64-16x+x^2 i had this same question and that’s the answer i put and for it right :)
Answer:
slope=1
y-int=-8
Step-by-step explanation:
Hey there, we are given quite a lot of information in this problem. First of all, let's make an equation.
y = x - 22
where y = student's age
where x = instructor's age
this equation is correct because x(instructor) - 22 will yield the student's age (y).
If the instructor were 44 years old, the student would be 22 years old.
y = 44 - 22
y = 22
If the instructor were 66 years old, the student would be 44 years old.
y = 66 - 22
y = 44
The overall width of the path and garden is 12 feet.
The area of the entire garden and path is 12 x 12 = 144 square feet.
The path is 1 foot wide, so the garden would be 12 - 2 = 20 feet wide.
The area of the garden only would be 10 x 10 = 100 square feet.
The area of the path only = 144 - 100 = 44 square feet.
1 bag covers 9 square feet:
44 / 9 = 4.88
You would need 5 bags.
Answer:
23 and 4
Step-by-step explanation:
x-y=19
x+y=27
x=19+y
(19+y)+y=27
19+2y=27
2y=8
y=4
x-4=19
x=23
23+4=27
23-4=19
