Find the slope of the line that passes through the points (-12,10) and (-18,14).

9966 [12]

Answer:

-2/3

Step-by-step explanation:

To find the slope we use the formula

m= ( y2-y1)/(x2-x1)

= ( 14-10)/(-18- -12)

= (14-10)/(-18+12)

= 4/-6

= -2/3

The range of a data set is the greatest value minus the smallest value.

The greatest value here is 32, and the smallest value is 27:

$\sf Range=32-27=\boxed{\sf 5}$

HELP MEE PLZZZZ I DON'T UNDERSTAND THIS

Damm [24]

Answer: Choice D. $6.44 \times 10^{-4}$

========================================================

Work Shown:

We multiply the coefficients 9.2 and 7 to get 64.4, which is the same as 6.44*10^1 in scientific notation. When multiplying exponential expressions with the same base, we add the exponents

This is what the steps could look like

$\left(9.2 \times 10^{-9}\right)\times\left(7 \times 10^{4}\right)\\\\\left(9.2\times7\right)\times\left(10^{-9} \times 10^{4}\right)\\\\\left(64.4\right)\times\left(10^{-9+4}\right)\\\\\left(6.44\times 10^{1}\right)\times\left(10^{-5}\right)\\\\6.44\times\left(10^{1}\times 10^{-5}\right)\\\\6.44\times\left(10^{1+(-5)}\right)\\\\6.44\times 10^{-4}\\\\$

The final result is in scientific notation as the coefficient c is restricted such that $0 \le c < 10$
