Answer:
f(x) = - 2 (x + 2)² + 6
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (- 2, 6), thus
y = a(x - (- 2))² + 6, that is
y = a(x + 2)² + 6
To find a substitute the point (0, - 2) into the equation
- 2 = a(0 + 2)² + 6 ( subtract 6 from both sides )
- 8 = 4a ( divide both sides by 4 )
- 2 = a
f(x) = - 2(x + 2)² + 6 ← in vertex form
2800 + 0.08s = 3300 + 0.06s
0.08s = 0.06s = 3300 - 2800
0.02s = 500
s = 500 / 0.02
s = 25,000 <==
Answer:
87 3/4
Step-by-step explanation:
(7.1 + 16.04) - .2 = 22.94
hope i helped
can i have brainlist
The slope is -3 and the y-intercept is -7. The equation would be y = -3x – 7
