Answer:
X = 2
Y = 1
Step-by-step explanation:
x + 4y = 6
3x + 3y = 9
3x + 12y = 18
3x + 3y = 9
9y = 9
x + 4y = 6
y = 1
x + 4 * 1 = 6
y = 1
x + 4 = 6
y = 1
x = 2
so there ia only 1 solution for this equation is (2;1)
Done :))
Based on the characteristics of <em>linear</em> and <em>piecewise</em> functions, the <em>piecewise</em> function
is shown in the graph attached herein. (Correct choice: A)
<h3>How to determine a piecewise function</h3>
In this question we have a graph formed by two different <em>linear</em> functions. <em>Linear</em> functions are polynomials with grade 1 and which are described by the following formula:
y = m · x + b (1)
Where:
- x - Independent variable.
- y - Dependent variable.
- m - Slope
- b - Intercept
By direct observation and by applying (1) we have the following <em>piecewise</em> function:

No, The answer should be 240
Step-by-step explanation:
- The first step to finding the Surface Area was done well and was right but you got confused when trying to add the area of each shape
- There is 3 Rectangles and 2 Traingles.
- Let's start with the area of the triangles. 1/2bh is the formula for finding area of Traingles. 1/2(4)(6) = 12. We have two Traingles so that would be 24.
- Now we have three rectangles with different lengths we need to calculate.
- Rectangle 1 = 12 * 8 = 96
- Rectangle 2 = 12 * 6 = 72
- Rectangle 3 = 12* 4 = 48
- 24+96+72+48 = 240.
- So, the surface area of the rectangular prisim is 240
We solve this the following way:
tie dyed shirts = x
white shirts = y
x = 3y
x + y = 196
3y + y = 196 (we substitute the x with the 3y in the main equation)
4y = 196 (divide this)
y =49
x = 147
The man sold 147 tie dyed shirts and 49 white shirts.
