Determine whether each equation defines y as function of x, 2x+y=8

Answer:

Yes. This equation defines y as function of x.

Step-by-step explanation:

Step 1:

Solve the equation for y (this puts the equations in terms of y)

2x+y=8 becomes

y = 2x - 8

This is a linear equation, which is a funtion.

*Another way to solve this is to look at the graph. Graphing this equation gives us a line. Use the vertical line test to see if it's a function.

To pass the vertical line test (VLT), there can only be one y value to each x value along the graph. If it passes the VLT, the equation is a function.

If it fails the VRT, the equation is not a function.

You will write a 5-paragraph essay explaining how you would solve the following equation:

sattari [20]

Answer:

$x=0$

Step-by-step explanation:

$\frac{7}{3}(2x+3)+\frac{3}{4}(\frac{x}{5}-\frac{15}{2})=\frac{11}{8}$ <-- Given

$\frac{14}{3}x+7+\frac{3}{20}x-\frac{45}{8}=\frac{11}{8}$ <-- Distributive Property

$\frac{280}{60}x+7+\frac{9}{60}x-\frac{45}{8}=\frac{11}{8}$ <-- Find LCD of x-terms

$\frac{289}{60}x+7-\frac{45}{8}=\frac{11}{8}$ <-- Combine Like Terms

$\frac{289}{60}x+7=\frac{56}{8}$ <-- Add 45/8 to both sides

$\frac{289}{60}x+7}=7$ <-- Simplify Right Side

$\frac{289}{60}x=0$ <-- Subtract 7 on both sides

$x=0$ <-- Divide both sides by 289/60

The diagonals of a kite separate the quadrilateral into four congruent triangles

statuscvo [17]

<span>If the sum of two of the sides congruent to each other are greater than that of the sides opposite them, then no. If however the kite forms a rombus ot square, the diagnoles will form four congruent triangles with the base of both being the line of symmetry.
hope this helps :)</span>
