Yes and they will always be coplanar.
Hey there!☺
Equation
−(2x+5)+14=22 Simplify both sides
−2x + −5 + 14 = 22 Distribute
(−2x) + (−5+14) = 22 Combine Like Terms
-2x + 9 = 22
-2x + 9 - 9 = 22 - 9 Subtract 9 from both sides
-2x = 13
-2x/-2 = 13/-2
-13/2 Add the negative to 13
x = -13/2
Hope this helps!
Answer:
2 proportions z test
The two populations are named as residents from the first county and residents from the second county.
Step-by-step explanation:
This is testing hypothesis about the difference between two proportions.
When the proportions are tested if they are the test statistic
z= ( p^1-p^2)- (p1-p2) / √p₁q₁/n₁ + p₂q₂/ n₂
where p^1 is the proportion of success in the first sample and p^2 of size n₁ is the proportion of success in the second sample of size n₂ with unknown proportions of successes p1 and p2 respectively.
When the sample sizes are sufficiently large
z= ( p^1-p^2)- (p1-p2) / √p₁q₁/n₁ + p₂q₂/ n₂ is approximately standard normal.
The two populations are named as residents from the first county and residents from the second county.
When g(x) = -30, x = -10
To solve, make -30 equal to 2(x-5):
-30 = 2(x-5)
-30 = 2x -10
-20 = 2x
-10 = x
X= 23+8y
X represents the total
23 represents the base price
8 represents the price per extra hour
Y represents how many hours extra
