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:
4/5x + y = -2
Step-by-step explanation:
Answer:
37.5% that is the answer
Step-by-step explanation:
make two triangles. make the bottom of one triangle 135 as the shadow and "x" as the height. the other traingle should have 9 at the bottom and 5.3 as the height. then make a proportion
Perpendicular to the base.
Hope this helps!!!
