Answer:
B: No values of x make the equation true
Step-by-step explanation:
When you end up with -2 = -4
This is not true
That means there is no solution to the equation
Answer:
4
Step-by-step explanation:

Answer:
a = 4
b = -2
Step-by-step explanation:
If the given function is continuous at x = 1






And for the continuity of the function at x = 1,

Therefore, (a + b) = 2 -------(1)
If the function 'f' is continuous at x = 2,






Therefore, 
2a + b = 6 -----(2)
Subtract equation (1) from (2),
(2a + b) - (a + b) = 6 - 2
a = 4
From equation (1),
4 + b = 2
b = -2

Answer:
B. a decrease in their water bill of $3.16.
Step-by-step explanation:
Monthly service charge =$10.10
Volume charge = $1.58 for every 100 cubic feet of water.
Total monthly cost = 1.58x + 10.10
If the Johnson family used
less water this month than last month, then they can expect a reduction in their bill by the Volume charge for
.
Volume Charge per
of water = $1.58
Therefore: Volume Charge for
of water = 2 X $1.58=$3.16
Therefore, the Johnson family can expect a decrease in their water bill of $3.16.
