If we are scaling up the surface area by a factor of 10 means that the two dimensions of area are each being increased by 10 times the original size. Therefore, the surface area is increased by a factor of 10 x 10, or by a factor of 100.
Answer: y= -2 - 1/2
Step-by-step explanation:
-4x -2y = 1
+4x +4x
-2y = 4x + 1
/-2 /-2 /-2
y= -2 - 1/2
I think, i may be incorrect but the verbal explanation is; -4x is needed to be moved so you add 4x to both sides and 4x cancels out on the left which leaves -2y on the left (when it was moved "x" is always first). then divide all numbers by -2 to get y by itself. this gives you y= -2 - 1/2 if my calculations are correct.

y = 3/5x + 100
Slope: 3/5
Y-int: 100
Step-by-step explanation:
y = mx + b
<em>replace b with y-int</em>
y = mx + 100
<em>replace m with the slope which is 3/5</em>
y = 3/5x + 100
<em>How do you get slope?</em>
<em>Well I did rise/run with two points so I saw it ran 5 squares and rose only 3.</em>
<em>How do you get the y-int?</em>
<em>Well the y-int is the point where x is 0. So using the point (0,100), since x is 0, the y-int is 100.</em>
Answer:
D. 2x - 2 + 3x
Step-by-step explanation:
First, add 2x and 3x. Then you get 5x. Then you get the equivalent expression 5x-2.
