Which graph represents a line with a slope of - į and a y-intercept equal to that of the line y = = x-27
ТУ
Answer:
Step-by-step explanation:
Let the equation of the line is,
y = mx + b
Where m = slope of the line
b = y-intercept
Slope of the line 'm' = -[tex]\frac{2}{3}[/tex]
y-intercept 'b' of the line is equal to the y-intercept of another line given as,
[tex]y=\frac{2}{3}x-2[/tex]
Here y-intercept of the line 'b' = -2
Therefore, the equation of the line will be,
y = (-[tex]\frac{2}{3}[/tex])x + (-2)
[tex]y=-\frac{2}{3}x-2[/tex]
Here negative slope represents a line which is decreasing having y-intercept = -2

Noah and Diego left the amusement park’s ticket booth at the same time. Each moved at a constant speed toward his favorite ride. After 8 seconds, Noah was 17 meters from the ticket booth, and Diego was 43 meters away from the ticket booth.
Q: Which line represents the distance traveled by Noah the blue line or the black line?
Answer: Black
Step-by-step explanation: I feel like the higher the line is on the graph, the farther they have moved, so since the black line is the lowest, it might be Noah.

A researcher studying koi fish collected data on three variables, A, B, and C. The following residual plots show the residual for a model for predicting each variable from the age of the fish
Answer:
Plot for Variable C Only
Step-by-step explanation:
Trust me, unless your teacher switched the order of the charts in which case it's the linear one!
The residual plot is a form of scatter plot that shows the difference between the observed value and the actual value.
The plot that supports a linear model is plot A.
The complete question requests that we select all plots that can be used as a linear model.
For a residual plot to be used as a linear model, the pattern of the residual plot must be at random (i.e. it must not show any obvious pattern)
From the given plots (see attachment), we have the following observation.
Plot A shows no patternPlot B shows a curve (like a quadratic function)Plot C shows a linear patternHence, only plot A can be used as a linear model.

Which describes a type of tax that funds city programs? Oprogressive tax federal income tax Olocal income taax Omedicare tax
Answer:
local income tax
Explanation:
The "local income tax" refers to the tax levied to people who are residing or working in a specific local area. This is the tax being used to fund the city programs that will help improve the community.
Such programs include the development of parks in the area, including landscape beautification or enhancement of the public markets, improvement of public schools, etc.
Local income tax may appear as a "withholding tax" in some situations. In this case, it is automatically being withheld from the wage of a worker.

A battery was charged. When the charging began, it was 232323 percent full. After 303030 minutes of charging, the battery was 898989 percent full. How long did it take the battery to be fully charged?
Answer:
1,172 minutes
Step-by-step explanation:
Answer:
35 minutes
Step-by-step explanation:
Let's say that the percentage of the battery's capacity that is charged increases by VVV percent each minute. Then, it increases by V\cdot TV⋅TV, dot, T percent in TTT minutes. In addition, we know that when the charging began, the battery was 232323 percent full.
The percentage of the battery's capacity that was charged at any given time is found by taking the percentage the battery was already charged when the charging began and adding to it the percentage that was additionally charged since then. We can express this with the equation C=23+V\cdot TC=23+V⋅TC, equals, 23, plus, V, dot, T, where:
CCC represents the percentage of the battery's capacity that is charged at a given time
VVV represents the charging rate (in percent per minute)
TTT represents the time (in minutes)
Hint #22 / 4
We know that after 303030 minutes (T=\blue{30})(T=30)left parenthesis, T, equals, start color #6495ed, 30, end color #6495ed, right parenthesis, the battery was 898989 percent full (C=\pink{89})(C=89)left parenthesis, C, equals, start color #ff00af, 89, end color #ff00af, right parenthesis. Let's plug these values into the equation to find the value of VVV.
\qquad \begin{aligned}\pink{89}&=23+V\cdot\blue{30}\\ 30V&=66\\ V&=2.2\end{aligned}
89
30V
V
=23+V⋅30
=66
=2.2
Therefore, the battery was charged at a rate of 2.22.22, point, 2 percent per minute.
Hint #33 / 4
To find how long it took the battery to be fully charged, we can plug C=100C=100C, equals, 100 into the equation and solve for TTT.
\qquad\begin{aligned}100&=23+2.2T\\ 2.2T&=77\\ T&=35\end{aligned}
100
2.2T
T
=23+2.2T
=77
=35
Hint #44 / 4
The battery was charged at a rate of 2.22.22, point, 2 percent per minute.
It took the battery 353535 minutes to be fully charged.

