y-intercept

We are given that m=4 and the line passes through (7,2).

∴2=4⋅7+b

2=28+b

b=−26

Therefore the equation of the line is:

y=4x−26

graph{y=4x-26 [-1.254, 11.23, -2.92, 3.323]}

Answer:

112 ft

Step-by-step explanation:

9) Here, we are finding the area of a triangle. The equation for area is:

$A = \frac{1}{2} *b*h$

Where A is area, b is the base, and h is height.

$A = \frac{1}{2} * 16 * 14$

$A = 112$
