Vlad spent 20 minutes on his history homework and then completely solved x math problems that each took 2 minutes to complete. What is the equation that can be used to find the value of y, the total time that Vlad spent on his homework, and what are the constraints on the values of x and y?
y=2x+20; x is any integer greater than or equal to 0, and y is an integer greater than or equal to 20.
y=2x+20; x is any real number greater than or equal to 0, and y is any real number greater than or equal to 20.
y=20x+2; x is any integer greater than or equal to 0, and y is an integer greater than or equal to 20.
y=20x +2; x is any real number greater than or equal to 0, and y is any real number greater than or equal to 20.
Answer:
The answer is A. y = 2x + 20; x is any integer greater than or equal to, 0 and y is any integer greater than or equal to 20

Which functions are linear Select all that applies A) s=4r - 2 B) s=r + 10 C) s= 9r - 7 D) s=6r + 6
Step-by-step explanation:
The graph of linear function is a straight line.
General form of the linear function is -
y = a + bx
where a is the y -intercept and b is the slope.
Both a and b are constants.
Here,
x is independent variable whereas y is dependent variable.
For example -
y = 2x + 15
Rapid Rental Car charges a $55 rental fee, $20 for gas, and $0.65 per mile driven. For the same car, Capital Cars charges $55 for rental and gas and $0.75 per mile.
Answer:
200 miles
Step-by-step explanation:
Given data
Rapid Rental Car
charges a $55 rental fee
$20 for gas, and
$0.65 per mile driven
let the number of miles be x, the total charges y
y=55+20+0.65x
y= 75+0.65x----------1
Capital Cars
charges $55 for rental and gas and
$0.75 per mile.
let the number of miles be x, the total charges y
y=55+0.75x
y= 55+0.75x----------2
Required
The number of miles driven before the two Rental companies charge the same amount
equate 1 and 2
75+0.65x= 55+0.75x
collect like terms
75-55= 0.75x-0.65x
20= 0.1x
x= 20/0.1
x= 200miles
Hence the distance will be 200 miles for the charges to be the same

Y = 1/2x + 3 on a graph
Answer:
Step-by-step explanation:
What is the question? If you want to know how to graph this equation, it's usually easiest to start with the intercepts, i.e., the points where the line crosses the axes.
y = ½x + 3 tells you that the line crosses the y-axis at (0,3), so plot that point.
Then let y = 0 and solve for x.
0 = ½x + 3
x = 6
The line crosses the x-axis at (6,0), so plot that point as well.
Then draw the line passing through those two points.
A new Playstation game system costs $380. The tax on the system is 4%. What is the total cost of the system including tax? *
Answer:
395.2
Step-by-step explanation:
380 x 0.04 = 15.2
380 + 15.2 = 395.2
Answer:
The cost of the system including the tax is $395.20.
Step-by-step explanation:
If the tax is 4% that means that the total price will equal...
380 + (380)(0.04) = $395.20
Therefore the cost of the system including the tax will be $395.20.

find the length of the bold arc. Round your answer to the nearest tenth.
Answer:
62.83 m
Step-by-step explanation:
Given that,
The radius of the circle, r = 15 cm
Major angle = 240°
We need to find the length of the bold arc. The formula used to find the arc length is given by :
[tex]l=\dfrac{\theta}{360}\times 2\pi r\\\\=\dfrac{240}{360}\times 2\pi \times 15\\\\=62.83\ m[/tex]
So, the length of the bold arc is equal to 62.83 m.
Solve. A standard coffee mug has a capacity of 16 fluid ounces. If Annie needs to fill 6 mugs with coffee, how many total quarts of coffee does she need?
Answer: 3 quarts of coffee.
Step-by-step explanation:
A coffee mug can take 16 fluid ounces.
Annie needs to fill up 6 mugs so the total ounces needed for 6 mugs would be:
= 16 * 6
= 96 fluid ounces
As the answer needs to be in quarts, convert the above.
1 quart = 32 fluid ounces
96 fluid ounces = 96/32
= 3 quarts
