1. 1/5
2. 2/5
Answer:F is a unknown number
Step-by-step explanation:Isolate the variable
We are asked to determine the value of a such that the function f(x) = ax^2 + 5 is fit for the point given (-1,2). In this case, we substitute 2 to y and -1 to x. The result is then 2 = a*(-1)^2 + 5 ; 2 = a + 5; a is then equal to -3

<h2>
Answer: (5, 2)</h2>
<h2>
System of equations:</h2>
2x - y = 8
3x + y = 17
<h2>Solve for x:</h2>
2x - y = 8
3x + y = 17
________ +
5x = 25
x = 5
<h2>Plug in x to one of the equations to solve for Y</h2>
2(5) - y = 8
10 - y = 8
-y = -2
y = 2
