Answer:
Slope = 2/3 and y-intercept = 490
Step-by-step explanation:
2x + 3y = 1470
3y = -2x + 1470
y = 2/3 x + 490 <----------Slope intercept form
Slope = 2/3 and y-intercept = 490
so, that gives you the compounded amount, after 10 years, if you want to know how much interest was earned? well, just subtract the Principal from the Amount, or A - P <--- that's how much interest was earned
7X-4=6X-4-X
7X-6X+X=0
2X=0
X=0
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>
