Answer:
- 2 ft/ s
Step-by-step explanation:
The rate of change is the slope m of the line.
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 80) and (x₂, y₂ ) = (40, 0) ← 2 points on the line
m = [tex]\frac{0-80}{40-0}[/tex] = [tex]\frac{-80}{40}[/tex] = - 2
Rate of change is - 2 ft/ s
20 points and brainiest for the correct answer
On a coordinate plane, a line goes through (0, negative 5) and (5, 0).
A system of equations consists of a line s of the equation y = x - 5 that is graphed in orange, and a line t that passes through the points (0, 2) and (8, -4). The equation of line t is y = -[tex]\frac{3}{4}[/tex]x + 2.

What is the length of side AC
Answer:
7 Units.
Step-by-step explanation:
First of all, you could just count the units, but that's not really too effective. Otherwise, you could start from the coordinates of the "C" point, and see how it's at -Y = -5. Therefore, to get to the line separating the two points, you would have to subtract 5 from 5 to get to the line. Now, you look at point "A". It's Y coordinate is 2. Therefore, adding 5 and 2 together gives you 7 units.

The length of one side of a shoebox is 8 centimeters more than twice the width. The base of the shoebox has an area of 72 square centimeter.
Write an equation to represent this situation with w representing the width in centimeter
Answer: [tex]w^2+4w-36=0[/tex]
Step-by-step explanation:
Let w = width of the base of the shoebox.
As per given ,
Length = 8+2w centimeters
Area of base = 72 square centimeter
Area of rectangle = Length x width
[tex]\Rightarrow\ 72=w(2w+8)\\\\\Rightarrow\ 72= 2w^2+8w\\\\\Rightarrow\ 2w^2+8w-72=0\\\\\Rightarrow\ w^2+4w-36=0[/tex]
Required equation: [tex]w^2+4w-36=0[/tex]

Harold and his friend Bill each collect vintage action figures. Harold already has 18
action figures and adds 3 more figures to his collection each month. Bill already has 24
action figures and adds 2 more to his collection each month. Let x represent the
number of months, and y represent the number of action figures. Which equations can
be used to find how long it will take before the friends each have the same number of
action figures?
Answer:
6 months
Step-by-step explanation:
A. y = 8 − 7x
B. y = 7x + 8
C. y = 7x − 8
D. y = 8x − 7
Answer:
I'm getting
y=-7x+8
The 7 is negative for me..You should maybe try yourself too and see what you get I might have made a mistake
Step-by-step explanation:
I'm guessing you live somewhere in the U.S. so I'll use the equation you use there
Equation:
[tex]y = mx + b[/tex]
[tex]m = \frac{y1 - y2}{x1 - x2} [/tex]
first pick two points
I'll pick (0,8) and (1,1)
[tex]m = \frac{8 - 1}{0 - 1} = \frac{7}{ - 1 } = - 7[/tex]
this means that the slope is -7
So far the equation will look like this
[tex]y = - 7x + b[/tex]
to get b pick one point, I'll pick (0,8) and replace y and x
[tex]8 = - 7 \times 0 + b[/tex]
when you solve this you'll get b
[tex]b = 8[/tex]
So the equation will look this
[tex]y = - 7x + 8[/tex]

Step-by-step explanation:
The value of f(0) from the graph of f(x) is (a) 12 only
What are functions?Functions are used to represent graphs, equations, ordered pairs and relations.
To interpret the value of the function, we start by reading the graph.
From the graph, the value of the function when x = 0 is 12
This means that:
[tex]f(0) = 12[/tex]
Hence, the value of f(0) from the graph of f(x) is (a) 12 only

Step-by-step explanation:
Answer:
17. C
18. C
Step-by-step explanation:
The greater the negative number, the less the number values. -10 is smaller than -8 because -10 is farther away from the number line to the left.
Go in terms of the tenths place. If its smaller than the number will be less than the bigger numbers. 0.227 is bigger than 0.18 because it has a 2 in the tenths place.

Step-by-step explanation:
Yo no comprehendo espanol mucho, but I'll try
12y + 15 + y - 36y - 9 = y
Rearrange
12y + y (-y) + 15 (-15) - 36y - 9 (+9)= y (-y) (-15) (+9)
12y - 36y = - 15 + 9
-24y = - 6
Divide both sides by - 24 (Take note of the signs (+) (-))
-24y/-24 = - 6/-24
