Answer:
x = -14
Step-by-step explanation:
x + 6 = 4x/7
7x + 42 = 4x
7x - 4x = -42
3x = -42
x = -42 ÷ 3
x = -14
Answer:
Step-by-step explanation:
domain is always the x-values, the first number of an ordered pair. and yes, the x and y values increase at a constant rate.
problem #1:
x / y
-2 -1
-1 -3
0 -5
1 -7
problem #4:
(5, 1) (6, 2) (7, -3) (8, 4) (9, 5)
hope this all helped ;)

Answer:
We are 95% confident that the average weight of the heaviest egg that is still medium size is 3.52 oz
Step-by-step explanation:
Mean = 3.2 oz, sd = 0.13 oz
Assuming there are 3 heavy eggs, n= 3, degree of freedom = n-1 = 3-1 = 2, t-value corresponding to 2 degrees of freedom and 95% confidence level is 4.303
Error margin = t×sd/√n = 4.303×0.13/√3 = 0.32 oz
Upper limit (heaviest egg that is still medium size) = mean + error margin = 3.2 + 0.32 = 3.52 oz
