Find the vertex of the graph y equal x to the power of 2 plus 6 x minus 5

Hello!

To find the vertex of a quadratic equation, use the formula x = -b/2a, and substitute that x-value into the original equation and solve for y. Also, for quadratics, the standard form for a quadratic is y = Ax² + Bx + C

Given equation: y = x² + 6x - 5

1. Use the formula: x = -b/2a

x = -6/2(1)

x = -6/2

x = -3

2. Substitute x = -3 into the given equation and solve for y

y = (-3)² + 6(-3) - 5

y = 9 + -18 - 5

y = -9 - 5

y = -14

Therefore, the vertex of the quadratic equation, y = x² + 6x - 5, is (-3, -14).

step-by-step explanation:

measurement of the swimming pool is given as = 7 yards 4.79 feet

first we will convert this to yards only.

1 foot = 0.33 yards

so, 4.79 feet = yards

so total yards are = yards

now we will convert this in meters.

1 yard = 0.914 meters

8.580 yards = meters

0.842 m = 0.842*100 = 84.2 cm

this becomes 7 meters and 84.2 cm

hence, the pool is 7 meters and 84.2 cm wide.
