y=-x-4
y=x

solve system of equations algebraically​

Answers

Answer 1

Answer:

y=-2 x=-2

Step-by-step explanation:

y=-x-4

y=x

you can plug y in for x in the first equation by using substitution

y=-y-4

and then you solve for y

2y=-4

y=-2

so y equals -2. Since y=x, x also equals -2. Therefore

y=-2 x=-2

What is the correct answer for both? ​

Answers

Answer:

19)   D (-8, -2)

20)  B (0, 8)

Step-by-step explanation:

-x - y = 10

-6x + 11y = 26

-x - y = 10

-x = 10 + y

x = -10 - y

-6x + 11y = 26

-6(-10 - y) + 11y = 26

60 + 6y + 11y = 26

60 + 17y = 26

17y = -34

y = -2

-x - y = 10

-x - (-2) = 10

-x + 2 = 10

-x = 8

x = -8

_______________

-x + y = 8

3x + 2y = 16

-x + y = 8

y = 8 + x

3x + 2y = 16

3x + 2(8 + x) = 16

3x + 16 + 2x = 16

5x + 16 = 16

5x = 0

x = 0

-x + y = 8

-0 + y = 8

y = 8

What is the value of y in the equation 9 + y = 8? this is extremely time sensitive

Answers

You have to switch the 8 to the left and the y to the right which would change the equation to 9-8=y

y=1

Answer: y =-1

Step-by-step explanation:y =-1

Last option is correct.

Step-by-step explanation:

The given equation is

In order to solve for y, we need to isolate y.

In this equation 9 is added with y and hence in order to eliminate 9 from the left hand side, we do reverse operation of addition.

The reverse operation of addition is subtraction. Hence, we subtract 9 to both sides of the equation

i need help please im only in the 7th grade &’ i don’t know what to do !

Answers

Answer: In the chart, put 6 in place of the question mark.

The equation should be something like w = 2/3 p

W is the number of quarts of water. P is the number of quarts of Pineapple juice.

This week they will need 3 times the previous week so 18 quarts of pineapple juice and 12 quarts of sparkling water.

Step-by-step explanation:

If the basic recipe is 2 water to 3 juice, and they used 4 quarts if water, you can see that is double the amount of water so you need double the amount   of juice. 2 times 3 is 6.

Unit rate means for ONE quart of juice, how much sparkling water is used. that should be  1 Pineapple Juice for 2/3 Sparkling water

OR

for EACH quart of sparkling water, how much juice do you need.

that would be 1 unit of Sparkling Water for 1 1/2 units of Pineapple Juice

If n/8 has a remainder of 5, then which of the following has a remainder of 7?

A) n+1/8

B) n+2/8

C) n+5/8

D) n+7/8

Answers

Answer:

[tex]\frac{n+2}{8}[/tex] has a remainder of 7 ⇒ B

Step-by-step explanation:

In m ÷ n = c + [tex]\frac{r}{n}[/tex] ,

m is the dividendn is the divisorc is the quotientr is the remainderm = (n × c) + r

Let us use the facts above to solve the question

∵ [tex]\frac{n}{8}[/tex] has a remainder of 5

→ Let us find the first number divided by 8 and give a reminder of 5

  that means let the quotient = 1

∵ n = (8 × 1) + 5 = 8 + 5

n = 13

∵ [tex]\frac{n+x}{8}[/tex] has a remainder of 7

→ Let us find the first number divided by 8 and give a reminder of 7

  that means let the quotient = 1

∵ n + x = (8 × 1) + 7 = 8 + 7

n + x = 15

∵ n = 13

13 + x = 15

→ Subtract 13 from both sides

∴ 13 -13 + x = 15 - 13

x = 2

[tex]\frac{n+2}{8}[/tex] has a remainder of 7

Answer:

[tex]a_{n}[/tex] = 22 - 7n

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

8 - 15 = 1 - 8 = - 7

This indicates the sequence is arithmetic with explicit formula

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 15 and d = - 7 , then

[tex]a_{n}[/tex] = 15 - 7(n - 1) = 15 - 7n + 7 = 22 - 7n ← explicit formula

The required value of the expression given of absolute function is 4.25.

Given that,
An expression is given |-4.25|, a simplified value of the expression is to be determined.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
The given expression consists of an absolute function,
So the property of an absolute function is to give an outcome of positive values of the existing value always,
Following the above property,
= |-4.25|
Simplifying
= 4.25

Thus, the required value of the expression given is 4.25.
