Part A:
From the graph, it seems that the lines intersect at (3,-1)... This seems to be the solution...
Part B:
g(x) is a negative line, and the slope is 2 (from rise/run). Y int. = 5. So, the equation is -2x+5. Plug in some numbers for this; say 1 and 2. The coordinates would be (1,3) and (2,1).
Part C:
The 2 graphs seem to intersect at (0,5), so this is the solution...
ALL of this is based on only looking at the graph, which is no better than drawing lines on the sand.. For example, the y intercept for g(x) could be 4.9 or 5.1, and I don't know the equation for f(x)... Based on the info I have, gave my best answers..
Hope this helps..
Answer:
The sales tax on the computer is <span>$45.10</span>.
Explanation:
The sales tax (x) on the computer can be expressed by the equation:
<span>x=550×<span>8.2100</span></span>
<span>x=5.5×8.2</span>
<span>x=<span>45.1</span></span>

we know that
A geometric sequence, is a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio.
where
a_n----> 
term of the sequence
r ---> is the common ratio
a ---> the first term of the sequence

Answer:
15
Step-by-step explanation:
It does not divide evenly, but there are 15 groups of 6 in 95.
Answer:
1. 450
2. 8(12)+3(2.50)
3. 10
4. 32
Step-by-step explanation:
1. 700-250=450
2. 8 people going to the theater. If tickets cost $12 each, you multiply 8 by 12 to get the ticket cost. If 3 people ordered drinks and drinks cost $2.50, you multiply 3 by 2.50 to get the drink cost. Since this is asking for the total cost you add your first 2 answers to get the final cost.
3. 12/3=4, which means one pound costs $4. To find the amount bought with $40, divide 40 by 4, which equals 10 pounds.
4. To find percents, you turn your percentage into a decimal by dividing by 100. (400/100=4), then you multiply that by the number you are trying to find a percentage of(8x4=32). This gives you the answer 32.
