Answer:
Distance is the square root of (x2-x1)to the second power-(y2-y1)to the second power
Step-by-step explanation:
Just look up distance formula
The only option that fits is E, because:
f(10)=4×10+10=50
7x - 3 = 5x + 5
-5x -5x
2x -3 = 5
+3 +3
2x = 8
x = 4
Given: <span>y = x^2 + 6x - 5. Then a = 1, b = 6 and c = -5.
The x-coord. of the vertex is given by x = -b / (2a), which here is x = -6 / (2*1) = -3.
Use the given formula </span><span>y = x^2 + 6x - 5 to find the value of y when x = -3:
y = (-3)^2 + 6(-3) - 5 = 9 - 18 - 5 = -14
Then the vertex is (-3, -14).</span>
