A line is represented by the equation y/x−2=3/11 . Select all the coordinates of points that lie on the line.
A. (−163, −2)
B. (0, 2)
C. (5, 911)
D. (0, 611)
To determine the answer, we must graph each point and the line.
According to this graph, the point that lies on the line is B. (0, 2).
*Note: the line shown on the graph is [tex]y = \frac{3}{11}x + 2[/tex], which is the equivalent of the one in the question. All I did was solve the equation for y to convert it to slope-intercept form.

A political polling agency predicts candidate A will win an election with 54% of the votes. Their poll has a margin of error of 4% both above and below the predicted percentage. Which inequality represents the predicted possible percent of votes, x, for candidate A?
50 ≤ x ≤ 58
x ≥ 50 or x ≤ 58
x ≥ 52 or x ≤ 56
52 ≤ x ≤ 56
Try your best but I think the answer is the first one.

Which equation represents a line that has a slope of 3/4 and passes through the point (2;1)?
A;3y = 4x - 5
B;4y=3x - 2
C4y= 3x+5
Answer:
B
Step-by-step explanation:
m = 3/4
x1 = 2
y1 = 1
Using the formula,
y - y1 = m(x - x1)
y - 1 = 3/4(x - 2)
y - 1 = 3x/4 - 3/2
y = 3x/4 -3/2 + 1
y = 3x/4 - 1/2 (×4)
4y = 3x - 2
Therefore, the answer is B
The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
The equation of the line that passes through (2, 1) and 3/4 as its slope.
4y = 3x - 2
Option B is the correct answer.
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
Slope = 3/4
m = 3/4
The point that passes through = (2, 1)
Now,
The equation of the line is y = mx + c.
y = (3/4)x + c
We will take (2, 1) = (x, y) since it passes through the line.
1 = (3/4)2 + c
1 = 3/2 + c
c = 1 - 3/2
c = -1/2
Now,
The equation of the line that passes through (2, 1) and 3/4 as its slope.
y = (3/4)x -1/2
y = (3x - 2)/4
4y = 3x - 2
Thus,
The equation of the line that passes through (2, 1) and 3/4 as its slope.
4y = 3x - 2
Option B is the correct answer.

(ASAPPP) The position of an object at time t is given by s(t) = -2 - 6t. Find the instantaneous velocity at t = 2 by finding the derivative.
Answer:
The instantaneous velocity at [tex]t = 2[/tex] is [tex]-6[/tex].
Step-by-step explanation:
We have the position as the function
[tex]s(t) = -2 - 6t[/tex]
As we know that the velocity is the rate of change of position over time, so it is basically the derivative of the function.
so finding the derivate of [tex]s(t) = -2 - 6t[/tex]
∴ [tex]s'(t)=-6[/tex]
The instantaneous velocity at [tex]t = 2[/tex]
[tex]s'(2)=-6[/tex]
Therefore, the instantaneous velocity at [tex]t = 2[/tex] is [tex]-6[/tex].
Please note that the negative value indicates the direction of movement, in this case, it would be backward.

The sum of two angles is 180 degrees. Their difference is 70
degrees.
What is the measure of the smaller angle?
Step-by-step explanation:
x+y=180
x=180-y------(i)
x-y=70------(ii)
Now,
Putting the value of x in equation (ii)
x-y=70
(180-y)-y=70
180+2y=70
2y=70-180
2y= - 110
y= - 110/2
y= - 55
Again,
x=180-(-55)
x=235
x-y=70
x-(-55)=70
x+55=70
x=70-55
x=15

Researchers randomly choose two groups from 15 volunteers. Over a period of 9 weeks, one group watches television before going to sleep, and the other does not. Volunteers wear monitoring devices while sleeping, and researchers record dream activity. Which type of study method is described in each situation? Group of answer choices a) observational study b) controlled experiment c) survey
Answer: B. Controlled experiment
Step-by-step explanation:
This is a controlled experiment because the variables in the question are manipulated by the researcher. We are told that while one group watches television before going to sleep, the other group does not.
The controllers won't have control over the variables that were used if it was an observational study while for a survey, it has to do with collection of information regarding certain topics or happenings in order to have people's perception on the topic or area of interest.

