The slope is 2 using the slope-intercept form. As the slope of the line in slope-intercept form is the coefficient of x, the slope of the line is -2.
what is slope ?The slope of a line governs its steepness. Using mathematics, the gradient is expressed as "gradient overflow" (the change in y divided by the change in x). The slope is the ratio of the vertical (rise) to the horizontal (run) change in distance between any two sites. Every time the equation for a straight line is written as y = mx + b, the slope-intercept representation of the equation is utilized. At the location of the y-intercept, the line has a slope of m, b, and c. (0, b). As an example, the y-intercept of the equation y = 3x - 7 has a value of 3. (0, 7).

The slope is 2 using the slope-intercept form.
As the slope of the line in slope-intercept form is the coefficient of x, the slope of the line is -2.
Divide the difference in elevation between two points by the distance between them, multiply the result by 100, and that is the percent slope. The term "rise" refers to the elevational difference between two places. The run is the distance separating the points. The formula for percent slope is (rise / run) x 100.

help me plz !!!!!!!!!!
Step-by-step explanation:
Since y = x + 3
Substitute the value of y for each one into the equation
1. y = 4
4 = x + 3
4 - 3 = x
x = 1
2. y = 8
8 = x + 3
8 - 3 = x
x = 5
3. y = 5
5 = x + 3
5 - 3 = x
x = 5

Which statement(s) about the line
below are true? Select all that apply.
A The x-intercept is -8.
B The line has a positive slope.
C The y-intercept is 4.
D The line has a negative slope.
Answer: A, B, and C.
Step-by-step explanation: The answers you have selected in the picture are correct.
These are the actual claims made regarding the line:
The x-intercept is at - 8 because y = 0 when x = -8.
The line is growing and has a positive slope.
As soon as x = 0 and y = 4, the y-intercept is at 4.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
The true statements about the line are,
The x-intercept is at - 8, as when x = - 8 y = 0.
The line has a positive slope as it is increasing.
The y-intercept is at 4 as when x = 0 y = 4.

Select the three inequalities that have n = 3 in the solution set
A. n + 5 < 9
B. 13 n < 1
C. 3n + 1 >7
D. 3n > 9.5
E. n-2<5
Answer:
Its just E
I'm sorry if I'm wrong
Answer: A, C, E
Solve for all the inequalitites.
n + 5 < 9
n < 9 - 5
n < 4
∴ n = 3 is a part of the solution set.
13n < 1
n < 1/13
∴ This definitely doesn't include n = 3.
3n + 1 > 7
3n > 6
n > 2
∴ n = 3 is part of the solution because n is larger than 2.
3n > 9.5
n > 9.5 ÷ 3
n > 3.16666666
∴ n = 3 is not part of the solution set.
n - 2 < 5
n < 5 + 2
n < 7
∴ n = 3 is a part of the solution set.
help i dont understand how to do this the question is "Put your answer in decimal form."
Answer:
x = 2.5
Step-by-step explanation:
Hypotenuse ² = opposite ² + adjacent ²
(x + 4)² = x² + 6²
x² + 8x + 16 = x ² + 6²
x² + 8x + 16 - x² = 6²
8x + 16 = 36
8x = 36 - 16
8x = 20
x = 20/8
x = 2.5

which of the given values will make the inequality n-93>175 true?
n=82
n=105
n=268
n=300
n=312
Answer:
n = 300 and n = 312
Step-by-step explanation:
n - 93 > 175
n > 175 + 93
n > 268
Therefore only the two last answers are are possible n values (n has to be more than 268, not equal)
The two numbers 300 and 312 will make the inequality n-93>175 true which are correct option (D)300 and (E)312.
What is inequality?Inequality is the defined as mathematical statements that have a minimum of two terms containing variables or numbers is not equal.
Given inequality as:
n - 93 > 175
n > 175 + 93
n > 268
Therefore, n must be greater than 268 and not equal.
Hence, the two numbers 300 and 312 will make the inequality n-93>175 true.

Each pair of polygons is similar. Find each missing side measure. two polygons 12 on top 5 on bottom second polygon 48 on top x on bottom
Answer:
[tex]x = 20[/tex]
Step-by-step explanation:
Given
First Polygon:
[tex]Top = 12[/tex]
[tex]Bottom =5[/tex]
Second Polygon
[tex]Top = 48[/tex]
[tex]Bottom =x[/tex]
Required
Find x
Since both polygons are similar, then:
[tex]Ratio = Top:Bottom[/tex]
For the first:
[tex]Ratio = 12:5[/tex]
For the second
[tex]Ratio = 48:x[/tex]
Equate both ratios
[tex]12:5 = 48:x[/tex]
Express as fraction
[tex]\frac{12}{5} = \frac{48}{x}[/tex]
Cross Multiply
[tex]12 * x = 48 * 5[/tex]
Solve for x
[tex]x = \frac{48 * 5}{12}[/tex]
[tex]x = \frac{240}{12}[/tex]
[tex]x = 20[/tex]
A cell phone costs $750 and loses 28% of its value each year. Write an exponential decay function to represent this situation.
1. f(x)= 750 • 0.72^x
2. f(x)= 0.72 • 750^x
3. f(x)= 750 • 0.28^x
4. f(x)= 0.28 • 750^x
Answer:
1. [tex]f(x) = 750\cdot 0.72^{x}[/tex]
Step-by-step explanation:
The cell phone experiments an exponential depreciation, which is defined by the following formula:
[tex]f(x) = C_{o}\cdot (1-r)^{x}[/tex], for [tex]0<r< 1[/tex]. (1)
Where:
[tex]C_{o}[/tex] - Initial cost, measured in monetary units.
[tex]r[/tex] - Depreciation rate, no unit.
[tex]x[/tex] - Time, measured in years.
[tex]f(x)[/tex] - Current value of the cell phone, measured in monetary units.
If we know that [tex]C_{o} = \$\,750[/tex] and [tex]r = 0.28[/tex], then the exponential decay function that represents the situation is:
[tex]f(x) = 750\cdot 0.72^{x}[/tex]
Which means that correct answer is 1.

Steve studies math for 7/8 of an hour and history for 2/3 of an hour. How many hours did he study?
Answer:
The answer is 1 13/24 hours or 1 hour, 32.5 minutes
Step-by-step explanation:
Find a common multiple of the denominators 3 and 8, which would be 24. Convert the fractions:
7/8 x 3/3 = 21/24.
2/3 x 8/8 = 16/24
Add the two numerators = 37/24 or 1 13/24.
1/24 of an hour is 2.5 minutes, so 13/24 is 32.5 minutes.
The answer is 1 13/24 hours or 1 hour, 32.5 minutes
