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

The following angles are supplementary find the missing angle measure
nekit [7.7K]

Answer:

<em>x = 62°, y = 103°</em>

Step-by-step explanation:

<u>Supplementary Angles</u>

Two angles are called <em>supplementary</em> when their measures add up to 180 degrees.

The image shows two pairs of supplementary angles. We have to find the value of the unknown variable.

The first drawing shows supplementary angles x and 118°. They must satisfy the equation:

x + 118° = 180°

Subtracting 118°:

x = 180° - 118°

x = 62°

From the second drawing, we set up the equation:

y + 77° = 180°

Subtracting 77°:

y = 180° - 77°

y = 103°

1. Over 3 years, how much more does $3000 in a savings account with an APR of 3.2% compounded
Sedbober [7]

Answer:

$1080

Step-by-step explanation:

((3000 \times 0.032) \times 2) \times 3 = 576

convert % to decimal by multiplying 3.2%x100=0.032

then multiply by initial amount 3000x0.032

then multiply by 2 because it's compounding semiannual

then multiply by 3 because it's over a 3 yr period

do the same for the quarterly compound but multiply by 4 because it's quarterly

((3000 \times 0.03) \times 2) \times3 = 1080

over a 3 yr period the quarterly compounded amount will earn:

1080 - 576 = 504

$504 more than the account compounded semiannual
