Answer:

C.) 2 units to the right, 5 units up

Step-by-step explanation:

The graph shifts left or right when a number modifies the "x" value before it is affected by any other number/function in the equation. This number is within parentheses with the "x". Subtracting a value moves the function to the right, whereas adding a value moves the function to the left. Therefore, since 2 is being subtracted from "x", the function has been shifted 2 units to the right.

The graph shifts up or down when the y-intercept changes. The y-intercept is the "b" value in a standard function. You can identify this value by plugging in zero to "x". If this number is positive, the function is shifted upwards, and if this number is negative, the function is shifted downwards. Therefore, since there is a 5 added to the equation, the function is shifted 5 units up.

An equation is formed of two equal expressions. Juliet teaches softball for 5.5 hours, while she teaches football for 12.5 hours.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

A.) Let the amount of time spent on soccer be represented by y, while the amount of time spent on softball is represented by x. Therefore, we can write,

x+y=18

y=2x+1.5

Hence, the system of equations to model the situation is x+y=18 and y=2x+1.5.

B.) Substitute the value of y from the second equation in the first equation, therefore,

x+y=18

x+2x+1.5=18

3x = 16.5

x = 5.5 hours

Substitute the value of x in the second equation, we will get,

y=2x+1.5

y=2(5.5)+1.5

y=11+1.5

y=12.5 hours

Hence, Juliet teaches softball for 5.5 hours, while she teaches football for 12.5 hours.

The objective function of the printing company in a bid to minimize cost is; p = 25x + 20y.

The objective function in a linear programming problem is the real-valued function whose value is to be either minimized or maximized dependent on the constraints defined on the given linear programming problem over the set of feasible solutions. The objective function of a LPP is a linear function of the form z = ax + by in which case, z is the parameter to be optimised.

It therefore follows from the complete question that the objective function is; p = 25x + 20y. This follows from the fact that Supplier X charges $25 per case. Supplier Y charges $20 per case and the parameter to be optimised is price.

Remarks;

The complete question is as follows;

A printing company orders paper from two different suppliers. Supplier X charges $25 per case. Supplier Y charges $20 per case. The company needs to order at least 45 cases per day to meet demand and can order no more than 30 cases from Supplier X. The company needs no more than 2 times as many cases from Supplier Y as from Supplier X. Let x = the number of cases from Supplier X and y = the number of cases from Supplier Y.

Step-by-step explanation:

Since the straw is 6 inches long, the approximate length of the cylinder's radius is 3.32 in

To find the radius of the cylinder, we need to apply Pythagoras' theorem.

Pythagoras' theorem states that in any right-angled triangle, the square of the hypotenuse side equals the sum of the squares of the other two sides.

Mathematically, c² = a² + b² where

Now, since the 6 inch straw inclined at an angle forms a right angle with the radius,r and length of the cylinder, h.

Since the length of the straw is the hypotenuse side, L we have that

L² = h² + r²

Making r the radius of the cylinder subject of the formula, we have

r = √(L² - h²)

Given that

Substituting the values of the variables into the equation,we have

r = √(L² - h²)

r = √(6² - 5²)

r = √(36 - 25)

r = √11

r = 3.316 in

r ≅ 3.32 in

So, the approximate length of the cylinder's radius is 3.32 in

Answer:

The value of the stock can be found by: x × 1.26.

Step-by-step explanation:

The value of the stock in year one can be found by multiplying x by 1.4. This will represent a 40% increase in value. The following year, the stock decreases in value by 10%; this is represented by multiplication by 0.9. For example, if the value of the stock was $5:

5 × 1.4 = 7                    (A 40% increase in value)

(5 × 1.4) * 0.90 = 6.3   (A further 10% decrease in value)

Rather than writing out the long version, we can simplfify by multiplying 1.4 by 0.9 to get 1.26 .We can also replace 5 with x to get a more general equation.

The equation 11x + 10y = 32 is a linear equation, and the solution to the linear equation 11x + 10y = 32 is [tex]y = \frac{32 - 11x}{10}[/tex]

The equation is given as:

11x + 10y = 32

Subtract 11x from both sides

10y = 32 - 11x

Divide both sides by 10

[tex]y = \frac{32 - 11x}{10}[/tex]

Hence, the solution to the linear equation 11x + 10y = 32 is [tex]y = \frac{32 - 11x}{10}[/tex]

Answer:

The answer is 13, 9 and (-1)

Step-by-step explanation:

For x = (-2)

h(x) = (-2x + 9)

h(-2) = [-2(-2) + 9]

h(-2) = (4 + 9)

h(-2) = 13

For x = 0

h(x) = (-2x + 9)

h(0) = [-2(0) + 9]

h(0) = (0 + 9)

h(0) = 9

For x = 5

h(x) = (-2x + 9)

h(5) = [-2(5) + 9]

h(5) = [(-10) + 9]

h(5) = (-1)

Thus, The answer is 13, 9 and (-1) when x = (-2), 0 and 5 respectively.

Hi Student!

In the problem statement we are given a number of 0.38 meters which it then tells us to write and solve an equation to convert that to centimeters.  The first step would be to write an equation that would perfectly incapsulate what we are trying to do.

[tex]x = meters\ *\ \frac{100\ centimeters}{1\ meter}[/tex]

This equation can now be used for any amount of meters where we can input the amount of meters that we have and that will cancel with the meters on the bottom while multiplying by 100 to which we then will receive our value of x in centimeters.  Let's solve the equation using 0.38 meters.

Input the values

Cancel the meters

Simplify the expression

Therefore, our final answer is that 0.38 meters can be converted to centimeters which would then get 38 cm as the result.

Step-by-step explanation:theres only 2 sides on a coin

Answer: 50% , as likely as not .

Step-by-step explanation:

The probability of a 2 on the die is 1/6. The probability of a heads on the coin is 1/2. That means that (on average) half the time you roll a 2 you'll also get heads and the other half you'll get tails. What's half of 1/6?

The possibilities are:

1H 2H 3H 4H 5H 6H

1T 2T 3T 4T 5T 6T

So, it's 1/12 that you'll get a 2 and heads (on average).

The volume of cylinder is 2352π in³ while the volume of cone is 784π in³. The volume of the cylinder is three times the volume of the cone

An equation is an expression that shows the relationship between two or more numbers and variables.

A cylinder has radius 14 inches and height 12 inches. A cone has the same radius and height.

Volume of cylinder = π * radius² * height = π * 14² * 12 = 2352π in³

Volume of cone = (1/3) * π * radius² * height = (1/3) * π * 14² * 12 = 784π in³
