Answer:
Step-by-step explanation:
Part A
We will use the slope intercept form of the line and then convert later.
Equation
y = mx + b is the general form
Givens
Two data points
(4,180)
(9,325)
Solution
325 = 9x + b
<u>180 = 4x + b</u> Subtract
145 = 5x Divide by 5
145/5 = 5x/5 Do the division
29 = x This represents the cost / day
180 = 4x + b Substitute x = 29 to find b
180 = 4*29 + b Combine
180 = 116 + b Subtract 116 from both sides.
180 - 116 = b
64 = b
Solution for y = mx + b
y = 29x + 64
In Standard form this is
- 29x + y = 64 But the first number must be plus
29x - y = - 64 <<<< Answer A
Part B
y = 29x + 64
f(x) = 29x + 64
Part C
The graph is shown below. Various points are filled in using y = 29x + 64. The y intercept is (0,64) which is labeled. Let x = 1 , 2, 3, 4, ... 10 (which is arbitrary). This may be more easily done on a spreadsheet if you know how to use one to make graphs.
The answer is 540 because 32/48 is 2/3 and 360/540 equals 2/3
Hello!
You need to separate this into two rectangles and add their areas together
first rectangle
3 * 6 = 18
rectangle 2
3 * 2 = 6
18 + 6 = 24
the answer is 24in squared
1.Identify the fractions. Using the distributive property, you’ll eventually turn them into integers.
2.For all fractions, find the lowest common multiple (LCM) -- the smallest number that both denominators can fit neatly into. This will allow you to add fractions.
3.Multiply every term in the equation by the LCM.
4.Isolate variables adding or subtracting like terms on both sides of the equals sign.
5.Combine like terms.
6.Solve the equation and simplify, if needed.
Answer:
So the time is 5:17 a.m.
Explanation:
Note that:
11:32 pm is 28 minutes before midnight.
Adding the 534 hours will take the time into early morning.
So all we need to do to find the new time (am) is to subtract 28 minutes from 534 hours.
534→5 hours and 45 minutes
Subtracting the minutes:
45
28−− ← Subtract
17
So the time is 5:17 a.m.
