Answer:
B 12.5%
Step-by-step explanation:
The percentage change is calculated as ...
% change = ((new value)/(old value) -1) × 100%
= (36/32 -1) × 100% = 1/8 × 100% = 12.5%

5x-3y=20 line perpendicular
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.⤴⤴⤴

Step-by-step explanation:
Complete the table of values
Answer:
x = 0 —> y = 0 —> ( 0 , 0 )
x = 1 —> y = – 2 —> ( 1 , – 2 )
x = 5 —> y = – 10 —> ( 5 , – 10 )
x = -3 —> y = 6 —> ( -3 , 6 )
Step-by-step explanation:
x = 0 —> y = -2x = -2(0)=0
x = 1 —> y= -2x = -2(1) = -2
x = 5 —> y = -2x = -2(5) = -10
x = -3 —> y = -2x = -2(-3) = 6

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?
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]

9514 1404 393
Answer:
see attached.
Step-by-step explanation:
Your graph demonstrates a possible function, but it has the domain and range swapped.
__
The domain is the horizontal extent, so your line must end at x=-9 on the left and x=6 on the right.
The range is the vertical extent, so the function must extend from -4 at the bottom to +8 at the top.
The attachment shows a linear function with those characteristics.

Use a slash mark ( as the fraction bar if necessary.
Answer:
2/4 or 1/2
Hope this helps!
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.

Paul has

to invest. His intent is to earn

interest on his investment. He can invest part of his money at
6%
and part at
10%
interest. How much does Paul need to invest in each option to make a total of 9%
return on his
$20000
?
6%: ?
10%: ?
Step-by-step explanation:
0,06x + 0,1(20000-x) = 0,09(20000)
0,06x + 2000 - 0,1x = 1800
-0,04x = -200
x = -200 /(-0,04)
x = 5000
therefore,
for 6% interest => total invest =$5000
for 10% interest => total invest = $15000

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
===========================================================
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.
