I’m not sure if this may be to hard of a method for you depending on which grade you are in but I’ll try and explain the best I can.
Use the formula:
Y2 - Y1
————
X2 - X1
Take two points from the line: (10,30) and (40,50)
Only because they have exact values
(10,30) and (40,50)
The 10 is X1 because it’s the x of the first coordinate. 30 is Y1 for the same reason
The 40 is X2 because it’s the X of the second coordinate. 50 is the Y2 for the same reason
Substitute this into the formula
50-30
———-
40-10
= 20
—-
30
Which simplifies to 2
—
3
So the slope of the line is 2
—
3
I hope this helps.
Answer: 350 cubic inches
Step-by-step explanation:
Given:
length = 10 inches
width = 7 inches
height = 5 inches
To find the cubic inches the shoe box will be means that we are finding the volume.
The formula for finding the volume of a cuboid is given as :
Volume = length x width x height
Therefore:
Volume = 10 x 7 x 5
Volume = 350 cubic inches
First, you divide 18 by 3. When you have the quotient, you recall that the two original numbers had opposite signs, and so you label the answer negative.
Set up an system:
x+y=52
x=y-2
Substitute in:
(y-2)+y=52
2y-2=52
2y=54
y=27
27-2=25
The answers are 27 and 25
