Answer:
no
Step-by-step explanation:
the easiest way to find out is to plot these on a graph
for Diego's function, we will write the total amount of savings (or his goal) = the amount hes saving multiplied by the weeks he saves + the amount he started with
y = 2x + 10 (in blue in attached file)
same with Lin
y = 2x + 50 (in red in attached file)
if the lines cross at any point, then that point on the two lines is the same value of x AND y, otherwise, one or the other is a different value
beings as these two lines have the same rate of change, they will not cross, meaning that neither will have the same amount if the rate continues
Hundreds thousands comes after. Hope that helps!
Answer:
5.25
Step-by-step explanation:
So lets gather our information(Note that I use x as the small x value and X as the larger and missing value)
First off, we know that x is 3.
We know that the X value is a scale of x by 1.75.
We can think of this as 1.75x.
So to find X, we can multiply x by the scale 1.75:
x*1.75=X
plug in the value we know for x:
3*1.75=X
=
<u>5.25=X</u>
<u>So our answer is 5.25!</u>
Hope this helps! :)
Answer = x^15
Because if indices are in brackets you just multiply them together ie 3 x 5
You must evaluate each of these options one by one:
A. A $55 jersey with 5% (.05) tax would equal 55 x (1+.05). This equation basically adds on 5% to the original $55. This equals $57.75
B. You can calculate this similarly to above, because it is asking you to add 10% on to the original $57. This would be 57 x (1+.10) = $62.70
C. This is clearly not an option because the original price of the jersey is already more than what Dave has.
D. This is asking you to deduct 25% of the original cost off of $85. You find this similarly to above, but this time you deduct 25% from the 1 --> 85 x (1 - 0.25) = $63.75
So you can see that Dave can only afford option A. Does that make sense?
