Answer:
-8, -10, -2 are your answers
Answer:
x
=
4
or
x
=
−
4
Explanation:
First divide throughout by
2
to get
x
2
=
16
Now take the square root on both sides to get
x
=
±
4
.
You may now substitute the values of
x
=
4
and
x
=
−
4
back into the original equation and check that it satisfies the equation which it does.
Step-by-step explanation:
Answer: Most of them cross each other once so I am not sure which one is the answer (sorry)
Step-by-step explanation:
x+y=7 is parallel to 3x+3y=3 and -6x-6y=3
3x+y=-1 and 6x+2y=-2 have infinite solutions togther (both are on top of each other)
The rest of the ways cross each other once
Answer:
7x - 8y = -23
Slope = 1.750/2.000 = 0.875
x - intercept = -23/7 = 3.28571
y - intercept = 23/8 = 2.87500
7x - 7y = -14
Slope = 1
x - intercept = -2/1 = -2.00000
y - intercept = 2/1 = 2.00000
Answer:
NQ = 9cm
Step-by-step explanation:
If you divide 24 with 6, you get 4. So I divide 36 with 4, which gave me 9.
