Answer:
v= 13
w= -32
Step-by-step explanation:
2v+6w=-36
5v+2w=1
2w= 1-5v
2v+ (3)(1-5v)= -36
2v+3-15v= -36
3-13v =-36
3--36= 13v
39= 13v
13 = V
5×13+2w=1
65+2w=1
1-65= 2w
-64=2w
-32=w

To find a solution for the linear equation, the first step is to write the equation in slope-intercept form:
-Pass the x-term to the right side of the equation by applying the opposite operation to both sides of the equal sign:
-Divide both sides by -2:
Once you have expressed the equation of the line in slope-intercept form, replace it with any value for x and calculate the corresponding value of y, for example, x=2
One solution for the linear equation is x=2 and y=-6, you can check the solution by replacing the values on the original equation, with both values the result should be 8:
As you can see the values are a valid solution for the linear equation.
So the solution is:
Based on the dimensions of the wall and the triangular glass, the number of mirrors needed is 215 mirrors.
<h3>What number of mirrors are needed?</h3>
First find the area of the wall:
= 36 x 93
= 3,348 m²
The area of the triangle, assuming it is an equilateral triangle is:
= (√3/4) x 6²
= 15.59 m²
The number of mirrors needed is:
= 3,348 / 15.59
= 215 mirrors

Since this is a piecewise function, we will want to find the right equation to use. We want to find f(2) so we will find the equation to use when x=2. This will be the third equation because it is -2<=x<=2. We then plug 2 into x^2 -2. This will give us (2^2)-2 = 4-2 = 2.
Answer:
585/3 = 195 students
Step-by-step explanation:Each group of three created (or used) 9 pictures, so that means three pictures per student.
Dividing 585 students by 3 pictures per student means that there are 585/3=195 students.
