Answer:
B
Step-by-step explanation:
There are no repeating values for x, for different values plugged in for y.
Answer:
4
Step-by-step explanation:
Calculate the distance using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = B(0, 0) and (x₂, y₂ ) = (, )
AB = +
= +
=
=
= 4
Answer:
Part a) The quadratic function is
Part b) The value of x is
Part c) The photo and frame together are wide
Step-by-step explanation:
Part a) Write a quadratic function to find the distance from the edge of the photo to the edge of the frame
Let
x----> the distance from the edge of the photo to the edge of the frame
we know that
Part b) What is the value of x?
Solve the quadratic equation
The formula to solve a quadratic equation of the form
is equal to
in this problem
we have
so
substitute in the formula
-----> the solution
Part c) How wide are the photo and frame together?
5/8=10×w this is my equation then i divide by 10 on both sides
w=6.25
