The correct answer among the given choices is the first one:
“A graph shows Time in hours on the x-axis and Aida’s Distance from Tent
in miles on y-axis. The graph shows three straight lines. The first straight
line joins ordered pairs 0, 0 and 2, 4. The second straight line joins ordered
pairs 2, 4 and 8, 4. The third straight line joins ordered pairs 8, 4 and 9, 0.”
The given ordered pairs is in the format of (t, d) where t is time and
distance is d. Time will always be on the x-axis since it is always an
independent variable.
The first ordered pair should be (2, 4) since it took her 2 hours to
trek to the hilltop. From the given choices, only the 1st and 3rd
choice has this first ordered pairs so we are down to two choices.
Now the second ordered pair should be (8, 4) since she spent 6 hours at
the top but no change in distance. And only the 1st choice has this
value therefore it is the answer.
To write a percent that is less than one, you could use a decimal and write a percentage symbol by it OR you could have a number that represents half of one, like 50% of 1.
Growth factor is identified as the factor by which the quantity multiplies itself over time.
Sales tax = 10.5%
Sales price = 100%
Growth factor = 100% + 10.5% = 110.5% or 1.105
The growth factor for any item purchased at your local circle mart is 1.105.
Answer:
a+9 = b
Step-by-step explanation:
a=b-9
Add 9 to each side
a+9=b-9+9
a+9 = b
Start by taking out a common factor.
x^10
x^10(x^6 - 2x^5 - x^4 + 4x^3 - x^2 - 2x + 1) = 0
So far we know that D won't work.
x - 1 is a factor because putting 1 in for the xs in the expression inside the brackets gives 0 Now you need to do a division. I'm going to assume you can do that.
Using division, I get
x^5 - x^4 - 2x^3 + 2x^2 + x - 1 Now divide x - 1 into this mess again. You get
x^4 - 2x^2 + 1 which factors into
(x^2 - 1)(x^2 - 1) which factors into
(x - 1)(x + 1)(x - 1)(x + 1) = 0
The first two divisions add (x -1)(x - 1)
========================
So we have (x - 1) with a multiplicity of 4 and (x + 1) with a multiplicity of 2
or x = 1 with a multiplicity of 4 and x = -1 with a multiplicity of 2 and x = 0
with a multiplicity of 10
That's the answer.
