Answer:
-1/2
Step-by-step explanation:
Formula to find slope is y2-y1/x2-x1
Chose one ordered pair to be the 2 and the other one to be the 1
I chose the 2nd one to be 2.
Plug in the y-value from the 2nd ordered pair to y2 because its the 2.
Plug in the x-value from the 2nd ordered pair to x2 because its the 2.
Now you have 0-y1/5-x1
Do the same thing but for the 1.
Plug in the y-value from the 1st ordered pair to y1 because its the 1.
Plug in the x-value from the 1st ordered pair to x1 because its the 1.
Now you have 0-5/5--5
In this situation, you have 2 minus signs.
2 minus = 1 positive.
Now you have 0-5/5+5
Simplify.
Now you have -5/10.
Simplify.
-1/2.
Hope this helps!
Answer:
Step-by-step explanation:
25x2 − 40x + 16 = (5x)² - 2*5*4 + 4² { (a - b)² = a² - 2ab + b² }
= (5x - 4)² { here a = 50 and b = 4}
Side of the square = 5x - 4 units
Part B:
25x2 − 16y2 = (5x)² - (4y)² { a² - b² = (a + b) * (a - b) }
= (5x + 4y) * (5x - 4y) { here a = 5x and b = 4y}
Dimensions of Rectangle: (5x + 4y) ; (5x - 4y)
