Which equation represents a parabola that opens upward, has a minimum at x = 3, and has a line of symmetry at x = 3?
Licemer1 [7]

Answer:

A. y = x^2 -6x + 13

Step-by-step explanation:

The parabola that opens up and has line of symmetry x=3 and a minimum at x=3  is

y=x^2-6x+13

The reason is that, we can write this function in the vertex form to get;

y=x^2-6x+(-3)^2+13-(-3)^2

y=(x-3)^2+13-9

y=(x-3)^2+4

Hence the line of symmetry is x=3 and the vertex is (3,4)

Donna took twice as long to drive 720 miles and Maple took to drive 200 miles. Find the rates and ties of both if Donna's speed
shepuryov [24]

Answer:

Donna traveled for 8 hours at 90 mph

Maple traveled for 4 hours at 50 mph

Step-by-step explanation:

The velocity at which each person traveled is given by the distance traveled divided by the time spent (t). From the information given, the following expressions can be written

t_d = 2t_m\\V_d = V_m+40\\V_d = \frac{720}{t_d}\\V_m = \frac{200}{t_m}\\\\V_d = \frac{360}{t_m}\\ \frac{360}{t_m}=\frac{200}{t_m}+40\\t_m = 4\ hours\\t_d=2*4 = 8\ hours\\\\V_d = \frac{720}{8}=90\ mph\\V_m = \frac{200}{4}=50\ mph\\

Therefore, Donna traveled for 8 hours at 90 mph and Maple traveled for 4 hours at 50 mph.

Diana received 300 votes in the election for student council president. That was 60% of the students who voted in the election.
Helen [10]

Answer:

500 students.

Step-by-step explanation:

300 votes is 60%.

100%-60% is 40%

so 40% voted for the other person.

Work backwards:

x * 0.6=300

0.6x=300

x=300/0.6 which is 500.

500*0.4 is 200.

300+200 is 500.

Hope this helps :) I am terribly sorry if it is wrong or not using the number line.
