Answer:

equation is y=1.3x-12.4

Step-by-step explanation:

Step one

Given that the points are

(0,7) (8,-2)

X1=0

X2=8

Y1=7

Y2=-2

Step two :

Let us find the Slope

Pluging our points we have

M= (Y2-Y1)/(X2-X1)

M=(-2-7)/(8-1)

M=-9/7

M=1.3

Step three :

We know that the equation of a line is given by

Y=Mx+c

Hence the intercept is

-2=1.3*8+c

-2=10.4+c

-12.4=c

c=-12. 4

Hence the equation is y=1.3x-12.4

in a square garden plot (with an area of 400 sq ft)deer fencing priced at $1.50 per foot is to be installed around the plot. if
mina [271]

We have a square garden of 400 square foot.

The area of a square is:

A=x^2

where x: side length.

In this case:

\begin{gathered} A=400=x^2 \\ x=\sqrt[]{400}=20\text{ ft} \end{gathered}

The perimeter of the square is the sum of the lengths of the sides of the square. As they are all equal, we can write:

P=4x=4\cdot20=80\text{ ft}

The fencing is priced at $1.50 per foot. If we add the 7% sales tax to this price we get:

C=1.50\cdot(1+0.07)=1.50\cdot1.07=1.605\text{ \$/ft}

The fencing will be installed in all the perimeter (80 ft).

We can calculate the total cost by multiplying the sales price ($1.605 per foot) and the perimeter (80 ft):

F=C\cdot P=1.605\frac{\text{\$}}{\text{ft}}\cdot80\text{ ft}=\$128.40

Answer: the fencing will cost a total of $128.40

If you would like to know how many hours did Eric practice the piano this week, you can calculate this using the following steps:

the piano: 3/4 of 8 hours = 3/4 * 8 hours = 6 hours

The correct result would be 6 hours.
