why was the value of y for the function y =5x + 1 always be greater than that for the function y=4x+2 when x>1
Galina-37 [17]
Lets compare both equations so we can explain the reason for it, and see it clearly:
<span>y1 = 5x + 1 
</span><span>y2 = 4x + 2
y1 > y2
</span>5x + 1 > 4x + <span>2
</span>To see why that happens we need to solve for x:
5x - 4x > 2 - 1
x > 1
Therefore, the first equation is greater than the second for values of x > 1

Find the rectangular coordinates of the point with the polar coordinates ordered pair 7 comma 2 pi divided by 3.
Morgarella [4.7K]

Answer:

\left(-\dfrac{7}{2},\dfrac{7\sqrt{3}}{2}\right).

Step-by-step explanation:

The given point is

\left(7,\dfrac{2\pi}{3}\right)

We need to find the rectangular coordinates of the given point.

If a polar coordinate is (r,\theta), then  

x=r\cos theta

y=r\sin theta

In the given point \left(7,\dfrac{2\pi}{3}\right),

r=7,\theta=\dfrac{2\pi}{3}

Now,

x=7\cos \dfrac{2\pi}{3}

x=7\cos \left(\pi-\dfrac{\pi}{3}\right)

x=-7\cos \left(\dfrac{\pi}{3}\right)

x=-7\left(\dfrac{1}{2}\right)

x=-\dfrac{7}{2}

and,

y=7\sin \dfrac{2\pi}{3}

y=7\sin \left(\pi-\dfrac{\pi}{3}\right)

y=7\sin \left(\dfrac{\pi}{3}\right)

y=7\left(\dfrac{\sqrt{3}}{2}\right)

y=\dfrac{7\sqrt{3}}{2}

Therefore, the required point is \left(-\dfrac{7}{2},\dfrac{7\sqrt{3}}{2}\right).

Is knowing two sides and another angle enough to say they are congruent?
olga55 [171]
If there is more information then you should use it but if that is then yes it is possible if you think hard enough.

There would have been 3.25 or 3 1/4 pounds of candy eaten.
you would do 5 1/2 - 2 1/4 and get 3 1/4 .
