solve the system of equations
−4x+3y=−2
y=x−1

x =
y =

Answers

Answer: x = -1 and y = -2

Step-by-step explanation:

So if you know y = x-1 you can plug that in where y is in the first equation

-4x + 3(x-1) = -2

Distribute the 3:

-4x +3x -3 = -2

Combine like terms:
-x -3 = -2

Add 3 to both sides:
-x = 1

Multiply by -1:
X = -1

Then you plug that into the other equation to get y=(-1)-1

Which is -2

To make MP3 players, a cost estimator determined it costs a company $1500 per week for
overhead and $45 for each MP3. Determine an equation that represents the company's
total cost c.

Answers

Let x be the number of MP3 players the company produces per week.

If c is the total cost of the company per week, then

c = 45x + 1500

Cost =45x#of MP3’s +1500
This equation is if you’re trying to find the total cost of 1 week

What is the length of the Midsegment?
12
18
6
9

Answers

Answer:

The length of Midsegment = 9

Step-by-step explanation:

the midsegment connecting the midpoints of two sides of a triangle is parallel to the third side of the triangle, and the length of this midsegment is half the length of the third side.

According to the Midsegment Theorem:

The midsegment connects the midpoints of two sides of a triangle is parallel to the third side of the triangle.The length of this midsegment is half the length of the third side.

Thus,

The midsegment (x+4) is half the length of the third side (4x-2). so

[tex]\left(x+4\right)\:=\:\frac{1}{2}\:\left(4x\:-\:2\right)[/tex]

[tex]x+4=2x-1[/tex]

Subtract 4 from both sides

[tex]x+4-4=2x-1-4[/tex]

[tex]x=2x-5[/tex]

Subtract 2x from both sides

[tex]x-2x=2x-5-2x[/tex]

Simplify

[tex]-x=-5[/tex]

divide both sides by -1

[tex]\frac{-x}{-1}=\frac{-5}{-1}[/tex]

Simplify

[tex]x=5[/tex]

The length of Midsegment = x+4

= (5) + 4 ∵ x = 5

= 9

Therefore, the length of Midsegment = 9

Addition property of equality

Answers

Answer:

[tex]k = -4[/tex]

Step-by-step explanation:

Given

[tex]\frac{3}{2} = k + \frac{11}{2}[/tex]

Required

Solve for k

[tex]\frac{3}{2} = k + \frac{11}{2}[/tex]

Apply subtraction property

[tex]\frac{3}{2} - \frac{11}{2} = k + \frac{11}{2} - \frac{11}{2}[/tex]

Apply addition property

[tex]\frac{3}{2} +(- \frac{11}{2}) = k + \frac{11}{2} +(- \frac{11}{2} )[/tex]

The fractions on the right represent an additive inverse.

So, we have:

[tex]\frac{3}{2} +(- \frac{11}{2}) = k[/tex]

Take LCM

[tex]\frac{3+(-11)}{2} = k[/tex]

Remove bracket

[tex]\frac{3-11}{2} = k[/tex]

[tex]\frac{-8}{2} = k[/tex]

[tex]-\frac{8}{2} = k[/tex]

[tex]-4 = k[/tex]

[tex]k = -4[/tex]
