Answer:

7.25 × 10^6

Step-by-step explanation:

1) put into standard form: 6,000,000 + 1,250,000

2) add: 6,000,000 + 1,250,000= 7,250,000

3) put into scientific notation: 7.25 × 10^6

Answer:

3x -4y = -9

Step-by-step explanation:

Multiply by 4 to clear the fraction.

4(y -6) = 3(x -5)

Subtract the left-side term to get variables on the same side, with a positive x-coefficient.

0 = 3(x -5) -4(y -6)

Eliminate parentheses and collect terms.

0 = 3x -15 -4y +24

0 = 3x -4y +9

Subtract 9 and swap sides to get standard form.

3x -4y = -9

_____

Standard form is ...

ax +by = c

where a ≥ 0, and a, b, c are mutually prime integers. If a=0, then b > 0.

__

The attached graph shows the equations give the same line. The original line is shown dotted so that you can see they overlap.

Stella [2.4K]

Let $p$ represents the number of points scored in $n$ number of games.

So, the graph, the number of games, n is on the horizontal axis and the points scored, p, is on the vertical axis.

After Game 1, the point scored is 14,

so, the first point, $P_1$ , on the graph is

$P_1=(1,14)$

After Game 5, the point scored is 82,

so, the second point, $P_2$ , on the graph is

$P_2=(5,82).$

After Game 10, the point scored is 129,

so, the second point, $P_2$ , on the graph is

$P_2=(10,129)$

First, represent all the three points, $P_1, P_2$ and $P_3$ , on the graph, then connect $P_1- P_2$ and $P_2 - P_3$ as shown in the figure.
