You would add the area of the square with the area of the triangle.

Square: length x width 
In your case, it would be 100in²

Triangle: length x height x 1/2 (or length x width divided by 2)
16-10 would be 6 (height) 10-6= 4 (length)
6 x 4 x .5 = 12in²

100in²+12in²=112in²

The area is 112in²

Graph the linear equation. Find three points that solve the equation, then plot on the graph. -3x+2y=2
aleksandrvk [35]

First you need to put the equation into slope form which is y = mx + b

-3x + 2y = 2

2y = 3x + 2

y = 1.5x + 1

In this equation the y-intercept is 1 and the slope is 1.5 or 3/2.

To graph the line you can start at the y-intercept then move up 3 and to the right 2 or down 3 and to the left 2.

Three points are (2, 4) , (-2 ,-2), (4, 7).

Hope this helps! Mark as Brainliest please! :)))

NISA [10]

Answer:

the number of callers on average are in the system at any given time is 440

Step-by-step explanation:

Given that

The calls that arrive in a call center have an average rate of 100 per min

But it we involve the waiting time so the call needed 4.4 minutes

We need to to find no of callers are in the system at any given time

SO,

= 100 per min × 4.4

= 440

hence, the number of callers on average are in the system at any given time is 440

The same would be considered
