Step-by-step explanation:

set up the equation:

PQK+KQR=PQR

(14x-5)+(102)=(34x-3)

calculate the equation

you'll get x=5

put 5 into PQK

14(5)-5= 65

Find the missing value so<br> that the two points have a<br> slope of -13/2 (-2,y) and (0,-4
Art [367]

Answer:

y=9

Step-by-step explanation:

slope is (y2-y1)/(x2-x1), so we plug in the values. (-4-y)/(0 - (-2)). so we get -4-y/2 since zero minus negative 2 is positive 2. given the slope is -13/2, -4-y must be equal to negative 13. So we set an equation of -13 = -4 - y. We add 4 to 13, and get -9 = -y. We multiply each side by a -1, and we get y equals 9.

We can check this by plugging 9 back into our original slope equation. (-4-9)/(0-(-2) which gives us -13/2.

How many times does 6 go into 22
sergeinik [125]
Hey!

We can use long division to solve this,
Let's write it.
6\overline{|\smallspace22}\space\space\space\space
Then, divide 22 by 6 to get 3.
\begin{matrix}\space\space\space\space\space\space\emptyspace3\space\space\space\space\space\space\space\space\space\space\space\space\\ 6\overline{|\smallspace22}\space\space\space\space\space\space\space\space\space\space\space\space\end{matrix}
Multiply the quotient by the divisor...
\begin{matrix}\space\space\space\space\space\space\emptyspace3\space\space\space\space\space\space\space\space\space\space\space\space\\ 6\overline{|\smallspace22}\space\space\space\space\space\space\space\space\space\space\space\space\\ \space\space\space\space\underline{\emptyspace1\emptyspace8}\space\space\space\space\space\space\space\space\space\space\space\space\end{matrix}
Subtract 18 from 22.
\begin{matrix}\space\space\space\space\space\space\emptyspace3\space\space\space\space\space\space\space\space\space\space\space\space\\ 6\overline{|\smallspace22}\space\space\space\space\space\space\space\space\space\space\space\space\\ \space\space\space\space\underline{\emptyspace1\emptyspace8}\space\space\space\space\space\space\space\space\space\space\space\space\\ \space\space\space\space\space\space\emptyspace4\space\space\space\space\space\space\space\space\space\space\space\space\end{matrix}
As you can see, our answer using long division would be 3 with a remainder of 4. 

Thanks!

Solve each equation for 0° &lt; x &lt; 360°.
Ipatiy [6.2K]

Answer:

Hence value for x is 0 degree

Step-by-step explanation:

Given:

x limits are (0 to 360) degrees and

Cos(x+45)+cos(x-45)=Sqrt(2)

To Find:

value for X

Solution:

Given equation cos(x+45)+ cos(x-45)

Is similar to cos(A+B) +cos(A-B)=2cosA*cosB

Now comparing with general formula we get ,

A=x and B=45

S

Hence given equation becomes as ,

2cosA*cosB=Sqrt(2)

2Cosx*cos45=Sqrt(2)

cosx=Sqrt(2)/(2*cos45)..........cos45=1/\sqrt{2}

Cosx=Sqrt(2)/Sqrt(2)

cosx=1

x= 0

Hence value for x is 0 degree
