Answer:
Step-by-step explanation:
The question is asking you to graph the equations.
The equations are in slope intercept form so y=mx+b
M is the slope and b is the y-intercept
First draw the y & x axis and label/number them
The y-intercept for the first equation is -1 so draw a dot on the -1 on the y-axis
The slope is 2/5 and you use rise/run to continue the slope.
you rise 2 on the y-axis and go right 5 times on the x-axis (for a negative number you go left/down)
For the second equation, you have to turn it into slope intercept form.
You should get y=2/3x+3
You graph this equation the same as you did the first one.

Answer:
61 + n = 82
Step-by-step explanation:
So the total number of candy is 82. This is the sum of each type of candy, i.e. 18 + 24 + 19 + n. So we have
18 + 24 + 19 + n = 82
61 + n = 82
( if we solve the equation we get n = 82 - 61 = 21)

Answer:
Area = 40mm
Example:
The below-solved example problem may be useful to understand how the values are being used in the mathematical formulas to find the trapezoid area.
Example Problem :
Find the area of a trapezoid having the bottom length a = 15 cm, top length b = 12 & height h = 9 cm?
Solution :
The given values
bottom length a = 15 cm
top length b = 12 cm
height h = 10 cm
Step by step calculation
formula to find area = ((a + b)/2) h
substitute the values
= ((15 + 12)/2) x 9
= 121.5 cm2
Answer:
126
Step-by-step explanation:
n! / (r! (n-r)!)
In this case n = 9 and r = 4
9!/ (4! * (9-4)!)
9!/ (4! * 5!)
= 126
9! = 9x8x7x6x5x4x3x2x1
