3x - 2y = 8
2x + 2y = -8

Answers

Answer 1

Answer:

(0, - 4 )

Step-by-step explanation:

3x - 2y = 8 → (1)

2x + 2y = - 8 → (2)

Adding (1) and (2) term by term will eliminate the y- term

5x + 0 = 0

5x = 0 , then

x = 0

Substitute x = 0 into either of the 2 equations and solve for y

Substituting into (2)

2(0) + 2y = - 8

0 + 2y = - 8

2y = - 8 ( divide both sides by 2 )

y = - 4

solution is (0, - 4 )

Answer 2
1. y=3/2x-4
2. y=-1x-4
Hope this helps :)

what is 5x – 9 + 2x – 4 = 9.4

Answers

Simplifying
5x + -9 = 38

Reorder the terms:
-9 + 5x = 38

Solving
-9 + 5x = 38

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '9' to each side of the equation.
-9 + 9 + 5x = 38 + 9

Combine like terms: -9 + 9 = 0
0 + 5x = 38 + 9
5x = 38 + 9

Combine like terms: 38 + 9 = 47
5x = 47

Divide each side by '5'.
x = 9.4

Simplifying
x = 9.4

Answers

Answer:

-6

Step-by-step explanation:

g(-4) here x = -4

So, we have to take g(x) = x - 2

g(-4) = -4 -2 = - 6

g(1) , here x = 1 ,

So, we have to take g(a)= -x +1

g(-1) = -1 + 1 = 0

g(-4) + g(-1) = -6 +0 = -6

If x = 1, y = 7, and z = 15, determine a number that when added to x, y, and z yields consecutive terms of a geometric sequence. What are the first three terms in the geometric sequence? 3

Answers

Given:

[tex]x = 1, y = 7,z = 15[/tex]

A number is added to x, y, and z yields consecutive terms of a geometric sequence.

To find:

The number which is added to  x, y, and z, then find the first three terms in the geometric sequence.

Solution:

Let the unknown number be k.

After adding k to x, y, and z, we get

[tex]x = 1+k, y = 7+k,z = 15+k[/tex]

These are the consecutive terms of a geometric sequence. So,

[tex](7+k)^2=(1+k)(15+k)[/tex]

[tex]49+14k+k^2=15+k+15k+k^2[/tex]

[tex]49+14k=15+16k[/tex]

Isolate the variable terms.

[tex]49-15=16k-14k[/tex]

[tex]34=2k[/tex]

[tex]\dfrac{34}{2}=k[/tex]

[tex]17=k[/tex]

The unknown number is 17.

Now,

[tex]x=1+k[/tex]

[tex]x=1+17[/tex]

[tex]x=18[/tex]

Similarly,

[tex]y=7+k[/tex]

[tex]y=7+17[/tex]

[tex]y=24[/tex]

And

[tex]z=15+k[/tex]

[tex]z=15+17[/tex]

[tex]z=32[/tex]

Therefore, the three terms in the geometric sequence are 18, 24, 32.

Zeke earned 23 extra credit points. Sofia earned e fewer extra credit points than Zeke. Write
an expression that shows how many extra credit points Sofia earned.

Answers

Answer:

s = 23 - e

Step-by-step explanation:

In this expression, s is equal to the amount of extra credit Sofia earns. She earns e less points than the 23 points Zeke earns.

So, s (Sofia's points) = 23 (Zeke's points) - e (the difference in points).

The expression is s = 23 - e.

Rewrite without absolute value for the given conditions:
y =|x −3|+|x +2|−|x −5|, if x < −2

Answers

Answer:

y = -x - 4

Step-by-step explanation:

y =|x −3|+|x +2|−|x −5|, if x < −2

let x = -1

y1 =|x −3|

y1 = - ( x - 3 ) = -x + 3

y2 = |x +2|

y2 = - (x +2) = -x - 2

y3 = |x −5|

y3 = - (x −5) = -x + 5

y = y1 + y2 + y3

substitute back into original

y = -x + 3 - x - 2 - (-x + 5)

y = -x + 3 - x - 2 + x - 5

y = -x - 4

Solve the equation using the distributive property and properties of equality. 2 (x minus 8) = 68 What is the value of x?

Answers

Answer:

x=42

Step-by-step explanation:

2(x-8)=68

Distribute the 2

2x-16=68

Use the addition property of equality (add 16 to both sides)

2x=68+16

2x=84

Use the division property of equality (divide both sides by 2)

x=84/2

Marcy needs 150 feet of fabric for her project. She uses 20% of it. How many feet of fabric did she use for her project so far? You may use a bar model or double number line.

Answers

Answer:

The answer is 120 feet of fabric

Answer:

30 feet.

Step-by-step explanation:

Steps

First, convert the percentage discount to a decimal. 20 percent of 150 is 0.20 in decimal format.

Secondly, multiply the decimal discount by the price of the item to determine the savings in dollars.

In this case, the original fabric needed equals 150 feet, you would multiply 0.2 by 150 to get the answer.

Solution

20 percent *150 =

(20:100)*150 =

(20*150):100 =

3000:100 = 30

Therefore, she used 30 feet for her project so far.
