If varies directly as y and y = 15 when = 25. If = 155 then y is​

Answers

Answer 1

Answer:

y = 93

Step-by-step explanation:

I assume the other variable is x.

"If x varies directly as y and y = 15 when x = 25. If x = 155 then y is​"

Direct variation:

x = ky

25 = k * 15

k = 25/15

k = 5/3

The direct variation equation is

x = (5/3)y

155 = (5/3)y

y = 155 * 3/5

y = 93

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.⤴⤴⤴

Paul has
$20000
to invest. His intent is to earn
9%
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%: ?

Answers

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

Answers

Answer:   A.  18

===========================================================

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.

Draw a possible function that satisfy the given domain and range

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.
