Answer:

y = -x -2

Step-by-step explanation:

We can find the slope by using 2 points

m = (y2-y1)/(x2-x1)

  = (-3-0)/(1--2)

  = -3/(1+2)

   = -3/3

   = -1

The y intercept is when x=0  The y intercept is -2

y = mx + b where m is the slope and b is the y intercept

y = -x -2

Answer:

y= -x-2

Step-by-step explanation:

y=ax+b

x= -2; y=0 => 0=-2a+b; b=2a

x= -1; y= -1 => -1=-a+b => b=a-1

2a=a-1=> a= -1; b= -2

=> y= -x-2

Consider the universal relation r = {a, b, c, d, e, f, g, h, i, j} and the set of functional dependencies f = { {a, b } → {c}, {
nekit [7.7K]

Answer:

relation of FDs are {a, b, d, h}. From these all but {h}

seem plausibly part of keys. Calculating the closures of likely candidates gives:

{a, b} + = {a b, c, i}

{b, d} + = {b, d, e, f}

{a, d} + = {a, d, g, h, i, j}

{a, b, d} + = {a, b, c, d, e, f, g, h, i, j}  

decompose r into 2nf and then 3nf relations shown in attachment.                    

Step- by-Step Explanation

Explanation is given in the attachment.

Solve 5 + 44 = 2 + r
pickupchik [31]
Okay the answer is r=47
Let's solve your equation step-by-step.<span>5+44=2+r
</span>Step 1: Simplify both sides of the equation.<span>5+44=2+r
</span>Simplify:<span>49=r+2
</span>Step 2: Flip the equation.<span>r+2=49
</span>Step 3: Subtract 2 from both sides.<span><span>r+2−2</span>=49−2</span>r=47
Answer:<span>r=<span>47
Hope this helps!:)</span></span>
