Answer:
93.33 miles
Step-by-step explanation:
60 min/ 20 min = 3
280/3 = 93.333333
The reflection is happening over the x axis (horizontal axis)
Any y coordinate that is positive turns negative, and vice versa
For example: (1,2) ---> (1,-2)
In general, the rule is (x,y) ---> (x,-y)
So the answer is choice C
Answer:
the answes are C and D
Step-by-step explanation:
Answer:
p = 3, q = 2.5
Step-by-step explanation:
Given that x = - 4 is a root of the equation, then
(- 4)² - 4p - 4 = 0, that is
16 - 4p - 4 = 0
12 - 4p = 0 ( subtract 12 from both sides )
- 4p = - 12 ( divide both sides by - 4 )
p = 3
Also given that the equation x² + px + q = 0 has equal roots
Thus the value of the discriminant b² - 4ac = 0
Here a = 1, b = p and c = q, thus
p² - 4q = 0 ← substitute p = 3 from above into the equation
9 - 4q = 0 ( subtract 9 from both sides )
- 4q = - 9 ( divide both sides by - 4 )
q = 2.5
