3b=y+3x
To solve for B you need to put B before the equals sign
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>
C rational numbers
natural numbers are numbers like
1, 2, 3, 4 etc
whole numbers are numbers without a fraction or decimals (natural)
irrational is just bunch of random numbers
