X = number of minutes Maria spends talking on the phone each month
y = Maria's monthly cost

If she talks for x minutes, at $0.01 per minute, then she is charged 0.01*x dollars for those x minutes. This is on top of the $39,99 as the flat fee (which is charged no matter how many minutes are used; even if Maria doesn't use her phone at all)

So that means we add 0.01*x to 39.99 to get 0.01*x+39.99
This expression is equal to y as it is the total cost for that month

Therefore y = 0.01*x+39.99 is the equation
If you want things in function notation, then you'd replace y with f(x) to get
f(x) = 0.01*x+39.99

miskamm [114]

Answer:

Step-by-step explanation:

a. use what's given in the question to write an equation

36x + 12y + 24e (using e as the variable for erasers)

b. 12 is the greatest common factor between the coefficients/ constant so factor it out

12 (3x + y + 2e)

12 kits

c. use the factored expression to see how many of each item

3x - 3 pencils

y - 1 crayon

2e - 2 erasers

mutiply the numerators together

(7x)(x)= 7x^ 2

mutiply the denominators together

(x-4)(x+7)

(x)(x)(7)(x)= x^2+7x

(-4)(x)(-4)(7)= -4x-28

x^2+7x-4x-28

x^2+3x-28

Answer:

7x^2/x^ 2+3x-28

The image shows a ray of light bending at the boundary of a glass block. According to a law of optics, = n, where n is a constan
Salsk061 [2.6K]
The law of optics applicable in this scenario is the Snell's Law which states that the ratio of the index of refraction of two media is equal to the ratio of the sine of the angle of reflection and sine of the angle of refraction. In equation form:
n₁ / n₂ = sin b / sin a
