Answer: x-intercept
<u>Step-by-step explanation:</u>
NOTES
1) Parabolic motion is represented by the equation:
h(t) = -9.8t² + vt + h (in meters per second²), v is velocity
or
h(t) = -32t² + vt + h (in feet per second²), v is velocity
2) The x-axis is time (in seconds) & the y-axis is height (in meters or feet).
Since you want to know what time the object hit the ground, h = 0
Therefore, you are looking for the zero of the equation, which is on the x-axis, thus is the x-intercept.
We see that the slope intercept is y = 8x - 20. So if we substitute x with 2, because x represents the amount of necklaces sold and we are analyzing her net profit after selling 2 necklaces, that gives us y = 8(2) - 20. Which simplifies to y = -4. So by the time Jocelyn sells 2 necklaces, her net profit will be at -4.
I guess it would be true because 100+95+85+80 = 360, and there are 360 degrees in a circle.
Answer:
the solution is (-1, 2)
Step-by-step explanation:
Let's solve the system
(3x + 4y = 5)
(2x - 3y = -8)
using the method of elimination by addition and subtraction. Notice that if we multiply all terms of the first equation by 3 and all terms of the second by 4, y as a variable will temporarily disappear:
9x + 12y = 15
8x - 12y = -32
-----------------------
17x = - 17, so x = -1.
Replacing x in the second equation by -1, we get:
2(-1) - 3y = -8, or
2 + 3y = 8,
or 3y = 6. Thus, y = 2, and the solution is (-1, 2).
Answer:
3/16 or 0.1875
Step-by-step explanation:
3/4 - ((3/8)/2/3))
= 3/4 - 3/8 * 3/2
= 3/4 - 9/16
= 12/16 - 9/16
= 3/16 or 0.1875
Hope this help you :3
