Answer:

The Distributive Property is used, which consists of multiplying the factor by each of the addends.

2x (x-4) = 2x.x-2x.4 = 2 x 2 -8x

It is better to understand what you are doing. Hope this can help you :)

Answer:

slope: $\frac{3}{4}$ ; y-intercept: 1

Step-by-step explanation:

First, you must rearrange the function into y = mx + b form:

2x + x = 4(y - 1)

Simplify both sides:

3x = 4y - 4

Subtract 3x and 4y from both sides:

-4y = -3x - 4

Divide both sides by -4:

y = $\frac{3}{4} x$ + 1

Now that it is in y = mx + b form, you can find the slope and y-intercept. In y = mx + b form, m is the slope and b is the y-intercept. Therefore:

m = $\frac{3}{4}$ = slope

b = 1 = y-intercept

Answer:

so, i have a method of multiplying fractions, but im not going to strait give you the answer

Step-by-step explanation:

multiply the whole number (1) by the denominator (3) and then add it to the numerator (1).

you multiply the fractions from there.

this is a very fun way of doing fraction multiplying with mixed numbers!

have a good day! :D

An aircraft factory manufactures airplane engines. The unit cost (the cost in dollars to make each airplane engine) depends on t

Juliette [100K]

Answer:

Minimum unit cost = 5,858

Step-by-step explanation:

Given the function : C(x)=x^2−520x+73458

To find the minimum unit cost :

Take the derivative of C(x) with respect to x

dC/dx = 2x - 520

Set = 0

2x - 520

2x = 520

x = 260

To minimize unit cost, 260 engines must be produced

Hence, minimum unit cost will be :

C(x)=x^2−520x+73458

Put x = 260

C(260) = 260^2−520(260) + 73458

= 5,858

How might a change in the environment affect plants differently than it would animals?

valentina_108 [34]

Answer:

Some plants need certain things in their environment, so if their environment changes it could make the plants not grow. Animals would most likely either move to a different area or would get used to the change.

A parachutist descends 40 feet in 4 seconds. What integer represents the parachutist's change in height in feet per second?

polet [3.4K]

Answer:

-10

Step-by-step explanation:

You want to know the rate of descent in feet per second represented by a descent of 40 feet in 4 seconds.

The rate is the amount divided by the time:

-40 ft/(4 s) = -10 ft/s

The relevant integer is -10.

Saira is using the formula for the area of a circle to determine the value of .

klio [65]

For this problem, we just have to use the values we're given to calculate the approximate value of pi.

The formula presented is

$\pi=Ar^{-2}$

When you have a negative exponent, we can use the following property

$a^{-b}=\frac{1}{a^b}$

Using this property, our problem turns out to be

$\pi=\frac{A}{r^2}$

Now, we just need to plug the given values on this equation

$\pi=\frac{50.265}{4^2}=3.1415625\approx3.142$

The approximated value for pi is 3.142.
