X - y = -3
y = x + 3.......slope = 1, y intercept = (0,3)
to find x int, sub in 0 for y and solve for x
x - y = -3
x - 0 = -3
x = -3....so the x intercept = (-3,0)
plot ur points (0,3) and (-3,0)......now start at (-3,0)....and since ur slope is 1, go up one, and to the right 1, and up 1, and to the right 1.....do this over as many times as needed and u should cross the y axis at (0,3)
A.
The rate is 12:2
B.
Set up a proportion:
12/2 = x/5
Multiply 5 to both sides:
60/2 = x
Divide:
30 = x
So he will walk 30 miles in 5 hours.
C.
To find out, we can divide 12 / 2.
12 / 2 = 6 miles per hour
The answer is: " h = A / b " .

Explanation:
_________________________________________________________
Given: " A = bh " ; Solve for "h" ;
_________________________________________________________
A = bh ;
↔ bh = A ;
Divide each side of the equation by "b" ; to isolate "h" on one side of the equation; & to solve for "h" ;
→ (bh) / b = A / b ;
to get:
→ h = A / b .

The answer is: " h = A / b " .

Answer:
$23,330.66
Step-by-step explanation:
The compound interest function is ...
FV = P(1 +r/n)^(nt)
where P is the principal amount ($19,600), n is the number of compoundings per year (4), r is the interest rate (.035), and t is the number of years (5).
Putting these numbers into the formula and doing the arithmetic, we get ...
FV = $19,600(1 +.035/4)^(4·5) = $23,330.66
Answer:
Infinitely many solutions
Step-by-step explanation:
-5.9x - 3.7y = -2.1
5.9x + 3.7y = 2.1
If we add these two equations together, -5.9x cancels out 5.9x, -3.7y cancels out 3.7y, and -2.1 cancels out 2.1.
This leaves us with:
0 = 0
Since this is true, that means there are infinite solutions.
