make a the subject of this formula:
p=n^2+a/n+a
Step-by-step explanation:
we multiply both sides by the denominator on the right to eliminate fraction, so we have..
p*(n+a)= (n²+a/n+a)*n+a
so we have
p(n+a)= n²+a
so opening the bracket on the left hand side we have,
p*n+p*a
pn+pa
so,
pn+pa= n²+a
so collecting like terms we have,
pn-n²= a-pa
so removing a from the equation on the right hand side we have,
pn-n²=a(1-p)
dividing both sides by the equation in the bracket on the right hand side, we have..
pn-n²/(1-p)= a
a = pn-n²/1-p
or
a = n(p-n)/1-p
write in slope form 2y = 24
Answer:
y = 12
Step-by-step explanation:
The equation of the expression is given as;
2y = 24
We are to write in slope form';
In slope form, an equation is expressed as;
y = mx + c
where y and x are the intercept
m is the slope
c is the intercept
Now to write 2y = 24 in intercept form, we have;
2y = 24
divide both sides by 2;
y = 12
Solve the following equation by combining like terms:

Matilda is selling hand-painted vases at a craft fair. She will
have to pay $200 to rent a booth at the fair. The cost of the
paint and other materials to create each vase is $5.50. She is
going to sell each vase for $14.00.
Part 1. Write an inequality to represent the situation in which
Matilda makes a profit. You must define any variable(s) you
use.
Part 2. How many vases must Matilda sell to make a profit?
Explain your reasoning.
Answer:
14x>200+5.5, She must sell 15 or more vases
Step-by-step explanation:
14x>200+5.5
14x>200+5.5
14x>205.5
x>14.68*
She must sell 15 or more vases
*You round up because you cannot sell a partial vase
Answer:
14v > 200 + 5.50v, she will have to sell 24 vases to make a profit
Step-by-step explanation:
It costs $5.50 PER VASE for materials, so you would subtract this from what she sells each vase for. 14 - 5.50 = 8.50. She makes an $8.50 profit per vase sold. We can write 8.50n > 200 to show her profit margin minus the booth fee. If she sold 24 vases, she would be making a profit and this would represent the lowest amount of vases she can sell to make a profit. We can write the inequality 24 ≤ n to show that she can sell 24 vases or more to make a profit.
14n > 200 + 5.50n
336 > 332, true
n > 23

Which piecewise function is shown in the graph?
Answer:
The piecewise function is shown in the graph is
f(x) = -0.5x + 1, x < 0 2x - 2, x ≥ 0 ⇒ AStep-by-step explanation:
At first, you must find the equation of each line
The form of the equation of the line is f(x) = m x + b, where
m is the slope of the line which = Δy/Δxb is the y-intercept which is the y-coordinate of the point of intersection between the line and the y-axisFrom the graph
∵ The line to the left intersects the y-axis at point (0, 1)
∴ b = 1
∵ The line passes through points (0, 1) and (-2, 2)
∴ Δx = -2 - 0 = -2
∴ Δy = 2 - 1 = 1
→ Use them to find the value of m
∵ m = Δy/Δx
∴ m = [tex]\frac{1}{-2}[/tex]
∴ m = -0.5
→ Substitute the values of m and b in the form of the equation above
∴ f(x) = -0.5x + 1
∵ The domain of the function is the values of x
∵ The line starts with an empty circle
→ That means x = 0 does not belong to the domain
∴ The sign of inequality is < without equal
∴ The domain of f(x) is x < 0 ⇒ all values less than 0
∵ We have only one answer has f(x) = -0.5x + 1, x < 0
∴ The graph represents the first answer A
∴ The piecewise function is shown in the graph is
f(x) = -0.5x + 1, x < 0 2x - 2, x ≥ 0Answer:

what calculates the slope of a line from two coordinate points from that line?
Answer:
The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points .
The point-slope form of the equation of the line that passes through (-5, -1) and (10,-7) is
Y+ 7 = -
-- (x-10). What
is the standard form of the equation for this line?

