2.19 • 10^8. You first make a number in between 1-10, so it would be 2.19, then you count how many 0s there are behind your numbers and how many numbers are behind the decimal point, so that would be 6 0s and 2 numbers behind decimal point so then you get 10^8.

1/3 ( x - 10) = -4 ???

Pepsi [2]

Answer:

$x = - 2$

Step-by-step explanation:

1) Simplify 1/3 ( x - 10) to x-10/3.

$\frac{x - 10}{3} = - 4$

2) Multiply both sides by 3.

$x - 10 = - 4 \times 3$

Simplify 4 × 3 to 12.

$x - 10 = - 12$

4) Add 10 to both sides.

$x = - 12 + 10$

5) Simplify -12 + 10 to -2.

$x = - 2$

So, therefor, the answer is, x = -2.

Find the distance between the points ( – 9, – 4) and ( – 4,8).

Dmitriy789 [7]

Answer:

$Distance=13\ units$

Step-by-step explanation:

<u><em>Distance between two points:</em></u> Distance between two pints $(x_1,y_1)\ and\ (x_2,y_2)$ is given by

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Distance between $(-9,-4)\ and\ (-4,8).$

$d=\sqrt{(-4-(-9))^2+(8-(-4))^2}\\\\d=\sqrt{(-4+9)^2+(8+4)^2}\\\\d=\sqrt{(5)^2+(12)^2}=\sqrt{25+144}\\\\d=\sqrt{169}\\\\d=13$
