Step-by-step explanation:

a)-2 is warmer because -2 is a higher number than -5

What would be the maximum value for f(x) = −5x2 + 9
Maru [420]
Well, looking at the expression, it has a -5 on the leading term, that means is not just a quadratic, but is a parabolic graph and because the coefficient of the leading term is negative, is upside-down, or opening downwards.

because it opens downwards, it looks like an arc, comes from the bottom up up up gets to a "maximum" or U-turn (vertex), then goes back down down down.  So, where's the vertex anyway?

\bf \textit{ vertex of a vertical parabola, using coefficients}\\\\&#10;\begin{array}{lccclll}&#10;f(x) = &{{ -5}}x^2&{{ +0}}x&{{ +9}}\\&#10;&\uparrow &\uparrow &\uparrow \\&#10;&a&b&c&#10;\end{array}\qquad &#10;\left(-\cfrac{{{ b}}}{2{{ a}}}\quad ,\quad  {{ c}}-\cfrac{{{ b}}^2}{4{{ a}}}\right)&#10;\\\\\\&#10;\left( -\cfrac{0}{2(-5)}~~,~~9-\cfrac{0}{4(-5)} \right)\implies (0~~,~~9)

so, that's where the vertex is, and the maximum value for f(x), is the y-coordinate of course, or 9.

Answer:11

Step-by-step explanation:Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    3*(x-5)-(18)=0  

Step by step solution :

STEP

1

:

Equation at the end of step 1

 3 • (x - 5) -  18  = 0  

STEP

2

:

STEP

3

:

Pulling out like terms

3.1     Pull out like factors :

  3x - 33  =   3 • (x - 11)  

Equation at the end of step

3

:

 3 • (x - 11)  = 0  

STEP

4

:

Equations which are never true:

4.1      Solve :    3   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

4.2      Solve  :    x-11 = 0  

Add  11  to both sides of the equation :  

                     x = 11

One solution was found :

x = 11
