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

Vikentia [17]

Answer:

3x^2y^2

Step-by-step explanation:

I think:

3*2*x*x*x*y*y*y*y

3*3*x*x*y*y

3*6*x*x*x*y*y

They all have 3x^2y^2 in common.

What is 1/8^2 as a negative exponent

ale4655 [162]

To rewrite with a negative exponent, reverse the fraction and change the exponent to a negative value:

Reversing 1/8 would be 8/1, which equals 8 and the exponent would become -2

The answer is 8^-2

What is the value of y?

maxonik [38]

Answer:- The value of y=6√3 units.

Explanation:-

Given: Δ TNM is a right triangle, where TN=y , NU=9 units ,UM=3 units, TM=6 units.

Now, we can see that NM=NU+UM

⇒NM=9 units + 3 units=12 units

As Δ TNM is a right triangle , then by Pythagoras theorem

$(Hypotenuse)^2=(Perpendicular)^2+(Base)^2\\\Rightarrow12^2=y^2+6^2\\\Rightarrow\ y^2=12^2-6^2\\\Rightarrow\ y^2=144-36=108\\\Rightarrow\ y=\sqrt{108}=6 \sqrt{3}$

Thus y=6√3units.

Pythagoras theorem states that in a right triangle the square of the longest side is equal to the sum of the squares of the other two sides.
