ANSWER
Yes, the two expressions are equivalent.
The identity property of multiplication.
EXPLANATION
The identity element for multiplication of real numbers is 1.
This means that, if you multiply any real number by 1, you get the same real number
The given expression is,
These two expressions are equivalent.
The property that is applied is the identity property of multiplication.
A quadratic function's graph being wide or narrow is determined or depended on a-term:
If |a| has a lot of value, for example a = 2 or a = 100. The graph will get narrower if increasing the value of |a|. On the other hand, If |a| has small value, for example a = 1/2 or a = 1/10000. The graph would be wide.
Also it does not matter if a-term is negative or not since a-term being positive or negative determines if a parabola is upward or downward. Only |a| determines how narrow/wide the graph is.
From the question, it is clear that the parabola y = 2x^2 is the narrowest graph since it has the highest |a| value out of all choices.
Answer
Step-by-step explanation:
Let the size of their father's land be x.
The first born received x/4
The second, third and fourth born each received 1/6 * (x - x/4) = 3x/24 = x/8
The portion received by the last born = x - (x/4 + 3*x/8) = x - (x/4 + 3x/8) = x - (5x/8) = 3x/8
3x/8 = 3hectares
3x = 24
x = 8.
. : The initial size of the parcel land was 8 hectares.
Answer:
B. 30
Step-by-step explanation:
A line is 180 degrees, so when we have 100, we subtract that from 180 to get the interior angle of 80.
A triangle has a sum of 180, so we just subtract 80 and 70 from 180 to get 30.

Answer:
1. The y-intercept is 10
2. The slope-intercept is -2
Step-by-step explanation:
1. The y-intercept is 10 because when the x-intercept is 0 the y-intercept should be on the other side.
2. (2,6) and (-1,12)
slope=rise/run= the change of y/the change of x=m=y2-y1/x2-x1
1. change of x=-1-2=-3 and change of y= 12-6=6
2. 6/-3= -2
