Answer: y=-\frac{1}{2} x+5

Step-by-step explanation:

We need to isolate y by itself

Step 1) Subtract 3x from both sides

3x+6y=30\\3x-3x+6y=30-3x\\6y=30-3x

Step 2) Divide both sides by 6 to isolate y

6y=30-3x\\\frac{6y}{6} =\frac{30}{6}-\frac{3x}{6}  \\y=5-\frac{1}{2}x

It is 90 ft between the bases of baseball diamond. A catcher throws a baseball to the shortstop who is half-way between second a
Hunter-Best [27]

Answer:

127.3 ft

Step-by-step explanation:

A baseball diamond is constructed in a square shape.

The sides are 90 ft each

If a catcher throws a baseball to the shortstop who is half-way between second and third bases, the distance between the third base and the short stop = 1/2(90)

= 45 ft

length of the throw is found using Pythagoras theorem.

Hypothenus ^2 = opposite ^2 + adjacent ^2

= 90^2 + 45^2

Hypothenus = √8100 + 2025

=√10125

= 100.62 ft (approximately)

[ALGEBRA 2 POLYNOMIAL DIVISION/REMAINDER THEOREM]
castortr0y [4]

Answer:

  k = -4

Step-by-step explanation:

The remainder theorem tells you that the remainder from division f(x)/(x -k) is f(k). You want the value of k such that ...

  f(k) = -15

Looking on the given graph, you find that k must be -4. That is, ...

  f(-4) = -15

  k = -4

_____

The divisor with k=-4 is (x -(-4)) = (x +4). The second attachment shows the division of f(x) by (x+4). The remainder is shown on the bottom line.

Answer:

5

Step-by-step explanation:

Let's first find the slope of the linear function represented by the table:

As we move from x = 4 to x = 6 *an increase of 2), y increases by 6 from -2 to +4.  Thus, the slope of this line is m = rise / run = m = 6/2, or 3.

Now we compare the two slopes:  -2 and 3.

The postive difference between them is 5.  This is Answer B.
