please help, i would really appreciate it

1.

Write an equation for the line. Use slope-intercept form, if possible.

Through (-6, 5) and (-2, 8)

2.

Use the Gauss-Jordan method to solve the system of equations.

4x - y - 2z = -12

7x - 6z = -17

7y + z = 60

3.

Solve the problem.

A company makes 3 types of cable. Cable A requires 3 black wires, 3 white wires, and 2 red wires. Cable B requires 1 black, 2 white, and 1 red. Cable C requires 2 black, 1 white, and 2 red. If 100 black wires, 110 white wires, and 80 red wires were used, then how many of each cable were made

2 math problems, probablility and linear math...MAT117..tough

Solve the system of equations by using the inverse of the coefficient matrix.

2x - 4y = -2

3x + 4y = -23

and this problem:

Solve the system of equations by using the inverse of the coefficient matrix.

x - y + 2z = -4

3x + z = -1

x + 3y + z = 5

Solve the problem.

A recording company is to release 30 new CDs in the categories of rock, country, jazz, and classical. If twice the number of rock CDs is to equal three times the number of country CDs and if the number of jazz CDs is to equal the number of classical CDs, how can the CDs be distributed among the four types? (Let x be the number of rock CDs, y the number of country CDs, z the number of jazz CDs, and w the number of classical CDs. Let w be the parameter.)

1. Write the augmented matrix for the system. Do not solve.

-2x + 9z = 2

-2y + 9z = 22

3x + 5y - 2z = 10

2. Use the Gauss-Jordan method to solve the system of equations.

6x - 5y = 4

-6x + 5y = -2

3. Use the Gauss-Jordan method to solve the system of equations.

x - y + 3z = 2

4x + z = 2

x + 4y + z = 18

Solve the problem.

Ten students in a graduate program were randomly selected. Their grade point averages (GPAs) when they entered the program were between 3.5 and 4.0. The following data were obtained regarding their GPAs on entering the program versus their current GPAs. Use the equation of the least squares line to predict the current GPA of a student whose entering GPA is 2.8.

Entering GPA (x) Current GPA(y)

3.5 3.6

3.8 3.7

3.6 3.9

3.6 3.6

3.5 3.9

3.9 3.8

4.0 3.7

3.9 3.9

3.5 3.8

3.7 4.0

Find the equation of the least squares line.

Two separate tests are designed to measure a student's ability to solve problems. Several students are randomly selected to take both tests and the results are shown below.

here is the problem: man, I cannot do this one either!

Regrind, Inc. regrinds used typewriter platens. The cost per platen is $1.50 The cost to regrind 60 platens is $600 Find the linear cost function to regrind platens. If reground platens sell for each, how many must be reground and sold to break even?

yes, another HARD math problem!! Thank you in advance..Its great to know someone can help!

In deciding whether or not to set up a new manufacturing plant, analysts for a popcorn company have decided that a linear function is a reasonable estimation for the total cost C(x) in dollars to produce x bags of microwave popcorn. They estimate the cost to produce 10,000 bags as $5480 and the cost to produce 15,000 bags as $7780 . Find the marginal cost of the bags of microwave popcorn to be produced in this plant.

So here is my math problem, I just cant figure these types out...I am struggling hard!!! THANK YOU in advance..I appreciate it!!

Write a cost function for the problem. Assume that the relationship is linear.

A cab company charges a base rate of $2.00 plus 20 cents per minute. Let C(x) be the cost in dollars of using the cab for x minutes.

alright, here is my math problem, its algebra..linear math

The mathematical model C(x)= 400x + 70,000 represents the cost in dollars a company has in manufacturing x items during a month. Based on this, how much does it cost to produce 900 items?
