Answer:
A
Step-by-step explanation:
Both lines have a y-intercept of 3.
Both lines are solid and colored below, which means both inequalities have the symbol .
One line has a positive slope, and one line has a negative slope.
The only answer that conforms to the above is a)
Answer: A
<span>let the two number be x and y
x + y = 156
y = 156 - x
Product of the 2 numbers:
x(156 - x) = </span>
<span>
This maximum value occurs when x = -b / (2a). [This is a standard rule]
</span>
a = -1 and b = 156
x =
x = 78
y = 156 - 78 = 78
product = 78 x 78 = <span>6084 </span>
So the two positive numbers are 78 and 78.
