How do you calculate slope in pre algebra
Answer:
Find the slope from a graph
Locate two points on the line whose coordinates are integers.
Starting with the point on the left, sketch a right triangle, going from the first point to the second point.
Count the rise and the run on the legs of the triangle.
Take the ratio of rise over run to find the slope. m = rise / run.
Inverse operations are mathematical operations that undo one another. Division is the inverse operation of multiplication. -2 × 6 = -12. -12 ÷ 6 then "undoes" this multiplication, leaving us with a quotient of -2. Multiplication and division follow the same rules related to signs. A negative integer multiplied by a positive integer gives us a negative product. Similarly, a negative integer divided by a positive integer gives us a negative quotient. However, unlike multiplication, division is not commutative. If you change the order of the number you're dividing and the number you're dividing by, you will get a different quotient. Find the quotient: -54 ÷ 9 =
Answer:
-54/9=-6
Step-by-step explanation:
When doing this division we need to take a couple of things into account. First, notice we are dividing a negative number into a positive number, therefore our answer must be negative.
Second, notice that 9 fits 6 time into 54, therefore:
-54/9=6
We can look at this graphically, if we have 54 squares and divided them in groups of 9, we would get 6 groups of 9 in total.

33 is 90% of what number? Round to the tenths place.
Answer:
36.7
Step-by-step explanation:
Since 33 is 90% of a number, you can divide 33 by 9 to get 3 2/3. This 3 2/3 is 10% of the number, so multiply 3 2/3 by 10 to get 36 2/3. 36 2/3 rounded to the nearest tenth is 36.7, so there's your answer. Hope it helps!
If you are in a store and there is a discount sale u buy something and the original price was $45 and the discounted price was $18 what was the discount?

whats 3(x + 2) = 21?
show work please !!
Answer:
x=5
Step-by-step explanation:
[tex]3(x+2)=21[/tex]
[tex]3x+6=21[/tex]
[tex]3x+6-6=21-6\\\\3x=15\\\\\frac{3x}{3} = \frac{15}{3} \\\\x=5[/tex]
Answer:
x = 5
Step-by-step explanation:
You first have to multiply 3 by x and 2, and you would get 3x and 6. 3(x + 2)=3x +6
Then you have to move the 6 to the other side and it will become negative. 3x= -6 +21
Then you subtract 21-6 to get 15. 3x = 15
Then you are left with 3x = 15.
Divide 3 from both sides and you get x =5.

Beth is putting up a fence in her yard so her dog can play outside. She purchased 80 feet of fencing. If the fenced area is a rectangle with a width of 30 feet, what is the length of the fenced area?
Answer:
10 feet
Step-by-step explanation:
The formula for the Perimeter fo a rectangle
= P = 2L + 2W
Where:
L = Length
W = Width
From the question
P = 80 feet
W = 30 feet
Hence:
80 = 2L + 2(30)
80 - 2(30) = 2L
80 - 60 = 2L
20 = 2L
L = 20/2
L = 10 feet
Hence, the length of the fenced area = 10 feet

How do you find the equation of the circle given center at (1,-3), and radius 10?
Answer:
note: all the twos are to the power100=(x−1)2(y+3)
Step-by-step explanation:
Suppose the centre of the circle was at the origin (where the x axis crosses the y axis). Then the equation would be:
r2=x2+y2
The reason for this format is that the length of the radius (which is of fixed length) can be related to x and y by Pythagoras. However, the circle centre is not at the origin. It is at
(x,y)→(1,−3)
So we can mathematically make this work by 'theoretically' moving the actual centre to a new centre located at the origin.
Thus we would have:
r2=(x−1)2+(y−(−3))2
r2=(x−1)2+(y+3)2
But the radius is 10 so we have
(10)2=(x−1)2+(y+3)2
100=(x−1)2+(y+3
Which transformation maps B (2,5) to B'(-2,-5)?
A. A 90 degree rotation
B. Reflection about the y-axis
C. A 270 degree rotation
D. A 180 degree rotation
Answer: B
Step-by-step explanation: Because the positive numbers changed to negatives meaning that it flipped over an axis and since both of them changed it would be the y-axis
A company has two manufacturing plants with daily production levels of 7x + 19 items and 2x - 7 items, respectively. The first plant production how many more items daily than the second plant? The first plant produces __? More items daily than the second plant.
Answer:
The first plant produces 5x + 26 more items daily than the second plant
Step-by-step explanation:
First plant = 7x + 19
Second plant = 2x - 7
The first plant production how many more items daily than the second plant?
Subtract items produced by the second plant from items produced by the first plant
= 7x + 19 - (2x - 7)
= 7x + 19 - 2x + 7
= 5x + 26
The first plant produces 5x + 26 more items daily than the second plant.

==============================================================
Explanation:
Check out the diagram below
In that diagram, I've marked the highest and lowest bars with red ink.
max = 8.4 inchesmin = 0.8 inchesThe range is simply the difference of the highest and lowest values
So,
range = max - min
range = 8.4 - 0.8
range = 7.6

joe spent $15. he bought 2 cans of oil. abouthow many gallons of gasoline did he buy
The expression that can be used to determine the total amount of Joe spent on gasoline and oil is 2.85g + 3.15c.
The number of gallons of gasoline he bought is 3.0 gallons.
How to find the expression to determine the total amount of gas bought?Joe bought g gallons of gasoline for 2.85 dollars per gallons and c cans of oil 3.15 dollars per can.
Therefore, the expression that can be used to determine the total amount of Joe spent on gasoline and oil is as follows:
total amount = 2.85g + 3.15c
where
g = number of gallons of gasolinec = cans of oilJoe spent 15 dollars . He bought 2 cans of oil . The amount of gallons of gasoline he bought can be calculated as follows:
15 = 2.85g + 2(3.15)
15 = 2.85g + 6.3
15 - 6.3 = 2.85g
8.7 = 2.85g
g = 8.7 / 2.85
g = 3.05263157895
Therefore,
g = 3.0 gallons of gasoline
