The numerator and denominator must be polynomials so
the answer to your question is - 7x / x^2 ( the last one on the right)
Answer:
y=-3x-3
Step-by-step explanation:
9x+3y=-9
This is currently in standard form, or ax+by=c.
To get it to slope-intercept form, (y=mx+b) first subtract 9x to both sides.
3y=-9x-9
Divide both sides by 3.
y=-3x-3
Answer:
2 Hours
Step-by-step explanation:
4/7 of an hour = 34.3 minutes.
34.3 minutes per 2/7
4/7 = 68.6 OR 1 hour 8 minutes.
6/7 = 102.9 OR 1 hour 42 minutes.
Then add half of 34.3 (17.15)
7/7 = 120.05. = 2 hours 0.5 seconds.
If the diameter of the circle is 17.4 cm, the approximate circumference of the circle would be 54.636. If the radius of the circle is 17.4 cm, the approximate circumference would be 109.272.
Explanation:
Circumference of a circle = Pi (3.14) x diameter
In this case, the diameter (I am assuming) is 17.4, so in order to solve the circumference you must multiply Pi by 17.4.
(If 17.4 is the radius, simple multiply 17.4 by 2 and then solve for the circumference like you normally would. You must multiply the radius by two because the radius is half of the circles circumference.
Hope that helps. Happy learning!
Answer:
<h3>-cos10°</h3>
Step-by-step explanation:
cos is positive at first and fourth quadrant
so, cos (-x) = cos (x)
also, cos(180-x) = -cos x
cos (180+x) = -cos x
cos (-170°) = cos (170°)
cos(170°) = cos (180° - 10°)
= - cos 10°
