Step-by-step explanation:
Answer:
- She traveled 45 miles in 1 hour
- She traveled 270 miles in 6 hours
- She traveled 360 miles in 8 hours
Step-by-step explanation:
If Mrs. Anglin traveled at a speed of 90 miles in 2 hours, it means that her speed per hour is:
= 90/2
= 45 mph
If she is travelling at 45mph then in 1 hoour she would have traveled 45 miles.
In 6 hours she would have traveled:
= 45 * 6
= 270 miles
In 8 hours she would have traveled:
= 45 * 8
= 360 miles
<span>The general equation of a quadratic is expressed as y = ax^2+bx+c. To
convert the general equation to vertex form, we need to obtain this form:
(y- k)= a(x - h)^2
This could be done by using completing the square method.
</span><span>y = –3x^2 – 12x – 2
</span><span>y + 2 = –3(x^2 + 4x)
</span>y + 2 -12 <span>= –3(x^2 + 4x + 4)
</span>y - 10 = -3(x+2)^2
Therefore, the answer is the first option.
The answer is 2x+9+4 over x-2
