-5,4 would be in the quadrant 1<span />
Answer:
A. x=2, y = 7.
B. (2, 7).
Step-by-step explanation:
A. You can eliminate y by subtracting the equations:
y = 8x - 9
y = 4x - 1 Subtract:
0 = 4x - 8
4x = 8
x = 8/4 = 2.
Now substitute for x in the first equation:
y = 8(2) - 9 = 7.
Check in the second equation:
y = 4x - 1
7 = 4(2) - 1 = 7. Check is OK.
B. On the graph they will intersect at the point (2, 7).
They will intersect here because the values x=2 and y=7 satisfy both the 2 equations.
Hey!~
Log 5 + Log 2 = 1
Hope this helps and have a nice day!

Answer:
The answer to your question is: L = 30 ft
Step-by-step explanation:
Data
man = 6 ft
man shadow = 5 ft
lamppost shadow = 25 ft
lamppost height = ? = L
Process
![\frac{6}{5} = \frac{L}{25}](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B5%7D%20%3D%20%5Cfrac%7BL%7D%7B25%7D)
![L = \frac{6 x 25}{5}](https://tex.z-dn.net/?f=L%20%3D%20%5Cfrac%7B6%20x%2025%7D%7B5%7D)
![L = \frac{150}{5}](https://tex.z-dn.net/?f=L%20%3D%20%5Cfrac%7B150%7D%7B5%7D)
L = 30 ft
Answer:
$108
Step-by-step explanation:
1 box = $12
18 boxes = 12×18 = $216
Total = 18×65 = 1170 pens
Cost price, Cp = $216
3 = $1
378 = 378/3 = $126
1170-378= 792 pens remaining
4 = $1
792 = 792/4 = $198
Total selling price, sp = 126+198 = $324
Profit = Sp - Cp = 324 - 216 = $108
