8 0

Square both sides

9(x + 2) = x + 4

Expand

9x + 18 = x + 4

Subtract x from both sides

9x + 18 - x = 4

Simplify 9x + 18 - x to 8x + 18

8x + 18 = 4

Subtract 18 from both sides

8x = 4 - 18

Simplify 4 - 18 to -14

8x = -14

Divide both sides by 8

x = -14/8

Simplify 14/8 to 7/4

Answer: 165 combination can be possible.

Step-by-step explanation:

Here, According to the question,

Different types of machines in the weight room in gym = 11

And, . Geoff has time to use only 3 of them this afternoon.

Therefore, total number of different combination of machine can geoff choose from to use

= $11_C_3$

= $\frac{11!}{3!\times (11-3)! }$ ( because $n_C_r = \frac{n!}{r!(n-r)!}$ )

= $\frac{11!}{3!\times 8! }$

= $\frac{11\times 10\times 9\times 8!}{6\times 8! }$

= $\frac{11\times 10\times 9}{6}$

= $\frac{990}{6}$

= $165$

Give the coordinates of a point on the line whose equation in point-slope form is.

pantera1 [17]

Answer:

(4, -2)

Step-by-step explanation:

The point-slope form of the equation for a line is ...

y -k = m(x -h)

for a line with slope m through point (h, k).

Comparing this to the equation you're given, you can see that the point that was used is (h, k) = (4, -2).

_____

You can find other points on the line, but this one is the easiest to find, since it can be read directly from the equation.

Describe how to write 7,594,000,000 in scientific notation. Complete the description. First move the decimal point places to the

s2008m [1.1K]

Step-by-step explanation:

The given number is 7,594,000,000.

To convert it into scientific notation,

First move the decimal point places to the left to find a number that is greater than or equal to 1 and less than 10. Then multiply by 10 , using an exponent on 10 that equals the number of places you moved the decimal. The exponent is negative if the original no was <1 and the exponent is positive, if the original number was > 1.

In 7,594,000,000, we move the decimal point places to the left before 5. It means we have moved 9 digits left.

Hence, $7,594,000,000=7.59\times 10^9$ is the scientific notation.