please help me
Answer:
Meanings of the numbers:
Most numbers represent an amount. Positive numbers represent above zero. Zero is the only number that does not represent an amount. It means nothing. When you go lower than nothing, you are in the negative numbers. Negative numbers represent absent values pretty much.
How I would use them in every day life:
I would use positive numbers to represent... maybe something I'm trying to get at a store. Ex: 4 bananas
I would use negative numbers to... maybe look at the temperature. Ex: -16 degrees Fahrenheit. Negative numbers are in temperature all the time.

What is the solution to the equation 3x + 2(x - 9) = 8x + x - 14?
A.-8
B.-1
C.1
D.8
Answer:
B.) -1
Step-by-step explanation:
Here, 3x + 2(x - 9) = 8x + x - 14 is given
Now, we will solve and we get,
3x + 2(x - 9) = 8x + x - 14
3x + 2x - 18 = 9x - 14
5x - 9x = 18 - 14
-4x = 4
4x = -4
x = -4÷4
x = -1
Thus, The value of x is -1
Hence, Option B is correct

Determine the value of angle ECB
Please help me out!
Answer: ∠ECB = 60°
Step-by-step explanation:
First, find the value of x by adding them up.
x + 3x + 2x = 6x
Since we know that all of the angles create a 180° angle, we can set up a proportion.
6x = 180°
To find the value of x, divide both sides by 6.
6x ÷ 6 = x
180 ÷ 6 = 30
So now the proportion is x = 30.
Now that we now x = 30, we can plug in 30 to the angle measures.
∠DCA = 30°
∠DCE = 90°
∠ECB = 60°
So angle ECB is 60°.

2 The value of y is directly proportional
to the value of x.
If y = 35 when x = 140, what is the
value of y when x=70
Answer:
y = 17.5
Step-by-step explanation:
Given that y is directly proportional to x then the equation relating them is
y = kx ← k is the constant of proportion
To find k use the condition y = 35 when x = 140, then
35 = 140k ( divide both sides by 140 )
0.25 = k
y = 0.25x ← equation of proportion
When x = 70, then
y = 0.25 × 70 = 17.5
Ms. Dangerfield wants to order 980 erasers for her class for the whole school year. Amazon is selling a bag of 250 erasers for a great price! How many bags of erasers should Ms.Dangerfield buy to have enough for her class this school year? You can use a number line to help you solve.
Answer:
4 packages
Step-by-step explanation:
We have to do 980/250.
So after you get that, you would get 3.92. It would not make sense to get 3.92 packages since that isn't possible on Amazon using common sense. Therefore we must round 3.92 to 4 packages.
Answer:
Ms.Dangerfeild should order 4 bags
Step-by-step explanation:
250 times 4 is 1000 so Ms.Dangerfeild will have 20 extra erasers.
Enter the equation of the line in slope-intercept form.
The line passes through (1.4) and (3,18).
The equation of the line is
Answer: y = 7x - 3
graphed equation attached
Step-by-step explanation: Slope-intercept form . y= mx+b
m is the slope, b is the constant, the y-intercept.
First find the slope: rise/run
Rise is the difference in y-values 18-4 = 14
Run is the difference between x-values 3 - 1 = 2
The Slope is 14/2 simplify:
m = 7
Use this calculated slope with values of y and x from either of the given coordinates and calculate b
y = mx + b
18 = 7(3) + b
18 = 21 + b . subtract 21 from both sides 18 - 21 = 21 -21 + b
-3 = b
Put these calculated values for m and b into the slope-intercept equation"
y = 7x - b
