The required equation of the line is y= 2x-5</h3><h3>
8.</h3><h3>
y=30</h3>
Step-by-step explanation:
Given , a line passes through the points (1,-3) and (3,1)
The equation of line which passes through the points and is
Here and
The required equation of the line is
8.
Given, y varies directly with x and y=24 when x=8
Therefore,
.........(1)
y = 24 when x=8
Equation (1) becomes
y= 3x
So, when x=10
y=3×10
⇒y=30
C = 36 pi units = 2 pi r. Thus, r = 36 pi / (2 pi) = 18 units.
Thus, A = pi*r^2 = pi*(18 units)^2

Answer:
The only algebraic expressions we can find here are the ones for the number of cards that Mr. Bates and Ms. Psenicska have.
We know that Mr. Nates has 3 packs of cards, plus 2 other cards.
If each pack of cards has N cards, then the total number of cards of Mr. Nates is:
Mr. Nates = 3*N + 2
And Ms. Psenicska has 6 packs plus other 8 cards, then she has a total of:
Ms. Psenicska = 6*N + 8
These two are the only expressions we can make with the given information.
