Square rooting because you have to find the inverse of the equation to solve
Answer:
y = - 2x - 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ = (- 2, 2) and (x₂, y₂ ) = (1, - 4)
m =
=
= - 2, thus
y = - 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 2, 2), then
2 = 4 + c ⇒ c = 2 - 4 = - 2
y = - 2x - 2 ← equation of line
When we have exponents multiplied with the same base we add them so 5^5*5^10=5^15
Answer:
$4.1
Step-by-step explanation:
To find the Unit Rate, you have to find how much it cost of 1 lb. So, you have to divide 16 and 3.99
16/3.99
= 4.01002506
≈ $4.1
I believe that the answer is B. 62°
