Answer:
D' (1, 3)
Step-by-step explanation:
When reflected across the y = x line, the "x" and "y" coordinates switch.
If D is (3, 1), then:
x = 3
y = 1
Switch the "x" and "y" values, and rewrite as (x, y).
x = 1
y = 3
D' (1, 3)
We know that
<span>the vertex form of the equation is
y=a(x-h)</span>²+k
we have
y = 7x² + 14x +4
y=7(x² + 2x) +4
y=7(x² + 2x+1-1) +4
y=7(x² + 2x+1) +4-7
y=7(x+1)²-3
the answer is
y=7(x+1)²-3
Answer:
Hello There!!
Step-by-step explanation:
Firstly,select three ordered pairs from the table. Secondly,substitute the first pair of values in to the form of the quadratic equation: f(x) = ax^2 + bx + c and then solve for a.
hope this helps,have a great day!!

Answer:
Hello Love! The median is simply just the number in the middle so sense we have 2 numbers in the middle our median will be 3 and 6
The mean is when you add up the numebers then divide by how many numbers there are so...
3 + 2 + 4 + 6 + 3 + 6 + 1 + 2 + 5 + 4 = 36 so 36 divided by 10 is 3.6
The range is simply just the biggest number in the sequence subtracted by the smallest number so... 6 - 1 = 5 so 5 would be our range!
Hope this helps you.
55/8 and in the decimal form it's 6.875