Is the difference between a rational number and an irrational number always an irrational number ?
Answer: Of course!
Step-by-step explanation: I will suck at explaining this. Here's the general idea: A rational number is a number that is the quotient of two integers, or whole numbers. Rational numbers are things like 2, 5, 6, 2.5, 2.25, 6.53465, 1.666666666666666666666666666667; you get the idea. The point is, it can be represented by the fraction of two integers. An irrational number is something that cannot be represented this way. It's the same thing with multiplying an even number by an odd number; it'll always be odd, regardless of what the odd number is. Same with odd - even; it'll always be odd. Point being, there is no rational number that can be subtracted by an irrational number and be rational, or an irrational number that is subtracted by a rational number.

PLS HELP:( !! What is an equation of the line
that is perpendicular to the line
y= -2/3x-1 and passes through
the point (-4, 2)?
Answer:
[tex]y = \frac{3}{2} x + 8[/tex]
Step-by-step explanation:
The given equation is written in the form of y=mx+c (where m is the gradient and c is the y-intercept).
Thus, gradient of given equation= -⅔
The products of the gradient of perpendicular lines is -1.
(Gradient of line)(-⅔)= -1
Gradient of line
[tex] = - 1 \div ( - \frac{2}{3} ) \\ = \frac{3}{2} [/tex]
Hence, m= [tex] \frac{3}{2} [/tex].
Subst. m= [tex] \frac{3}{2} [/tex]into the equation:
[tex]y = \frac{3}{2} x + c[/tex]
To find the value of c, substitute a pair of coordinates into the equation:
When x= -4, y= 2,
[tex]2 = \frac{3}{2} ( - 4) + c \\ 2 = - 6 + c \\ c = 2 + 6 \\ c = 8[/tex]
Thus, the equation of the line is [tex]y = \frac{3}{2} x + 8[/tex].

Which of the following statements are true?
Choose all answers that apply:
Based on the equation of the line, the true statements are:
The slope of the line is 2.5.A change of 2 units in x results in a change of 5 units in y.Why are these true?The formula of the line from the original question is y = 2.5x.
The equation of a line is given as:
y = mx + c
M in the above equation is the slope of the line. In the above line, the format is:
y = 2.5x
Even though c is not present, m is present as 2.5 which makes it the slope of the line.
A change in 2 units in x would be:
= 2 x 2.5
= 5 units in y

1. In the equation y = 2x, what would be the C.O.P ?
2. A graph has the points (2,6) ; (3,9) ; and (5,15)
What is the equation of the graph?
9514 1404 393
Answer:
the contant of proportionality is 2y = 3xStep-by-step explanation:
1. Match the given equation (y = 2x) to the pattern ...
y = kx . . . . . k is the constant of proportionality
Hopefully, you can see that k corresponds to 2. That is, the coefficient of x is the constant of proportionality. It is 2.
__
2. Since you're studying proportions, it is useful to look at the ratio of the y-value to the x-value. In each case, it is 6/2 = 9/3 = 15/5 = 3. Then the graph shows the variables are proportional, with a constant of proportionality of 3.

Compute the answers for this fish tank containing water.
Compute the mass of water filling this tank.
0.25 g
20 g
250 g
Answer:
Option (3)
Step-by-step explanation:
Since density on an element = [tex]\frac{\text{Mass}}{\text{Volume}}[/tex]
Volume of the water in the aquarium = volume of the aquarium
= Length × width × height
= 10 × 5 × 5
= 250 cm³
We know density of the water = 1 gram per cm³
By putting these values in the formula,
1 = [tex]\frac{\text{Mass}}{250}[/tex]
Mass = 250 g
Therefore, Option (3) will be the answer.
