Answer:
Answer (f(x)= (x, plus or minus ___)^2 plus or minus ____ I have worked this to x, 4 a Algebra -> Quadratic Equations and Parabolas -> SOLUTION: Rewrite the quadratic equation in standard form by completing the square.
Step-by-step explanation:
Answer:
Step-by-step explanation:
The initial dimensions of the paper are:
(length)
(width)
After the paper is cut along the diagonal, we remain with a right triangle, of which the length and the width corresponds to the base and the height.
For a triangle, the area is calculated as
where
b is the base
h is the height
Here we have:
Therefore, the area of the triangle is:
Answer:
In standard form: y = 1(-2) + 2
Step-by-step explanation:
y=mx+b
m is the slope (calculate with rise over run, 2/2 is 1)
x is the x intercept (in this case -2)
b is the y intercept (in this case 2)
Answer:
4/5
Step-by-step explanation:
Answer:
A) To solve the ratio, cross multiply then divide.
B)
A / 5/8 = 3/5 / 2/3
Cross multiply:
(5/8 x 3/5) =( A x 2/3)
3/8 = 2/3A
Divide both sides by 2/3:
A = 3/8 /2/3
A = 3/8 x 3/2
A = 9/16
