Answer:
$57
Step-by-step explanation:
Given that:
Earnings per hour for washing cars = $9
Earnings per hour for walking dogs = $6
Number of hours for which car washing is done =
Number of hours taken for walking dogs =
Earnings for hours for washing cars = Per hour earnings multiplied by number of hours = $9
Earnings for hours for walking dogs = Per hour earnings multiplied by number of hours = $6
Total earnings by both = $()
Now, given that
Number of hours spent washing cars = 5 hours
Number of hours spent walking dogs = 2 hours
Therefore, total earnings by both = 9 5 + 6 2 = <em>$57</em>
F(x) = 6x² + 5 - 42x
first step in writing the f(x) in vertex form? WRITE THE FUNCTION IN STANDARD FORM.
f(x) = 6x² - 42x + 5
Exponents must be in decreasing order.
Micah did not explain the last step correctly. You cannot cross out a term from the numerator and denominator unless it is a factor. In other words, x² needed to be multiplied and not added in order to cross it out.
-2 + 4x - 4
= 4x-6
Make sure to distribute everything and then combine like terms.
Answer: 4x-6
