A bicycle manufacturing company makes a particular type of bike. Each child bike requires 4 hours to build and 4 hours to test. Each adult bike requires 6 hours to build and 4 hours to test. With the number of workers, the company is able to have up to 120 hours of building time and 100 hours of testing time for a week. If c represents child bikes and a represents adult bikes, can the company build 10 child bikes and 12 adult bikes in a week (1 point) No, because the bike order does not meet the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100 No, because the bike order does not meet the restrictions of 4c + 4a ≤ 120 and 6c + 4a ≤ 100 Yes, because the bike order meets the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100 Yes, because the bike order meets the restrictions of 4c + 4a ≤ 120 and 6c + 4a ≤ 100
Answers
Answer:
A
Step-by-step explanation:
4c + 6a < = 120 ...4(20) + 6(6) = 116 <== correct
4c + 4a < = 100....4(20) + 4(6) = 104 <== incorrect

Please plot this linear equation on a graph, and also explain how to plot it.
[tex]y=3x-7[/tex]
Answers
Answer:
See below:
Step-by-step explanation:
Hello! I hope you are having a nice day.
We can solve this equation in a single step, we just need a bit of theory and a graph.
We can first see that its in [tex]y=mx+b[/tex] form. Which is also known as Slope-Intercept form.
This means that we know the following.
[tex]b[/tex] is the y coordinate of the y intercept.[tex]m[/tex] is the slope of the line.Since we know that, we can see that from our equation that the slope of the line is 3 and the y intercept is (0,-7).
Now that we've gotten that, we can start graphing.
The y intercept is -7 so we can plot (0,-7) as one of our points.
The slope of 3 means that we got up 3 units then right a single unit.
Therefore, another point could be (1,-4).
With our two points, we can create our graph by creating a straight line through those two points and therefore plotting our line.
Cheers!
Answer:
Step-by-step explanation:
y = 3x - 7 is a linear equation with y-intercept -7 (or (0, -7) ) and slope 3. These two quantities are instantly readable from the equation.
There are several ways in which we may graph this equation. One is to plot the y-intercept (0, -7) Then choose an x-value, such as 3, and evaluate the function at that x value. We see that y = 9 - 7, or y = 2, when x = 3. Then another point on the graph besides (0, -7) is (3, 2). Plot (3, 2) and then draw a line through the two plotted points.
Here's another way:
The slope here is 3, or 3/1, which represents rise / run. Plot (0, -7) as before.
Move your pencil from (0, -7) 1 space to the right and 7 spaces up. Then plot a new point at that location. Draw a line through (0, -7) and (1, 0).

Answer:
[tex]\frac{1039}{238}[/tex]
Step-by-step explanation:
7x + 1039 = 245x
Minus the smallest x from the largest.
1039 = 245x - 7x

Answers
Answer:
A proportional relationship between the number of pounds of potatoes (x) and the price in dollars (y) is graphed, and the ordered pair (4, 3) is on the graphed line. Part A: What is the price of 1 pound of potatoes? Show your work, including the proportion you used to determine the price. (8 points) Part B: What does the ordered pair (8, 6) on the graph represent? Explain in words. (2 points)
The point (4,3) means that 4 lbs. of potatoes = $3. Therefore, we have:
4 lbs / $3 = 1lb / x cross-multiply
4x = 3 divide by 4
x = 3/4 dollars = $.75 per pound
The point (8,6) means that 8 lbs. of potatoes = $6.

Answer:
[tex]7\frac{1}{3}[/tex]
Step-by-step explanation:
So for this problem, we want to solve for x
75x + 50 = 600
First, we isolate x by subtracting 50 from both sides.
75x + 50 - 50 = 600 - 50
75x = 550
Then we divide both sides by 75 to find x
75*x/75=550/75

E.
point M
Answers
Answer:
(1.5, 4.5 ) and (- 1.5, - 4.5 )
Step-by-step explanation:
Under a reflection in the x- axis
a point (x, y ) → (x, - y ) , then
(1.5, - 4.5 ) → (1.5, 4.5 )
Under a reflection in the y- axis
a point (x, y ) → (- x, y ) , then
(1.5, - 4.5 ) → (- 1.5, - 4.5 )
If x- axis then y- axis
(1.5, - 4.5 ) → (1.5, 4.5 ) → (- 1.5, 4.5 )

Here's the solution ~
There are total of 193 mimers and each time the elevator can carry 7 miners, now divide the numbers and the remainder ww get gives the number of people left at last, that is also equal to the number of miners in the last trip since they are the last group among them.
[tex] \sf193 \div 7[/tex]On dividing, we get quotient = 27 and remainder as 4
