Answer:

The Answer is: y = 2x - 3

Step-by-step explanation:

Given points: (3, 3) and (4, 5)

Find the slope, m:

m = y - y1/(x - x1)

m = 3 - 5/(3 - 4)

m = -2/-1 = 2

Use the Point Slope form of the equation:

y - y1 = m(x - x1)

y - 5 = 2(x - 4)

y - 5 = 2x - 8

y = 2x - 8 + 5

y = 2x - 3

Proof:

f(3) = 2(3) - 3

= 6 - 3 = 3, giving (3, 3)

Answer:

Step-by-step explanation:

Solve by doing y-y1 Over

x-x1 to find m. Pick either set of points and set up the equation as y=mx+b. So if you were to pick 3,3 as your set of points you would set up the equation like this: 3=m(that’s what you find earlier in the problem) (3) +b. Hope this helps in not good at explaining

This is just another way of asking "what is the volume of a sphere of 6cm"
The volume of a sphere is $V= \frac{3}{4} \pi R^{3}$
The R is 3cm in this problem since the diameter is twice the radius. For a 3cm radius sphere this is 113.1cm^3

marusya05 [52]

Let R=A AND (NOT B)] OR (NOT B)
If A=T, B=T
then ~B=F,
A and ~B = F
So R=F
If A=T,
B=F ~B=T
A and ~B=T
so (A and ~B) or ~B = T etc.
