Answer:
Step-by-step explanation:
Suppose J, K, L, M, N are points on the same line.
MK = MN + (-KN) = MN - KN = 9x - 11 - x - 3 = 8x - 14
Since LK = MK and LK = 7x - 10, then
7x - 10 = 8x - 14
8x - 7x = -10 + 14
x = 4
LJ = MK + KJ
MK = LK = 7x - 10 = 7(4) - 10 = 28 - 10 = 18
LJ = 18 + 28 = 46

<h2><u>
Answer:</u></h2>
x = 3
y = -8
<h2><u>
Step-by-step explanation:</u></h2>
x + y = -5
x - y = 11
Since the y's will cancel out, we don't need to modify the two equations in any way.
Now, just add the two equations.
x + x = 2x
y + (-y) = 0
-5 + 11 = 6
2x = 6
Divide by 2.
x = 3
To find y, plug 3 in as "x" in one of the two equations.
3 + y = -5
y = -8
Answer:
Step-by-step explanation:
Part A: What is the population in this survey?
The population in this context is the total number of registered voters in the whole city of San Diego.
Part B: What is the population parameter
The population parameter in this survey is the maximum percentage increase in municipal taxes that they would approve.
Part C: What is the sample in this survey?
The sample in this survey is the randomly selected 650 registered voters in the city.
So,
"7 more than"
7 +
"twice a number x"
2 * x or 2x
"7 more than twice a number x"
7 + 2x or 2x + 7
