(a) 1,1 (b) 3,2 (c) 3,2 (d) 1,5
Answer: 2x+3y=18
Step-by-step explanation: Any line parallel to 2x+3y+11=0 is the form 2x+3y =k this can also be written as x/(k/2)+y/k/3 =1 this is the line whose sum of the intercepts is 15, then k/2 +k/3 = 15 after solving we get that indeedk= 18.

Step-by-step explanation:
Answer:
First you have to know what x and y mean in the equation. They told you in the problem that x is the avg # of feet the tree grew each month. That means that the number multiplied by x is the number of months.Y will be the total height. That number is 57.6. When y = 57.6, the number that should be multiplied by x is 16.The tree starts at 8 ft tall, not 0 feet, so the y-intercept in this equation should be 8, because even when 0 months have passed, it will be 8 ft tall. So you know the equation will have the +8 in it added to the slope times x part.It should be d. 16x + 8 = 57.6.

Step-by-step explanation:
Percent means out of 100
20% = 20/100 which can be simplified
20/100 Divide by 10 on top and bottom
=2/10 Divide by 2 on top and bottom
= 1/5
80% = 80/100 which can be simplified
80/100 Divide by 10 on top and bottom
= 8/10 Divide by 2 on top and bottom
=4/5
15% = 15/100 Which can be simplified
15/100 Divide by 5 on top and bottom
= 3/20
