Answer:
D.
Step-by-step explanation:
Cassidy’s family is driving home from vacation at an average speed of 55 mph.
Initially, at x = 0 hours, the family is y = 0 miles away form home. We get the first point (0,0).
After x = 2 hours, the family is y = 110 miles from home. We get the second point (2,110).
The equation in point-slope form that represents their distance y from home, after x hours is
$9.50 plus sales tax would be $0.95 so $10.45
Answer:
Given Two equations :-
- multiplying eq.(i) by 2 eq.(ii) by 3.
- <u>placing this value of y² in eq. (i)</u>
3x²- 2×9 = 57
3x² - 18 = 57
3x² = 57 + 18
3x²= 75
x² = 25
<u>x = ± 5</u>
<h3>So, the values of x are <u>+5 and -5</u> </h3><h3>and the values of y are
<u>+3 and -3</u></h3>
