Find the slope of the line passing through each of the following pairs of points and draw the graph of the line.
a
(4, 3), (2, 2)
Answer:
The slope is 1/2
Step-by-step explanation:
Answer: 0.5
Step-by-step explanation:
The equation for finding a slope is y2 - y1/x2 - x1
so 2 - 3 = -1
and 2 - 4 = -2
so -1/-2 whish is 0.5
solve for x

If Ivy makes $50 each week mowing lawns. She estimates that she will
have to spend $120 this summer of gas for the mower. If Ivy wants to
earn $480 this summer, how many weeks must she work?
Answer:
12 weeks
Step-by-step explanation:
The equation is 50*x-120=480
We have to find out what x equals
50*12=600
600-120=480
Your answer is 12.

The yearbook club has 5 members returning from last year. They set up a booth in the cafeteria to recruit more members, and an average of 3 new members sign up each day. Which best describes why the graph relating the total number of members on the yearbook club, m, and the number of days the booth is set up, d, will be continuous or discrete?
The graph will be continuous because an end day for the booth being set up is not given in the description.
The graph will be continuous because there can be any number of people signing up each day since we are only given the average.
The graph will be discrete because some day the number of available people to sign up for the club will run out.
The graph will be discrete because there is no such thing as a partial person to sign up and the booth is set up once each day for sign ups.
The correct option is the graph will be discrete because there is no such thing as a partial person to sign up and the booth is set up once each day for sign ups.
What is Discrete Random Variable?Discrete random variables are defined as the variable which takes only finite number of distinct values in the data set.
These variables are usually countable.
Continuous random variables are those which take infinitely many values in the data set.
These include all set of real numbers.
Here the situation is the recruitment of members for the yearbook club.
The members coming for sign up will only in the form of numbers like 0, 1, 2, 3, ........
There is nothing like partial person coming for the sign up.
And there will be only finite number of members each day because booth is set up only once in each day.
Hence the graph of total number of members on the yearbook club, m, and the number of days the booth is set up, d, will be discrete.

What is the vertex of y=3|x+1|-2
Answer:
(-1,-2)
Step-by-step explanation:
Generally, the absolute value function can be expressed like so:
f(x) = y = a|x-h|+k, where vertex: (h,k)
Rewriting our function here ever so slightly gives us: y = 3|x-(-1)|+(-2)
So the vertex is at (-1,-2)
what does the point where the line intersects the x-axis of the graph represent?
Answer:
the origin.
Step-by-step explanation:
The point of intersection (0, 0) is called the origin. In an ordered pair, the x-coordinate is always listed first and the y-coordinate second. The x-intercept is the point at which a graph crosses the x-axis. The y-intercept is the point at which the graph crosses the y-axis.

find h(4-n), given that h(t)=10-3t
Answer:
h(4 - n) = -2 + 3n
Step-by-step explanation:
h(t) = 10 - 3t
plug in 4 - n for t
h(4 - n) = 10 - 3(4 - n)
distribute the 3 into the parentheses
h(4 - n) = 10 - 12 + 3n
combine like terms
h(4 - n) = -2 + 3n

Answer:
5.39
Step-by-step explanation:
if you are trying to find MN then it means you need to find the length.
we cant use slope, but we CAN make it a triangle!
*see the attached image*
we can use A^2+B^2 to get what the hypotenuse is or C^2 is
2^2+5^2
4+25=29
the square root of 29 is 5.385
then we just round to the hundreth!

What is a line segment?A line section that can connect two places is referred to as a segment.
In other words, a line segment is just part of a big line that is straight and going unlimited in both directions.
The line is here! It extends endlessly in both directions and has no beginning or conclusion.
The distance between two coordinates (x₁,y₁) and (x₂,y₂) are given by
[tex]d = \sqrt {\left( {x_1 - x_2 } \right)^2 + \left( {y_1 - y_2 } \right)^2 }[/tex]
So,
d = [tex]d = \sqrt {\left( {-1 - 4 } \right)^2 + \left( {3 - 0 } \right)^2 }[/tex]
d = [tex]\sqrt{34}[/tex]
d = 5.83 units.
Hence "The value of MN for the given graph will be 5.83 units".

Owen is an alien who only wears fractions of socks at a time. if only 4/5 of owens sock are clean, and he wears 2/5 socks a day, how many days has it been since he washed all his socks? simplify your answer and write it as a proper fraction or as a whole or mixed number
Answer:
[tex]\dfrac{1}{2}[/tex] day
Step-by-step explanation:
Given that:
Owen who is an alien has only 4/5 of his socks clean.
and he wears 2/5 socks a day.
Out of his total 4/5 clean socks.
It will take him (4/5 ÷ 2/5) days to wash all his socks
i.e
the numbers of days since he washed all his socked is:
= [tex]\dfrac{4}{5} \div \dfrac{2}{5}[/tex]
= [tex]\dfrac{4}{5} \times \dfrac{5}{2}[/tex]
= [tex]\dfrac{1}{2}[/tex]
