How Do I Solve This Using Substitution??

Answers

Answer 1

Answer:

-1

Step-by-step explanation:

so -x-6 and x-4 are both = to y so that means they are both = to each

other so -x-6=x-4 add x to both sides -6=2x-4 add 4 to both sides 2x = -2 simplify by divide by 2 so x=-1

Answer 2

Answer:

Take the second equation and add 4 to both sides, this gives you x=y+4. The plug in y+4 on the first equation, so y=-(y+4)-6, distribute the negative to everything inside the parentheses, and you get y=-y-4-6. Combine like terms and you get y=-y-10, then add y to both sides, you get 2y=-10, divide both sides by 2 and you get y=-5.

Then plug -5 into the second equation and you get -5=x-4, add 4 to both sides and you get -1=x.

If you want to check your answer, just plug in x and y to either of the equations and see if it makes a true statement.

2x² + 3 = 39 extracring square roots

Answers

Answer:

x=9

Step-by-step explanation:

first, subtract 3 from both sides so 2x^2=36, then, divide both sides by 2 so x^2=18 and divide 18 by 2 and 9^2=18

Answer:

x = ± 3[tex]\sqrt{2}[/tex]

Step-by-step explanation:

2x² + 3 = 39 ( subtract 3 from both sides )

2x² = 36 ( divide both sides by 2 )

x² = 18 ( take square root of both sides )

x = ± [tex]\sqrt{18}[/tex] = ± [tex]\sqrt{9(2)}[/tex] = ± ( [tex]\sqrt{9}[/tex] × [tex]\sqrt{2}[/tex] ) = ± 3[tex]\sqrt{2}[/tex]

Answers

the answer will be

48$ dollars

Answer:

20 + 6x

$44

Step-by-step explanation:

So 5 CD's for 20 dollars is $4 ea. then each one added will be +6 with the variable (x).

so you can't have the first 5 becuase x is used for every one OVER 5.

So

$ or price = 20 + 6x

plug 4 in because 9-5 = 4

20 + 6(4)

The area of this polygon is 228 square meters
What is the length of the side labeled with a question mark
Enter your answer in the box

Answers

Answer: 7

Step-by-step explanation:

Let the unknown length be x

Cut the polygon into 2 pieces

6 * 24 + x * (18 - 6) = 228

144 + 12x = 228

12x = 84

x = 7

The length of the side labeled with a question mark in the given polygon is 7 meters.

What is area?

Area is the amount of space occupied by a two-dimensional figure. In other words, it is the quantity that measures the number of unit squares that cover the surface of a closed figure. The standard unit of area is square units which is generally represented as square inches, square feet, etc.

Given that, the area of this polygon is 228 square meters.

We know that, the area of a rectangle is Length×Breadth

Area of a large rectangle = 24×6

= 144 square meters

Let the length of unknown side be x.

Area of a small rectangle = 12×x

Total area = Area of a large rectangle+Area of a small rectangle

228=144+12x

12x=228-144

12x=84

x=84/12

x=7 meters

Therefore, the length of the side labeled with a question mark is 7 meters.

I'm going to do 1 as an example and using what I've taught you, you have to do the rest. Hope my explanation helps.

Step-by-step explanation:

We are given the points (-2, -4) and (-1, -1)

We need to find the slope.

The equation to do so is y2 - y1 / x2 - x1

lest say:

-2 is x1

-4 is y1

-1 is x2

-1 is y2

-1 - (-4) / -1 - (-2)

3/1 = 3

slope (m) = 3

We already know the y-intercept is 2

The equation of a line is y = mx + b

For this problem we just have to substitute what we already know.

y = (slope)x + y-intercept

y = 3x + 2

*TIP*

If the y-intercept is negative, let's say: b = -5  (using slope 8)

the equation will be y = 8x - 5

Hope this helps. I wish you all the best. :)

Heads flipped 240 times, and that's what you're looking for. 240/600

240/600 simplified is 2/5 (0.4)

You're looking for a frequency/percentage so you're looking at the decimal

The table is an illustration of unit rates

Box 2 has the least price per ounce

The given parameters are:

Box 1 = $18.97 per 150 Oz

Box 2 = $11.97 per 100 Oz

Box 3 = $8.97 per 56 Oz

Divide the price by the sizes, to get the rates

[tex]Box 1 = \frac{18.97}{150} =0.126}[/tex]

[tex]Box 2 = \frac{11.97}{100} =0.1197}[/tex]

***Need answer and help to understand Please help I dont understand how to do this Read the two passages and answer the question.Passage 1: "Midas" retold by Thomas Bulfinch[1] Bacchus, on a certain occasion, found his old schoolmaster and foster-father, Silenus, missing. The old man had been drinking, and in that state wandered away, and was found by some peasants, who carried him to their king, Midas. Midas recognized him, and treated him hospitably, entertaining him for ten days and nights with an unceasing round of jollity.[2] On the eleventh day he brought Silenus back, and restored him in safety to his pupil. Whereupon Bacchus offered Midas his choice of a reward, whatever he might wish. He asked that whatever he might touch should be changed into gold. Bacchus consented, though sorry that he had not made a better choice.[3] Midas went his way, rejoicing in his new-acquired power, which he hastened to put to the test. He could scarce believe his eyes when he found a twig of an oak, which he plucked from the branch, become gold in his hand. He took up a stone; it changed to gold. He touched a sod; it did the same. He took up an apple from the tree; you would have thought he had robbed the garden of the Hesperides. His joy knew no bounds, and as soon as he got home, he ordered the servants to set a splendid repast on the table. Then he found to his dismay that whether he touched bread, it hardened in his hand; or put a morsel to his lip, it defied his teeth. He took a glass of wine, but it flowed down his throat like melted gold.[4] In consternation at the unprecedented affliction, he strove to divest himself of his power; he hated the gift he had lately coveted. But all in vain; starvation seemed to await him. He raised his arms, all shining with gold, in prayer to Bacchus, begging to be delivered from his glittering destruction. Bacchus, merciful deity, heard and consented. "Go," said he, "to River Pactolus, trace its fountain-head, there plunge yourself and body in, and wash away your fault and its punishment." He did so, and scarce had he touched the waters before the gold-creating power passed into them, and the river sands became changed into gold, as they remain to this day.Passage 2: "Bacchus's Regret" by Hunter Doyle[1] King Midas returned my beloved teacher to me,so I rewarded him with a wishwhatever he wanted would be.Midas cried, "Give my fingers a golden touch!Then, I shall have a gilded kingdom and such."[5] I tried to make him see the err of his choice,but he would not heed the caution in my voice.I pleaded with Midas, "Be careful what you choose,for you're only thinking of what you'll gainnot what you'll lose."[9] His thirst for wealth became no match for his appetite;after all, a gold apple is not something one can bite.His daughter wept for her poor starving dad,so he wiped her tears and told her not to be sad.[13] Into a golden statue Midas's daughter became,and he and his greedy wish were ultimately to blame.Yet, maybe if I had put up more of a fight and a fret,then I wouldn't have to live with all this regret.Which line from "Bacchus's Regret" summarizes a theme in both passages?
