Answer:
The operation would be marked as undefined
Step-by-step explanation:
Many people don't feel comfortable using negative numbers so find the absolute values of both numbers.
|-10| = |-20| to 10 = 20
Since 10 is not equal to 20, it is undefined
-----------------------------------------------------------------------------------------------------------------
Just in case
If you meant (-10)x = (-20) Then do this:
-10x = -20
/-10 /-10 Divide by -10 do get x
A negative divided by a negative makes the answer positive.
-20/-10 = 2
x = 2
The cost to park for the first day is = $15
Cost to park for each subsequent day = $ 10
Let the number of days be represented by = n
Let the parking cost be denoted by function = p(n)
So, out of all the given options,
Option 4th is correct.
p(1) =15; p(n)=p(n-1) +10 for n≥2
Explanation:
Put n=2
=
Hence, day 1 fee is $15 and day 2 fee is $10 so total is = $25
Option 6th is correct.
p(n) = 10n+5
Explanation:
Total cost is represented as =
=
=
=

V of triangular prism= 15•8=120
Answer:
The equation of parabola is standard form is
Step-by-step explanation:
Given equation of parabola is,
In order to find the equation of parabola in standard form, eliminate x from left side of equation and use completing square method to find the equation.
First step is to add x on both side of equation.
Rewriting,
Now applying completing square method as follows.
Following are the steps for calculation of this method.
Find the last term of above equation by using below formula,
Now coefficient of y is 8.
Simplifying,
Second step is to add and subtract the last term.
Rewriting,
Since
Using above formula,
Therefore, the equation of parabola in standard form is
