Answer:
83.55
Step-by-step explanation:
i think
midpoint= (x, y)
where x=(x1 + x2)/2
y=(y1 + y2)/2
x1=-3, x2=6, y1=5, y2=-11
so x=(-3 + 6)/2= 3/2
y=(5 + -11)/2= (5-11)/2= -6/2= -3
so mid point =(3/2, -3)
hope this helps
Answer:
f(x) = -7x + 1
Step-by-step explanation:
Slope intercept form is
y = mx + b
m is slope
b is y-intercept
--------------------------
y decreases by 7 for each increase of 1 in x
slope = -7
to find "b" plug in one of the points and m = -7
using point (3, -20)
y = mx + b
-20 = -7(3) + b
-20 = -21 + b
b = 1
The equation is
f(x) = -7x + 1
Answer:
Given the equation: 
The general equation of quadratic formula for
where a, b and c are constant;
then, the solution for this equation is given by;
......[1]
From the equation,
we have
a =2, b=14 and c=16
Substitute these values in [1] to solve for x;
or

Simplify:

then,
and

Therefore, the solutions for the given equation is; x =-2 and
