Answer:
The answer is 2.89 in 2dp
3 cube is 27
27 minus 6.8 is 20. 2
20. 2 decide by 7 is 2.89
the answer would be 3
Step-by-step explanation:
Because 3 to the third power is 27 and 6 times 8 is 48 so you subtract 27 and 48 and you get 21 so you divided 21 and 7 and you get 3. sorry if that's confusing but I hope it helped.
1/2
1/2.(x+12)=4x-1
x+12=2(4x-1)
x+12=8x-2
Group like terms
12+2=8x-x
14=7x
Divide both sides by 7
x=2
The answer is D. The roots are just where the line crosses the y axis.
x=4.5
