-3x+8=y solve for if the equation is a function or non function
Ket [755]

Answer:

The equation is a function

Step-by-step explanation:

-3x + 8 = y

Reverse the function.

y = -3x + 8

Draw a graph of y vs x  (below)

To determine if the relation is a function,  we can use the vertical line test:  

If a vertical line crosses the graph more than once in any location, the relation is not a function.

We see that at no place will a vertical line intersect the graph more than once.

The relation is a function.

The length of a rectangle is 5 centimeters less than twice its width. The perimeter of the rectangle is 26 cm. What are the dime
iris [78.8K]

Let w and l be the length and height of the rectangle.

We know that:

\begin{cases}l = 2w-5\\2(l+w)=26\end{cases}

Substitute the first equation in the second:

2(l+w)=26 \iff l+w=13 \iff 2w-5+w=13 \iff 3w = 18 \iff w=6

Use the first equation to compute the length:

l=2\times 6 - 5 = 12-5=7

So, length = 7 cm; width = 6 cm
