Explain what is happening at this step in the solving equation process.

aleksklad [387]

Answer:

1. After solving we get value of x: $\mathbf{x=\frac{6}{11} }$

2. After solving we get value of x: $\mathbf{x=\frac{6}{11} }$

Step-by-step explanation:

We need to Solve the equations.

1. $10 - 6 x = 4 + 5 x$

Step 1: Subtract 5x on both sides

$10 - 6 x-5x = 4 + 5 x-5x\\10-11x=4$

Step 2: Subtract 10 on both sides

$10-11x-10=4-10\\-11x=-6$

Step 3: Divide both sides by -11

$\frac{-11x}{-11}=\frac{-6}{-11}\\x=\frac{6}{11}$

So, after solving we get value of x: $\mathbf{x=\frac{6}{11} }$

2. $7-6x=1+5x$

Step 1: Subtract 5x on both sides

$7 - 6 x-5x = 1 + 5 x-5x\\7-11x=1$

Step 2: Subtract 7 on both sides

$7-11x-7=1-7\\-11x=-6$

Step 3: Divide both sides by -11

$\frac{-11x}{-11}=\frac{-6}{-11}\\x=\frac{6}{11}$

So, after solving we get value of x: $\mathbf{x=\frac{6}{11} }$

Find the maximum/minimum value of the function y = x2 - (5/3)x + 31/36.

AysviL [449]

Answer:

Step-by-step explanation:

Given a parabola in standard form, y = ax² + bx + c ( a ≠ 0 ), then

minimum/ maximum value is the y- coordinate of the vertex.

The x- coordinate of the vertex is

$x_{vertex}$ = - $\frac{b}{2a}$

y = x² - $\frac{5}{3}$ x + $\frac{31}{36}$ ← is in standard form

with a = 1 and b = - $\frac{5}{3}$ , thus

$\frac{x}{vertex}$ = - $\frac{-\frac{5}{3} }{2}$ = $\frac{5}{6}$

Substitute this value into y

y = ( $\frac{5}{6}$ )² - $\frac{5}{3}$ ( $\frac{5}{6}$ ) + $\frac{31}{36}$

= $\frac{25}{36}$ - $\frac{25}{18}$ + $\frac{31}{36}$ = $\frac{1}{6}$

Since a > 1 then the vertex is a minimum, thus

minimum value = $\frac{1}{6}$ → A
