Answer:
Step-by-step explanation:
1) 5+2*1-3+8 = 5+2-3+8 = 7-3+8 = 4+8 = 12
2) 2+5*1 = 2+5 = 7
Answer:
there is no solution
Step-by-step explanation:
1st switch sides: -x2+2x+1=0
2nd add similar elements: -2x + 2x = 0
1 = 0
Thus, this equation has no solution
hope i helped :)
The function that best fits the graph points is; B: y = 65.0778 * 772.9605ˣ
<h3>How to Interpret Function Graphs?</h3>
From the given graph, we can see that is parabolic form and as such we can say it is an exponential function.
Looking at the options, only option B is in exponential form and as such, we will take one point on the graph to check if this is the right function.
Let us use the coordinate (0.9, 26000)
y = 65.0778 * 772.9605ˣ
y = 65.0778 * 772.9605^(0.9)
y = 25837.76
This is very close and as such is the correct option.

Answer:
The laptop was 934 dollars.
Step-by-step explanation:
The equation you should use to solve this is 120 + 11 (74) since the down payment was a one-time thing and she pays 74 dollars for 11 months, not including the first month.
When you solve that, you will get 934 which is the correct answer.
DB = RT
We know this to be true because both have one “tally” mark indicating that they are congruent (same)
