Hitung jarak di antara titik P(7, 1) dengan titik Q(7, 8) ​
MaRussiya [10]

Answer:

7 units

Step-by-step explanation:

Distance between 2 points

=\sqrt{(y1 - y2)^{2}  + (x1 - x2) {}^{2} }

Thus, distance PQ

=\sqrt{(8 - 1)^{2}  + (7 - 7)^{2} }  \\ = \sqrt{7^{2} }  \\  = 7

Or you could simply take 8-1= 7 since both points have the same x-coordinate. Thus, PQ is a vertical line and the distance between them is due to the difference in their y-coordinate.

8. Solve this system of equations
Leya [2.2K]

Answer:

A) x = − 1, y = 2, z = 3

Step-by-step explanation:

4x − 2y + 3z = 1

x + 3y − 4z = −7

3x + y +2z = 5

Lets eliminate x by multiplying the second equation by -4

4x − 2y + 3z = 1

-4x - 12y + 16z = 28

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

-14y +19z = 29

Lets eliminate x by multiplying the second equation by -3

-3x + -9y +12z = 21

3x + y +2z = 5

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

          -8y +14z  =26

We now have 2 equations and 2 unknowns

-14y +19z = 29

-8y +14z = 26  Divide this by 2   = -4y +7z = 13

Multiplying the first equation by 4 and the second by -14

-56y +76z =116

56y -98z = -182

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

-22z =-66

Divide each side by -22

-22z/-22 = -66/-22

z=3

Now we need to find y

-14y +19z = 29

-14y +19(3) =29

-14y+ 57 = 29

-14y =29-57

-14y =-28

y =2

Now we need to find x

x + 3y − 4z = −7

x + 3(2) -4(3) =-7

x+6 -12 =-7

x-6 = -7

x = -1
