many adults and children had haircuts on Friday? The
answer is the solution to the following system.
4c + 14a = 588
c+a=42

Answer:
Step-by-step explanatio
it can be 7 children and 1 adult, or 3 adults.
i'd say it's, c = 28, while a = 14
There are 40 adults and 2 children had haircuts on Friday.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
We are given the system of equation as;
x + y = 42
4x + 14y = 568
We need to solve, let 'x' = 42-y and substitute this expression for 'x' in the second equation to get:
4(42-y) + 14y = 568
168 - 4y + 14y = 568
168 + 10y = 568
10y = 400
y = 40
therefore, x = 2
There are 40 adults and 2 children had haircuts on Friday.

Find an equation for the perpendicular bisector of the line segment whose endpoints
(5,-4) and (-9, -8).
are
Answers
Answer:
The equation for the perpendicular bisector of the line segment will be:
[tex]y=-\frac{7}{2}x-13[/tex]
Step-by-step explanation:
Given the endpoints of the line segments
(5,-4)(-9, -8)Determining the slope between (5,-4) and (-9, -8)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(5,\:-4\right),\:\left(x_2,\:y_2\right)=\left(-9,\:-8\right)[/tex]
[tex]m=\frac{-8-\left(-4\right)}{-9-5}[/tex]
[tex]m=\frac{2}{7}[/tex]
We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:
slope = m = 2/7
Thus, the slope of the the new perpendicular line = – 1/m = (-1)/(2/7)= -7/2
Next, determining the mid-point between (5,-4) and (-9, -8)
[tex]\mathrm{Midpoint\:of\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\quad \left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]
[tex]\left(x_1,\:y_1\right)=\left(5,\:-4\right),\:\left(x_2,\:y_2\right)=\left(-9,\:-8\right)[/tex]
[tex]=\left(\frac{-9+5}{2},\:\frac{-8-4}{2}\right)[/tex]
Refine
[tex]=\left(-2,\:-6\right)[/tex]
We know that the point-slope form of equation of line is
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where
m is the slope of the line(x₁, y₁) is the pointsubstituting the slope of the perpendicular line -7/2 and the point (-2, -6)
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-\left(-6\right)=-\frac{7}{2}\left(x-\left(-2\right)\right)[/tex]
[tex]y+6=-\frac{7}{2}\left(x+2\right)[/tex]
Subtract 6 from both sides
[tex]y+6-6=-\frac{7}{2}\left(x+2\right)-6[/tex]
[tex]y=-\frac{7}{2}x-13[/tex]
Therefore, the equation for the perpendicular bisector of the line segment will be:
[tex]y=-\frac{7}{2}x-13[/tex]
The difference of two numbers is 7, and their sum is 49. Find the two numbers.
Answers
Answer:
x= 28 and y=21
Step-by-step explanation:
x - y = 7
x + y = 49
add the two equation and the y's will cancel out
2x = 56 divide by 2
x = 28
replace 28 for x in the first equation and solve for y
28 - y = 7
y = 21

A school ordered 3 large boxes of board markers. After giving 15 markers to each of 3 teachers, there were 90 markers left. How many markers were originally in the box?
Answers
Step-by-step explanation:
Initially, the school had 3 boxes of board markers, and each box had X board markers, where X is the number we want to find.
Then the initial number of board markers is 3*X.
We know that after giving 15 markers to 3 teachers, we have other 90 markers left. This can be written as:
total markers = markers for the teachers + markers left
3*X = 15*3 + 90 = 45 + 90 = 135
now, we divide both sides by 3.
X = 135/3 = 45
From this, we know that in each box we have 45 markers

-12(x-7)= -133
Answers
Answer:
The number is 31
Step-by-step explanation:
Let the number be x
Subtract 12 from the number = x - 12
Then multiply the difference by -7 = (-7)*(x - 12)
(-7)(x - 12) = -133
-7x - 12*(-7) = -133
-7x + 84 = - 133
-7x = -133 - 84
-7x = -217
x = -217/-7
x = 31

Max plans to build two side-by-side identical rectangular pens for his pigs that
will enclose a total area of 216 square feet. What is the minimum length of
fencing he will need? What are the dimensions of the total enclosure?
Answers
Answer:
864
Step-by-step explanation:
216 + 216 = 432 +216= 448 +216= 864
The minimum length of fencing is 72ft and dimensions are x = 18ft, y=12ft
What is fencing?A fence, wall is a vertical construction used to barricade a space from views, air, or light or to keep out people and animals.
This excludes buildings or parts of buildings that are intended to support a roof, awning, or other horizontal structure, such a building's wall.
let x be the length of each side and y be the width of each side of fence
xy = 216
y = 216/x
total length of fencing = 2x+3y
P = 2x+3y
P = 2x + 3(216/x)
P = 2x + 648/x
On differentiating
P' = 2 - 648/(x²)
for P' = 0
2 = 648/(x²)
(x²) = 324
x = 18
y = 216/18
y = 12ft
Hence length of fencing is = 2x+3y
= 2*18 + 3(216/18)
= 2*18 + 3*12
= 72ft

What is the equation of the sinusoid shown in the graph?
A. y=3cos(pi/2x)
B. y=3cos(4x)
C. y=cos(4x)
D. y=3cos(1/4x)
Answers
Answer:
Answer: C
Step-by-step explanation:
The Cosine Function
The graph of a cosine function is a sinusoid that starts at its maximum value of 1 at x=0 and takes x=2π radians to complete a full cycle. The function of the parent cosine function is:
[tex]y=\cos x[/tex]
Both the amplitude A and the angular frequency w of a cosine can be modeled by the function
[tex]y=A\cos(\omega x)[/tex]
The graph of the cosine function shown in the figure has an amplitude of A=3 and it completes a full cycle at x=π/2, thus:
[tex]\frac{\pi}{2}\omega =2\pi[/tex]
Thus:
[tex]\omega = 4[/tex]
Therefore, the equation of the sinusoid is:
[tex]y=3\cos (4x)[/tex]

This means for every 4 gallons, there are 64 cups. If you divide 64 by 4 you get 16.
Now you know for every 1 gallon, there are 16 cups.
Multiply 16 by 3 so you can figure out how many cups there will be for every 3 gallons.
The answer is 48 cups. For every 3 gallons, there will be 48 cups.
Answer:
48 cups
Step-by-step explanation:
There are 16 cups in 1 gallon. I know this because i divided 64 by 4 to get the amount added. If you subtract 16 from 64, you get 48 cups.
