Answer:
y=
+3
Step-by-step explanation:
1. Replace f(x) to x and replace x with y.
x=5y-15
2. Then, add 15 to both sides
x+15=5y-15+15
5y=x+15
3. Divide both sides by 5
=
+
y=
+3
4. Enjoy your answer.
Answer:
First number --> x
Second number --> y
x + y = 14 --> x = 14 - y
x - y = 4
so
14 - y - y = 4
14 - 2y = 4
2y = 10
y = 5
so
x = 14 -5
x = 9

Answer:
160cm^2
Step-by-step explanation:
So the surface area is basicly the sum of all the areas of the rectangles in this prism.
So the formula can be written as
.
The w stands for width, the h stands for height, and the l stands for length.
5cm is the width, 10 cm is the length, and 2 cm is the height.
So inserting all those values for the variabls the formula now looks like this.
.
So 5*10 is <u><em>50</em></u>
2*10 is <u><em>20</em></u>
2*5 is <em><u>10</u></em>
So adding all that up we get 80.
Then multiplyong that by 2 we get 160cm^2.
