The graph of a linear function is shown on the coordinate grid below.
What are the slope and y-intercept of the linear function shown in the grid?
A) Slope = –0.4, y-intercept = –5
B) Slope = 2.5, y-intercept = –5
C) Slope = –2.5, y-intercept = 2
D) Slope = 0.4, y-intercept = 2
Answers
Answer:
B) Slope = 2.5, y-intercept = –5
Step-by-step explanation:
Given the following points on the grid, (-1.5, -8.75) and (3.5, 3.75), the slope can be calculated as follows using the formula, [tex] m = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
Let,
[tex] (-1.5, -8.75) = (x_1, y_1) [/tex]
[tex] (3.5, 3.75) = (x_2, y_2) [/tex]
[tex] m = \frac{3.75 -(-8.75)}{3.5 -(-1.5)} [/tex]
[tex] m = \frac{3.75 + 8.75}{3.5 + 1.5} [/tex]
[tex] m = \frac{12.5}{5} [/tex]
[tex] m = 2.5 [/tex]
Slope = 2.5.
The y-intercept is the point at which the line intercepts the y-axis. On the graph, the line intercepts the y-axis at y = -5. Therefore, the y-intercept = -5.

find the LCM of 36 45 63 and 80
Answers
36 = 2*2*3*3
45 = 5*7
63 = 3*3*7
80 = 2*2*2*2*5
Then take each unique factor (2, 3, 5, and 7) and raise each the greatest power it has in any of the input numbers (2^4, 3^2, 5^1, 7^1) and multiply them, and that is your answer.

Emily's credit card has arrived and she has a balance of $2,350. She only has enough money to pay off $1500. She knows she will have to pay 8% interest on whatever she doesn't pay off. Which proportion should she use to determine how much interest she will have to pay?
Answers
Answer:
850 × 8/100
Step-by-step explanation:
Balance in Emily's card = $2,350
Amount paid by Emily = $1,500
Therefore, the amount not paid by her = $2,350 - $1500
= $80.
Also, the interest on the amount not paid = 8% = 8/100
Hence, the proportion representing the interest payable by her is represented by;
Proportion = Amount she does not pay off × Interest paid
= 850 × 8/100
Therefore, the required proportion is 850 × 8/100
what could be the domain and range
Answers
the domain is what x values the function takes on,
the range is what y values the function takes on
notice the open circle on (-8, -8) that means that it never actually touches (-8, -8)
however, there is a closed circle on (3, 4)
So, the domain is [tex](-8, 3][/tex]
and the range is [tex](-8, 4][/tex]

Record your answer and fill in the bubbles on your answer document.
Answers
Answer:
12.7 units
Step-by-step explanation:
Formula to get the distance between the two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,
d = [tex]\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]
From the picture attached,
Sherry is at the origin(0, 0) and going to the top (12, 4)
Distance between these points will be,
d = [tex]\sqrt{(12-0)^2+(4-0)^2}[/tex]
d = [tex]\sqrt{160}[/tex]
d = [tex]4\sqrt{10}[/tex]
≈ 12.7 units
Therefore, Sherry has to travel 12.7 units on the ramp.

The amount of Jen's monthly phone bill is normally distributed with a mean of $48 and a standard deviation of $6. Fill in the blanks. 95% of her phone bills are between?
Answers
Answer: About 95% of her phone bills are between $36 and $60.
Step-by-step explanation:
If population is normally distributed , then by Empirical rule about 95% of the population lies within 2 standard deviations from mean.
Given: The amount of Jen's monthly phone bill is normally distributed with a mean of $48 and a standard deviation of $6.
Then, by Empirical rule
About 95% of her phone bills are between $(48 -2(6)) and $(48 +2(6))
i.e. About 95% of her phone bills are between $36 and $60.
Hence, About 95% of her phone bills are between $36 and $60.
