Answer:
8+7
Step-by-step explanation:
8+7 adds up to 15
The other three add up to 14
Answer:
0 < k < 2
Step-by-step explanation:
<u>In the first quadrant both of x and y get positive values, so </u>
<u>And replacing x with 2k in the second equation:</u>
- 3x + 2y = 12
- 3*2k + 2y = 12
- 2y= 12 - 6k
- y = 6 - 3k
<u>Since y > 0:</u>
<u>Combining both k > 0 and k < 2, we get:</u>
Y= mx +b slope intercept form.
b= 60, now do rise over run to find m
4/4= 1, m=1
Final equation: y=1x+60
When you add any fractions, you need to find a common denominator. In this case they have no common factors so you just multiply them together. First multiply the first fraction by
which gets you
. Then multiply the second fraction by
to get
. Now you can add them together to get
.
(b)
now you can pull out root 2 and get
which equals
9 and then 4 for every 9 goldfish, there are 4 gallons of water
