Answer:
3
Step-by-step explanation:
(x+4) ^ 1/3 = 7
We need to cube each side of the equation
(x+4) ^ 1/3 ^3= 7^3
x+4 = 343
Subtract 4 from each side
x+4-4 = 343-4
x = 339
The power raised on each side is 3
For the number line, an open circle will be drawn on the value of 6 and the arrow pointing to the right side.
<h3>Number line and inequality</h3>
Given the inequality expression as shown
-2x + 9 < x − 9
Collect the like terms
-2x - x < -9 - 9
-3x < -18
Divide through by -3
x > -18/-3
x > 6
For the number line, an open circle will be drawn on the value of 6 and the arrow pointing to the right side.

Answer:
Step-by-step explanation:
Total distance /total time=total speed
600÷60=10hrs
300÷75=4hrs
I0-4=6
V=300÷6=50km/h
O= 4 & -4
Explain: it shows on the paper
I'm assuming you're trying to find out how much you'll spend annually on gas: first you would divide the total miles driven in a year (13,000) by your car's mpg (26) giving you a quotient of 500 (the amount of times you'll have to fill up your tank) from here you will need to multiply 500 times the cost of gas ($3.60) giving you a product of $1,800 spent on gas annually.
