The equation that represent each situation, in terms of x, is
A = 19 + 0.50xB = 13 + 1.50xThe number of monthly movies watched, x, that would make the two plans have an equal monthly cost is 6 movies.
How to write and solve equation?Let
Monthly cost of plan A = AMonthly cost of plan B = BNumber of monthly movies watched = xPlan A:
A = 19 + 0.50x
Plan B:
B = 13 + 1.50x
Equate A and B
19 + 0.50x = 13 + 1.50x
collect like terms
19 - 13 = 1.50x - 0.50x
6 = x
Hence,
x = 6 movies
In conclusion, the number of monthly movies watched to have an equal amount is 6 movies.

Solve the following equation for b. Be sure to
take into account whether a letter is
capitalized or not.
n³b - tb = 5g
Answer: The correct answer is b=5g/(n^3−t)
Step-by-step explanation:
Solve for b in the following equation
n³b - tb = 5g
First factor out variable b
b(n^3−t)=5g
Divide both sides by n^3-t
b(n^3−t)/n3−t=5g/n^3−t
b=5g/(n^3−t)

Step-by-step explanation:
The expression which represents the function evaluation (f -g)(x) according to the task content is; (f -g)(x) = 2x³ +5x² -8x -4.
Which expression represents (f-g)(x) according to the functions given?
It follows from the task content that the required function evaluation required is; (f -g)(x).
Given;
f(x) = 2x³ +5x² - 6x - 7
g(x)=2x-3
To find;
(f-g)(x).
Since; (f -g)(x) = f(x) - g(x), the resulting expression for (f -g)(x) is;
(f -g)(x) = 2x³ +5x² -6x -7 -2x +3
Collect like terms;
(f -g)(x) = 2x³ +5x² -6x -2x -7 +3
Hence, (f -g)(x) = 2x³ +5x² -8x -4

The best fit line is represented by the equation y = -0.632x + 27.1, where x
represents the total bill in dollars, and y represents the percentage of the
bill left as a tip.
a. What does the best fit line estimate for the percentage of the bill left as
a tip when the bill is $15? Is this reasonable?
b. What does the best fit line predict for the percentage of the bill left as a
tip when the bill is $50? Is this reasonable?
a) The estimate for the percentage of the bill left as a tip with a bill of $15 is of 17.62%, which is reasonable.
b) The estimate for the percentage of the bill left as a tip with a bill of $50 is a non-reasonable -4.5%.
What is the line of best fit?The line of best fit in this problem is defined as follows:
y = -0.632x + 27.1.
In which the variables are defined as follows:
x is the total bill, in dollars.y is the percentage of the total bill left as a tip.Hence, for a bill of $15, the estimate is found replacing x by 15, as follows:
y = -0.632(15) + 27.1 = 17.62%.
Which is reasonable, as it is a positive number.
For a bill of $50, the estimate is obtained as follows:
y = -0.632(50) + 27.1 = -4.5%.
Which is not reasonable, as it is a negative number.

a. Find the bearing from O to A.
b. Find the bearing from O to B.
c. Find the bearing from O to C.
d. Find the bearing from A to O.
Answer:
a. 335°
Step-by-step explanation:
Bearing: The angle (in degrees) measured clockwise from north.
a. The bearing from O to A
Measure the angle from the positive y-axis, clockwise to point A.
Angles on a straight line sum to 180°, so the angle between the negative x-axis and point A is (180° - 115°).
Bearing = 270° + (180° - 115°) = 335°b. The bearing from O to B
Measure the angle from the positive y-axis, clockwise to point B.
Bearing = 270° - 48° = 222°c. The bearing from O to C
Measure the angle from the positive y-axis, clockwise to point C.
Bearing = 180° - 27° = 153°d. The bearing from A to O
Measure the angle clockwise from north of point A to point O.
Bearing = 180° - 25° = 155°Quick easy story and answer one easy question! help wanted 20 points! please i beg of u to help it would mean alot

By how many dollars does the total shipping cost increase if the weight increases by 1 pound?
A rate of change describes how one quantity changes in relation to another quantity. Mathematically, it is defined as the change in one divided by the change in the other quantity.
rate of change = change in total shipping cost / change in weight

Step-by-step explanation:
To find the x intercept, set y =0 and solve for x
7x+7y = -1
y =0
7x+7(0) = -1

If cos of Ф = 2/5, find sin Ф/2 and cos Ф/2. Assume the angles are in the 1st quartile
The exact values of the sine and the cosine of the half angle are √(3 / 10) and √(7 / 10), respectively.
What are the exact values of two trigonometric functions?
Herein we know the exact value of the cosine of an angle set in the first quadrant. Then, the half angle is also in the first quadrant, whose sine and cosine are, respectively:
cos 0.5Ф > 0, sin 0.5Ф > 0
sin 0.5Ф = √[(1 - cos 0.5Ф) / 2]
cos 0.5Ф = √[(1 + cos 0.5Ф) / 2]
First, replace the values of the cosine of the half angle:
sin 0.5Ф = √[(1 - 2 / 5) / 2]
cos 0.5Ф = √[(1 + 2 / 5) / 2]
Second, simplify the resulting expression:
sin 0.5Ф = √[(1 - 2 / 5) / 2]
sin 0.5Ф = √[(3 / 5) / 2]
sin 0.5Ф = √(3 / 10)
cos 0.5Ф = √[(1 + 2 / 5) / 2]
cos 0.5Ф = √[(7 / 5) / 2]
cos 0.5Ф = √(7 / 10)

What is a function?A function y = f(x) is a one to one relationship between two sets X and Y where the set X is called the domain and Y the range of function f(x) ans x ∈ X and y ∈ Y.
As per the given problem a function can be defined as,
c = f(a)
Now, in order to write a linear equation from the given table take any two values of the variables as,
a = 0 and c = 15, a = 4 and c = 8.
Then, the linear equation can be written as follows,
(c - 15)/(a - 0) = (15 - 8)/(0 - 4)
=> c - 15 = -7/4a

A shop makes a profit of £2 750 in March
It has an Easter sale and the profit for April is £3 162.50
Work out the profit percentage increase
The percent increase of the profit is 15%
How to determine the percent increase of the profit?In this question, the figures are given as
Profit in March = £2750
Profit in April = £3162.50
The percentage of the increase of the profit is then calculated using the following equation
Increase percentage = (Profit in April - Profit in March)/Profit in March * 100%
Substitute the known values in the above equation, so, we have the following representation
Increase percentage = (3162.50 - 2750)/2750 * 100%
Evaluate
Increase percentage = 15%
Hence, the increase in percentage is 15%

A formula for 6 gallons of light green paint uses 3/8 gallon of white paint. Liam has 9/16 gallon of white paint. Does Liam have enough white paint to make 8 gallons of light green paint? If not, how much more does he need?
If Liam has 9/16 gallon, he has enough white paint to make 8 gallons of light green paint
What is word problem?A word problem in mathematics is a maths question written as one sentence or more that requires the application of mathematics knowledge to a 'real-life' scenario.
Given that 6 gallons of light green paint use 3/8 gallon of white paint, this can be expressed as:
3/8 gallons of white paint = 6 gallons of light green
We are to determine if 9/16 gallons will be enough to make 8 gallons of light green paint. This can be expressed as
9/16 gallons of white paint = x
Divide both expressions
3/8 x 16/9 = 6/x
2/3 = 6/x
By cross multiplying
2x = 3 x 6
2x = 18
x = 18/2
x = 9
