Answer 1

Answer:

y=3x-4

Step-by-step explanation:

Answer 2
yo im doing the same thing. To find the slope , All you need to do is to calculate the difference in the y coordinates of the 2 points and divide that by the difference of the x coordinates of the points(rise over run). That will give you the slope. If you want me to tell you the answer i can :)

Answers

Answer:

Step-by-step explanation:

Since this is a test, I'll give a hint:

To find a missing side, you would ussualy use the pythagoream theory, which is not only a pain to write, but pretty easy!

The formula is a^2+b^2=c^2

a and b are the "legs" (the shorter sides) and c is the hypotonus(the longest side).

In this case a=x, and b=6. C=10.

Just input a, b, and c into the equation, and if you have a fairly basic grasph on pre-algebra, then you should be able to solve this.

Hope this helps!

Answer:

8

Step-by-step explanation:

Hi!

So there are two ways to do this, the second way is the easier way

First way:

We can use the Pythagorean Theorem.

If [tex]a^{2}+ b^{2}=c^{2}[/tex]

That means:

[tex]a^{2} = c^{2} - b^{2}[/tex]

Now we plug in the numbers

[tex]x^{2} = 10^{2} - 6^{2}[/tex]

[tex]x^{2} = 100 - 36[/tex]

[tex]x^{2} = 64[/tex]

[tex]x=\sqrt{64}[/tex]

[tex]x=8[/tex]

Second way:

We can use Pythagorean Triplets

We can use the 3,4,5 triplet

We can also put this in a ratio to help you visualize this

3y:4y:5y

Over here, you'll notice that if you make y = 2, then you get this

3(2):4(2):5(2)

Simplify

6:8:10

Well, 6 and 10 are given in this problem so that means that x has to be 8

Let me know if you have any questions

What is the range of the function y = 4x - 7 when the domain is {-2, -1, 3}?

Answers

-15, -11, 5
Hope this helps!:)

The range of the function is {-15, -11, 5}.

What is a function?

A relation is a function if it has only One y-value for each x-value.

To find the range of the function, we need to substitute each value in the domain and evaluate the function.

When x = -2:

y = 4(-2) - 7 = -15

When x = -1:

y = 4(-1) - 7 = -11

When x = 3:

y = 4(3) - 7 = 5

Therefore, the range of the function is {-15, -11, 5}.

Three salesmen work for the same company, selling the same product. And, although they are all paid on a weekly basis, each salesman earns his paycheck differently.

Salesman A works strictly on commission. He earns $65 per sale, with a maximum weekly commission of $1,300.

Salesman B earns a weekly base salary of $300, plus a commission of $40 per sale. There are no limits on the amount of commission he can earn.

Salesman C does not earn any commission. His weekly salary is $900.
The weekly paycheck amount for each salesman, p, is a function of the number of sales, s, they had in that week.

Answers

Answer:

12 sales

Step-by-step explanation:

Let x represent the number of sales each man had.

For Salesman A, he earns $65 per sale; this is 65x.

For Salesman B, he earns $40 per sale; this is 40x.  We also add to this his weekly salary of $300; this gives us 40x+300.

Since their pay was equal, set the two expressions equal:

65x = 40x+300

Subtract 40x from each side:

65x-40x = 40x+300-40x

25x = 300

Divide both sides by 25:

25x/25 = 300/25

x = 12
