Make sure to enter your answer as an ordered pair. (x,y)

Answers

Answer 1

Answer:

(12, -23)

Step-by-step explanation:

Equate the equations:

y = y

⇒ -3x + 13 = -2x + 1

Add 3x to both sides:

⇒ -3x + 13 + 3x = -2x + 1 + 3x

⇒ 13 = 1 + x

Subtract 1 from both sides:

⇒ x = 12

Substitute x=12 into one of the equations to find y:

⇒ -2(12) + 1 = -23

Therefore, the ordered pair is (12, -23)

Answer 2

(X,y)=(12,-23)
All you had to do was solve for x first and once you found your answer plug it in for x and then solve for y

What is Number system?

A number system is defined as a system of writing to express numbers.

Reciprocal is simply defined as the inverse of a value or a number.

If n is a real number, then its reciprocal will be 1/n.

In other words the reciprocal of a number is simply "1" divided by that number. So, the reciprocal of 10 is 1/10.

To see why this is the case, you can think of division as the opposite of multiplication. If you multiply 10 by its reciprocal, you should get the number 1. That is:

10 x (1/10) = 1

So, 1/10 is the reciprocal of 10.

The radius of a circle is 5.6 feet. Find the diameter.

Answers

Answer:

11.2

Step-by-step explanation:

Radius = 5.6
Diameter = r x 2
= 5.6 x 2
= 11.2

Answer:

11.2 feet

Step-by-step explanation:

To find the diameter of a circle from the radius you must multiply the radius by 2 so the formula would look like r x 2= D and the equation would look like 5.6 x 2=D = 11.2

A home furnishing store sells 6 chairs for $900. Martin buys 2 such chairs for her new home. How much did she spend on the purchase?

Answers

$300 if it is $900 for 6 chairs

if it is $900 each(expensive chairs), it would be $1800

Answer:

$300

Step-by-step explanation:

It would be $300 dollars for 2 chairs because $900 dollars divided by 6 = 150 so each chair is $150. Since we are buying 2 chairs it would be 150 time 2 which equals 300. So she spent $300 on her purchase.

help me find x pls im so confused even my mom cant do it pls

Answers

-3x + 7 = -1
-3x = -8
x = 8/3

In order to solve for x, you must isolate the variable. Because -1 and 7 are like terms, use inverse operations to subtract 7 from both sides. Then, divide both sides by -3. This should get you x = 8/3, which can’t be reduced any more (unless you convert to decimal, which is about 2.666666…) Feel free to comment any questions you have! Always happy to help :)

when might you need to round the quotient when dividing a decimal by a whole number

Answers

Rounding Decimals When Dividing. You can divide decimals by whole numbers and use zero placeholders to find the most accurate quotient. Some quotients are so long that it is difficult to decipher the value of the decimal. Rounding the decimal number to a decimal place value would make the number easier to evaluate.

−3

Answer:

5-(-9) = 14

-6-(-3) = -3

Step-by-step explanation:

So for the first one -1-(6), when you have two negatives next to each other then it turns into a plus. So when it turns into a plus. So when it turns into a plus we will have 5+9. And here we have the same signs so we are gonna add and 5+9=14. So the answer is 14.

Now for the second one -6-(-3), the same thing when you have two negatives next to each other then it turns into a plus. And when it turns into a plus we will have -6+3. Now although there is a plus sign we are not gonna add because both number do not have the same sign. So we are gonna subtract and take the sign of the bigger number. And now -6+3=-3 so our answer is -3.

This is fantastic news for all chocolate lovers. The extensive research was conducted over eight years. The research team followed the chocolate-eating habits and health of almost 20,000 people. They compared how much chocolate was in their diet to the number of heart attacks and strokes people had. Lead researcher Brian Buijsse said: "The good news is that chocolate is not as bad as we used to think, and may even lower the risk of heart disease and stroke." Mr Buijsse said his team found that dark chocolate was the healthiest kind to eat: "Dark chocolate exhibits the greatest effects, milk chocolate fewer, and white chocolate no effects, he said.The German study showed that people who ate the most chocolate (at least one bar per week) reduced their risk of having a heart attack by 27 per cent. The risk of suffering a stroke was cut by as much as 48 per cent. Nutrition experts believe that natural compounds in chocolate called flavonols are good for our heart. Flavonols also help reduce blood pressureThey are found in cocoa beans so dark chocolate (which has more cocoa) contains more of them than milk chocolate (which has more fat).
