Step-by-step explanation:
Answer:
8/5 or 1 3/5 ft
Step-by-step explanation:
The area of a rectangle is given by
A = l*w
The area is 4/5 and the width is 1/2
4/5 = 1/2 *l
Multiply each side by 2
2*4/5 = 2*1/2 *l
8/5 = l
Changing to a mixed number
l = 1 3/5
Answer: x=6 and y = -4 and x= -1 and y=3
Step-by-step explanation:
Your two equations are y = -x + 2
and y=x^2 -6x + 8
Subsituting y=-x+2, we get
-x + 2 = x^2 -6x + 8
x^2 -5x +6 = 0
Solving by the quadratic formula gives,
(5+/- sqrt(25+24))/2
Thus, the two solutions are 6, and -1.
So x=6
y= -4 and
x=-1
y= 3
