Answer:
(27,2) and (243,18)
(63,9) and (84,12)
(45,15) and (60,20)
(27,12) and (72,32)
(15,30) and (20,40)
(12,32) and (18,48)
(18,63) and (24,84)
Step-by-step explanation:
Formula for slope of a line is
a) (15,30) and (20,40).
Similarly find the slope of other lines.
b) (12,32) and (18,48).
c) (27,12) and (72,32).
d) (45,15) and (60,20).
e) (27,2) and (243,18).
f) (18,63) and (24,84).
g) (63,9) and (84,12).
After arranging the slopes in increasing order, we get
So, required arrangement of ordered pairs is
(27,2) and (243,18)
(63,9) and (84,12)
(45,15) and (60,20)
(27,12) and (72,32)
(15,30) and (20,40)
(12,32) and (18,48)
(18,63) and (24,84)
When the bases are the same, you can combine the exponents.
x³ [x is where the base is]
For example:
x³ · y² = x³y² You can't simplify this anymore because they have different bases/variables
[when you multiply a variable with an exponent by a variable with an exponent, you add the exponents together] so:
x² · x³ = 
[when you multiply a variable with an exponent by an exponent, you multiply the exponents together] so:
(x³)²=
That’s cool
Not sure how to answer this but I would like to help you just need to be more specific with your question
They will have the same coordinate,so we can just find out x and y
3x-y=9(1)
y=-2x+11(2)
Put (2) into(1)
3x-(-2x+11)=9
3x+2x-11=9
5x=20
x=4
Put x=4 into (1)
3(4)-y=9
12-y=9
y=3
Answer is A
Answer:
B.
• x+2y=-6
• x-2y=-6
Step-by-step explanation:
Try the solution in the equations and choose the set of equations that is true.
___
A. -6+0 ≠ 0 . . . not this system
__
B. -6 +2·0 = -6 . . . true
-6 -2·0 = -6 . . . true . . . . . this system has solution (-6, 0)
__
C. -6 -6·0 ≠ 1 . . . not this system
__
D. 4(-6)+3·0 ≠ -18 . . . not this system
