Answer:

y=5/2x-14

Step-by-step explanation:

Lines parallel to each other have the same slope this means you can take out the third and fourth answers.  With the given slope you can solve for the equation of the line that goes through (-6, -29).  Do this by plugging in (-6, -29) as x and y values and plugging in 5/2 as the slope.  

(-29)=5/2(-6)+b, Solve for b

-29=-15+b

-14=b, The equation of the line is y=5/2x-14

Answer:

y = 2½x - 14

Step-by-step explanation:

Remember, "parallel" in Geometry and Algebra means that they have SIMILAR <em>rate of changes </em>[<em>slopes</em>]. This is how your work should look:

-29 = 5⁄2[-6] + b

+15 -15

+15

------------------

-14 = b

Here is your parallel equation:

y = 2½x - 14 [5⁄2 = 2½]

F(x)=(x-4)(x+2) i need help
Westkost [7]

Answer:

x^2 - 2x - 8

Step by step explanation:

Distribute the x as well as the -4  

x * x = x^2

x * 2 = 2x

-4 * x = -4x

-4 * 2 = -8

Combine all the like terms, which means terms with the same variable or regular integers must be either added or subtracted amongst each other.

2x + -4x = -2x

The final answer after combining all the like terms is

x^2 - 2x - 8

What type of angle is
mash [69]

Answer:

I'm really sorry I can't tell you the answer because you have to measure the angle by yourself using a protractor. But I gave you information about types of angles if you got the degree of angles ( e.g 90 degrees). Hope it helped.

Step-by-step explanation:

acute angle-an angle between 0 and 90 degrees  

right angle-an 90 degree angle  

obtuse angle-an angle between 90 and 180 degrees  

straight angle-a 180 degree angle

The cost in dollars of making x items is given by the function C(x)=10x+900 .
Stella [2.4K]

For the given cost equation we have:

a) Fixed cost is $900.

b) For making 25 items the cost is $1150.

c) D: x ∈ [0, 150]

   R: c ∈ [900, 2400]

<h3>Working with the cost equation.</h3>

Here we know that the cost equation is:

c(x) = 10*x + 900.

First, we want to get the fixed cost, it is given by evaluating the function in x = 0.

c(0) = 10*0 + 900 = 900

The fixed cost is 900.

b) Now we want to get the cost for making 25 items, to get this, we just evaluate in x = 25.

c(25) = 10*25 + 900 = 250 + 900 = 1150

c) Now, if the maximum cost is 2400, then the maximum number of items that we can make is x₀, such that:

c( x₀) = 2400 = 10*x₀ + 900

Solving for x₀ we get:

x₀ = (2400 - 900)/10 = 150

Now we want to get the range and domain.

We know that we can make between 0 and 150 items, so the domain is:

D: x ∈ [0, 150]

For the range, we know that the fixed cost for 0 items is 900, and the maximum cost is 2400, then the range is:

R: c ∈ [900, 2400]
