Find the slope of the line from a graph. Will give brainliest!!!
Answer:
2/1 or 2
Step-by-step explanation:
to find the slope you have to calculate the rise over run, do this by picking two spots on the line that go thourgh the corner of a square. then count the amount up the is your rise then the lateral movement, the is your run.
this means the answer is 2/1 that can be simplified to 2.

Kim picked 250 pounds of pears yesterday and 287 pounds of pears today. What is the percentage increase of
amount of peas picked by Rim
Given:
Kim picked 250 pounds of pears yesterday and 287 pounds of pears today.
To find:
The percentage increase of amount of pears picked by Kim.
Solution:
We know that,
[tex]\%\text{ increase}=\dfrac{\text{New value - Initial value}}{\text{Initial value}}\times 100[/tex]
[tex]\%\text{ increase}=\dfrac{287-250}{250}\times 100[/tex]
[tex]\%\text{ increase}=\dfrac{37}{25}\times 10[/tex]
[tex]\%\text{ increase}=\dfrac{370}{25}[/tex]
[tex]\%\text{ increase}=14.8[/tex]
Therefore, the percentage increase of amount of pears picked by Kim is 14.8%.

What is the commutative property? (Please don't copy and paste from go.ogle I need a good explanation)
Answer:
it basically means that the order in how you multiply doesnt matter. so wether u type 5 x 4 or 4 x 5 in ur calculator, you'll get the same answer either way. this works for when you want to multiply and divide, but not when you wanna subtract or divide.
Step-by-step explanation:
its basically a property that says that if you wanna swap the numbers/variables that are on one side of this specific type of equation (multiplication and addition), you can!
Answer:
yooo
Step-by-step explanation:
the communitive property is when you have the same number or same equation but just reverse it. For example, (5x+67) with the communitive property could be (67+5x). Its just the equation you are given but reversed and since they are the same numbers, you will get the same answer either way you do the problem, hope this helps you lol.
In a group of 60 students, 15 liked maths only, 20 liked science only and 5 did not liked any of two subjects. How many of them liked at least one subject?
Answer:
35
Step-by-step explanation:
Given
n (A) = 15
n (B) = 20
Students who do not like any subject = 5
Hence, number of students who would like either both or either of the two subjects = 60-5 = 55
n (A or B) = n (A) + n (B) - n (A and B)
Number of students linking both the subjects
55 - 15-20
= 55-35 = 20
Number of students linking only one subject = 60-20-5 = 35

If it is true that z2 - 6 = 19, then z2 + 6 = ?
can someone please help me? it would mean so much to me. thanks a lot!
Answer:
Maybe -3
Step-by-step explanation:
I am not 100% sure but it is better than nothing,
since 3+3=6 I think after 3 is 6, and after 6 is 9. I think that because the more right the line goes you add 3 to every move. So therefore, 3-3=0, and 0-3= -3

Miss Guydan and her friend Alyssa are collecting food for the local food bank. Their goal is to collect 2100 pounds of food. They start with 400 pounds of food donated by a local grocery store. Their goal is to collect 25 pounds of food per day. Write an equation that represent this situation. Define your variables.
Answer: Required equation: 400+25x = 2100
Variable: x = Number of days to donate 2100 pounds.
Step-by-step explanation:
Let x = Number of days.
y = Total pounds of food donated in x days.
Given: Initial amount of food = 400 pounds
Pounds of food donated per day = 25
Total food = Initial amount of food + (Pounds of food donated per day ) (Number of days)
y = 400+25x
Their goal is to collect 2100 pounds.
2100 = 400+25x [Substitute y= 2100]
Required equation: 400+25x = 2100
Variable: x = Number of days.

Answer: what r u supposed to figure out
Step-by-step explanation:
Answer:
See below
Step-by-step explanation:
Given is the piecewise function.
It has three different pieces.
The first piecef(x) = 2, with x ≤ -2Plot the point (-2,2) and draw a horizontal line to the left from this point
The second piecef(x) = 1/2x + 3, at the interval -2<x≤1Plot two border points at x = -2 and x = 1:
f(-2) = 1/2*(-2) + 3 = 2, point (-2, 2)and
f(1) = 1/2*1 + 3 = 3.5, point (1, 3.5)Connect these two points with a line segment
The third piecef(x) = -7/8x + 35/8, at x > 1Plot two points at x = 1 and x = 5 (5 is an example, it could be anything > 1)
f(1) = -7/8*1 + 35/8 = 28/8 = 3.5and
f(5) = -7/8*5 + 35/8 = 0Connect the two points (1, 3.5) and (5, 0) and extend the line to the right
Remember the point (-2,2) belongs to the first piece and the point (1, 3.5) belongs to the second piece.
