Answer:

y = 3x -5

Explanation:

Since it's parallel, it will have the same slope: 3.

So you'll have y = 3x + a, and we need to find a.

Plug in the values for the point we are given:

7 = 3(4) + a

7 = 12 + a

a = -5

<h3>So there you have it: y = 3x - 5</h3>

Answer:

y=3x-5

Step-by-step explanation:

y=3x+6

since the line is parallel, the slope will be the same (but y int is still unsolved)

so plug in x,y from (4,7) in y=mx+b or y-y1=m(x-x1)

i used y=mx+b

7=3(4)+b

7=12+b

b=(-5)

so the final answer is y=3x-5

20 POINTS!

True [87]

Answer:

$y+1=\dfrac{1}{3}(x+2)$ - point-slope form

$f(x)=\dfrac{1}{3}x-\dfrac{1}{3}$ - function notation

Step-by-step explanation:

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

$y-y_1=m(x-x_1)$

m - slope

The formula of a slope:

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

From the graph we have the points (-2, -1) and (1, 0).

Substitute:

$m=\dfrac{0-(-1)}{1-(-2)}=\dfrac{1}{3}$

$y-(-1)=\dfrac{1}{3}(x-(-2))$

$y+1=\dfrac{1}{3}(x+2)$ - point-slope form

$y+1=\dfrac{1}{3}(x+2)$ use the distributive property

$y+1=\dfrac{1}{3}x+\dfrac{2}{3}$ subtract 1 = 3/3 from both sides

$y=\dfrac{1}{3}x-\dfrac{1}{3}$

A contractor charges $273 to tile a 120-square-foot patio and $368 to tile a 170-square-foot patio. The contractor charged a cus

const2013 [10]

To solve this problem you can apply the proccedure shown below:

1. You have that the contractor charges $273dollars$ to tile a $120ft^{2}$ patio and $368dollars$ to tile a $170ft^{2}$ . Then, you have:

$170ft^{2}-120ft^{2} =50ft^{2}$

$368dollars-273dollars=95dollars$

2. As you can see, the price increases $95dollars$ each $50ft^{2}$ . Therefore, based on this, if the contractor charged a customer $539dolllars$ to tile a patio, you can calculate the difference between the first price and this one:

$539dollars-273dollars=266dollars$

3. Then, if the price increases $95dollars$ each $50ft^{2}$ , the area of this patio is:

$A=120 ft^{2}+\frac{(266dollars)(50ft^{2})}{95dollars} \\ A= 260ft^{2}$

The answer is: $260ft^{2}$
