1. 3,-10
2. 10x + y
3. 2x - 3y
30/40 say no, so x/1000 would say no. 1000/40=25, 25*30=750. So, about 750 would dislike it.
To find slope intercept form first do rise over run
rise 4 run 3
then find where it crosses the x-intercept to get
y=4/3x-3
Answer to one im pretty sure is 136.4 degrees and to number 2 is a parallelogram (rectangle or square) you know because the side AD is equal to BC and AB is equal to DC
Answer:
78 nickels and 22 dimes
Step-by-step explanation:
Nickels = n, Dimes = d
<u>Number of coins = 100</u>
<u>Total sum in the piggy bank = $6.60 </u>
<u>Consider the first equation in the second:</u>
- 5(100 -d) + 10d = 660
- 500 - 5d + 10d = 660
- 5d = 110
- d = 110/5
- d = 22
- n = 100 - 22
- n = 78
<u>Answer:</u> nickels 78 and dimes 22
