Answer:

Step-by-step explanation:
Move all terms to the left side and set equal to zero. Then set each factor equal to zero.
Answer:
y = (4/3)x - (22/3)
Step-by-step explanation:
If it's parellel than they have the same slope.
m = 4/3
y = mx + b
y = (4/3)x + b
2 = (4/3)(7) + b
(6/3) = (28/3) + b
-(28/3) -(28/3)
(-22/3) = b

You need to do 1525/15 which equals roughly 101.6 and go to the nearest answer given :)
Answer:
y = 3x² + 54x + 240
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) = (- 9, - 3), thus
y = a(x + 9)² - 3
To find a substitute either of the roots into the equation
Using (- 8, 0), then
0 = a(- 8 + 9)² - 3
0 = a - 3 ( add 3 to both sides )
a = 3
y = 3(x + 9)² - 3 ← in vertex form
Expand factor and simplify
y = 3(x² + 18x + 81) - 3
= 3x² + 54x + 243 - 3
= 3x² + 54x + 240 ← in standard form
Answer:
A
Step-by-step explanation:
Focus on what the question is telling you, as it's given to you in the question. It's saying five times, which means "×5" the number of person B, so it'll always be 5 times quicker, since they're breathing more times in a certain period of time than person B.
Hopefully this helped!
