What is the equation of this line in slope-intercept form?

1) y= 3x - 1
2) y=-3x - 1
3) y = 3x + 1
4) y=-1/3x-1


Answers

2.) y=-3x-1 and if you look closely you’ll notice the line is going down making it negative and it’s going down by 3 so it’s -3x and when your looking for y just remember you’re looking for the point that’s on the line of y and here you can see the point is on -1 so there’s your answer.

Step-by-step explanation:

A rancher has a square cow pen with side length x. He decides to change the shape

of the pen while still using the same amount of fencing materials. The equation

(x + 10)(x - 10) = 300 represents the relationship of the new side lengths (in feet)

of the pen and its area (in square feet).

a. If 300 represents the area of the new cow pen, what do the expressions

(x + 10) and (x - 10) each represent?

b. Find x, the original side length (in feet) of the square pen. Show your reasoning.

Answers

Answer:

a) x+ 10 is the length of the ranch

x - 10 is the width of the ranch

b) 20 feet

Step-by-step explanation:

Area of the square ranch = L²

L is the side length of the ranch

If the equation

(x + 10)(x - 10) = 300 represents the relationship of the new side lengths (in feet)

Then we can find x where;

x + 10 is the new length of the ranch

x - 10 is the new width of the ranch

Open the parenthesis

equation

(x + 10)(x - 10) = 300

x²²-10x + 10x - 100 = 300

x² - 100 = 300

x² = 300+100

x² = 400

x = √400

x = 20

Hence the original length of the square pen is 20 feet

The values (x + 10) and (x - 10) represents the length and width of the new pen.

The value of x, the original length of the pen is 20 cm

How to find the side of a square?

The pen is a square. It was later reconstructed to form the following expression.

(x + 10)(x - 10) = 300

where

area = 300  feet squared

Therefore,

(x + 10)(x - 10) = 300

x² - 10x + 10x - 100 = 300

x² - 100 = 300

x² = 300 + 100

x² = 400

x = √400

x = 20 ft

Therefore, the original side length of the square pen is 20 ft.

the answer should be 76.333...(nearest tenth 76 ) or 26.

Step-by-step explanation:

since she was already at 151 feet below, I subtracted 229 with 151 and got the answer 78 so after it I just divided it with 3 cause she went down in 3 seconds and the answer could be 76.333 if we dont subtract 229 with 151.

identify the equation of the line having a slope of -3 and a y- intercept of 7

A y + -3x +12
b y = 3x - 7
c y = 3 + 7
d y = -3x + 7

Answers

Answer:

D.

Step-by-step explanation:

We can use the slope-intercept form:

[tex]y=mx+b[/tex]

Where m is the slope and b is the y-intercept.

We know that the slope is -3.

And the y-intercept is 7.

Hence, we will substitute -3 for m and 7 for b. This yields:

[tex]y=-3x+7[/tex]

Therefore, our answer is D.

No explanation required

Answers

Answer:  Yes it is a function.

Reason:

There are no repeated x values, so each x input leads to exactly one y output. That's why we have a function.

If we had something like (1,18) and (1,12), then the input x = 1 leading to simultaneous outputs y = 18 and y = 12 would mean we wouldn't have a function.
