Given:
The system of equation is
To find:
The solution of given system of equations.
Solution:
The slope intercept form of a line is
Where, m is slope and b is y-intercept.
Write the given equation in slope intercept form.
The first equation is
...(i)
Here, slope is and y-intercept is 4.
The second equation is
...(i)
Here, slope is and y-intercept is -4.
Since the slopes of both lines are same but the y-intercepts are different, therefore the given equations represent parallel lines.
Parallel lines never intersect each other. So, the given system of equation has no solution.
Hence, the correct option is B.
Answer:
$170
Step-by-step explanation:
50/1.25=40 pieces
40 * $4.25 = $170

Draw a diagram of the triangle to understand how the solution works.
Angle C is right angle, so c is the length of side opposite angle C, so it the hypotenuse, and so on.
if B=51, then a is the adjacent side to angle B (excluding hypotenuse).
therefore
a=c*cos(B)=23.5cos(51)=14.8
Note: question is confusing, because a is a length, but instructions require round off to nearest degree, so please check for typos.
