Answer:

x= 7/3

Step-by-step explanation:

y=2x+5

5x-2=2x+5

transfer 2x to the left side and -2 to the right side you get

5x-2x=2+5

as it transfers the sign changes

3x=7

x=7/3

Step-by-step explanation:

Answer:

x^4-3x^3+x^2-4

Step-by-step explanation:

Given the following functions

R(x) = 2x^4 – 3x^3 + 2x – 1 and

C(x) = x^4 – x^2 + 2x + 3

We are to find the profit function P(x)

P(x) = R(x) - C(x)

P(x) = 2x^4 – 3x^3 + 2x – 1 - ( x^4 – x^2 + 2x + 3)

P(x) = 2x^4 – 3x^3 + 2x – 1 - x^4 + x^2 - 2x - 3

Collect the like terms

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

P(x) = x^4-3x^3+x^2+0-4

P(x) = x^4-3x^3+x^2-4

Hence the required profit function P(x) is x^4-3x^3+x^2-4

Answer:

x^4-3x^3+x^2-4

We know that:

Harrison gets $9.50 per hour of work.

He can work a maximum of 15 hours per week.

He needs to earn a minimum of $28.50 per week.

A) We want a function f(h) that tells how much he wins in a week if he works h hours.

So we know that he gets $9.50 per hour of work, then if he works h hours, he gets h times $9.50, then we can just write:

f(h) = $9.50×h

B) First remember that the domain is the set of possible values of h, and the range is the set of possible values of f(h).

We know that the maximum value of h is 15, to find the minimum value of h we need to use the other restriction, that he needs to win at least $28.50, then we need to solve:

$9.50×h = $28.50

h = ($28.50)/($9.50) = 3

Then we can conclude that the domain is:

D = [3, 15]

To find the range, we just need to evaluate the function in the minimum and maximum values of the domain:

f(3) = $28.50

f(15) = $142.50

Then the range is:

R = [$28.50, $142.50]

Step-by-step explanation:

Line segment BC will be an image of side AD using only a translation.

Option 2 is true.

What is Translation?

A transformation that occurs when a figure is moved from one location to another location without changing its size or shape is called translation.

Given that;

A figure ABCD is a square.

Now,

Since, ABCD is a square.

So, All sides of square ABCD are equal to each other.

Since, A translation occurs when a figure is moved from one location to another location without changing its size or shape.

Thus, Line segment BC will be an image of side AD using only a translation.

Therefore, Line segment BC will be an image of side AD using only a translation.

Answer:

Step-by-step explanation:

Part b:  Find the length of the sidewalk.  The walk is the hypotenuse of a right 30-60-90 triangle with horizontal side 2√3.  Using the 30° angle as the reference angle, we get the following from the definition of the cosine function:

cos 30° = adj / hyp, or:

  √3       2√3

 ------- = --------

     2        hyp

This simplifies to

     1          2

 -------- = -------

      2        hyp

Cross multiplying results in:  hyp = 4.  The sidewalk length is 4 miles.

a.  The width of the park can be found using the sine function, the now-known hypotenuse and the 30° angle:

                               1       opposite side

sin 30 degrees = ----- = -------------------------   or 2(opp side) = 4.

                               2                 4

Then the opp side, which is the width of the park, is 2.

The average speed between the times given is 12 m/s

Step-by-step explanation:

Here, we want to calculate rate of change between the times given

Mathematically , we can get the average rate of change using the formula

f(b)-f(a)/b-a

in this case, b = 10 s and a = 5 s

f(b) is d(10) = 0.8(10)^2 = 80

f(a) is d(5) = 0.8(5)^2 = 20

Rate of change is thus;

(80-20)/(10-5) = 60/5 = 12 m/s

Answer: B

Step-by-step explanation: i don't really know but it looks correct

The diagram that models the ratio in the story is diagram A.

When fifi weighs 56 pounds, Buttercup will weigh 8 pounds.

It should be noted that ratio demonstrates how many times one number can fit into another number. It contrast two numbers by ordinarily dividing them. A/B will be the formula if one is comparing one data points.

Let buttercup be x

Let Fifi be 7x

Fifi weighs 56 pounds. This will be:

7x = 56

7x = 56

Divide

x = 56 / 7

x = 8

Buttercup is 8 pounds.

Answer:

m<a=56

m<b=34

m<c=56

Step-by-step explanation:

The rectangle is cut into two triangles. The total of a triangles angles is 180 degrees. The triangles are right triangles which means that the right angle is 90 degrees.

You already have an angle that measures 34 degrees.

Alternate interior angles are congruent. So, the given angle is equal to m<b.

Now add 90+34=124

To get the alternate interior angles (m<a and m<c) subtract 124 from 180 which equals 56 degrees.

Answer:m
