To find the X intercept, replace y with 0 and solve for x:
9x + 21(0) = 16
9x = 16
x = 16/9
To find the Y intercept, replace x with 0 and solve for y:
9(0) + 21y = 16
21y = 16
y = 16/21
X-intercept is 16/9
y intercept is 16/21
The plane roughly goes 458 miles an hour, at this rate the plane will travel 3664 miles in 8 hours
You first multiply the outside exponents into the numbers in the parentheses.
When you have an exponent being multiplied directly to another exponent, you multiply the exponents together.
For example(because I am a bad explainer):
When you divide an exponent by an exponent, you subtract the exponents
For example:
When you have a negative exponent, you move it to the other side of the fraction to make the exponent positive
For example:
You can think of it like this if you want:
Now multiply the outside exponents into the exponents in the parentheses
Divide 27 and 9
Your answer is
Since 1 liter is equal to 1000 milliliters, to convert from milliliters, you move the decimals 3 times to the left. So 48.5 mL becomes 0.0485 liters.
You can also divide the mL amount by 1000 to get the answer 0.0485
