Hello!
A line is one dimensional. This means it has one dimension, it's length. Therefore, you could measure the length of a line.
I hope this helps!
Our system of equations is:
y = -3x + 9
y = -x - 5
To solve this system of equations, we are going to use substitution. This means that we are going to substitute the second equation into the first equation since both are already solved for y in terms of x.
y = -3x + 9
-x - 5 = -3x + 9
Now, we must simplify by moving all of the constant terms to one side of the equation and all of the variable terms to the other side.
-x - 5 = -3x + 9
2x - 5 = 9
2x = 14
Finally, to undo the multiplication between the coefficient 2 and the variable x, we must divide both sides by 2 to get the variable x alone.
x = 7
Next, we must substitute in this value we have solved for x into one of the original equations to solve for the other variable, y.
y = -3x + 9
y = -3(7) + 9
To simplify, we must multiply through the parentheses and combine like terms by addition.
y = -21 + 9
y = -12
Therefore, your final answer is x = 7 and y = -12, or as an ordered pair (7, -12).
Hope this helps!
Answer:
The surface area of the triangular prism is 
Step-by-step explanation:
Step 1: Finding the two area of two triangles
Area of the triangle = 
Area of the triangle = 
Area of the triangle = 26.117
Area of 2 triangles = 
Step 2: Finding the area of the side rectangles
Area of the rectangle = 
Area of the rectangle 1 = 
= 23.56
Area of the rectangle 2 = 
= 32.3
Area of the rectangle 3 = 
= 37.24
Step 3: surface area of the triangular prism.
Surface area of the triangular prism = 52.234 + 23.56 + 32.3 + 37.24
Surface area of the triangular prism = 145.334
