For 2 1/2, mark a dot right between the 2 and 3, on the fourth tick mark.

For -3/8, go left of 0 3 tick marks. (Right between 0 and -1).

For -1 3/4, go right of -2 by 2 tick marks. (Right between -2 and -1)

Given the linear programming problem, use the method of corners to determine where the minimum occurs and give the minimum value

algol [13]

Answer:

Minimum value of function $C=x+10y$ is 63 occurs at point (3,6).

Step-by-step explanation:

To minimize :

$C=x+10y$

Subject to constraints:

$x\leq 3---(1)\\y\leq 9---(2)\\x+y\geq 9----(3)\\x\geq 0\\y\geq 0$

Eq (1) is in blue in figure attached and region satisfying (1) is on left of blue line

Eq (2) is in green in figure attached and region satisfying (2) is below the green line

Considering $x+y\geq 9$ , corresponding coordinates point to draw line are (0,9) and (9,0).

Eq (3) makes line in orange in figure attached and region satisfying (3) is above the orange line

Feasible region is in triangle ABC with common points A(0,9), B(3,9) and C(3,6)

Now calculate the value of function to be minimized at each of these points.

$C=x+10y$

at A(0,9)

$C=0+10(9)\\C=90$

at B(3,9)

$C=3+10(9)\\C=93$

at C(3,6)

$C=3+10(6)\\C=63$

Minimum value of function $C=x+10y$ is 63 occurs at point C (3,6).

If the function f(x) = (2x - 3)2 is transformed to g(x) = (-2x - 3), which type of transformation occurred?

san4es73 [151]

Answer:

A. horizontal reflection

Step-by-step explanation:

Given:

$f(x)=(2x-3)^2$

$g(x)=(-2x-3)^2$

To identify the type of transformation.

Solution:

On close observation of the functions we find the that sign of $x$ has changed in $g(x)$ with other terms being constant.

<em>Thus, the transformation statement can be given as:</em>

$f(x)\rightarrow f(-x)$

As:

$f(x)=(2x-3)^2$

$f(-x)=(2(-x)-3)^2= (-2x-3)^2 = g(x)$

The transformation $f(x)\rightarrow f(-x)$ describes horizontal reflection of function across the y-axis.

Thus, $f(x)$ is horizontally reflected across y-axis to get $g(x)$ .
