A truck can be rented from Company A for $130 a day plus 50.30 per mile. Company B charges 570 a day plus 50.70 per mile to rent the same truck. Find the
number of miles in a day at which the rental costs for Company A and Company B are the same.
Answer:
Not possible
Step-by-step explanation:
You use the formula y = mx + b to make equations for both situations then solve from there
Let x be miles driven
Company A:
y = 50.30x + 130
Company B:
y = 50.70x + 570
You solve by making the equations equal each other to figure out the variable (miles driven)
50.70x + 570 = 50.30x + 130
50.70x + 570 - 50.30x + 130 - 50.30x
0.4x + 570 - 570 = 130 - 570
0.4x = -440
x = -1100
Therefore there is no amount of miles you can drive for Company A and Company B to have the same rental costs

The equation y-4=-3(x+4) is written in point-slope form. What is the y-intercept of the line
Answer:
-8
Step-by-step explanation:
you need to rewrite it in y=mx+b form where b-is the y-intercept
y-4= -3(x+4)
distribute
y-4 = -3x-12
isolate y
y= -3x-8
compare this with the y=mx+b so y-intercept is -8
Answer:
(0,-8)

Answer:
The line equation in slope-intercept form is:
[tex]y\:=-\frac{2}{5}x+4[/tex]
Hence, option D is true.
Step-by-step explanation:
Given the points
(0, 4)(5, 2)Finding the slope between the points
[tex]\left(x_1,\:y_1\right)=\left(0,\:4\right),\:\left(x_2,\:y_2\right)=\left(5,\:2\right)[/tex]
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{2-4}{5-0}[/tex]
[tex]m=-\frac{2}{5}[/tex]
As the y-intercept is obtained by setting the value x = 0.
As we know that when x = 0, the vale of y-intercept y = 4
so the y-intercept is b = 4.
As the slope-intercept form is
substituting the slope m = -2/5 and the y-intercept b=4
[tex]y = mx+b[/tex]
[tex]y\:=-\frac{2}{5}x+4[/tex]
Therefore, the line equation in slope-intercept form is:
[tex]y\:=-\frac{2}{5}x+4[/tex]
Hence, option D is true.

Work out the area of the rectangle.
Answer:
12544cm2
Step-by-step explanation:
if the the circles touch each other, the length is to be gotten by
a) getting the diameter.
- as the radius is 28cm, the diameter of each circle is 56cm.
- 2 circles are connected enabling us to form a horizontal line with the length of 112cm.
b) inside the triangle
- looking keenly you can see three dots at the center of each circle forming a triangle. as we know each circle is connected to 2 others. so the distance from one radius to the other forms a diameter.
-connect the dots, radii from 1 circle to the other, and assign them their measurements,. remember that they lines act as diameters
c) properties of a triangle
-forming that, you will notice that all sides are equal making it an equilateral triangle and equilateral triangles are only able to fit inside parallelograms whose sides are ALL EQUAL.
- got the trick! now we know that all the sides are equal and one side is of the rectangle is 112cm, automatically all sides become 112cm.
d) area
-area will be
S x S
112 x 112
=12544cm2

Rewrite the formula for the base b₂ will be given as b₂ = 2A / h + b₁.
What is a trapezium?It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a trapezium, one pair of opposite sides are parallel.
The area of a trapezoid is calculated using the formula below, where A is the area of the trapezoid, b₁ and b₂ are the bases of the trapezoid, and H is the height of the trapezoid.
Then the area of the trapezoid will be
A = [(b₁ + b₂) / 2] · h
Rewrite the formula to find the base b₂ will be given as,
A = [(b₁ + b₂) / 2] · h
2A / h = b₁ + b₂
b₂ = 2A / h + b₁

Write the equation of the line that goes through the point (1,-7) and m=3.
Answer:
y = 3x - 10
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 3 , thus
y = 3x + c ← is the partial equation
To find c substitute (1, - 7) into the partial equation
- 7 = 3 + c ⇒ c = - 7 - 3 = - 10
y = 3x - 10 ← equation of line

Hi, this question is in calculus. I am trying to write an equation in slope-intercept form about data usage that increase in 32.5 million every 4 years.
Answer:
we have an increase of 32.5 million every 4 years.
Then the increase per year is:
32.5 mill/4y = 8.125 million per year.
then if we define the variable x, as the number of years, we can write the linear equation as:
y = x*8.125 million/year + b
where b is the initial amount, that is not shown in the question, so i will just leave it like that.
You can see that when we have x = 4 years we have:
y(4 years) = (4 years)*(8.125 million/year) + b = 32.5 million + b.
Then after 4 years, we have an increase of 32.5 million, that is the thing we knew at the beginning.
How can you find the sum of integers with the same sign? A add their absolute values and keep the sign of the integers B subtract their absolute values and keep the sign of the integer with the greater absolute value C subtract their absolute values and keep the sign of the integers with the smaller absolute value D add their absolute values and always add a negative sign to the sum
Answer:
Add their absolute values and keep the sign of the integers
Step-by-step explanation:
The problem can be understood with the help of an example.
Let the first number be 2 and other number be 3. If we want to add these numbers, it will be like :
Sum = 2 + 3 = 5
We can see that when we add these two numbers, we find that we add their absolute values while the sign of the integers are same.
So, if we want to find the sum of integers with the same sign, we have to add their absolute values and keep the sign of the integers.
Hence, the correct option is (a).

Describe and correct the error a student made finding the intercepts of the graph of the line 4x-6y=12
(PLEASE HELP)
Answer:the error is when 6y=12
Step-by-step explanation:
the original problem says 4x-6y=12
so when you get rid of the 4x, it should still be -6y not positive
The error is when 6y = 12 it will be -6y = 12 and the intercept would be -2.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
Given the equation is 4x-6y=12.
4x-6y=12
4 x 0 -66y = 12
-6y = 12
y =-2
4x-6y=12
4x - 6 x 0 = 12
4x = 12
x = 3
Therefore, the error is when 6y = 12 it will be -6y = 12, and the intercept would be -2.

The equation y = 3x + 1.25 represents the cost, y, in dollars, of bowling x games and renting a pair of bowling shoes. Shoes are rented for a flat rate that does not depend upon the number of games bowled. What does the slope of this equation represent? *
Answer:
Cost per game
Step-by-step explanation:
Given
[tex]y = 3x + 1.25[/tex]
Required
What does the slope represent?
First, we need to determine the slope
A general equation is of the form
[tex]y = mx + b[/tex]
Where
[tex]Slope = m[/tex]
By comparing:
[tex]y = mx + b[/tex] to [tex]y = 3x + 1.25[/tex]
[tex]m = 3[/tex]
Hence, the slope is 3
From the question we understands that a certain amount is paid per games.
This amount is represented by the rate or slope.
So:
The slope is the cost per game
