Answer:

On a coordinate plane, 2 lines intersect at (0.5, negative 1)

Step-by-step explanation:

A line on a coordinate plane is an equation. Now, when you have two or more lines on a coordinate plane, then it is a system of equations.

In this case, the solution mean the point where the two lines cross, thus the intersection.

Answer:

s= 15 (nearest integer), 14.8 (to nearest 10ths)

Step-by-step explanation:

here you need to apply the cosine rule,

{s}^{2}  =  {u}^{2}  +  {t}^{2}  - 2ut \cos(s)

substituting the values,

u= 13, t=5 and angle S as 60 and solving will give you the answer 14.76 (2 dp)

The Perimeter Of A Rectanglular Garden Is 84 Feet . The Length Of The Garden Is Twice The Width . What Is The Width Of The Garde
nalin [4]
\bf \stackrel{\textit{perimeter of a rectangle}}{P=2L+2W\implies 2(L+W)}~~
\begin{cases}
L=length\\
W=width\\
--------\\
P=84\\
L=\stackrel{\textit{twice the width}}{2W}
\end{cases}
\\\\\\
84=2(L+W)\implies \cfrac{84}{2}=L+W\implies 42=L+W
\\\\\\
42=(2W)+W\implies 42=3W\implies \cfrac{42}{3}=W\implies 14=W

PLEASE HELP, IT WOULD BE MUCH APPRECIATED!! THANK YOU SO MUCH!! Do the graphs above show a relation, a function, both a relation
rewona [7]

Answer:

Well it definitely can't be a function

Step-by-step explanation:

To find out if a graph is a function, you can use the vertical line test. The vertical line test is when you draw a line down the center and if it hits one point, it's a function. But, when it hits more than one point, it's not. In this case, a line would hit more than one point; meaning that they are not functions.
