Rhoda is asked to graph this system of equations: 5x - 6y = 4 3y + 2x = 7 How many times will the lines intersect? O A. The lines will intersect infinitely many times, because they are identical. O B. The lines will not intersect, because this system has no solutions. O C. The lines will intersect once, because this system has one solution. D. There is no way to tell without graphing the lines first.
Answer:
C. The lines will intersect once, because this system has one solutionStep-by-step explanation:
System of equations:
5x - 6y = 4 3y + 2x = 7The system of linear equations has one solution if the lines intersect, no solution if the lines are parallel, infinitely many solutions if lines are same
Let's put the lines into slope-intercept form to compare
Line1
5x - 6y = 46y = 5x - 4y = 5/6x - 4/6Line 2
3y + 2x = 73y = -2x + 7y = -2/3x + 7/3As we see lines have different slopes so they are different and they intersect once
This system has one solution
Answer:
C. The lines will intersect once, because this system has one solution

10. A person walks 12.0 m east, then turns and goes 5.00 m west, then turns and goes back 2.00 m east.
a) What is the person's distance?
b) What is the person's displacement?
Step-by-step explanation:
Given that,
A person walks 12.0 m east, then turns and goes 5.00 m west, then turns and goes back 2.00 m east.
(a) Distance is equal to total path covered during the entire journey.
Distance = 12 + 5 +2
Distance = 19 m
(b) The shortest path covered is equal to the shortest path traveled. Let east is positive and west is negative. So,
Displacement = 12 +(-5) +2
Displacement = 9 m

Manuel runs a 100-meter race. 6 seconds after the race started Manuel is 40 meters from the starting line and reaches his max speed; he runs at this max speed for the rest of the race. Manuel notices that he is 75 meters from the starting line 11 seconds after the race started.
Suppose Manuel runs for an additional z seconds after reaching his max speed...
What is Manuel's distance from the starting line 6+z seconds after the race started?
What is Manuel's distance from the starting line x seconds after the race started (provided x≥6x)?
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
40 metres covered in 6 seconds
Max speed attained after 6seconds
75 meters covered after 11 seconds
Average Speed for first 40 meters :
Speed = distance / time
Speed = 40m / 6s
Speed = 6.67m/s
To obtain the maximum speed :
Next (75 - 40) meters = 35 meters was covered in (11 - 6)seconds = 5 seconds
Speed at this point is maximum :
Hence, maximum speed = (35m / 5s) = 7m/s
Suppose, Manuel runs for an additional z seconds after reaching max speed :
Distance from starting line 6+z seconds after race started?
Distance after 6 seconds = 40 metres
Distance after z seconds = 7 * z
Total distance = (40 + 7z)
What is Manuel's distance from the starting line x seconds after the race started (provided x≥6x)?
Distance for first 6 seconds = 40 meters + distance covered after 6 seconds = (7 * (x-6))
40 + 7(x - 6)

In order to convert this equation to Slope-Intercept Form, you must first isolate y.
What is the first step in isolating y?
3x+2y=4
Use Division Property of Equality to divide the equation by 3.
Use Addition Property of Equality to add 2y to both sides of the equation.
Use the Subtraction Property of Equality to subtract 3x from both sides of the equation.
Use Subtraction Property of Equality to subtract 4 from both sides of the equation.
Answer:
use the subtraction property of equality to subtract 3x from both sides of the equation
Step-by-step explanation:
y is on the left so move everything else to the right side
According to the Subtraction Property, both sides of an equation remain equal following a subtracting of the same amount from both sides of the equation
The first step in isolating y in the equation 3·x + 2·y = 4 is the option;
Use the Subtraction Property of Equality to Subtract 3·x from both sides of the equationReason:
The slope and intercept form of the straight line equation is the the equation in the form y = m·x + c
Where;
m = The slope of the equation
c = The y-intercept
The given equation is 3·x + 2·y = 4
To isolate y, the terms containing y, are placed on one side of the equation, while the other terms are placed on the other side as follows;
First step; 3·x + 2·y - 3·x = 4 - 3·x (Subtraction property of equality)
Second step; 2·y = 4 - 3·x
Third step; [tex]\dfrac{2 \cdot y}{2} = \dfrac{4 - 3 \cdot x}{2}[/tex] → y = 2 - 1.5·x (Division property of equality)
y = 2 - 1.5·x = -1.5·x - 2
y = -1.5·x - 2 Equation in slope and intercept form
Therefore, the first step is use the Subtraction Property of Equality to Subtract 3·x from both sides of the equation

