Answer:

5) x = -1

6) x = 2

Step-by-step explanation:

5) 5 + 2x + 6 = x + 10

2x + 11 = x + 10

2x + 1 = x

1 = -x

-1 = x

6) (9x + 7) + (-3x + 20) = 39

6x + 27 = 39

6x = 12

x = 2

Answer:

For question 5, x= -1

Step-by-step explanation:

Segment Addition Postulate = ab+bc=ac

For Question 5,

(a) + (b) = (c)

5+2x + 6 = x+10

5+2x+6=x+10

To solve that,

5+2x+6=x+10

Add 5+6

11+2x=x+10

Subtract 11 from both sides

2x= x-1

x-1=2x

Answer:

The linear equation for the line which passes through the points given as (-1,4) and (5,2), is written in the point-slope form as $y=\frac{1}{3} x-\frac{13}{3}$ .

Step-by-step explanation:

A condition is given that a line passes through the points whose coordinates are (-1,4) and (5,2).

It is asked to find the linear equation which satisfies the given condition.

Step 1 of 3

Determine the slope of the line.

The points through which the line passes are given as (-1,4) and (5,2). Next, the formula for the slope is given as,

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Substitute 2&4 for $y_{2}$ and $y_{1}$ respectively, and $5 \&-1$ for $x_{2}$ and $x_{1}$ respectively in the above formula. Then simplify to get the slope as follows,

$m=\frac{2-4}{5-(-1)}$\\ $m=\frac{-2}{6}$\\ $m=-\frac{1}{3}$$

Step 2 of 3

Write the linear equation in point-slope form.

A linear equation in point slope form is given as,

$y-y_{1}=m\left(x-x_{1}\right)$

Substitute $-\frac{1}{3}$ for m,-1 for $x_{1}$ , and 4 for $y_{1}$ in the above equation and simplify using the distributive property as follows,

$y-4=-\frac{1}{3}(x-(-1))$\\ $y-4=-\frac{1}{3}(x+1)$\\ $y-4=-\frac{1}{3} x-\frac{1}{3}$$

Step 3 of 3

Simplify the equation further.

Add 4 on each side of the equation $y-4=\frac{1}{3} x-\frac{1}{3}$ , and simplify as follows,

$y-4+4=\frac{1}{3} x-\frac{1}{3}+4$\\ $y=\frac{1}{3} x-\frac{1+12}{3}$\\ $y=\frac{1}{3} x-\frac{13}{3}$$

This is the required linear equation.

Scientific notation of 1,304,000,000

svet-max [94.6K]

1.304 x 10⁰ = 1.304 x 1 = 1.304

1.304 x 10¹ = 1.304 x 10 = 13.04

1.304 x 10² = 1.304 x 100 = 130.4

1.304 x 10³ = 1.304 x 1,000 = 1,304

1.304 x 10⁴ = 1.304 x 10,000 = 13,040

1.304 x 10⁵ = 1.304 x 100,000 = 130,400

1.304 x 10⁶ = 1.304 x 1,000,000 = 1,304,000

1.304 x 10⁷ = 1.304 x 10,000,000 = 13,040,000

1.304 x 10⁸ = 1.304 x 100,000,000 = 130,400,000

* 1.304 x 10⁹ = 1.304 x 1,000,000,000 = 1,304,000,000 *
