First, find the slope of the line. Use the two points given, (-4,0) and (4,2), in the slope formula rise over run. The change in rise is 2 and the change in run is 8, meaning that the slope is 2/8, simplified to 1/4. The y-intercept is 1, shown by the graph and the dashed line and shaded area means that the inequality symbol must be <. Slope-intercept form is shown as y = mx + b, so after putting our information in to the equation the answer is y < 1/4x + 1. Hope this helps!
<span>Answered by the following sums -
Outer square area = 4x^2
side of the square = 2x which is equal to diameter of circle == diameter of inner square.
radius of circle = x
diameter of outer square = 2*sqrt(2)*x
consider side of inner square = a
so a^2 + a^2 = (2x)^2
2a^2 = 4x^2
a = x*sqrt(2)
So area of inner square will be = 2x^2</span>
Answer:
289 messages
equation: 
graph: attached below
Step-by-step explanation:
We can write this in slope-intercept form, or
. Since x is defined as the #of text messages, and 0.05 is the cost of a text message, 0.05 will be m. 45.5 is the base price, or the y-intercept, so it will be b.
Plugging in these numbers, we get 
now we make y = 60, since that is the total amount they have

So, they can send 290 messages for 60, but they need the bill under 60, so 1 text message less will be 289, and that's enough.
Answer:
The length of one side of the square is 11.8 inches.
Step-by-step explanation:
Since a square has 4 sides and they are all equal, you want to divide 47 by 4.
You will get 11.75 inches per side.
However, since they want you to round to the near tenth, the answer will actually be 11.8 inches.