Let the graph of g be a translation 3 units up, followed by a vertical stretch by a factor of 2 and a reflection in the x-
Axis of the graph of
f(x) =3x^2-3x write a rule for g
G(x) =
15 points!!!!
Answer:
The answer is [tex]g(x)= -6x(x-1)+3[/tex]
Step-by-step explanation:
we know that f(x) is written as [tex]3x^{2}-3x[/tex]
to show that the graph is being translated up, vertically stretching, and reflecting across the x axis, we need to factor the function.
[tex]f(x)= 3x^{2}-3x \\ 3x(x-1)\\[/tex]
now we can incorporate the changes to this graph.
multiply 3x by 2 and -1. (2 for a stretch and -1 for a reflection).
[tex]-6x(x-1)[/tex]
tack on the +3 to show a translation of 3 units up.
[tex]-6x(x-1)+3[/tex]
therefore, [tex]g(x)= -6x(x-1)+3[/tex]
hope this helps!
The rule for the graph of g after all transformations of the function f(x) = 3x² -3x is;
g(x) = 6x² + 3x + 6
The graph of f(x) is given as;
f(x) =3x^2-3x
According to the parameters given;
First, the graph of g is a translation 3 units up, therefore, we have;
g(x) = f(x) + 3g(x) = 3x² - 3x + 3Secondly, followed by a vertical stretch by a factor of 2 and a reflection in the x axis.
This means that the graph must be multiplied by 2 and x values containing x be now regarded as -x
g(x) = 6x² - 3x + 6And a reflection in the x-axis yields;
g(x) = 6(-x)² -3(-x) + 6g(x) = 6x² + 3x + 6Ultimately, the rule for the graph of g is;
g(x) = 6x² + 3x + 6.

Chic-ken Rulez is a food vendor at the state fair that only sells complete box meals which includes a sandwich (chicken or turkey), fries, and drink. Customers walk up to the counter at Chic-ken Rulez and place an order.The counter employee enters the order into the system which is displayed on several screens for all other employees to see the items that need to be made. In the kitchen sandwich makers assemble the selected sandwich once it displays on the order screen. The fry master will cook, salt, and scoop the ordered fries into a cup. Meanwhile, the employee that took the order, will prepare the requested drink. Once the sandwich and fries are complete, they are place in a window where the counter employee places all items in a box and delivers it to the customer. Taking the order and entering it into the system takes 5 minutes. Once entered, the display screens instantly show the items to be made. The counter employee then takes an average of 3 minutes to make a drink. On average, it takes sandwich makers 8 minutes to complete a sandwich and place in the pick-up window. The fry maker takes 12 minutes on average to complete a cup of fries and place in the pick-up window. It takes the counter employee 10 minutes to box all items and hand to customer for delivery. All times listed are flow times for each activity and include the effects of waiting.1) Draw a process map/flowchart for the above process and Label it Process #1Chic-ken Rulez wishes to improve the process by reducing the time to deliver a meal box. Customers often make an order and leave the counter area to find seating. This is the root cause for delivery times being so long because on average a customer's meal order is called 3 times before it is actually picked up which completes delivery.To reduce the process time, Chic-ken Rulez is going to provide customers with a miniature plastic chicken with a GPS tracker inside at the time of the order. The order process is the same except now the box and delivery activity will be two separate activities. Delivery is now performed by food runners that use a handheld device to locate the GPS plastic chickens, collect the plastic chicken for re-use, and deliver a customer’s ordered meal box.It now takes 2 minutes to box a meal. Based on preliminary tests, the average time to locate a GPS plastic chicken and deliver a meal box in the food area takes 7 minutes.2) Draw a process map/flowchart for the above modified process and Label it Process #2
