Hi!

To solve this, we must make an equation in y = mx + b form, where m is the slope and b is the y-intercept.

Since we are looking at a graph with points, it saves us a TON of work, and all we have to do is simply look at the graph. We only need to find m and b, that's it!

M is the slope, and the slope can be represented by the change between points on a line, also known as <em>rise/run. </em>

If we start at point (-4, -1), and go to point (-2, 0), we can see that it goes up 1 and right 2, which would be represented as 1/2.

B is the y-intercept, and that is simply the point that is on the y-axis, which is the point (0, 1), so our number would be 1.

Therefore, plugging these numbers into the equation, our equation is y = <em>1/2</em>x + <em>1</em>

<em></em>

Hope this helps! :D

AnnZ [28]

Answer:

4V = 3U

Step-by-step explanation:

The final cost of a sale item is determined by multiplying the price on the tag by 75%.

Let us assume that the final cost of the sale item is V and the price on the tag is given by U.

Then the equation that best describes the function that represents the situation is V = \frac{75U}{100} =\frac{3U}{4}

⇒ 4V = 3U  (Answer)

What is the value of n to the nearest whole number?
shtirl [24]

The value of n to the nearest whole number is 22

<h3>Trigonometry</h3>

From the question, we are to determine the value of n to the nearest whole number

In the diagram,

The given triangle is a right triangle.

Thus,

Using the <em>Pythagorean theorem</em>, we have that

n² = h² + k²

∴ n² = 9² + 20²

n² = 81 + 400

n² = 481

n = √481

n = 21.93

n ≈ 22

Hence, the value of n to the nearest whole number is 22

ehidna [41]

Answer:

Let y represents the dog and x represents the Cat.

As per the Statement:

A total of 34 dogs and cats participated in the pet store’s adoption event.

⇒ x+y = 34                 ......[1]

It is also given that the number of dogs that were adopted was 7 more than twice the number of cats.

"Twice times the number of cats" means 2x

"7 more than twice the number of cats means 2x + 7

⇒y = 2x + 7

Then, system of equations are;

x +y = 34

y = 2x + 7

Now, plot the graph of these equation as show below:

The point intersection is, (9, 25) which represents 9 cats and 25 dogs are participated in the pet store's adoption event.
