According to the text, 1 bag of grass seed = 1/6 of the lawn. So if this is right, then it will take 6 bags of grass seeds to cover 1 lawn.
Step-by-step explanation:
given

as equation 1, and

as equation 2.
Now, multiply equation 2 by 2.

now let's this equation be equation 3.
We now use equation 1 + equation 3 to eliminate y and find x.

Now substitute x = 7 into equation 2.

Answer: Yes, In mathematics, an inverse function (or anti-function) is a function that "reverses" another function: if the function f applied to an input x gives a result of y, then applying its inverse function g to y gives the result x, and vice versa, i.e., f(x) = y if and only if g(y) = x.
Answer:
(10,9) P=10
Step-by-step explanation:
find the slope first: y2-y1/x2-x1=(3-1)/1-(-2)=2/3
y=2/3x+b
find b:
3=2/3(1)+b
b=3-2/3
b=7/3
now we find P
(p,9) input the y in the equation
y=2/3 x+7/3
9=2/3x+7/3
9-7/3=2/3x
x=10
