<Q and <R are complementary angles. If m<Q = (31 - 3x)° and m<R = (19x - 5)°, find m<R​
Amanda [17]

31-3x+19x-5=90

26+16x=90

-26 -26

--------------------

16x= 64

16x/16= 64/16

x=4

m <R=19 (4)-5= 71.

703.36  either might be in your answer list.

Step-by-step explanation:

Givens

r = 8 inches

rotations = 14

Formula

D = 14*C where C = 2 pi r

Solution

D = 14 * (2 pi * 8)

D = 224 * pi                                    One possible answer

D = 224 * 3.14  = 703.36 inches    Another possible Answer

Answer:

Option D that is y=-2(x+1) is the correct choice.

Explanation:

Given equation:

y=2x-2

We have to find another equation which has only one solution.

Standard form of equation:

1.a_1x+b_1y+c_1=0

2.a_2x+b_2y+c_2=0

Condition for one solution.

\frac{a_1}{a_2} \neq \frac{b_1}{b_2}

We have to arrange other equation in the form of  ax+by+c=0

Mark all the options as a,b,c and d.

a.\ 2x+1-y=0

b.\ 2x-2-y=0

c.\ 2x-4-y=0

d.-2x-2-y=0

Now from the above options we can see that option a,b\ and\ c are not providing the desired result.

So

\frac{a_1}{a_2} \neq \frac{b_1}{b_2} can be obtained from the last option.

As

\frac{a_1}{a_2} \neq \frac{b_1}{b_2} ,\frac{2}{-2} \neq \frac{-1}{-1} ,-1\neq 1

Option D that is y=-2(x+1) is the equation from where we can obtained only one solution.
