Could someone help me? the video doenst explain it

True [87]

Personally, I would recommend reading this as a fraction, and splitting up mantissa from the power of 10. (Mantissa refers to the number 1.23 in $1.23\times10^n$ .)

$\left(3.6 \times 10^{-5}\right) \div \left(9 \times 10^{-7}\right) = \dfrac{3.6 \times 10^{-5}}{9 \times 10^{-7}} = \dfrac{3.6}9 \times \dfrac{10^{-5}}{10^{-7}}$

Now just reduce each fraction:

$\dfrac{3.6}9 = \dfrac{36}{90} = \dfrac25 = 0.4$

$\dfrac{10^{-5}}{10^{-7}} = 10^{-5-(-7)} = 10^{-5+7} = 10^2$

So

$\left(3.6 \times 10^{-5}\right) \div \left(9 \times 10^{-7}\right) = 0.4 \times 10^2 = \boxed{4 \times 10^1}$

since $0.4\times10^2 = 0.4 \times 100 = 40 = 4 \times 10$ .

Determine whether each ordered pair is a solution of y = 3x-5. (2,2) (4,7) (6,13) (5,10)

cestrela7 [59]

Answer:

(4,7), (6,13), and (5,10)

Step-by-step explanation:

To determine if an ordered pair is a solution, substitute the coordinates in and check to see if they are true:

(2,2)

$y=3x-5\\(2)\stackrel{?}{=}3(2)-5\\2\stackrel{?}{=}6-5\\2\neq1$

Thus, (2,2) is not a solution.

(4,7)

$y=3x-5\\(7)\stackrel{?}{=}3(4)-5\\7\stackrel{?}{=}12-5\\7\stackrel{\checkmark}{=}7$

Thus, (4,7) is a solution.

(6,13)

$y=3x-5\\(13)\stackrel{?}{=}3(6)-5\\13\stackrel{?}{=}18-5\\13\stackrel{\checkmark}{=}13$

Thus, (6,13) is also a solution.

Lastly, (5,10)

$y=3x-5\\10\stackrel{?}{=}3(5)-5\\10\stackrel{?}{=}15-5\\10\stackrel{\checkmark}{=}10$

Thus, (5,10) is also a solution.
