Answer:
The graph is attached below.
Step-by-step explanation:
First, we want to isolate the "x" term from the equation. We do this by subtracting "2" from both sides.
This gives us x is greater than -1. So, we can graph:
Answer:
There are 6 nickels, 10 dimes and 13 quarters.
Step-by-step explanation:
number of nickels = n
number of dimes = n+4
number of quarters = (n+4)+3 = n+7
express total amount in cents $4.55 = 455 cents
express total in cents by multiplying quantities of coins by value and adding them up.
455 = 5*n + 10*(n+4) + 25*(n+7) 455 = 5n + 10n + 40 + 25n + 175 240 = 40n n = 6
so number of nickels = 6.
number of dimes = number of nickels + 4 = 6+4 =10
number of quarters = number of dimes + 3 = 10+3 = 13
There are 6 nickels, 10 dimes and 13 quarters.
Answer:
11 units
Step-by-step explanation:
Let's do it this way:
Length = l
width = w
initial equation for area is l * w
We know that l = w+5
substitute.
w+5 * w = 36
solve.
6w = 36
w=6
The width is 6 units.
6+5 = 11
length = 11 units
Answer:
-1
Step-by-step explanation:
slope = y2-y1/x2-x1
(5,5) (7,3)
slope = 5-3/5-7 = 2/-2 = -1
