It does matter because for the understanding of to make it easier.
y=mx+b
because the y=2x-1, so m=2
because we know (4.2), so we can bring it in to the function:
2=2x4+b
2=8+b
b=-6
So the other one is: y=2x-6
in other way it's 2x-y=6
Which means the answer is B.
Answer:
58 in^2
Step-by-step explanation:
The area of one face of the 3" cube is (3 in)^2 = 9 in^2. Then the 6 faces of that will have an area of ...
6·9 in^2 = 54 in^2
The area of the top of the paperweight is unaffected by the area of the added cube: the area the smaller cube covers is exactly the same as its exposed top area. So, the net effect of the added 1" cube is to increase the total area by that cube's lateral area: 4 faces at 1 in^2 for each face, a total of 4 in^2.
Then the total surface area of the paperweight is ...
54 in^2 + 4 in^2 = 58 in^2
200x+1500=total income per month
That can be factored as:
(x+5) * (x+4)
Therefore x = -5 and x = -4
