First we divide 408 with 16 giving us 25.5 then we multiply 11 with 25.5 which then gives us 280.5. The answer is 280.5 miles.

Graph the solution to the system -x+y>2 X+2y>2

mariarad [96]

Answer:

$\begin{bmatrix}y>2+x\\ y>\frac{2-x}{2}\end{bmatrix}$

Step-by-step explanation:

Step 1: Solve the system of equations

$\begin{bmatrix}-x+y>2\\ x+2y>2\end{bmatrix}$

Isolate $y$ for $-x+y>2$

$\mathrm{Add\:}x\mathrm{\:to\:both\:sides}$

$-x+y+x>2+x$

$y>2+x$

Isolate $y$ for $x+2y>2$

$\mathrm{Subtract\:}x\mathrm{\:from\:both\:sides}$

$2y>2-x$

$\mathrm{Divide\:both\:sides\:by\:}2$

$\frac{2y}{2}>\frac{2}{2}-\frac{x}{2}$

$y>\frac{2-x}{2}$

$\bold{=\begin{bmatrix}y>2+x\\ y>\frac{2-x}{2}\end{bmatrix}}$

Step 2: Graph

Instructions for graphing:

$\mathrm{1.\:Graph\:each\:inequality\:separately.}$

$\mathrm{2.\:Choose\:a\:test\:point\:to\:determine\:which\:side\:of\:the\:line\:needs\:to\:be\:shaded.}$

$3. \mathrm{The\:solution\:to\:the\:system\:will\:be\:the\:area\:where\:the\:shadings\:}\\\mathrm{from\:each\:inequality\:overlap\:one\:another.}$

When done, it should look like this:

Answer:

16.2

Step-by-step explanation:

Tan(angle)=opposite/ adjacent

Angle= 45

Opposite side= x

Adjacent side =10

Substitute into equation: tan(45) = x/ 10

Rearrange (multiply each side by 10): 10 x tan(45) = x

Then work it out on calculator
