Mathematics

kumpel [21]3 years ago

Answer: Here are all of the answers to the best of my ability :)

1: Solve the following equation for “y”:

3y - 4x = 15

Steps:

1. Add 4x to both sides. 3y = 4x + 15

2. Divide both sides by 3. Y= 4/3x + 5

Final answer: y= 4/3x + 5

————————————————————-

2. Write an equation in slope intercept form for a line that passes through the y axis at 5 and has a slope of -3.

Slope intercept form: y = mx + b

B= y intercept

Mx= slope

Equation: y = 3x + 5

———————————————————————————————————

3. Is (-2, 6) a solution of -3y + 5y = 4x?

Steps:

1. -3(6) + 5(6) = 4x

2. -18y + 30y = 4x

3. 12 = 4x

4. Rewrite the equation: 4x = 12

5. Divide by 4 on both sides

6. x = 3

Yes, this is a solution to -3y + 5y = 4x

————————————————————————-

4. Write the following equation in slope intercept form: x + 8y = 30

1. Add negative 8y to both sides. X = -8y + 30

Answer: x= -8y + 30

——————————————————————————-

5. Graph this equation: 2x + 5y = 20

That’s all I could find. Sorry if I made I mistake. Have a good day!

Joe is responsible for reserving hotel rooms for a company trip. His company changes plans and increases how many people are goi
AURORKA [14]

Answer:

<h2>He is going to pay 40*900= $36000 for the reservation</h2>

Step-by-step explanation:

Step one:

We are told that they need at least 50 total rooms.

Joe has paid for 16 rooms since Joe can only reserve rooms in block, and a block has 8 rooms, then Joe has paid for 2 blocks.

There is a deficit of 50-16= 34rooms

Required

The Number of blocks Joe need to reserve in addition is 34/8

=4.25

The blocks can not be in decimal, so we need to approximate, which is 5 blocks

Therefore Joe is going to reserve 5*8= 40 rooms

<u>He is going to pay 40*900= $36000 for the reservation</u>
