if you shift the linear parent function, f(x)=x, up 13 units, what is the equation of the new function?

Answer:

maybe

[tex] y = \frac{1}{2} x + 0.5[/tex]

Answer:

x - 2y = - 1

Step-by-step explanation:

The equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

Obtain the equation in slope- intercept form

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 3, - 1) and (x₂, y₂ ) = (3, 2) ← 2 points on the line

m = [tex]\frac{2+1}{3+3}[/tex] = [tex]\frac{3}{6}[/tex] = [tex]\frac{1}{2}[/tex]

y = [tex]\frac{1}{2}[/tex] x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (3, 2), then

2 = [tex]\frac{3}{2}[/tex] + c ⇒ c = [tex]\frac{1}{2}[/tex]

y = [tex]\frac{1}{2}[/tex] x + [tex]\frac{1}{2}[/tex] ← in slope- intercept form

Multiply all terms by 2

2y = x + 1 ( subtract 2y from both sides )

0 = x - 2y + 1 ( subtract 1 from both sides )

- 1 = x - 2y , that is

x - 2y = - 1 ← in standard form

Answer:

Step-by-step explanation:

To create a system of equations, write an equation to model each condition that must be satisfied in the given situation.

It is given that x represents the width of the flower bed and that y represents the area of the base of the birdbath.

Write an equation to represent the condition regarding the planting area in the flower bed. It is given that there is 35 square feet of planting area. The flower bed is 3 feet longer than the width.

x(x+3) - y = 35

Write an equation to represent the condition regarding the cost of the soil and the birdbath. The question gives that the soil will cost $5 per square foot and the birdbath will cost $18 per square foot of the base.

5x(x+3)+18y=150

Combining both of the equations gives the following system of equations.

x(x+3)-y=35

5x(x+3)+18y=150

Answer:

5.6

Step-by-step explanation:

If there is 70 percent of chocolate milk in the fridge and she holds 0.125 in each canister and divide and get 5.6 then turn that back into a fraction which should be easy.

Ana can fill exactly 5 full glasses of chocolate milk with her 7/10 of a liter, as each glass holds 1/8 of a liter. The calculation involves simple fraction division and the realization that 56/10 simplifies to 5 3/5, indicating the number of full glasses.

The question is about determining how many glasses of chocolate milk Ana can fill from the amount she has in her refrigerator. Since each glass holds 1/8 of a liter and Ana has 7/10 of a liter of chocolate milk, we need to calculate how many 1/8 liter portions make up 7/10 of a liter. To find this, we can set up a division:

[tex]\(\frac{7/10}{1/8}\)[/tex].

To divide fractions, we multiply by the reciprocal of the divisor:

[tex]\(\frac{7/10}{1} \times \frac{8}{1}\) = \(\frac{56}{10}\).[/tex]

Now we simplify the resulting fraction:

[tex]\(\frac{56}{10}\)[/tex] simplifies to [tex]\(5 \frac{3}{5}\)[/tex].

So, Ana can fill 5 full glasses of chocolate milk and will have some milk left over.

The equations are as follows where x represents the number of minutes the cell phone is used.

For plan one: Total cost = $20 + $0.15x

For plan two: Total cost = $35 + $0.10x

For both the costs to be the same, we need to use the cell phone for

300 minutes.

Equations are relations showing the value of one quantity related to another quantity when it can change. The changing value is the variable.

We are informed that one cell phone plan charges $20 per month plus $0.15 per minute used. A second cell phone plan charges $35 per month plus $0.10 per minute used.

We are asked to write and solve an equation to find the number of minutes you must talk to have the same cost for both calling plans.

Let the number of minutes the cell phone is used be x minutes.

Now we solve for equations for both plans in the following way:-

Plan one:

Charges $20 per month plus $0.15 per minute used.

When the use is for x minutes, the additional charge = $0.15*x = $0.15x

∴ Total cost = Fixed cost + Additional cost

or, Total cost = $20 + $0.15x.

Plan two:

Charges $35 per month plus $0.10 per minute used.

When the use is for x minutes, the additional charge = $0.10*x = $0.10x

∴ Total cost = Fixed cost + Additional cost

or, Total cost = $35 + $0.10x.

We are asked to find the number of minutes used so that the costs in both the plans are equal. To find this we equate the equation of total costs in both the cases to get:

$20 + $0.15x = $35 + $0.10x.

Subtracting ($20 + $0.10x) from both sides of the equation, we get

$20 + $0.15x - ($20 + $0.10x) = $35 + $0.10x - ($20 + $0.10x).

or, $20 + $0.15x - $20 - $0.10x = $35 + $0.10x - $20 - $0.10x.

or, $0.05x = $15

Dividing both sides of the equation by $0.05, we get

$0.05x/$0.05 = $10/$0.05

or, x = 300.

∴ We must talk for 300 minutes for both the plans to cost the same to us.

Answer:

4309

Step-by-step explanation:

initial 8000

1st year 8000(1-.06)=8000(.94)

2nd year 8000(.94)^2

...

10 year 8000(.94)^10 approx 4309

Check the picture below.

bearing in mind that ⌈some expression⌉ means "ceil" or the ceil() function, which means any number in between one integer and the next, "ceils" or gets bumped up to the next integer.

namely for example, for y = ⌈x⌉ will yield

y(0.5) = 1

y(0.7) = 1

y(0.0000001) = 1

y(3.0000001) = 4

y(-2.000001) = -2

y(-5.00001) = -5

and so on

the same is true btw for the y = ⌊x⌋ or the "floor" floor() function, but it "floors" or drops down instead.

y(0.5) = 0

y(3.9999999) = 3

y(-5.0000001) = -6

and so on.

in this case is y = 4⌈x⌉, so any values in between each integer for "x" gets bumped up.

Answer:

-1

Step-by-step explanation:

Your answer is the first option, "One is a factor of every whole number since every number is divisible by itself".

This is true because whenever you multiply 1 by anything you always get the thing you multiplied by, which makes it a factor of every number.

You can also find this by eliminating the other options, for example a prime number is any number whose factors are 1 and itself, 2 factors, so since 1 only has 1 factor it is not prime and option 3 is eliminated.

This also eliminates option 4 because 1 cannot be a composite number if it only has 1 factor.

I hope this helps!

The true statement among the given options is that one is a factor of every whole number since every number is divisible by itself.

A prime number is that number that is only fully divisible by 1 and that number itself.

Since we know that every number is divisible by 1. Thus 1 is also a factor of every number.

Thus one is a factor of every number.

Answer:

c = 2s + 3

Step-by-step explanation:

Let c be Carly's age.

Carly is 3 more . . . than twice her sister's age.

We can translate "twice her sister's age" into 2s.

Carly is 3 more than 2s.

We can translate this into:

Carly is 3 + 2s.

c = 2s + 3

Carly's age, given that it's three more than twice her sister's age, can be expressed with the mathematical expression 2s + 3. This translates the stated relationship into an algebraic context.

The question is asking for an expression that represents Carly's age in relation to her sister's age. Given that Carly's age is three more than twice the age of her sister, we can express Carly's age (C) as 2s + 3, where s is her sister's age.
