Answer:
AC = 
Step-by-step explanation:
Assuming you require AC
Using Pythagoras' identity in the right triangle
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides , that is
AC² + BC²= AB²
AC² + 7² = 8²
AC² + 49 = 64 ( subtract 49 from both sides )
AC² = 15 ( take square root of both sides )
AC =
≈ 3.87 ( to 2 dec. places )

The answer is -1/4 I’m in 11th grade trust me
Answer:
y = 1.5x + 3.2009
Step-by-step explanation:
I plotted your points and drew a linear regression line.
Its equation is
y = 1.5x + 3.2009
The regression line ignores the fact that the points fall along a smooth curve.
A parabolic regression line fits the data much better.
The equation for that line is
y = - 0.1647x² + 4.1357x - 5.6946
It is the equation for a vertical parabola opening downward.
