if the line passes through the top left part AND the bottom left part, slope's positive. if it passes through both of the other ones slope is negative. if it's parralell to one of the axis, the answer is undefined or 0, the horizontal one being 0
right away we can see line b's slope is positive, and line d's slope is negative.
y=mx+b
b is the y intercept
m is slope
Solve when m = 7 and k = 2

If the value of a in the quadratic function f(x) = ax2 + bx + c is 4, the function will_______.
A) open down and have a maximum
B) open up and have a maximum
C) open down and have a minimum
D) open up and have a minimum
Answer:C
Step-by-step explanation:
The function will be open up and have a minimum point.
Option D is correct.
Quadratic function:If a quadratic function is given as;
[tex]f(x)=ax^{2} +bx+c[/tex]
When [tex]a > 0[/tex] , then the graph of function will be open up and have a minimum point.When [tex]a < 0[/tex] , then the graph of function will be open down and have a maximum point.Since, It is given that value of a is 4 ,
So that, [tex]a > 0[/tex] . Hence, the function will be open up and have a minimum point.

The graph shows the prices of different numbers of bushels of corn at a store in the current year. The table shows the prices of different numbers of bushels of corn at the same store in the previous year.
A graph shows the Number of Bushels on the x-axis and the Price of Corn in dollars on the y-axis. The x-axis scale is shown from 0 to 14 at increments of 2, and the y-axis scale is shown from 0 to 98 at increments of 14. A straight line joins the ordered pairs 2, 14 and 4, 28 and 6, 42 and 8, 56 and 10, 70 and 12, 84.
Previous Year
Number of Bushels
Price of Corn (dollars)

10

20
6
30
8
40
Part A: Describe in words how you can find the rate of change of a bushel of corn in the current year, and find the value.
Part B: How many dollars more is the price of a bushel of corn in the current year than the price of a bushel of corn in the previous year? Show your work.
Answer:Part A:8 Part B:$1
Step-by-step explanation:
Part A: 7 dollars
- The graph shows that 2 bushels is 14 dollars, because the graph has a straight line, the rate remains constant you must divide the sides by two to find the amount for one bushel which would be 7 dollars.
- And to double check you would divide 28 by 4, 42 by 6, 56 by 8, 70 by 10, 84 by 11, and 98 by 12. they all equals 7 dollars So, the equation would be y = 7x.
- 7 can be known as the slope and rate of change.
Part B:2 dollars
- The years before show 2 bushes was 10 dollars
-so you would divide 10 by two you would get five To double check you would do the same thing with 20 by 4, 30 by 6 and 40 by 8, and they all equal 5 dollars.
-if you use this answer be sure to reword it so you dont get copy write and integrity. have a great day or night.

A bus left Town A at 10:00 am, driving at an average speed of 70 mph. At 12:15 am, the truck reached Town B.
a) What is the distance between Town A and and Town B?
b) How long would it take the truck to drive from Town B to Town A at an average speed of 50 mph?
Answer:The important formula to this problem is or
Now, the speed of the car is 70 km/h, and the speed of the truck is 50 km/h. It will take the two vehicles the same amount of time to meet since they both left at the same time. So, since distance equals rate times time, and t = time:
the distance of the car = 70t
the distance of the truck = 50t
Because they both left in opposite directions, and the towns are 420 kilometers apart, the equation for this would be
We now solve the equation.
It will take the vehicles 3 and a half hours to meet. Since we're looking for the time, 3 and a half hours from 10:00 AM is 1:30 PM.
So, the car and the truck will pass each other at 1:30 PM.

Sara’s boss informed her she is getting a 5% raise. She currently makes $22 per hour. What is her new hourly wage?
Use your plan of multiplying 5100 and $22. What is the amount of Sara's raise?
Answer:
Her new hourly wage will be $23.10
Step-by-step explanation:
First, let's find out how much her raise is in dollars.
0.05 x 22 = 1.10
Then, let's add that to her current wage.
1.10 + 22.00 = $23.10
Hope this helps! Have a great Monday!
Answer:
Her new hourly wage will be $23.10
Step-by-step explanation:
5/100 * 22= 1.1
1.1 + 22= 23.1

How do you write 118% as a fraction, mixed number, or whole number?
118% as a fraction is 118/100, mixed number as 1 9/50.
What is mean by Fraction?A fraction is a part of whole number, and a way to split up a number into equal parts. also number which is expressed as a quotient is called fraction that can be written as the form of p : q, which is equivalent to p / q.
We need to find the fraction 118% as a fraction, mixed number, or whole number.
Since we know that Fraction
= 118/100Therefore,
Mixed number = 1 18/100 or 1 9/50
When the numerator is less than the denominator, then the fraction is called proper fraction, it is called improper fraction that proper fraction is also called fraction which is less than 1.
Therefore the answer is; 1 9/50

Answer:
quadrilateral, 3
Step-by-step explanation:
I think you put the grocery store at the wrong location. You graphed point (-1, 1) while it should be at (1, -1) (i.e. one to the right then one down)
The figure drawn by 4 points on a plane (assuming no 3 points lie on the same line) is a quadrilateral
The school is at (-2, -1) while the grocery store is at (1, -1). A straight line connecting them is a horizontal line of length 3, so the two points are 3 apart.
It is possible to find the distance between the points you actually drew, but I suspect that is a bit in the future for you.

This is a random question but what are tips on studying or in other words how to study. I have a very bad problem with procrastination I do stuff like talking on discord or draw instead of doing my schoolwork how can I fix this and have a more sustainable studying habits. I have trouble in areas such as Math and English.
Answer:
Some of the steps I take to having a more productive schedule is to plan time to study if you have a phone or calander set alarms to help you know when it is time to study and set multiple f them so if you dont get motivated the first time you will have other reminders to keep going.Dont plan any rediculous amounto of time either you can ake half an hour or fourty five minutes out of your day without feling stressed by the amount your doing.Find fun ways to study just plain old reading of chapters can seem redundant find resources online to help you such as Quiizlets and practice test those things are easy to come across and if you are havng a hard time staying concentrated by yourself study with a freind or ask a parent or sibling to help
