Step-by-step explanation:
The given expression is,







<span>x intercept when f(x) = 0
so
</span><span>x^2-81 = 0
x^2 = 81
x = + 9 and x = -9

Volume of space inside shop is 288 m³
<u>Given that;</u>
Dimensions of rectangle = 8 meter , 12 meter , 3 meter
<u>Find:</u>
Volume of space inside shop
<u>Computation:</u>
Volume of rectangle = [l][b][h]
Volume of rectangle = Volume of space inside shop
So,
Volume of space inside shop = [8][12][3]
Volume of space inside shop = [96][3]
Volume of space inside shop = 288 m³

Answer:
2x-3y=9 and 4x-6y=30
Step-by-step explanation:
hello :
note y=(2/3)x+5 no y=23x+5
2/3 is the slope....... all lines parallel to this line has same slope.
1) 2x-3y=9 means : 3y = 2x-9 divide by 3 : y=(2/3)x-3..same slope.
2) 4x-6y=30 means : 6y= 4x-30 divide by 6 : y=(4/6)x -30/6
but 4/6 = 2/3 so : y=(2/3)x-5..same slope.
