The tenth is the first number after the decimal which is 6. To see if it rounds up or stays the same, check the number before it which is 6 as well. 5 + a number you round up so 7.668 -> 7.7
On the TI-84 graphing calculator you press the 2nd button in the top left corner and then the x^2 button that has a blue radical sign above the button.
Step-by-step explanation:
<h2>y = √—16x²+8x—2√8x+1+2</h2>
Answer:
If charge per day =x
and charge per mile =y
6x + 550y = 337
3x + 350y = 185
multiple the second equation by 2
6x+700y=370
subtract the first equation from this equation
150y=33
y=0.22
Now we plug the y back in to one of the initial equations to get the value of x
3x+350(0.22)=185
x=36
Charge per day is $36 and charge per mile is $0.22
