Answer:
yes because the hours to distance is moving at a constant rate and if you were to graph it, it would also go through the origin

<u>Given function:</u>
<u>We can also write it as:</u>
x-intercept is the point where y = 0
Put y = 0 in the above equation
![0=x^2-7\\\\Add \ 7 \ to \ both\ sides\\\\7 = x^2\\\\Take \ sqrt \ on \ both \ sides\\\\\pm \sqrt{7} =x\\\\x = \pm \sqrt{7} \\\\\rule[225]{225}{2}](https://tex.z-dn.net/?f=0%3Dx%5E2-7%5C%5C%5C%5CAdd%20%5C%207%20%5C%20to%20%5C%20both%5C%20sides%5C%5C%5C%5C7%20%3D%20x%5E2%5C%5C%5C%5CTake%20%5C%20sqrt%20%5C%20on%20%5C%20both%20%5C%20sides%5C%5C%5C%5C%5Cpm%20%5Csqrt%7B7%7D%20%3Dx%5C%5C%5C%5Cx%20%3D%20%5Cpm%20%5Csqrt%7B7%7D%20%5C%5C%5C%5C%5Crule%5B225%5D%7B225%7D%7B2%7D)
A) x + 4y = -15
B) -2x -8y = 30
Multiplying A) by 2
A) 2x + 8y = -30
This has NO solution because A) and B) are actually the same equation.
Equation B = Equation A times minus 2.
A function that is defined on a sequence of intervals.
Step-by-step explanation:
Use the angle difference formula for cosine.
cos(α − β) = cos α cos β + sin α sin β
cos(180° − θ) = cos 180° cos θ + sin 180° sin θ
cos(180° − θ) = (-1) cos θ + (0) sin θ
cos(180° − θ) = -cos θ
