Please help me I need this question done by tonight. The amount that a consultant charges for her work can be modeled using a linear function. For 4 hours of work, the consultant charges $400. For 5 hours of work, she charges $450. How much money does the consultant earn each hour?

The answer you are looking for is Y = 4X + 14.

To find this, you must solve for B. In doing so, you fill in the equation Y = MX + B, where M = 4, Y = -2, and X = -4. Filling in, you should get -2 = 4(-4) + B, which now you solve for B. Multiply -4 and 4 together to get -16, then add 16 to both sides. This will make B = 14. Finally, fill in Y = MX + B once more, this time only with M and B. Thus making Y = 4X + 14 the answer. Here's a graph to show this is correct.

I hope this helps!

The cost per ounce of the first bottle is $0.415 and the second bottle is $0.699.

The first bottle has the better deal because if you were to have 14 ounces of the first type of shampoo, it would only cost $5.81

Cost per ounce is:

To find the cost per ounce for each bottle, use the formula:

= Total cost / number of ounces

6 ounce bottle:

= 2.49 / 6

= $0.42 per ounce

14 ounce bottle:

= 9.79 / 14

= $0.70 per ounce

The 6 ounce bottle is therefore the better deal.

The measure of angle ∣4 is 250 degrees. The measure of angle ∣A is 67 degrees.

To find the measure of angle ∣4, we can use the fact that angles around a point add up to 360 degrees.

We know that ∣1 is 45 degrees and ∣3 is 65 degrees.

To find ∣4, we can subtract the sum of angles ∣1 and ∣3 from 360 degrees.

Therefore, ∣4 = 360 - (∣1 + ∣3) = 360 - (45 + 65) = 360 - 110 = 250 degrees.

To find the measure of angle ∣A, we can use the fact that the sum of the angles in a triangle is 180 degrees.

We know that ∣B is 90 degrees because it is a right angle.

Therefore, ∣A + ∣B + ∣C = 180 degrees.

Substituting the given values, we get (3x - 8) + 90 + (x - 2) = 180. Simplifying the equation, we get 4x + 80 = 180.

Solving for x, we get x = 25.

Substituting x back into the equation for ∣A, we get ∣A = (3(25) - 8) = 67 degrees.

You found $5, so it's positive. You don't put anything in the negative, because you aren't losing anything.

Answer:

x=900/47, y=720/47

4x=5y == 3600/47 (top and bottom angle values)

3x+3y == 4860/47 (left and right angle values)

If you want the values in mixed number form, reply back.

Step-by-step explanation:

You can set this up in many different ways.

First, the inverse angles are always equal, so 4x=5y

Additionally, 2 sets of angles are supplementary, meaning they add up to 180 degrees; they are 4x+3x+3y=180 and 5y+3x+3y=180; both are equal

You could simplify the above two equations to get 7x+3y=180 and 3x+8y=180, meaning that 7x+3y=3x+8y, and 4x=5y

This simplifies to y=4x/5

Additionally, you could add the equations, meaning that 10x+11y=360, and y=4x/5

This gives you the answer:

x=900/47 and y=720/47.

You could check this by plugging the values into the equation, and if you do the math (which, I know, is kind of painful), you get the supposed values, so hooray!

Answer:

The angles measuring 4x and 5y measure: 3600/47

The other two angles measure: 4860/47

Step-by-step explanation:

The angles measuring 4x and 5y are vertical angles. Vertical angles are congruent, so we have one equation: 4x = 5y.

The angles measuring 5y and 3x + 3y form a linear pair. Angles in a linear pair are supplementary, so their measures add up to 180 degrees. That gives us a second equation: 3x + 3y + 5y = 180, or simply 3x + 8y = 180.

We have a system of two equations in two unknowns, so we can solve for x and y.

4x = 5y

3x + 8y = 180

We will use the substitution method.

Solve the first equation for x: x = 5y/4

Substitute 5y/4 for x in the second equation.

3(5y/4) + 8y = 180

15y/4 + 8y = 180

15y + 32y = 720

47y = 720

y = 720/47

Substitute y with 720/47 in the first original equation and solve for x.

4x = 5y

4x = 5(720/47)

4x = 3600/47

x = 900/47

The angles measuring 4x and 5y measure: 4x = 4(900/47) = 3600/47

The other two angles measure: 3x + 3y = 3(900/47) + 3(720/47) = 2700/47 + 2160/47 =4860/47

i think that you would just take 23/4=$5.75

so take 6 times 5.75 and you should get $34.5

To answer this question, we first need to determine the unit cost (cost per t-shirt).

