Answer:
x intercept (3,0)
y intercept (0,-3)
Step-by-step explanation:
Answer:
Im sorry! idk the answer but if you have a phone, there is this app called photo math, or ask you mom or dad for help.
Step-by-step explanation:
The original price is $88.
how I got the answer:
$22 • 100= 2,200
2,000/25= $88
regular shoes cost w/75% off is $66.00
how I got my answer:
$88 • 75% = 6,600
6,600/100 = $66.00
If f(x)=x^2-8x-20 then
dy/dx=2x-8 and d2y/dx2=2
A) Since acceleration is a constant positive the parabola opens upward.
B) Since acceleration is a constant positive the parabola will have a vertex at an absolute minimum
C) The vertex will occur when dy/dx=0, 2x-8=0, 2x=8, x=4
So the axis of symmetry is the vertical line x=4.
The vertex is y(4)=-36, corresponding to the vertex point (4,-36)
The y-intercept occurs when x=0, y(0)=-20, so the y-intercept is the point (0,-20)
