The value of the expression is 4.

We can find this by taking the original equation and plugging in 3 every time we see an x.

$\frac{17 + x}{x + 2}$

$\frac{17 + 3}{3 + 2}$

$\frac{20}{5}$

Answer:

65º

Step-by-step explanation:

The angle of a straight line is 180º, so ∠ABD=180º and ∠ABC=(180-6x)º
The sum of the interior angles of a triangle is 180, so (x+40)º+(3x+10)º+(180-6x)º=180
We can solve from there, x+40+3x+10+180-6x=180
Combine like terms, -2x+230=180
Subtract 230, -2x=-50
Divide by -2, x=25

m∠CAB=(x+40)º=(25+40)º=65º
m∠ABC=(180-6x)º=(180-150)º=30º
m∠BCA=(3x+10)º=(75+10)º=85º

Find the optimal solution for the following problem. (Round your answers to 3 decimal places.)

irina1246 [14]

Answer:

Maximize C = $9x + 7y$

$8x + 10y \leq 17$

$11x + 12y\leq 25$

and x ≥ 0, y ≥ 0

Plot the lines on graph

$8x + 10y \leq 17$

$11x + 12y\leq 25$

$x\geq 0$

$y\geq 0$

So, boundary points of feasible region are (0,1.7) , (2.125,0) and (0,0)

Substitute the points in Maximize C

At (0,1.7)

Maximize C = $9(0) + 7(1.7)$

Maximize C = $11.9$

At (2.125,0)

Maximize C = $9(2.125) + 7(0)$

Maximize C = $19.125$

At (0,0)

Maximize C = $9(0) + 7(0)$

Maximize C = $0$

So, Maximum value is attained at (2.125,0)

So, the optimal value of x is 2.125

The optimal value of y is 0

The maximum value of the objective function is 19.125
