Answer:
The slope is 
Step-by-step explanation:
-7-(-3)= -7+3= 4
4/?
7-(-9)= 7+9 = 16
4/16=1/4
I hope this helps :-)
First one is A
Second one is also A
the third one is also A!!!!
DA, AB, BC, CD
square, are side equal length and 90 degree angles
rectangle, two pairs of same length and 90 degree angles
parallelogram, two pairs of same length and two pairs of same angles
rhombus, all sides equal, two pairs of same angles.
yes, because they have the same length of all sides, same shape and same angles.
hope that helps! :D
If you take 2000 and divide it by 8 then it’s 250. Then you multiple it by 5 and you get 1250. So the answer is C) 1250.

Answer:
(x, y, z) = (-1, 0, -3)
Step-by-step explanation:
We notice that the coefficients of z are such that elimination of the z term from the equations is made easy.
Adding equations 1 and 2:
(2x -3y -2z) +(x +3y +2z) = (4) +(-7)
3x = -3
x = -1
Adding equations 2 and 3:
(x +3y +2z) +(-4x -4y -2z) = (-7) +(10)
-3x -y = 3
Substituting for x, we get ...
(-3)(-1) -y = 3
0 = y . . . . . . . . . . . add y-3 to both sides
Then z can be found from any equation. Substituting for x and y in the second equation gives ...
-1 +2z = -7
2z = -6 . . . . . add 1
z = -3 . . . . . .divide by 2
The solution is (x, y, z) = (-1, 0, -3).
Step-by-step explanation:
Four friends all give each other presents. The total cost of the presents is £80.52. We need to find the mean cost of a present in pounds. So, the mean cost of a present is equal to 20.13 .
