Answer:
Step-by-step explanation:
Δ = 
VΔ = 4 * 8 = 32
a = (- 4 ± 32) * 
a' = 7/2
a''= 9/2
Answer:
the second one
Step-by-step explanation:
y = 2/3 (x +6)-5
Answer:
<em>s= </em>-5.57 (rounded to the nearest hundredth)
Step-by-step explanation:
1. Multiply s and 2 by 7.
You'll get -7s-14. We'll come back to this later
2. Subtract 12 from 37.
You'll get 25
3. Add 14 to both sides so that you cancel out the -14.
The equation stands as -7s= 39
4. Divide both sides by -7 so that we leave <em>s </em>by itself.
s= -5.57142857
Answer:
288
Step-by-step explanation:
Find the 18 on the x axis. Go up to the line. Then go left and you will be at 288 on the y axis.
You can also divide a known coordinate to find the rate of change, since the graph is proportional. Use (6, 96). y/x = rate of change
96/6 = 16.
Now multiply 18 and 16 to get the number of cookies.
18 x 16 = 288
