There's some unknown (but derivable) system of equations being modeled by the two lines in the given graph. (But we don't care what equations make up these lines.)

There's no solution to this particular system because the two lines are parallel.

How do we know they're parallel? Parallel lines have the same slope, and we can easily calculate the slope of these lines.

The line on the left passes through the points (-1, 0) and (0, -2), so it has slope

(-2 - 0)/(0 - (-1)) = -2/1 = -2

The line on the right passes through (0, 2) and (1, 0), so its slope is

(0 - 2)/(1 - 0) = -2/1 = -2

The slopes are equal, so the lines are parallel.

Why does this mean there is no solution? Graphically, a solution to the system is represented by an intersection of the lines. Parallel lines never intersect, so there is no solution.

Find the area of the triangle.<br> 3 cm<br> 11 cm<br> C с<br> 14.5 cm
boyakko [2]

Answer: The answer is 43.5 because when using the formula you get this result.

Step-by-step explanation: Area of triangle is base x height divided by 2. So do our base 14.5 and our height 6 and multiply them together. 14.5 x 6 = 87 / 2 = 43.5

How do I find surface area of a prism?
nlexa [21]

Answer:

Step-by-step explanation:

If you want the surface area of a rectangular prism, then you'll use a formula resembling this:

A = 2(area of end) + 2(area of top) + 2 (area of side).

Example:  suppose the dimensions of the prism are 3 in by 5 in by 8 in.

Then the total surface area is:

A = 2(3*5) + 2(3*8) + 2(5*8) square inches, or 2(15) + 2(48) + 2(40) sq in, or

A = 30 + 96 + 80 sq in, or A = 206 sq in

Help me plz im stuck
viva [34]

Answer:

A) Fill the blanks, Fail, 0.15, Success, 244, 0.61

B) 240 times

Step by-step explanation:

A) Void , 96, 0.24

    Fail, 60, it should be 0.15 because 60/400

     Success, 400 - 96- 60 or 244 and the relative frequency is 0.61.

B)    

There is a total of 1000. If the relative frequency is 0.24, multiply 0.24 by 1000 to get the amount of times YOU would expect to be VOID.

Or in other words , 240 times

By proving it add all up

0.24 x 1000 + 0.76 x 1000 = 1000
