Answer:

Step-by-step explanation:

The slope-intercept form of an equation of a line:

$y=mx+b$

m - slope

b - y-intercept

We have the slope m = 6, and the y-intercept b = 2.

Substitute:

$y=6x+2$

The perimeter of a rectangle is 80 inches, if the width is 18 inches what is the area of the rectangle? A.22 sq.in B.324 sq.in C

Tanya [424]

Answer:

396 in^2

Step-by-step explanation:

The perimeter of a triangle is given by the formula:

● P = 2w+2L

L is the length and w is the width

■■■■■■■■■■■■■■■■■■■■■■■■■■

The width hereis 18 inches and the perimeter is 80 inches.

Replace w by 18 and P by 80 to find L.

● P= 2L+2w

● 80 = 2L + 2×18

● 80 = 2L + 36

Substrat 36 from both sides

● 80-36 = 2L+36-36

●44 = 2L

Divide both sides by 2

● 44/2 = 2L/2

● 22 = L

So the length is 22 inches

The area of a rectangle is given by the formula:

● A= L×w

● A = 22×18

● A = 396 in^2

And check your answers. At the end of the activity, write a brief evaluation of your work.

Rashid [163]

Answer:

16.5 gallons per minute.

Step-by-step explanation:

The given table is:

$\begin{center}\begin{tabular}{ c c } Time(minutes) & Water(gallons) \\ 1 & 16.50 \\ 1.5 & 24.75 \\ 2 & 33 \\\end{tabular}\end{center}$

We are given this linear function in the form of table.

Let 't' be the time and W(t) be the function with which the gallons of water are changing with time.

We can use slope intercept form to find the equation.

$y=mx+c$

Slope of a function:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

$x_2 = 1.5\\x_1 = 1\\y_2 = 24.75\\y_1 = 16.50$

$m=\dfrac{24.75-16.50}{1.5-1}\\\Rightarrow m =16.5$

This slope is the constant of proportionality.

i.e. the rate at which the number of gallons are changing per minute.

So, the answer is 16.5 gallons per minute.
