Jenny wants to rent a truck. She contacts two truck companies. Avis truck company charges $20 plus $2 per mile. Budget truck company charges $3 pe mile. At how many miles will the charge be the same for both companies ?
Answer: 20 miles
Step-by-step explanation:
From the question, we are informed that Avis truck company charges $20 plus $2 per mile and that Budget truck company charges $3 per mile.
Let the number of miles that the charge will be the same for both companies be represented by x. This can then be used to form an equation as:
20 + 2x = (3 × x)
20 + 2x = 3x
3x - 2x = 20
x = 20
The charge will be thesame at 20 miles

Answer:
The measure of the largest triangle is 72.
Step-by-step explanation:
Set up an equation to find the angle. note that angles in a triangle sum to 180.
With this information, we can set up an equation:
24x + 21x + 15x = 180
(add the x terms)
60x = 180
(divide both sides by 60)
x = 3
We now know what x equals. Now, we can multiply 3 by the largest angle of all- 24.
24 * 3 = 60.

Lucy has 30 bean plants, 24 tomato plants, and 18 pepper plants. She wants to put the plants in rows with only 1 type of plant in each row. Each row will have the same number of plants. How many plants can Lucy put in each row?
30 because the max amount of plants is 30. so you would need 2 more on tomato nd 12 more on pepper

The best equation to graph from is the point slope form of a line. True or false?
Answer:
i say yes
Step-by-step explanation:
this is because it will give you the point to start with and the slope so you will already have all the information to graph
what type of relationship is y=3x+5 and y=-2x+1
This is a linear relationship.
Linear relationship is a statistical term used to describe a straight-line relationship between two variables. These two equations are written in the typical slope-intercept form of y = mx + c, this function creates a straight line when plotted.
suppose a triangle with the vertices a(-2,4)b (-1,-3) and c (4,-2) were dilated with the center of dilation at the origin and with a scale factor of 2.5 what will be the ordinates be for c'

HELP ME PLEASE!!!ITS DUE TODAY!!IF YOU DO NOT KNOW DONT ANSWER PLEASE!!!;(
Step-by-step explanation:
When dealing with graphs, involving points in between numbers, we have to carefully look at the x and y axis.
On the graph, the y-axis is going by 2s: 0, 2, 4, 6, 8, 10
On the x-axis, it's going by 1s: 0, 1, 2, 3, 4, 5, 6
Between 2 and 4 is 3
Between 4 and 6 is 5
Between 6 and 8 is 7
Between 8 and 10 is 9
Between 2 and 3 is 2.5
Between 3 and 4 is 3.5
Between 4 and 5 is 4.5
Between 5 and 6 is 5.5
Between 6 and 7 is 6.5
Between 7 and 8 is 8.5
Between 8 and 9 is 8.5
Between 9 and 10 is 9.5
Between 10 and 11 is 10.5
You get to see the pattern going on here...
On point E, we can see that the x-axis is 2.
Now on the y-axis, it is between 6 and 7. But if you look closely, you'll see that it's not on the line, that indicates 6.5.
So we find the median...
6, 6.1, 6.2, 6.3, 6.4, 6.5 6.2 and 6.3 are on the medium
[tex]\frac{6.2 + 6.3}{2}[/tex] = 6.25 Answer on E: (2, 6.25)
On point F, we can see that the x-axis is 3.
On the y-axis, it is between 8 and 10, which would be 9, BUT, look closely that it's also between 9 and 9.5.
The answer would be 9.5, but it is SLIGHTLY below 9.5, so I think it's 9.4
Answer on F: (3, 9.4)
On point G, the x-axis is between 3 and 4, so it's 3.5.
On the y-axis, we know it's going by 2s. We can see that G is between 10 and 12, so it would be 11. Because it is on that thin line, as you can see.
Answer on G: (3.5, 11)

A line passes through the point (8, -2) and has a slope of 5/4. Write an Equation in point-slope form for this line
Answer:
y=5/4x-8
Step-by-step explanation:
Answer:
[see below]
Step-by-step explanation:
General Point Slope Form is:
[tex]y-y_1=m(x-x_1)\\\\\rightarrow \text{m - slope}\\\\\rightarrow (x_1,y_1)\text{ - given point}[/tex]
We are given the slope of (5/4) and the point of (8, -2).
Replace the variables with their appropriate values:
[tex]x_1 \rightarrow8\\\\y_1\rightarrow-2\\\\m\rightarrow\frac{5}{4}\\\\\text{Replace } x_1, y_1, \text{and } m \text{ with the appropriate values.}\\\\y-y_1=m(x-x_1)\rightarrow y-(-2)=\frac{5}{4}(x-8)\\\\\text{Simplify:}\\\\y-(-2)=\frac{5}{4}(x-8)\rightarrow y+2=\frac{5}{4}(x-8)\\\\\\\text{Our final answer is:}\\\\ \huge\boxed{y+2=\frac{5}{4}(x-8)}[/tex]
Hope this helps.

During a high school baseball tournament, Lexile hits a pitch and the baseball stays in the air for 4.42 seconds. The function describes the height over time, where h is its height, in yards, and t is the time, in seconds, from the instant the ball is hit: h(t) = - 5t ^ 2 + 22t + .5
Answer:
a) The maximum height that the ball reaches is 73.1 meter
b ) The time elapsed when the ball reaches its maximum height of flight = 2.2 seconds
Step-by-step explanation:
The complete question is
During a high school baseball tournament, Lando hits a pitch and the baseball stays in the air for 4.42 seconds. The function h(t) = -5t2 + 22t + 0.5 describes the height over time, where h is its height, in meters, and t is the time, in seconds, from the instant the ball is hit. a. What is the maximum height the ball reaches? b. What will be the time elapsed when the ball reaches its maximum height of flight?
Solution:
For maximum height
[tex]\frac{dh}{dt} =0[/tex]
[tex]\frac{d(5t^2 + 22t + 0.5)}{dt}\\ 10t + 22 = 0\\t = 2.2[/tex]seconds
a) Maximum height
[tex]5 * t^2 + 22t + 0.5[/tex]
[tex]= 5 * 2.2 *2.2 + 22 * 2.2 + 0.5 \\= 73.1[/tex]
b) Time elapsed when the ball reaches maximum height is 2.2 seconds
