Which table contains points from the inverse of the graphed function?
The equation of the line is represented in table number 2. Then the correct option is B.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
From the graph, the y-intercept is 5. Then the equation is given as,
y = mx + 5
From the graph, the equation passes through (-4, -3). Then we have
- 3 = (-4)m + 5
- 8 = - 4m
m = 2
Then the equation is given as,
y = 2x + 5
The equation of the line is represented in table number 2. Then the correct option is B.

Ice on a lake gets thicker as long as the temperature is below freezing. On a certain lake it took 8 days for the ice to reach a thickness of 3 inches. At what rate was the ice growing over these 8 days in inches per day?
The average rate of growth of the ice can be found by dividing the thickness by the number of days of growth
The growth rate of the ice over the 8 days is 0.375 inches/day
Reason:
The known information on the ice are;
The time it took the ice to reach a thickness of 3 inches = 8 days
Required:
The (average) rate that the ice is growing in c=inches per day
Solution:
[tex]Rate \ of \ growth \ of \ ice= \dfrac{Increase \ in \ thickness}{ Time} = \dfrac{\Delta \ Thickness}{\Delta T}[/tex]
Therefore;
[tex]Rate \ of \ growth \ of \ ice= \dfrac{3 \ inches}{ 8 \ days} = 0.375 \ inches/day[/tex]

Step-by-step explanation:
you just gotta add all the side-lengths together and consider each grid square as 10 instead of 1.
so 70 + 40 + 20 + 60 + 20 + 40 i believe.
this all equals 250.
ask your teacher if its a type, because there's no 250 on there. grab a calculator or something as proof.
28. Suppose that the CPI in Year 1 is 150 and the CPI in Year 2 is 200. The rate of
inflation between Year 1 and Year 2 is:
a) 14.28%.
I b) 25%
c) 33.33%
d) 50%
The rate of inflation between year 1 and year 2, based on the CPI, is c. 33.33%.
The Consumer Price Index (CPI) allows us to calculate inflation. To find the inflation across these years, use the formula:
= (CPI₂ - CPI₁) / CPI₁ x 100%
Solving gives us:
= (200 - 150) / 150 x 100%
= 33.3%
In conclusion, the inflation is 33.3%.

What will be the equation of the altitude BM?
Answer:
BM: y = (2/3) x + 16/3 with segment length of 2.77
Step-by-step explanation:
AC formula: m = (6-0)/(0-4) = -3/2
(y-0)/(x-4) = -3/2 y = (-3/2)x + 6 ... (1)
BM slope: BM⊥ AC m = 2/3
BM formula: (y-4) / (x- -2) = (y-4) / (x+2) = 2/3
y-4 = 2/3 x + 4/3
y = (2/3) x + 16/3 ... (2) -2≤x≤0.31
intercept of AC and BM (M) from (1) and (2): (-3/2)x + 6 = (2/3) x + 16/3
(13/6) x = 2/3 x = (2/3) / (13/6) = 4/13 ≈ 0.31
y = (2/3) (4/13) + (16/3) = (8/39) + (208/39) = 216/39 = 72/13 ≈ 5.54
M (4/13 , 72/13) or (0.31 , 5.54)
segment BM = √(4/13 - -2)² + (72/13 - 4)² = √1300/169 = 2.77

Find the slope of the tangent line to the given polar curve at the point specified by the value of θ
r = 9 + 8 cos(θ), θ = π/3
The given curve has equation
r(θ) = 9 + 8 cos(θ)
and its derivative is
dr/dθ = -8 sin(θ)
When θ = π/3, we have r (π/3) = 13, and dr/dθ (π/3) = -4√3.
Differentiate these with respect to θ :
dy/dθ = dr/dθ sin(θ) + r(θ) cos(θ)
dx/dθ = dr/dθ cos(θ) - r(θ) sin(θ)
In polar coordinates, we have
y(θ) = r(θ) sin(θ)
x(θ) = r(θ) cos(θ)
and when θ = π/3, we have y (π/3) = 13√3/2 and x (π/3) = 13/2.
The slope of the tangent line to the curve is dy/dx. By the chain rule,
dy/dx = dy/dθ • dθ/dx = (dy/dθ) / (dx/dθ)
dy/dx = (dr/dθ sin(θ) + r(θ) cos(θ)) / (dr/dθ cos(θ) - r(θ) sin(θ))
When θ = π/3, the slope is
dy/dx = (-4√3 sin(π/3) + 13 cos(π/3)) / (-4√3 cos(π/3) - 13 sin(π/3))
dy/dx = (-4√3 (√3/2) + 13 (1/2)) / (-4√3 (1/2) - 13 (√3/2))
dy/dx = - 1/(17√3)
So, the tangent line has slope -1/(17√3) and passes through (13/2, 13√3/2). Using the point-slope formula, its equation is
y - 13√3/2 = -1/(17√3) (x - 13/2)
y = -(x - 338)/(17√3)

The tape diagram represents the ratio of the time you spend tutoring to the time your friend spends tutoring. You tutor for 3 hours. How many hours does your friend spend tutoring?
You
Friend
Answer:
15 Hours
Step-by-step explanation:
So you have one block, and your friend has two.
We know that you work for 3 hours, this means that your only block must represent 3 hours.
And all the blocks represent the same amount of time, then each one of the two blocks of your friend also represents 3 hours.
Then in total, he tutored for 3 hours + 3 hours = 6 hours.
Therefore, you still have only one block, but now your friend has 5.
Using the same reasoning as above, we can conclude that each block represents 3 hours, and your friend has 5 of them, this means that he tutored for:
5*3 hours = 15 hours

4x-5y=6 for y
Solve the equation for the specified variable
Answer:
[tex]y = - \frac{4}{5} x + \frac{6}{5} [/tex]
Step-by-step explanation:
First subtract 4x on both sides in order to get -5y alone. Now you have -5y = 4x + 6 (since neither 6 nor 4x are like terms). Now divide -5 on both sides in order to get rid of it, so we can get y by its self. Now you have y = -4/5 x + 6/5

Write the equation in standard form.
y+ 7= -3/2 (x+1)
Answer:
2y + 3x = -17
Step-by-step explanation:
standard form is Ax + By = C
first step is to distribute -3/2 among 'x' and then by 1 to get:
-3/2x - 3/2
you now have y + 7 = -3/2x - 3/2
we want to get the -3/2x term on the same side as 'y' and get 7 from the right side to the left side
we want to add 3/2x to the left side of the equation because it is being subtracted:
y + 3.2x + 7 = -3/2
now we want to subtract 7 to the right side because it is currently being added:
y + 3/2x = -7 3/2
we can convert -7 3/2 to be -17/2
we now can eliminate the denominator of 2 in the 'x' term by multiplying each term by 2 to get:
2(y + 3/2x) = -17/2(2)
distribute and simplify to get:
2y + 3x = -17
