Find the minimum value of the function f(x) = x2 + 5x – 6
Klio2033 [76]

So the easiest method to find the vertex (the minimum in this case) to do this is to find the axis of symmetry, then plug it into the function.

Firstly, the equation to find the axis of symmetry is x=\frac{-b}{2a} , with b = x coefficient and a = x^2 coefficient. The equation equation can be solved as such:

x=\frac{-5}{2*1}\\\\x=\frac{-5}{2}\\\\x=-2.5

Since the vertex falls on the axis of symmetry, we know that the x-coordinate of the vertex is -2.5. Now to solve for the y-coordinate, plug in x with -2.5 and solve as such:

f(-2.5)=(-2.5)^2+5*(-2.5)-6\\ f(-2.5)=6.25+(-12.5)-6\\ f(-2.5)=-12.25

Now putting it all together, our minimum value (vertex) is (-2.5,-12.25).

the sum of four times a number and 6 times a second number is 36. The difference between five times the second number and three
Irina-Kira [14]
This is a simple system of equations. We first write the words in math as 4x + 6y = 36 and 5y - 3x = 49.

Now we isolate 5 in the second equation to get 5y = 49+3x or y=(49+3x)/5. We can now substitute our value for y into our first equation and simplify.

4x + 6y = 36 is the same as 4x+6((49+3x)/5) = 36.  This can be simplified to 4x+(294+18x)/5 = 36, which is the same as 20x+294+18x = 180.  We can combine like terms to get 38x +294 = 180 or 38x = -114. Now we divide by 38 on both sides to get x = -3.

Now that we have our value for x, we substitute that value into the second equation and solve for y.

5y - 3x = 49 is the same as 5y - 3(-3) = 49 or 5y+9 = 49.  This can be simplified to 5y=40 or y=8.

Our values for x and y are -3 and 8.  Hope this helps!

Which of the following systems of equations has no solution?
Law Incorporation [45]
For option d:
5x - 7y = 10 . . . . . (1)
10x - 14y = 8 . . . . (2)

(1) x 2 => 10x - 14y = 20 . . . . . (3)

(2) - (3) => 0 = -14              [not possible]

Therefore, the set of equations in option d, has no solutions.
