Problem 7

Time is always an independent variable because time marches on doing its own thing without depending on external forces, or other people/things. Instead, other variables depend on time. In this case, the distance d depends on the independent variable t for time.

If the time goes up by 1 hour, then the distance variable goes up by 3 miles. In short, that tells us his speed is 3 mph.

Answer: Choice A) independent = time; dependent = distance

Problem 8

Everywhere you see an x, replace it with 9. Then use PEMDAS to simplify

f(x) = 5x - 9

f(9) = 5(9) - 9 ... x replaced with 9

f(9) = 45 - 9

f(9) = 36

Answer: 36

<h3>What is Algebra?</h3>

Algebra is the study of mathematical symbols and the rule involves manipulating these mathematical symbols.

Frances bought 144 shares of Dwyn horticulture for $7.73 apiece. her broker charged her a commission of $46.15 for the purchase.

Then the total amount spent by the company will be

→ 144 × $7.73 + $46.15 = $ 1159.27

If the yearly dividend on Dwyn horticulture is 61 cents per share, then the annual yield on Frances’s stock will be

$\Rightarrow \dfrac{0.61 \times 144}{11592.27} \\\\\Rightarrow 0.07577$
