DEF is congruent to D’E’F’ because DEF is the same shape and size as D’E’F’
The first thing we have is the following equation:
54 ÷ 9 = 6
Let's multiply both sides by 9 to not alter the equality:
(54 ÷ 9) * 9 = 6 * 9
Rewriting we have:
54 = 6 * 9
Answer:
An inverse operation that would be used to verify the equation is:
D. 9 × 6 = 54
Answer:
The required equation is 
.
Step-by-step explanation:
Consider the provided information.
The Initial value of poster = $ 18
After 1 year amount of increase = $ 20.70
With the rate of 15% = 0.15
Let future value is y and the number of years be x.
Now verify this by substituting x=1 in above equation.
Which is true.
Hence, the required equation is .
Answer:
y-2=2(x-1)
Step-by-step explanation:
Pick any two points from the line (example: (1,2) and (2,4))
Find the slope of them
Reminder: Slope is changes in y/changes in x or y2-y1/x2-x1
In this case, m= 4-2/2-1 which is 2
Now to use slope point form, chose any point and substitute it into this equation:
y-y1=m(x-x1)
Substituting it would get
y-2=2(x-1)
Or
y-4=2(x-2)
