Answer:
x = 2, y= 3
Step-by-step explanation:
y = -2x+7
y = 5x-7
Since the equations are both equal to y, set them equal to each other
-2x+7 = 5x-7
Add 2x to each side
-2x+7 +2x= 5x+2x-7
7 = 7x -7
Add 7 to each side
7+7 = 7x
14 = 7x
Divide by 7
14/7 = 7x/7
2 = x
Now find y
y = 5x-7
y = 5*2 -7
y = 10-7
y =3

Given:
3n + 5
n = 1 ; 3(1) + 5 = 3 + 5 = 8
n = 2 ; 3(2) + 5 = 6 + 5 = 11
n = 3 ; 3(3) + 5 = 9 + 5 = 14
n = 4 ; 3(4) + 5 = 12 + 5 = 17
The first four terms of the sequence are: 8, 11, 14, 17. Second option.

Step-by-step explanation:
Given a mean of 32. The claim here is that the mean is 32.
Therefore, the null hypothesis and alternative hypothesis, would be:
H0 : u = 32
Ha: u ≠ 32
b) When we fail to reject null hypothesis, H0. This means that the mean weight, u = 32
Conclusion: There is not enough evidence to conclude that there is overfilling or underfilling.
c) When null hypothesis, H0 is rejected. This means the mean weight, u ≠ 32.
Conclusion: There is enough evidence to conclude that overfilling or underfilling exists
