A. The LCD is (n+1)(n-2)
B. n = -1, n = 2
C. n = negative 1 plus or minus the square root of 73, everything divided 2.
I’ve add a picture of the answers at the bottom in case I wasn’t clear on question C.
Hope that helps.
Answer: y = 2x+22
========================================================
Explanation:
The equation y = 2x+5 is in the form y = mx+b
m = 2 = slope
b = 5 = y intercept
Parallel lines have equal slopes, but different y intercepts. So the answer will be in the form y = 2x+c, where b and c are different numbers. Since b = 5, this means c must be some other number. If c = 5, then we'd have the exact same line.
Let's plug in (x,y) = (-5,12), along with the slope m = 2, and solve for c
y = mx+c
12 = 2(-5)+c
12 = -10+c
12+10 = c
22 = c
c = 22
Since m = 2 and c = 22, we go from y = mx+c to y = 2x+22
The equation of the parallel line is y = 2x+22
The graph is below.
Answer : b. $65.10
1 appetizer: $7.39=7.39
2 entrees: $16.99 each= 2 * 16.99=33.98
1 dessert: $5.29= 5.29
2 drinks: $2.30 each=4.6
cost = 7.39 + 33.98 + 5.29 + 4.6 =$51.26
7% tax = 51.26 * 0.07 = 3.5882
20% gratuity = 51.26 * 0.2= 10.252
Total cost = 51.26 + 3.5882 + 10.252 =65.1002
the total amount = $65.1
