Mathematics

Answer:

Point slope form:y-3=4x+2

slope intercept form: 4x + 11 = y

Step-by-step explanation:

(-2,3)

-2=x1

3=y1

m=4

(y - y1) = m(x - x1)

-point slope form equation

(y - (3)) = 4(x - (-2))

- substitute values

y-3=4x+2-simplified equation

slope intercept:(to find intercept of slope you need to know where the slope begins)

find "b" first in y=mx+b:

and y1 as "y"

take(x1) as "x"- this is because (-2,3) is an x,y pair and we have an x and an y in "y=mx +b"

(3)=4(-2)+b

3=-8+b

add "8" to both sides

3+8=-8+8+b

11=b

since we know be we can solve for the y intercept in "y=mx+b"

y=4x+11-this is the "y" intercept

so slope intercept form= y=4x+11

hope this helps

Answer:

y-3 = 4(x+2)  point slope form

y = 4x+11  slope intercept form

Step-by-step explanation:

Since we have a point and a slope, we will start with point slope form

y-y1 = m(x-x1)

y-3 = 4(x--2)

y-3 = 4(x+2)

This is point slope form

Distribute

y-3 = 4x+8

Add 3 to each side

y-3+3 = 4x+8+3

y = 4x+11

slope intercept form

Stephon has a square brick patio. He wants to reduce the width by 4 feet and increase the length by 4 feet.
alekssr [168]

Answer:  The expressions for the length and width of the new patio are

\ell=x+4,~~w=x-4.

And the area of the new patio is 384 sq. feet.

Step-by-step explanation:  Given that Stephen has a square brick patio. He wants to reduce the width by 4 feet and increase the length by 4 feet.

The length of one side of the square patio is represented by x.

We are to write the expressions for the length and width of the new patio and then to find the area of the new patio if the original patio measures 20 feet by 20 feet.

Since Stephen wants to reduce width of the patio by 4 feet, so the width of the new patio will be

w=(x-4)~\textup{feet}.

The length of the patio is increased by 4 feet, so the length of the new patio will be

\ell=(x+4)~\textup{feet}.

Now, if the original patio measures 20 feet by 20 feet, then we must have

w=x-4=20-4=16~\textup{feet}

and

\ell=x+4=20+4=24~\textup{feet}.

Therefore, the area of the new patio is given by

A_n=\ell \times w=24\times16=384~\textup{sq. feet}.

Thus, the expressions for the length and width of the new patio are

\ell=x+4,~~w=x-4.

And the area of the new patio is 384 sq. feet.

Help me please !!!!!!
kirill115 [55]

Answer:

The y-int represents the base price of $200 for airfare from NYC

The slope represents a cost of 30 cents per mile traveled

If the base cost for airfare changed to $50 and the cost per mile is unchanged, the new equation would be y=50+0.30x

If the cost per mile changed to 50 cents, the new equation would be y=200+0.50x

What is the value of y in the equation 2(3y + 4 + 2) = 196 − 16?<br><br> 26<br> 28<br> 30<br> 32
koban [17]

Answer:

28

Step-by-step explanation:

2(3y + 4 + 2) = 196 − 16

6y + 8 + 4 = 196 - 16

6y + 12 = 196 - 16

6y + 12 = 180

6y = 168

y = 28

Best of Luck!