What is the rate of change of y with respect to x for 25x-4y=50
Answer:
The rate of change is y with respect to x is [tex]\frac{25}{4}[/tex]
Step-by-step explanation:
Given
[tex]25x - 4y = 50[/tex]
Required
Determine the rate of change of y w.r.t x
[tex]25x - 4y = 50[/tex]
First, make y subject of formula
[tex]4y = 25x- 50[/tex]
Divide through by 4
[tex]y = \frac{25x}{4} - \frac{50}{4}[/tex]
[tex]y = \frac{25x}{4} - 12.5[/tex]
Next, we differentiate the above w.r.t to x
The result of the differentiation is the solution to the question
[tex]y' = 1 * \frac{25x^{1-1}}{4} -0[/tex]
[tex]y' = 1 * \frac{25x^0}{4}[/tex]
[tex]y' = 1 * \frac{25*1}{4}[/tex]
[tex]y' = \frac{25}{4}[/tex]
Hence, the rate of change is y with respect to x is [tex]\frac{25}{4}[/tex]
By calculating derivative of y with respect to x we got rate of change of y with respect to x for 25x-4y=0 is 25/4
What is derivative?Rate of change of a function with respect to a variable is called derivative of that function with respect to that variable .
Here given relation is 25x-4y=0
[tex]\Rightarrow 4y=25x\\\\\Rightarrow y=\frac{25x}{4}[/tex]
We have to calculate rate of change of y with respect to x so we will calculate derivative of y with respect to x.
we can calculate derivative of y with respect to x as
[tex]\frac{dy}{dx}= \frac{d}{dx} (\frac{25x}{4})\\\\[/tex]
As 25/4 is constant we can take it out from derivative function as it is
[tex]\frac{dy}{dx}= (\frac{25}{4})\frac{dx}{dx}\\\\[/tex]
And we know derivative of a variable with respect to itself is 1
so
[tex]\frac{dy}{dx}= (\frac{25}{4})\times 1\\\\ \frac{dy}{dx}= \frac{25}{4}[/tex]
By calculating derivative of y with respect to x we got rate of change of y with respect to x for 25x-4y=0 is 25/4

A rancher raises five as many cows as horses. If he has 168 cows and horses, how many cows does he have? Complete the equations below, and then use substitution to solve. Let c represent the number of cows and h represent the number of horses Equation 1: c=_h Equation 2: c+h=_
Answer:
There are 28 horses and 140 cows
Step-by-step explanation:
Given
Animals: Cows and Horses
Represent Cows with c and Horses with h
For the first equation, we complete it as thus:
[tex]c = 5h[/tex]
This is so because there are 5 times as many c as h
The second equation will be completed as:
[tex]c + h = 168[/tex]
This is so because the total animals are 168
So, we have:
[tex]c = 5h[/tex]
[tex]c + h = 168[/tex]
Substitute 5h for c in the second equation
[tex]c + h = 168[/tex]
[tex]5h + h = 168[/tex]
[tex]6h= 168[/tex]
Solve for h
[tex]h = 168/6[/tex]
[tex]h = 28[/tex]
Recall that:
[tex]c = 5h[/tex]
[tex]c = 5 * 28[/tex]
[tex]c = 140[/tex]
Hence, there are 28 horses and 140 cows

boris's super metal detector not only helped him win the science fair but also helped him find $6.20 in nickels and dimes yesterday morning. If boris found 14 more dimes than nickels, how many nickels did he find
Answer:
32 Nickels
Step-by-step explanation:
Given
Coins: Nickels (N) and Dimes (D)
$0.05 = 1 nickel and $0.10 = 1 dime
So, the amount implies:
[tex]0.05N + 0.10D = 6.20[/tex]
The number of coin implies:
[tex]D = 14 + N[/tex]
Required
Determine the number of nickels found
Substitute 14 + N for D in [tex]0.05N + 0.10D = 6.20[/tex]
[tex]0.05N + 0.10(14 + N) = 6.20[/tex]
[tex]0.05N + 1.4 + 0.10N = 6.20[/tex]
Collect Like Terms
[tex]0.05N + 0.10N = 6.20 - 1.4[/tex]
[tex]0.15N = 4.8[/tex]
Solve for N
[tex]N = 4.8/0.15[/tex]
[tex]N = 32[/tex]
Hence, he found 32 nickels
