Plug the ordered pairs into the equation. The first number represents x, the second number y. The answer is D. -10=5(-2)

Answer:

The answer is d. (-2,-10)

Step-by-step explanation:

In order to determine which ordered pair is a solution of the equation, we have to understand that if we replace the variables into values, the equality must remain. The first value of the ordered pair represents the "x" variable and the second value represents the "y" variable.

So, for every option:

a)

x=-2\\y=10\\\\y=5*x\\10=5*(-2)\\10=-10

There is NOT equality

b)

x=-5\\y=25\\\\y=5*x\\25=5*(-5)\\25=-25

There is NOT equality

c)

x=-3\\y=15\\\\y=5*x\\15=5*(-3)\\15=-15

There is NOT equality

d)

x=-2\\y=-10\\\\y=5*x\\-10=5*(-2)\\-10=-10

There is equality

Finally, the only ordered pair that fulfill the equality is (-2,-10)

in class, matthew stated "i think that a negative is like an opposite. That is why multiplying a negative times a negative equal
sveticcg [70]
Yes and no. A negative number and it's opposite are 'integers.' Yes, a negative and a negative multiplied together give you a positive. The two negative signs cancel out making it positive. But no, a positive and a positive multiplied together do not give you a negative. When you subtract positive numbers you can get a negative, but not when multiplying. If you were to do a positive times a negative it would be negative because the positive can't cancel it out. Example: -3 · -3 = 9. [] 3 · 3 = 9. [] -3 · 3 = -9. Other than the positive number part, the statement is true about the negatives. I hope that helped!

Please help me on this math question?
Whitepunk [10]
M=30° because the right angle and 60 degree angle equal 150 and 180 (degrees in a triangle) minus 150 is 30

n=50° because 40 plus the right angle is 130 then the difference between that and 180 is 50 then n is the vertex angle of the one you found

t=98° because answer n plus the other part to the straight angle including the 112° angle is 68 then the total angle turns to 118 then the final angle turns to 62 via earlier reasoning, then because of another straight angle t=98

use the earlier reasoning to fine the other answers of

p=71°
q=39°

use the angle degrees formula to get Pentagon's maximum angles then use earlier resources

the final answers u should be able to figure out from there and u will never learn unless you do some yourself

Which equations model this problem? A recipe that makes 1 serving calls for 0.1 L of honey. How many servings can Alicia make if
loris [4]
The answer is B. 0.8/0.1 = s

The solution is as follows:
s = honey at hand / honey needed for 1 serving
   = 0.8 L / 0.1 L
   = 8, she can make 8 servings of the recipe

Thank you for posting your question. I hope you found what you were after. Please feel free to ask me more.

Mitchell took a math exam today. If he got 63 out of 84 questions correct, what percentage did Mitchell get wrong? (answer using
Mars2501 [29]

Answer:

75%


Step-by-step explanation:

If Mitchell took a math exam and got 63 out of 84 questions correct, that would turn into the fraction: 63/84

In order to convert this to a decimal, you divide 84 by 63 (since every fraction is a division problem), and get 0.75.

When you change decimals into percents, you move the decimal point two times to the right. So, that would be 75.

Then you add the percent symbol and you're done!

I hope that helped :)
