Write an equation in point-slope form for each line (If possible please show work)

Mathematics
1 answer:
UkoKoshka [18]3 years ago
7 0

Answer:

y - 1 = -1(x + 1)

Step-by-step explanation:

I found where these points were on the graph. The slope of the line is -1. I used the x and y values from the points and the slope to make the equation above.

Take the y-value of one point and subtract it from y. Do the same thing to the x-values.

By the way, I used the second point to make the equation, but either point could have been used.

Someone plz help I rlly need to finish
bekas [8.4K]

Since TSQ and QSR are supplementary, they give 180 when summed. TSQ is 150, so QSR must be 30.

Therefore, you have

\tan(30)=\dfrac{\sin(30)}{\cos(30)}=\dfrac{\frac{1}{2}}{\frac{\sqrt{3}}{2}} = \dfrac{1}{2}\cdot\dfrac{2}{\sqrt{3}}=\dfrac{1}{\sqrt{3}}=\dfrac{\sqrt{3}}{3}

Please Help!!
expeople1 [14]

A = P(1 + rt)

Where:

<span>·         </span>A = Total Accrued Amount (principal + interest)

<span>·         </span>P = Principal Amount

<span>·         </span>I = Interest Amount

<span>·         </span>r = Rate of Interest per year in decimal; r = R/100

<span>·         </span>R = Rate of Interest per year as a percent; R = r * 100

<span>·         </span>t = Time Period involved in months or years

A = 15,000(1+ 0.07(5))

A = 20,250 they acquired in total for 5 years

The yearly amount the get is 15,000 xx 0.07 = $ 1050 per year

So in the next 25 years addition of 1050x25 = $26250 they will get
