Answers
Answer:
y = 2x + 20
Step-by-step explanation:
You can put the equation into the form y = mx + b where m is the slope and b is the y-intercept.
You already have that the slope is 2,so then the equation would be y = 2x + b.
Since you know that x = - 6 and y = 8 is a solution, you can substitute those into the equation and find out what b would have to be for it to be true.
[tex]8 = -6*2 +b \\8 = -12 +b\\b = 20[/tex]
This means that the equation is y = 2x + 20.

Answer:
C. 179 ft²
Step-by-step explanation:
Area of circular path or walkway
= π × (R + r) × width
Where
R= Outer radius
r = Inner Radius
Diameter = 16 feet
Width = 3 feet
Inner Radius = Diameter/2
= 16 feet/2 = 8 feet
Outer Radius = 8 + 3 = 11 ft
Hence:
= π × (11 + 8) × 3
= π × 19 × 3
= 179.07078125 ft²
Approximately = 179 ft²
The area of the circular walkway = 179ft²

the instructions say to write an equation for the graphs in slope-intercept form.
Answers
Answer: 16) y=-0.5x+3 and 17) y=2x-3
Step-by-step explanation:
16: The slope-intercept form of a line is y=mx+b, where m is the slope, and b is the y-value at the y-intercept.
Since y=3 at x=0, the y-intercept is (0,3), and b=3.
Slope=[tex]\frac{y_{2} -y_{1} }{x_{2}-x_{1} }[/tex] where ([tex]x_{1} ,y_{1}[/tex]) and ([tex]x_{2} ,y_{2}[/tex]) are two points on the line. Choose (0,3) and (2,2):
Slope=[tex]\frac{2-3}{2-0}[/tex]=-0.5
Plug m=-0.5 and b=3 into y=mx+b:
y=-0.5x+3
17: The slope-intercept form of a line is y=mx+b, where m is the slope, and b is the y-value at the y-intercept.
Because y=-3 at x=0, the y-intercept is (0,-3), and b=-3.
Slope=[tex]\frac{y_{2} -y_{1} }{x_{2}-x_{1} }[/tex] where ([tex]x_{1} ,y_{1}[/tex]) and ([tex]x_{2} ,y_{2}[/tex]) are two points on the line. Choose (0,-3) and (1,-1):
Slope=[tex]\frac{-3-(-1)}{0-1}[/tex]=[tex]\frac{-2}{-1}[/tex]=2
Plug m=2 and b=-3 into y=mx+b:
y=2x-3

A contractor bought a rectangular piece of land that has a perimeter of 200 feet. The ratio of the land's length to width is 9 : 16.
Answers
Answer:
Length = 36feet
Width = 64 feet
Area = 2304 ft²
Step-by-step explanation:
Complete Question
A contractor bought a rectangular piece of land that has a perimeter of 200 feet. The ratio of the land's length to width is 9 : 16. Find the area of the land
Perimeter of the land = 2(L+W)
L is the length
W is the width
Given
Perimeter = 200 feet
If the ratio of the land's length to width is 9 : 16, then;
L/W = 9/16
9W = 16L
W = 16/9 L
Substitute into the formula
P = 2(L + 16/9 L)
P = 2(25L/9)
P = 50L/9
200 = 50L/9
1800 = 50L
L = 180/5
L = 36
Since W = 16/9 L
W = 16/9 * 36
W = 16 * 4
W = 64 feet
The area of the land = Length * Width
The area of the land = 36*64
The area of the land = 2304ft²

Find the equation of a line with a slope of -4 that passes through the point (-3, 8).
Answers
Answer:
The equation of line is y = -4x -4.
Step-by-step explanation:
Given that:
Slope of the line = -4
Line passes through the point ( -3, 8)
The general equation of line is given by;
y - y1 =m(x-x1)
Putting the point and slope in equation
y - 8 = -4(x - (-3))
y - 8 = -4(x+3)
y - 8 = -4x - 12
y = -4x - 12 + 8
y = -4x -4
Hence,
The equation of line is y = -4x -4.
