Which graph can be used to find the solution of the following system of equations?
Answer:
A
Step-by-step explanation:
1. Honestly, my course of action, if allowed to, would be to use my graphing calculator. Obviously, you can graph the first equation but the second one requires some rearranging, keeping in mind that we are isolating the y.
[tex]2y-2x=10[/tex]
[tex]2y=2x+10[/tex]
[tex]y=x+5[/tex]
So now we have an equation of the line. Simply enter both of these equations into your graphing calculator and you're all set.
I hope this helps!

The width of a rectangle is 1/4 its length. The perimeter of the rectangle is 375 ft. What is the length, in feet, of the rectangle?
Answer:
Required Answer:-Let
[tex]\sf length=x [/tex]
[tex]\sf Breadth={\dfrac {x}{4}}[/tex]
As we know that in a rectangle
[tex]{\boxed{\sf Perimeter=2 (l+b)}}[/tex]
Substitute the values[tex]{:}\longrightarrow\sf 2 \left (x+{\dfrac {x}{4}}\right)=375 [/tex]
[tex]{:}\longrightarrow\sf 2 \left({\dfrac {4x+x}{4}}\right)=375 [/tex]
[tex]{:}\longrightarrow\sf 2 \left({\dfrac {5x}{4}}\right)=375 [/tex]
[tex]{:}\longrightarrow\sf {\dfrac {10x}{4}}=375 [/tex]
[tex]{:}\longrightarrow\sf 10x=4×375 [/tex]
[tex]{:}\longrightarrow\sf 10x=1500 [/tex]
[tex]{:}\longrightarrow\sf x={\dfrac {1500}{10}}[/tex]
[tex]{:}\longrightarrow\sf x=150[/tex]
[tex]\therefore[/tex]Length =150feet

A water slide starts at (0,144) and ends at (12,0) what is the slope of the slide
Answer:
-12
Step-by-step explanation:
The slope of a line is just the difference of y-values divided by the difference of x-values
[tex]m = \frac{y_2-y_1}{x_2-x_1} = \frac{144-0}{0-12} = \frac{144}{-12} = -12[/tex]

ABC is a central angke in a cirvle with center B. The length of the radius is 13 km and m
Answer:
[tex]\frac{1170pi}{360m}[/tex]km
Step-by-step explanation:
To find the length of the minor arc, you find the circumference of the circle multiplied by the arc angle, which is [tex]\frac{45}{m}[/tex] over 360 degrees.
Circumference of the circle with center B = 13×2×pi
= 26pi
Length of minor arc = 26pi × [tex]\frac{45}{m}[/tex] ×[tex]\frac{1}{360}[/tex]
= [tex]\frac{1170pi}{360m}[/tex]km

Answer:
X-intercept- ( 3/7,0)
Y-intercept- (0,-3)
Step-by-step explanation:
To find the y-intercept(s), substitute in 0 for x and slove for y
y=7(0)-3
simplify y=-3
to find the x-intercept(s), substitute in 0 for y and slove for X
0=7x-3
rewrite equation- 7x-3=0 and slove
which would equal 3/7
All the fudge machines at a chocolate factory work at the same rate. Six machines working simultaneously can complete a big order in 22 hours. How many hours would it take to fill the order if the number of working machines decreased by factor of 4?
Answer:
88 hours
Step-by-step explanation:
Since we are decreasing the number of machines by a factor of four and all the machines work at the same rate, we are simply going to increase the work hours by a factor of 4
Increasing the work hours by a factor of 4 will yield 22 * 4 = 88 hours
So it will take 88 hours to fill the order if the number of machines is deceased by a factor of 4

Answer:
Company B offers the lowest price per pound of 12.72
Step-by-step explanation:
Unit Price
Given a product that costs X dollars and has Y pounds, the unit price is given by X/Y dollars per pound.
Elle is comparing prices to purchase candy online. Company A offers 2 1/2 pounds of chocolate for $32.50 and Company B offers 2 3/4 pounds of chocolate for $35.00.
The offer of Company A is for 2 1/2 pounds = 2.5 pounds
The offer of Company B is for 2 3/4 pounds = 2.75 pounds
The unit price for Company A is $32,50/2.5 = $13/pound
The unit price for Company B is $35,00/2.75 = $12.72/pound
Company B offers the lowest price per pound of 12.72

A unicorn daycare center requires there to be 2 supervisors for every 18 baby unicorns. Write an equation that shows the relationship between nnn, the number of supervisors, and uuu, the number of baby unicorns. Please note that this is a magical daycare center, so fractional supervisors are allowed.
Answer:
n = (1/9)u
Step-by-step explanation:
This is a direct variation relationship of the form
n = ku
For n = 2, u = 18.
2 = k * 18
We solve for k.
k = 2/18
k = 1/9
Now we use k in the equation of the relationship.
n = (1/9)u

After taking 4 pieces of fruit out of a bag, 12 pieces of fruit remained. How
many pieces of fruit were in the bag to start?
A. f: 4 = 12
B. 12 - 4 = f
C. 12 : f= 4
D. f-4 = 12
E. 4 + f = 12
F. 12 + f = 4
Answer:
D. f-4=12
Step-by-step explanation:
total fruits (f)
took 4
12 remained
taken + remainder = initial total
4 + 12 = f
f = 12 -4
230% of what number is 92
Answer:
250
Step-by-step explanation:
Following shows the steps on how to derive this formula
Step 1: If 92% of a number is 230, then what is 100% of that number? Setup the equation.
230
92% = Y
100%
Step 2: Solve for Y
Using cross multiplication of two fractions, we get
92Y = 230 x 100
92Y = 23000
Y = 23000
100 = 250
What is
230
% of
92
? = 250
Answer:
250
Explanation:
230 x 100 ÷ 92 =250

Step-by-step explanation:
(x − 4)(x^2 − 5x − 6) = x(x^2 − 5x − 6) -4(x^2 − 5x − 6)
= x^3 -5x^2 -6x -4x^2 +20x +24
= x^3 +x^2(-5-4) +x(-6+20) +24
= x^3 − 9x^2 + 14x + 24 . . . . matches the first choice

Find the value of f(-7).
Answer:
f(-7) = -4
Step-by-step explanation:
We want to find the value of the function when x = -7
The y value of the function when x= -7 is -4
f(-7) = -4
Answer:
f(-7)=-4
Step-by-step explanation:
If you look at the x, in this case -7, and follow it down to where it stops on the parabola, you will see that it's y value is -4.
