The house's value increased by $49,970. The current value of the house is $312,970.
Step-by-step explanation:
Step 1:
The house was valued at $263,000 and this value increased by 19%. So we need to calculate how much 19% of $263,000 is.
To do so we convert the 19% into a fraction by dividing it by 100 and multiplying it with the house's value.
19% of $263,000 = 
So the value of the house increased by $49,970 in several years.
Step 2:
To calculate the current value, we add the increased value to the original value.
The current value = the past value + The increased value,
The current value 
So the current value of the house is $312,970.
Answer:
The slope of AB is -5.
Step-by-step explanation:
Parallel lines copy the same slope, so if CD and AB are parallel lines, they will both have the same slope of -5.
16. (x-5)(x+4) = x^2-x-20
17. 2x>7 = x=3.5
18. -4
Let the consecutive even integers be x and (x+2).
x + (x + 2) = 106
2x + 2 = 106
2x = 104
x = 52
Thus the two integers are 52 and 54.