Step 1: Find the unit cost
Alicia bought 4 T-shirts for a total of $23.00. To calculate the cost per T-shirt (the unit rate), we need to divide the total cost by the number of T-shirts.

So, $23.00 (total cost) divided by 4 (number of T-shirts) equals $5.75. Thus, the unit cost of one T-shirt is $5.75.

Step 2: Calculate the cost for 6 T-shirts
Now that we know the unit cost, we can find out how much 6 T-shirts will cost. To do this, we multiply the unit cost by the number of T-shirts.

So, $5.75 (cost per T-shirt) times 6 (number of T-shirts) equals $34.50.

Therefore, it would cost $34.50 for 6 T-shirts, given the unit rate.

Let x is the days and the y is the height of the plant.

Let the change between x and y is linear.

So, the relation between x and y will take the form ⇒ y = ax + b

where a and b are constants.

At x = 30 ⇒ y = 18  ⇒⇒⇒  ∴ 18 = 30 a + b   → (1)

At x = 90 ⇒ y = 29 ⇒⇒⇒  ∴ 29 = 90 a + b   → (2)

solve (1) and (2) to find a and b

subtract (1) from (2)

∴ 11 = 60 a ⇒⇒⇒ ∴ a = 11/60

substitute at (1) ⇒⇒⇒ ∴ b = 25/2 = 12.5

So, the equation which represents the plants growth is

∴ y = (11/60) x + 12.5

Step-by-step explanation:

Let 1 piece = X

The 2nd piece would be X + 2 feet

Add:

x +x+2 = 26 feet

2x +2 = 26 feet

Subtract 2 from each side:

2x = 24

Divide both sides by 2:

x = 24 / 2

X = 12

One piece is 12 feet the other piece is 14 feet.

Find the x-intercept by substituting in 0 for y and solving for x.

Find the y-intercept by substituting in 0 for x and solving for y.

Let's find the x-intercept first: 2x + (0) = 8

2x = 8

Divide both sides by 2 to isolate and solve for the variable x, or the x-intercept.

x = 4 (x-intercept)

Now find the y-intercept: 2(0) + y = 8

Multiply 2 and 0.

y = 8 (y-intercept)

You have found the x-intercept to be 4 and the y-intercept to be 8. To graph the line, place a point on (4, 0) <== x-intercept and a point on (0, 8) <== y-intercept.

Answer: The statement is [tex]\frac{AD}{DB} +1=\frac{CE}{EB}+1[/tex] and the reason is add 1 both sides.

Explanation:

The given equation is [tex]\frac{AD}{DB} =\frac{CE}{EB}[/tex].

We know that according to the addition property the equation x=y and x+c=y+c are equivalent equations, where c is a constant.

To find the values of x and y in the equation 40 = 12x + 4y, isolate the x term and solve for x, then substitute the value of x into the equation to solve for y.

To find the values of x and y in the equation 40 = 12x + 4y, you need to solve for one variable at a time. First, isolate the x term on one side of the equation by subtracting 4y from both sides:

40 - 4y = 12x

Then, divide both sides by 12 to solve for x:

x = (40 - 4y) / 12

Now you have the equation for x in terms of y. To find the values of y, you can substitute the expression for x into the original equation and solve for y.

The approximate population of South Dakota in 2010 after a 7.9% increase from the 2000 population is 814,477 people.

To find the population of South Dakota in 2010, we need to calculate the increased population based on the given percentage increase. We are provided with a population of 754,844 in 2000 and an increase of 7.9% for 2010.

Here is the step-by-step calculation:

Multiply the population of 2000 by the increase percentage (converted to a decimal):

754,844 x 0.079 = 59,632.68.

Add this increase to the 2000 population to get the 2010 population:

754,844 + 59,632.68 = 814,476.68.

Therefore, the approximate population of South Dakota in 2010 is 814,477 people (rounded to the nearest whole number).

To solve the equation -9/4v + 4/5 = 7/8, subtract 4/5 from both sides, find a common denominator for 7/8 and 4/5, simplify, and multiply by 4/9 to solve for v.

To solve the equation -9/4v + 4/5 = 7/8, we need to isolate the variable v. To do this, we can start by subtracting 4/5 from both sides of the equation, which gives us -9/4v = 7/8 - 4/5. Next, we need to find a common denominator for 7/8 and 4/5. The least common multiple of 8 and 5 is 40, so we can rewrite both fractions with a denominator of 40. This gives us -9/4v = 35/40 - 32/40. Continuing to simplify, we get -9/4v = 3/40. To get rid of the fraction, we can multiply both sides of the equation by 4/9, canceling out the fraction on the left side. This gives us v = (3/40) * (4/9), which simplifies to v = 1/30.
