9ft squared I believe that you'd have to times 5x6 which is 30 and she used 30% of yellow fabric so 30% of 30 is 9.
Part 1We are given
. This can be rewritten as
.
Therefore, a=1, b=-18, c=0.
Using the quadratic formula
The values of x are
Part 2Since the values of y change drastically for every equal interval of x, the function cannot be linear. Therefore, the kind of function that best suits the given pairs is a
quadratic function. Part 3.The first equation is
.
The second equation is
.
We have
Factoring, we have
Equating both factors to zero.
When the value of x is 6, the value of y is
When the value of x is -3, the value of y is
Therefore, the solutions are (6,38) or (-3,11)
Answer: 90
Step-by-step explanation:
Answer:
-3/2x+3
Step-by-step explanation:
y=mx+c
y=-3/2x+c
Substitute x and y values,
c=3
Therefore,
equation of line p=-3/2x+3
Answer:
The number of balloons varies directly with the number of tables. The two variables are directly proportional. The relationship of balloons to tables is the ratio 5:1, where 5 is the constant of variation. Use the equation y = kx, where k is the constant of variation resulting in the equation y = 5x.
