I'm pretty sure that you answered it correctly. 10-U
Answer:
Step-by-step explanation:
Given
Solving (a): An equivalent inequality
We have:
Multiply both sides by -1 (this changes the inequality)
Solving (b): Values of u from least to greatest
implies that u ends at -4, starting from negative infinity
So, the list is:
The answer is A. It is not B because 9 is the product of 3 x 3. It can't be C because 1 is only the product of 1 x 1.
Answer:
Step-by-step explanation:
Since you have
+
5
y
in one equation and
−
5
y
in the other equation, you can add both equations to cancel out the y terms and solve for x.
−
6
x
+

x
=

x
5
y
−
5
y
=
0
1
+
10
=
11
therefore
−
x
=
11
multiplying both sides by -1:
x
=
−
11
plugging this back into the first equation:
−

(
−
11
)
+
5
y
=

66
+
5
y
=
1
subtracting 66 from both sides:
5
y
=
−
65
divide both sides by 5:
y
=
−
13
putting the x-values and y-values into one point gives:
(
−

,
−
13
)
as the solution
