Express the following equation in slope intercept form: 8x-2y=10 pleaseeeeeeeeeeee

Sergeu [11.5K]

Answer:

y = 4x–5

Step-by-step explanation:

Slope intercept form is y = mx +b. We can rearrange the equation to fit slope intercept form.

–2y = –8x + 10 (we get this by subtracting 8x from both sides)

In order to isolate the y, we divide both sides by –2.

$\frac{-2y}{-2}$ = $\frac{-8x}{-2}$ + $\frac{-10}{-2}$

–2 divided by –2 equals 1, –8 divided by –2 equals 4, and 10 divided by –2 equals 5.

Therefore, the answer is y = 4x–5.

Underline all the ordered pairs (x,y) that are solutions to the equation y=2x+1.

Romashka [77]

Answer:

(3,7) (7,3) (−1,14) (0,1) (12,25)

(5,11) (0,12) (1,8) (12,0) (−1,−1)

Step-by-step explanation:

We have the following function:

$y = 2x+1$ .

We are going to check if each ordered pair is a solution.

(3,7)

If when $x = 3, y = 7$ , it is a solution.

$y = 2x + 1 = 2(3) + 1 = 7$

This ordered pair is a solution.

(7,3)

If when $x = 7, y = 3$ , it is a solution.

$y = 2x + 1 = 2(7) + 1 = 15$

This ordered pair is not a solution.

(-1,14)

If when $x = -1, y = 14$ , it is a solution.

$y = 2x + 1 = 2(-1) + 1 = -1$

This ordered pair is not a solution.

(0,1)

If when $x = 0, y = 1$ , it is a solution.

$y = 2x + 1 = 2(0) + 1 = 1$

This ordered pair is a solution.

(12,25)

If when $x = 12, y = 25$ , it is a solution.

$y = 2x + 1 = 2(12) + 1 = 25$

This ordered pair is a solution.

(5,11)

If when $x = 5, y = 11$ , it is a solution.

$y = 2x + 1 = 2(5) + 1 = 11$

This ordered pair is a solution.

(0,12)

If when $x = 0, y = 12$ , it is a solution.

$y = 2x + 1 = 2(0) + 1 = 1$

This ordered pair is not a solution.

(1,8)

If when $x = 1, y = 8$ , it is a solution.

$y = 2x + 1 = 2(1) + 1 = 3$

This ordered pair is not a solution.

(12,0)

If when $x = 12, y = 0$ , it is a solution.

$y = 2x + 1 = 2(12) + 1 = 25$

This ordered pair is not a solution.

(-1,-1)

If when $x = -1, y = -1$ , it is a solution.

$y = 2x + 1 = 2(-1) + 1 = -1$

This ordered pair is a solution.

You have 80 ft of fencing to enclose a rectangular yard. the yard is 10 ft wide by 30 ft long. what is the area of the rectangul

Fantom [35]

Hi there!

A=L*W (Area=Length*Width)
*=multiplication

L=30
W=10
A=30*10
A=300ft

Therefore the area would be 300ft

Hope this helps!
