Answer:
Step-by-step explanation:
Typically in a line the y intercept is the point where your graph crosses the y-axis, and the x value is 0 so (0,b) is the y-intercept where y-intercept is b
The slope can be found by finding the rate of change, so the change in y / the change in x
You can also calculate the slope with 2 points so (x1, y1) (x2, y2)
you take the y values and subtract them, then divide by the x values like this:
y2 - y1 / x2 - x1
If a line is going up to the right in Quadrant I then the slope is positive, if the slope of the line goes down in Quadrant IV then the line slope is negative
Slopes of horizontal lines are zero, the slope of a vertical line is undefined
We use the letter m to stand for the slope

Han creates a scatter plot that displays the relationship between the number of items sold, x, and the total revenue, y, in dollars.
Han creates a line of best fit and finds that the residual for the point (12, 1,000) is 75. The point (13, 930) has a residual of -40.
Interpret the meaning of -40 in the context of the problem.
Answer:
In context of the problem, -40 means that 40 was the difference between the actual data, and the estimated data.
Step-by-step explanation:
Here -40 represent the difference between the actual data and the estimated data.
Given that,
Han creates a line of best fit and finds that the residual for the point (12, 1,000) is 75. The point (13, 930) has a residual of -40.Based on the above information we can say that the -40 shows the difference of data.

What is the y-intercept of y=2x-5 ?
Answer:
the y intercept is -5
Step-by-step explanation:
because the equation is y=MX+b
Answer:
The y-intercept is -5.
Step-by-step explanation:
[tex]y=2x-5[/tex]
The equation is in slope intercept form.
[tex]y = mx+b\\\\m - \text{Slope}\\\\b - \text{Y-intercept}[/tex]
Since ' -5 ' is in 'b' 's place, it is the y - intercept.

In right triangle angles L and M are complementary find the measure of angle L
Answer and Step-by-step explanation:
90 - 51 = 39.
Angle L is equal to 39, since angle M is equal to 51.
The angles are complementary, so they add up to 90, which is why we subtract 51 from 90 to get 39.

What is the Y-Intercept of this table?
[tex]\left[\begin{array}{ccc}x&y\\5&16\\6&19\\7&22\end{array}\right][/tex]
Answer:
The Y-intercept is 4 or (0,4) in a plot
Step-by-step explanation:
To find the Y-intercept you need to make the "x" zero so if you move 5 to 4 in the "x" plot you need to move 16 to 13
(Since 22 to 19 is -3 19 to 16 is -3 as well it is safe to say that the next number is 13)
Now continue until you reach 0 in the "x"
4 to 3 and 13 to 10
3 to 2 and 10 to 7
2 to 1 and 7 to 4
So the y-intercept is 4 or (0,4) in a plot

The cost of renting ice skates at a skating is $1.25. The rink charges $3.25 for each hour, x, of skating. Which graph best models this situation, where y is the total cost to go skating?
Answer:
Step-by-step explanation:
y = 3.25x + 1.25
1.25 is y-intercept
3.25 is the slope of a graph.
If x = 0, then y = 1.25
(0, 1.25)
If x = 3, then y = 3.25(3) + 1.25 = 11

Larger number:
Smaller number:
Answer:
larger number = 28
smaller number = 14
Step-by-step explanation:
42/3 = 14
14 x 2 = 28
to check ur answer u could add them together so they equal 42
14 + 28 = 42
Answer:
Larger number : 28
Smaller number : 14
Step-by-step explanation:
a + b = 42
a = 2b
2b + b = 42
3b = 42 (divide both sides by 3)
b = 14
a = 2 x 14
a = 28

The total cost of renovation depends on labor and materials. You decide to budget $25,000 towards labor. The amount, A, that each worker earns varies inversely to the number of workers on the job, n.
1) complete the table to indicate the amount earned for the given number of workers.
2) what do you notice about the product, A*n?
Answer:
see attachedA*n is the constant 25000Step-by-step explanation:
1)The amount A is said to vary inversely with n, so the equation relating the two is ...
A = k/n
The value of k can be found by multiplying this equation by n:
k = nA
Using values from the first line of the table, we find ...
k = (1)(25000) = 25000
So the relation we need to use to fill the table is ...
A = 25000/n
The filled table is attached.

2)As we saw in part 1, the product A*n is the constant of proportionality. It is a constant.

a polynomial contains number of terms
Correct question is;
A polynomial contains _____ number of terms
Answer:
(n + 1)
Where n is the degree of the polynomial
Step-by-step explanation:
Now, for a polynomial that has degree of n = 1, the number of terms it will have is 2.
Similarly, a polynomial that has degree of n = 2, the number of terms it will have is 3.
This means from the above, we can deduce that the number of terms in a polynomial with degree "n" is n + 1.
We can therefore conclude that a polynomial can have any finite number of terms as n + 1

Salesclerks at a store are giving away candles. There are 12 candles on a tray. Three are white and two are red. The rest are green or blue. When choosing a candle at random from the tray, a customer is as likely as not to select a green candle. What tis the likelihood that the customer will select a blue candle? Tell whether it is impossible, unlikely, equally likely as not or certain. Explain your answer.
Answer:
one blue candle. 1/12 probability.
Step-by-step explanation:
if they are as likely as not to select a green candle, then there are 6 green ones. so now we have accounted for 11 if I am right, so only one can be blue
It is equally likely as not that the customer will select a blue candle.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
Let the number of green candles on the tray be G, and the number of blue candles be B.
We know that there are 12 candles in total on the tray, so:
G + B = 12 (total number of green and blue candles is 12)
G/(G+B) = 1/2 (as the probability of selecting a green candle is equal to the probability of selecting a non-green candle)
We can use these two equations to solve for G and B:
G + B = 12
G = (12 - B)
Substituting into the second equation:
(12 - B) / (12 - B + B) = 1/2
(12 - B) / 12 = 1/2
12 - B = 6
B = 6
So there are 6 blue candles on the tray.
Since there are 12 candles in total, and 6 of them are blue, the probability of selecting a blue candle at random is:
P(selecting blue) = B / (G + B) = 6 / 12 = 1/2
Therefore,
It is equally likely as not that the customer will select a blue candle.
This means that the probability of selecting a blue candle is 50-50, which is neither impossible nor certain, but rather equally likely as selecting a green candle.
