Answer:

y-(-20)=1(x-(-10))

Step-by-step explanation:

If you're really in college you should know this, but here's the explanation:

m= <u>-9-(-20)</u>

      1-(-10)

  = <u>11</u>

     11

m = 1

The equation is y-y^1=m(x-x^1)

Replace the y^1, m, and x^1 from the first point

You get y-(-20)=1(x-(-10))

Or simplify that into y+20=x+10

You can also simplify it more but I don't think you need that for that question

Pachacha [2.7K]

Answer: OPTION C.

Step-by-step explanation:

1. To solve this problem you must apply the Pythagorean Theorem, which is shown below:

a^{2}=b^{2}+c^{2}

Where a is the hypotenuse, and b and c are the legs of the triangle.

2. When you solve for one of the legs and substitute values, you obtain that the result is:

b=\sqrt{a^{2}-c^{2}}\\b=\sqrt{(24.8ft)^{2}-(8ft)^{2}}\\b=23.5ft

If your purchases of shoes increase from 9 pairs per year to 11 pairs per year when your income increases from $19,000 to $21,00
Leni [432]

Answer: commom resources good

Step-by-step explanation:

The question above signifies that I can't eliminate shoes from my list. To me, shoes are inexcludable. You can see that as my income increases, my purchases of shoes increase.

I chose common resources good because they are non-excludable (something difficult to eliminate), but can compete with other goods. This means that their availability to other people decreases when they are being used up.

Other types of goods besides common resources good are

- Private goods (products that are easily eliminated and rival)

-Club goods (excludable products but non rival)

-Public goods (unable to eliminate and non-rival)

In the spinner below the large wedges are twice the size of the smaller ones. What is true about the probability of landing on 6
mr_godi [17]

Answer:

A

Step-by-step explanation:

If we take each small section to be "1" unit, we can say the large sections (for "2" and "5") are "2" units each. So in total there will be 8 sections.

Since 5 is "2" sections, we can say:

P(5) = 2/8 = 1/4

And 6 is "1" section, so we can say:

P(6) = 1/8

Definitely, Probability of landing a 6 is HALF that of probability of landing a 5. Also we can see this is the picture.

So, from the answer choices, A is right.

3 times (-8) times (-2)
dexar [7]

Answer:

48

Step-by-step explanation:

Signals during a multiplication of two numbers:

They have the same signal: The multiplication is positive.

They have different signals: The multiplication is negative.

3 times (-8) times (-2)​

First 3*(-8):

Different signals, so negative. 3*8 = 24. So the answer is -24.

Then:

3*(-8)*(-2) = (-24)*(-2)

Same signal, so positive. 24*2 = 48. The answer is 48.

Choose the equation below that represents the line passing through the point (2, -5) with a slope of -3.
mash [69]
The point-slope form: y-y_0=m(x-x_0)

m=-3;\ (2;-5)\to x_0=2;\ y_0=-5

subtitute

y-(-5)=-3(x-2)\\\\y+5=-3x+6\ \ \ \ \ |subtract\ 5\ from\ both\ sides\\\\\boxed{y=-3x+1}
