Answer:
B. 1.95x + 2.50 = 27.46; Isaac traveled 12.8 miles.
Step-by-step explanation:
If x represents the number of miles driven by the taxi
Then, amount charged= $ (2.50+1.95x)
Isaac was charged $27.46
2.50+1.95x = 27.46
Subtracting both sides by 2.50, we get
1.95x= 24.96
Dividing both sides by 1.95, we get
x=12.8
The linear equation will be 1.95x + 2.50 = 27.46
Amount charged to pick up passenger = $2.50 to pick up a passenger
Amount charged per mile = $1.95 per mile
Since Isaac was charged $27.46, then the equation will be:
2.50 + 1.95(x) = 27.46
2.50 + 1.95x = 27.46
Therefore, the linear equation will be 1.95x + 2.50 = 27.46

Show your work
Answer:
it isn't obvious from your problem statement where the missing numbers are in your table. We have assumed that Barbara charges the same hourly rate for all mowing jobs, so the red numbers were the ones that were missing.
Since we know our times-8 and times-9 times tables, all the work is mental. There is nothing to show. Each number in the Dollars column is 8 times the number in the Hours column.
B) See the table on the right. Again, we know our times tables. 5*9 = 45, and so on.
C) 45 -40 = 5
Barbara earns 5 dollars more at the theme park for 5 hours' work than she does mowing lawns. (Check: The rate difference is $1 per hour, so the difference in earnings will be $5 for 5 hours.)

In the morning a group of hikers hiked 3 ½ miles, took a break, and then hiked another 2 ¾ miles. The group then stopped for lunch. In the afternoon, the group the hiked 4 ¼ miles, and took another break. How many more miles do they need if the whole trail is 14 miles long?
Answer:
3 2/4
Step-by-step explanation:
1/2 is equivalent to 2/4 so you add 3 2/4 + 2 3/4 and that = 6 1/4 and its simple math from there on, 6 1/4 + 4 1/4 = 10 2/4 finally 14 - 10 2/4 = 3 2/4

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
In the morning a group of hikers hiked 3 ½ miles
and then hiked another 2 ¾ miles. then group the hiked 4 ¼ miles.
Total miles to cover = 14 miles
So, number of miles to be driven
= 14 - ( 3 ½ + 2 ¾ + 4 ¼)
= 14 - ( 7/2 + 11/4 + 17/4)
= 14- (14/4 + 11/4 + 17/4)
= 64 - 42 / 4
= 22/4= 11/2
= 5.5 miles
Hence, 5.5 miles are left to cover.

A movie production company was interested in the relationship between the budget to make a movie and how well that movie was received by the public. The company collected information on several movies and used it to obtain the regression equation y = 0.145x+0.136, where x represents the budget of the movie (in millions of dollars) and y is the predicted score of that movie (in points from 0 to 1). Which statement best describes the meaning of the y-intercept of the regression line?
When the score of a movie is 0 points, the predicted budget is $0.
When the score of a movie is 0 points, the predicted budget is $0.136 million.
When the budget of a movie is $0, the predicted rating is 0.136 points. This interpretation is not meaningful, because a movie cannot have a budget of $0.
When the budget of a movie is $0, the predicted rating is 0.145 points. This interpretation is not meaningful, because a movie cannot have a budget of $0.
Answer:
Pretty sure it's (C), although I am unable to check. --> IT IS C I GOT 100%
"When the budget of a movie is $0, the predicted rating is 0.136 points. This interpretation is not meaningful, because a movie cannot have a budget of $0."
The y intercept is the starting "points", which is .136. Basically the company uses the equation to figure out how much money they got from a movie and how it increases as the budget increases. They make money off points.
So when there's no budget or a budget less than a million, thats what they earn in points.
Which is, .136 ; this means when theres no budget, they are expected to start with .136 points. (Probably cuz they're a cool company or something)
========================
If you're looking for a question that asks "What is the predicted score of a movie that has a $5 million budget?", its (C), .861
If you're looking for a question that asks "What is the predicted score of a movie that has a $250,000 budget?", it's (B) 0.17225 points
[THIS PART IS SEPARATE FROM THE ORIGINAL QUESTION]
========================
ED2021
The interpretation of a given situation is required.
When the budget of a movie is $0, the predicted rating is 0.136 points. This interpretation is not meaningful, because a movie cannot have a budget of $0.
The regression equation is
[tex]y=0.145x+0.136[/tex]
where,
[tex]y[/tex] = Predicted score of that movie
[tex]x[/tex] = Budget of movie in millions of dollars
The y intercept is the value of the function when [tex]x=0[/tex]. So,
[tex]y=0.145\times 0+0.136\\\Rightarrow y=0.136[/tex]
When [tex]x=0[/tex] this means the budget of the movie is 0 million dollars.
This is not meaningful.
So, the correct interpretation of the y intercept is When the budget of a movie is $0, the predicted rating is 0.136 points. This interpretation is not meaningful, because a movie cannot have a budget of $0.

What is the equation of the line that passes through the points (-6,-7) and (6,3)
Answer:
[tex]y=\frac{5}{6} x-2[/tex]
Step-by-step explanation:
Point-slope form:
[tex]y-y_1=m(x-x_1)[/tex]where [tex](x_1, \ y_1)[/tex] are coordinates of a point that the line passes through, and [tex]m[/tex] is the slope of the line.
We are given two points that the line passes through, but we are not given the slope.
We can find the slope by using the slope formula:
[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]where [tex](x_1, \ x_2)[/tex] and [tex](y_1, \ y_2)[/tex] are two points that the line passes through.
Substitute (-6, -7) and (6, 3) into the slope formula:
[tex]\frac{3-(-7)}{6-(-6)} = \frac{10}{12} = \frac{5}{6}[/tex]The slope of this line is 5/6. Now we are able to use the point-slope equation to find the slope-intercept equation [tex](y=mx+b)[/tex] of this line.
Substitute a point that the line passes through and the slope of the line into the point-slope equation. I'm using the point (6, 3).
[tex]y-y_1=m(x-x_1)[/tex][tex]y-(3)=\frac{5}{6} (x-(6)[/tex][tex]y-3=\frac{5}{6} (x-6)[/tex]Distribute 5/6 inside the parentheses.
[tex]y-3=\frac{5}{6} x-\frac{30}{6}[/tex][tex]y-3=\frac{5}{6} x-5[/tex]Add 3 to both sides of the equation.
[tex]y=\frac{5}{6} x-2[/tex]This is the equation of the line that passes through (-6, -7) and (6, 3) in slope-intercept form.
