The slope of the line y = 2x + 5 is 2 obtained by comparing it with slope intercept form y=mx+b, where m is slope.
The slope represents the rate at which the line is increasing or decreasing as you move along the x-axis.
The slope of a linear equation in the form y = mx + b is represented by "m."
In this case, "m" is 2, which means the slope of the line y = 2x + 5 is 2.
Since the slope is positive (2), it means that as x increases by 1 unit, y increases by 2 units, and as x decreases by 1 unit, y decreases by 2 units.
The slope of 2 indicates that the line is inclined, and it rises at a steady rate of 2 units for every 1 unit moved to the right along the x-axis.
Hence, slope of the line y = 2x + 5 is 2.

Quante’ had 15.3 feet of fishing line. He cut off a piece and had 3.2 inches left. How long was the piece he cut off?
Answer:
180.4 inches (15.033 feet)
Step-by-step explanation:
To solve this, we convert 15.3 feet to inches. We do this by multiplying 15.3 by 12. This gets us 183.6. Now, we subtract 3.2 from 183.6. This gets us 180.4. That means the piece cut off of 180.4 inches long. To convert this to feet, we divide by 12. That gets us 15.033. That means the piece cut off is 180.4 inches long, or 15.033 feet long.

Which relationship is a function?
Answer:
the first one
Step-by-step explanation:
remember, in a function, x can only have one y, whereas y can have more than one x
Answer:
The first one (the one with the months)
Step-by-step explanation:
A function is when an x value doesn't have more that one y value (y can have more than one x value, though). On the teachers and pets one, Ms. Valverde has two pets, so that doesn't count. On the shapes one, the orange square is pointing to another orange square and a triangle, so that doesn't count. The last one has 7 equaling to 12 and 13, so that doesn't count. The one with the months doesn't have any x values with more than one y value, so it is a function.

Determine which representation corresponds to a decreasing speed with an increasing time. A 2-column table with 5 rows. The first column is labeled time with entries 0, 2, 4, 6, 8. The second column is labeled speed with entries 0, 15, 25, 45, 70. A graph shows time (seconds) labeled 1 to 8 on the horizontal axis and speed (feet per second) on the vertical axis labeled 1 to 8. A line shows the speed starting at 7 feet per second and continuing to lose speed over 5 seconds.
Answer:it c
Step-by-step explanation:
The Graph representation corresponds to a decreasing speed with an increasing time.
What is Graph?In mathematics, a graph is a visual representation or diagram that shows facts or values in an ordered way. The relationships between two or more items are frequently represented by the points on a graph.
Given:
We have the table
Time Speed
0 0
2 15
4 25
6 45
8 70
So, the rate of change
= (15-0) / (2-0)
= 15/2
= 7.5
and, the rate of change
= (25-15) / (4-2)
= 10/2
= 5
and, the rate of change
= (45-25) / (6-4)
= 20/2
= 10
and, the rate of change
= (70-45) / (8-6)
= 25/2
= 12.5
As, the rate of change is increasing.
and, from the graph the slope is decreasing as time increases.

(8x + 40)°
Solve this please
Answer:
it is an equalateral triangle on a line. equalateral triangle all angles are the same. 180 degrees in a triangle so the angle in the triangle must be 60 degrees.

Rectangle N NN has an area of 5 55 square units. James drew a scaled version of Rectangle N NN and labeled it Rectangle P PP. Rectangle P Rectangle P What scale factor did James use to go from Rectangle N NN to Rectangle P PP?
Answer:
The scaled factor is 3.
Step-by-step explanation:
Consider the figure shown below:
It is given that: A rectangle N has an area of 5 square units. James drew a scaled version of Rectangle N and labeled it Rectangle P.
We need to find the scale factor which is used by James.
First, we will calculate the area of Rectangle P by counting the number of squares shown in the figure.
Area of rectangle P = 45 square unit
Let x be the scaled factor.
To scale the rectangle we need to multiply both the length and breadth of the rectangle N by x and the scaled area should be equal to 45.
[tex][x\times \text{Length} ][x \times \text{breadth}]=45[/tex]
[tex]x^2(\text{Length} \times \text{breadth})=45[/tex]
It is given that area of the rectangle N is 5 square units, so put length time breadth as 5.
[tex]x^2(5)=45[/tex]
[tex]x^2=9[/tex]
[tex]x=3[/tex]
Hence, the scaled factor is 3.

simplify:-5 1/4-(-7 1/2)
Answer:
D. 2 1/4.
Step-by-step explanation:
First, convert both -5 1/4 and -7 1/2 into improper fraction. These would be -21/4 and -15/2.
-21/4 - (-15/2)
Two negatives in a row make a positive.
-21/4 + 15/2
Double both the numerator and denominator of 15/2 to make it have the same denominator as -21/4. This would 30/4.
-21/4 + 30/4
Put -21 + 30 over 4 to make it a single fraction.
(-21 + 30)/4
Add -21 and 30 to get 9.
9/4
Convert 9/4 into a mixed number: 2 1/4
The answer to -5 1/4 - (-7 1/2) is 2 1/4, which is D.
Based on the information presented what do think Manny should decide? Option #1: Keep the old car Option #2: Buy the fuel-efficient used car Option # Number
Answer:
Manny should keep the old car since he gets to spend less on it in three years compared to getting the fuel-efficient car.
Step-by-step explanation:
Step 1:
Number of miles Manny commutes per week = 160
Cost per gallon of gasoline. = $2.9
Mileage of old car = 20 miles per gallon
Maintenance cost per year of old car = $760
Cost of new car = $7000
Maintenance cost per month of new car = $10
Mileage of new car = 31 miles per gallon
Step 2:
There are 52 weeks in a year. Total distance Manny will commute in 3 years = 160 * 52 * 3 = 24960 miles
Maintenance cost of old car in 3 years = $760 * 3 = $2280
Maintenance cost of new car in 3 years = $10/month * 12 months * 3 = $360
Gasoline usage of old car in 3 years = 24960 miles/20 miles per gallon = 1248 gallons
Cost of gasoline = 1248 * $2.9 = $3619.2
Gasoline usage of new car in 3 years = 24960 miles/31 miles per gallon
Cost of gasoline = $2.9 * 24960 miles/31 miles per gallon = $2334.97 or approximately $2335
Step 3:
Total expenditure on old car for 3 years = $2280 + $3619.2 = $5899.2
Total expenditure on new car for 3 years = $7000 + $360 + $2335 = $9695
From the calculations above, Manny will spend $5899.2 on the old car compared to $9695 on the new car in three years.
Therefore, Manny should keep the old car since he gets to spend less on it in three years compared to getting the fuel-efficient car.
