Ways to find the perpendicular line of a linear equation are by solving for y, convert the equation of the given line into slope-intercept form.
Describe perpendicular.A straight line that forms a 90° angle with another line is said to be perpendicular. A small square is placed between two perpendicular lines, as seen in the illustration, to indicate a right angle, also known as a 90° angle. The two lines in this instance are considered to be perpendicular to one another because they intersect at a straight angle.
Given
Ways to find the perpendicular line of a linear equation are,
First, by solving for y, convert the equation of the given line into slope-intercept form.
You obtain y = -2x + 5, indicating a -2 slope. Since the slopes of perpendicular lines are opposite-reciprocal, the slope of the line we're looking for is 1/2.
By entering the supplied point into the formula y = 1/2x + b and solving for b, we arrive at the value b = 6.

Find the constant proportionality (r) using the value for r, enter an equation in the form of. C=rg that represents the relationship between the number of the gallons of gasoline used (g) and the total cost(c)
Answer:
3.333
C = 3.3333g
Step-by-step explanation:
Given the relation : C = rg
C = Total cost of gasoline
g = Number of gallons of gasoline used
r = constant of proportionality
Picking any point on the graph :
At cost, c = $30
Number of gallons of gasoline used, g = 9
Putting the values into our equation :
C = rg
$30 = r * 9
30 = 9r
Divide both sides by 9
30/9 = 9r / 9
3.333 = r
Hence, constant of proportionality, r = 3.333

Slope- intercept equation from a graph
Find the equation of the line
We can find the slope using any two points on the line. Readily identifiable are the points (2, 0) and (0, 3), from which we can find the slope:
[tex]\text{slope} = m=\frac{y_2-y_1}{x_2-x_1} \\ m = \frac{3-0}{0-2} = -\frac{3}{2}.[/tex]
The y-intercept is the y value when x = 0, which we already know is 3. So, the slope-intercept equation of this line is:
[tex]y=-\frac{3}{2}x+3.[/tex]

Reggie deposited $1200 into an account that earns 5% compound interest yearly if he does not deposit any more to the account or take any money out of the account how much interest will Reggie earn on his investment at the end of four years round your answer to the nearest whole number
Answer:
$1,440
Step-by-step explanation:
1,200 / 10 = 120. 120 is 10%. So this means that 5% is $60. 60 x 4 = 240.
1,200 + 240 = 1,440

An aquarium holds 11.04 cubic feet of water, and is 2.3 feet long and 1.2 feet wide. What is its depth? Round your answer to the nearest whole number. The depth is feet.
Answer:
Depth is 4 feet.
Step-by-step explanation:
Given:
Length of an aquarium is 2.3 feet
Width of an aquarium is 1.2 feet
Volume of an an aquarium is 11.04 cubic feet
To find: depth of an aquarium is 2.3 feet
Solution:
If [tex]l,b,h[/tex] denote length, width and height of a cuboid then volume (V) of a cuboid is equal to [tex]lbh[/tex]
[tex]l=2.3[/tex] feet
[tex]b=1.2[/tex] feet
[tex]V=11.04[/tex] cubic feet
[tex]11.04=2.3(1.2)h\\h=\frac{11.04}{2.3(1.2)}\\h=\frac{11.04}{2.76}[/tex]
[tex]h=4[/tex] feet
Therefore,
depth is 4 feet.
Maya is building a sandbox that is 48 inches wide. The length of the sandbox is four times the wldth of the sandbox. What is the perimeter of the sandbox?
Answer: 480 in.
Step-by-step explanation:
Given
The width of the sandbox is 48 in.
The length of the sandbox is four times the width
[tex]\therefore L=4\times 48=192\ in.[/tex]
Perimeter is the sum of the sides of the shape
The perimeter of the box is
[tex]P=2[48+192]=480\ in.[/tex]
Answer:
the perimeter of the sandbox is 480 inches
Step-by-step explanation:
The computation of the perimeter of the sandbox is shown below:
Since the width is 48 inches
And, the length would be four times the width i.e.
= 4 × 48
= 192 inches
Now the perimeter of the sandbox is
= 2( length + width)
= 2 (192 inches + 48 inches)
= 480 inches
Hence, the perimeter of the sandbox is 480 inches

What is the measure of each angle?? NEED HELP ASAP
Answer:
The base angles are 64. The top angle is 52
Step-by-step explanation:
Since this is an icoseles triangle, the base angles are equal so:
8x - 16 = 6x + 4
8x - 6x = 4 + 16
2x = 20
x = 10
8x - 16
8(10) - 16
80 - 16
64
The top angle (x)
x + 64 + 64 = 180
x + 128 = 180
x = 52

Find the equation of the graphed line.
Answer:
d. y = -⁷/6x - 7
Step-by-step explanation:
✔️First, find the slope (m) using two points on the line, (-6, 0) and (0, -7):
Slope (m) = change in y/change in x
Slope (m) = (-7 - 0)/(0 - (-6))
Slope (m) = -7/6
✔️Determine the y-intercept (b):
The line intercepts the y-axis at -7. Therefore,
b = -7.
✅To write the equation, substitute m = -⁷/6 and b = -7 into y = mx + b
Thus:
y = -⁷/6x + (-7)
y = -⁷/6x - 7
Ashik claims that the graph on the right is the correct interpretation of the scatterplot, but his friend Shelby claims that the graph on the left is correct.
Shelby’s Graph Ashik’s Graph
A graph titled Shelby's Graph has points that form a curved line. A line with negative slope is drawn. A graph titled Ashik's Graph has points that form a curved line. A curved line is drawn to connect the points.
Who is correct and why?
Shelby is correct because the line of best fit has a negative slope and the trend shows a decrease in y values as the x values increase.
Shelby is correct because the line of best fit matches the points as closely as possible with a weak correlation.
Ashik is correct because the points are a strong correlation to this nonlinear association.
Ashik is correct because points with a weak correlation can never have linear association.
