y varies jointly as x and z. If y = 12 when x = 4 and z = 3, find y when x = 9 and z = 8.

Answers

Answer:

y = 72

Step-by-step explanation:

Given y varies jointly as x and z then the equation relating them is

y = kxz ← k is the constant of variation

To find k use the condition y = 12 when x = 4 and z = 3

12 = k × 4 × 3 = 12k ( divide both sides by 12 )

1 = k

y = xz ← equation of variation

When x = 9 and z = 8 , then

y = 9 × 8 = 72

During May, Andy had cash inflows of $550, $40, $65, and $80. He had cash outflows of $10, $30, $60, $25, $100, and $250. What is Andy’s net cash flow?

PLEASE HELP ME I DON'T KNOW WHAT THE ANSWER IS

Answers

Answer:

positive 260

Step-by-step explanation:

add the cash inflows

550+40+65+80 = 735

add the outflows

10+30+60+25+100+250 = 475

then substract the outflows from the inflows

735-475 = 260

So Andy's net cash flow is positive 260

Please consider marking this answer as brainliest if it helped you. Thanks!

Andy’s net cash flow is $260.

Given that, during May, Andy had cash inflows of $550, $40, $65, and $80.

What is subtraction?

Subtraction is the process of taking away a number from another. It is a primary arithmetic operation that is denoted by a subtraction symbol (-) and is the method of calculating the difference between two numbers.

Total cash inflow

= 550+40+65+80

= $735

Total cash outflow

= 10+30+60+25+100+250

= $475

So, net cash flow =735-475

= $260

Therefore, Andy’s net cash flow is $260.

Determine the slope of the line represented by the equation 9x + 4y = 8. Represent the slope in decimal form.

Answers

Answer:

slope = - 2.25

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

9x + 4y = 8 ( subtract 9x from both sides )

4y = - 9x + 8 ( divide through by 4 )

y = - 2.25x+ 2 ← in slope- intercept form

with slope m = - 2.25

#CarryOnLearning

[tex]MysteriousNature[/tex]

Answer:

k = 0

Step - By - Step:

1. 3 - k - 5k = 3

3 - 6k =3

2. rearrange terms:

3 - 6k = 3

-6k + 3 = 3

3. Subtract  3 from both sides of the equation:

-6k_3=3

-6k+3-3=3-3

4. simplify:

-6k + 3 - 3 = 3 - 3

-6k = 3 - 3

-6k = 0

5. divide both sides of the equation by the same term:

-6k = 0

-6k/-6 = 0/-6

6. simplify:

k = 0/-6

The value of an autographed baseball card increased from $39 to $65.
What is the percent increase in value of the baseball card? Round to the nearest hundredth of a percent.

Answers

Answer: The percent of increase is 66.67%.

Step-by-step explanation:

Find the percent of increase of baseball cards.

Step 1: Subtract the starting value from the final value.

                                       65 - 39 = 26

Step 2: Take the value you get and divide it by the starting value.

                                       26 ÷ 39 = 0.666667

Step 3: Multiply what you get by 100.

                                       0.666667 × 100 = 66.6667

Step 4: Round what you get the nearest hundredth of a percent.

                                        66.6667 → 66.67%

For what values of x and y are the two triangles congruent by HL?

Answers

Answer:

y = 4 and x = 11

Step-by-step explanation:

x = y + 7                  Substitute the first equation into the second equation and

                               solve for y

x + 1 = 3y

y + 7 + 1 = 3y

8 = 2y

4 =   y                      x = y + 7

                               x = 4 + 7

                                 x = 11

Answers

Answer:

D) 39

Step-by-step explanation:

There are a couple of steps to this. First, note that you must plug in the given number that replaces x into the right side's x. After you find the answers, you must then subtract both answers to get your result.

First step, find g(8):

g(x) = 3x - 2

When x = 8,

g(8) = 3(8) - 2

Remember to follow PEMDAS, the order of operations. First, multiply, then subtract:

g(8) = (3 * 8) - 2

g(8) = (24) - 2

g(8) = 22

Next step, find g(-5):

g(x) = 3x - 2

g(-5) = 3(-5) - 2

g(-5) = (3 * -5) - 2

g(-5) = (-15) - 2

g(-5) = -17

Note that you are subtracting both numbers. When there are two negative signs directly next to each other, it becomes a positive:

22 - (-17) = 22 + 17 = 39

D) 39 is your answer.
