Y2-y1 / x2-x1
-1-4 / 2-(-3)
-5/5
-1
So the answer is A
Answer:
<h3><em>
Real numbers have two categories: rational and irrational. If a square root is not a perfect square, then it is considered an irrational number. These numbers cannot be written as a fraction because the decimal does not end (non-terminating) and does not repeat a pattern (non-repeating).</em></h3>
Step-by-step explanation:
To complete the square, you can add (and subtract) the square of half the x coefficient.
... y = x² -10x + 30
... y = (x² -10x +25) + (30 -25)
... y = (x -5)² +5
Answer:
4 gallons
Step-by-step explanation:
as martizas used up 3/4 gallons, we can calculate the fraction of gas left using: 1−3/4=1/4.
so now we use the fraction we calculated to times with the total volume of gas : 1/4×16=4 gallons
Answer:
4
units
Step-by-step explanation:
The given shape is a right triangle and in right triangles the sum of square length of legs is equal to square length of hypotenuse (represented with x in here):
12^2 + 32^2 = x^2
1168 = x^2 find the root for both sides
4
