What is the slope-intercept form of the following equation?
2x+2y=20
Question 2 options:
y= x+10
2y= -2x+20
y= -x-10
y= -x+10
Answers
Answer:
[tex]y=-x+10[/tex]
Step-by-step explanation:
First we must know the format of slope-intercept form!
This is: [tex]y=mx+b[/tex] (where "m" is the slope and b is the y-intercept)
Given this equation: [tex]2x+2y=20[/tex] we must convert this into the format of slope-intercept form.
First, we should move the "2x" to the other side of the equation, we do this by subtracting -2x from 2x and proceed to move it to the other side.
This would be result in: [tex]2y=-2x+20[/tex]
Next, we need to isolate the "y" variable by dividing the 2 off of it.
What you do to one side you do to the other!
-2 / 2 is -1 so this will just be "-x"
20 / 2 is 10
Therefore, our resulting equation will be: [tex]y = -x+10[/tex]
I hope this helped! Feel free to ask questions if you feel the need!

The length of a rectangle is 7 feet less than four times with width. The Perimeter of the
rectangle is 146 feet. Find the length and width of the rectangle. ( P = 2L +2W)
Answers
Answer:
Step-by-step explanation:
p = 2L+ 2W
length
(7-4)
3 feet
p = 2L+ 2W
146 = 2*3 + 2* w
146 = 6 + 2w
146-6 = 6-6 +2w
140 = 0+ 2w
140 = 2w
70 feet = w
width is 70 feet
p= 2L+2W
146 = 2*a +2* 70
146 = 2a + 140
146-140 = 2a + 140-140
6 = 2a
3 feet = a
length is 3 feet
width is 70 feet.

De enero a junio, 46200 inmigrantes solicitaron la ciudadanía. Durante este mismo período el año pasado, se postularon 120000 inmigrantes. ¿Cuál es el porcentaje de disminución?
Answers
Usando el concepto de porcentaje, se encuentra que el porcentaje de disminución es de 61.5%.
El porcentage de disminución es la disminución multiplicada por 100% y dividida por la cantidad inicial.
Disminución de 120000 imigrantes para 46200 imigrantes, entonces:
[tex]P = \frac{(120000 - 46200)}{120000} \times 100\% = 61.5\%[/tex]

5x-3y=20 line perpendicular
Answers
Answer:
y=(-3/5)x
Step-by-step explanation:
5x-3y=20
-3y=-5x+20
y=(5/3)x-(20/3)
perpendicular lines have opposite reciprocal slopes
Answer:
Perpendicular line is y = -3/5 x - 20/3
Step-by-step explanation:
First subtract 5x to move it to the other side. Now you have -3y = -5x + 20 . Next divide -3 on both sides to get y by its self. Now you have
y = 5/3 x - 20/3.
To find the perpendicular line, just remember that slope will be opposite. Look at the graph, I did for you above.⤴⤴⤴

Given A and B, use your knowledge of sets to determine which one of the following numbers is not in
AUB.
A = {-10, 8, 12, 26, 29}
B = {-8, - 1,5, 26, 36}
A.18
B. -10
C. 26
D. 36
E. None of the above
Answers
===========================================================
Explanation:
The set A U B represents the list of items that are either in set A, set B or both sets at the same time. The "U" is the union symbol.
Set A U B looks like this
A U B = {-10, 8, 12, 26, 29, -8, - 1,5, 26, 36}
I basically started with set A, then tacked on the stuff in set B shown in bold.
From here, we toss out the duplicate item 26 and we can optionally sort the set
A U B = {-10, -8, -1, 5, 8, 12, 26, 29, 36}
We see that the number 18 is not in this final set, which is why choice A is the answer.
--------------------
Put another way: the number 18 is neither in set A nor set B, so it cannot be in set A U B.
Something like -10 is in set A, so it's going to be in set A U B as well. We can rule out choice B for this reason. Choices C and D follow a similar idea as choice B.

please help me get my grade up by answering this question I'll mark brainliest whoever answers first!<3
Answers
Answer:
24:8
Step-by-step explanation:
Given the following data;
Batch = eggs + sticks of butter
4 batches = 12:4
8 batches = 2 * 4 batches
Therefore, 8 batches = 2*(12:4)
8 batches = 24:8
Hence, the equivalent ratio Sierra would use if she wants to make 8 batches is 24 eggs to 8 sticks of butter.

The slope of the line that passes through (-2, -3) and (2, -1) will be 1/2.
What is the slope?The slope is the ratio of rising or falling and running. The difference between the ordinate is called rise or fall and the difference between the abscissa is called run.
The slope of the line is given as,
m = (y₂ - y₁) / (x₂ - x₁)
From the graph, the points are (-2, -3) and (2, -1). Then the slope of the line is calculated as,
m = (- 3 + 1) / (-2 - 2)
m = 2/4
m = 1/2
The slope of the line that passes through (-2, -3) and (2, -1) will be 1/2.
