X + y = 54
x - y = 10
Add them to get: 2x = 64
x = 32
and plugging in x = 32 to either eqn: y = 22
Ans: the numbers are 22 and 32
The answer is D, 4.2. not what the person said

Answer:
See graph in attachment
Step-by-step explanation:
We want to graph the function,
First, let us rewrite the function in the vertex form;
The parabola opens downwards because
The vertex of the parabola is .
At y-intercept, .
This implies that,
At x-intercept,
This implies that;
This equation has no real number solutions because of on the right hand side. This implies that the graph has no x-intercepts.
We therefore draw a maximum graph through the vertex and the y-intercept to obtain the graph in the attachment.
