Mary is spending money at the average rate of $5 per day. After 14 days she has $68 left. The amount left depends on the number of days that have passed. write an equation for the situation
A. Y-68=-5(x-14) B. Y+68=5(x+14) C. Y+68=-5(x-14) D. Y+68=5(x-14)

Answers

Answer:

A. Y-68=-5(x-14)

Step-by-step explanation:

Mary is spending money at the average rate of $5 per day. After 14 days she has $68 left. The amount left depends on the number of days that have passed. write an equation for the situation

We find the equation using the point slope equation of a line. This is given as:

y - y1 = m(x-x1)

The slope intercept form will be

y = -5x + b

since the amount decreases by $5 per day...

Our slope is -5 so m=-5

We have a point (x1,y1) = (14, 68)

Hence, we have:

y-68 = -5(x-14)

Option A is correct

what does 10 = 4y equal to

Answers

69 ghcfhhggghjjohufdhhdjc

Answer:

Step-by-step explanation:

Simplifying

10 = 4y

Solving

10 = 4y

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-4y' to each side of the equation.

10 + -4y = 4y + -4y

Combine like terms: 4y + -4y = 0

10 + -4y = 0

Add '-10' to each side of the equation.

10 + -10 + -4y = 0 + -10

Combine like terms: 10 + -10 = 0

0 + -4y = 0 + -10

-4y = 0 + -10

Combine like terms: 0 + -10 = -10

-4y = -10

Divide each side by '-4'.

y = 2.5

Simplifying

y = 2.5

Find the angle of the least positive measure (in degrees, not equal to the given measure) that is coterminal with A.
A= -647°

Answers

9514 1404 393

Answer:

  73°

Step-by-step explanation:

A coterminal angle will be one that is this angle plus some multiple of 360°. We observe that the magnitude of the given value is between 360 and 720, so we can find the coterminal angle of interest by adding 720°.

  -647° +720° = 73°

The least positive measure angle coterminal with A is 73°.
