Usually, you're asked to model a situation with an equation. Here, you're given the equation and asked what situation it models.

The features of the equation that are of interest are ...

  • multiplication of the unknown value by 17.35
  • comparison of that product to 624.60, expecting the product to be greater than that value

The first two offered scenarios involve addition of an unknown value, not multiplication.

The third offered scenario compares a purchase price to a budget amount. Answering a question like this involves a "less than" comparison, not a "greater than" comparison.

The last offered scenario involves finding a variable value that will result in the product 17.35x exceeding 624.60—exactly what the given inequality models.

The appropriate choice is ...

... J  Daren earns $17.35 ...

The price of a car has been reduced from $14,000 to $8,400. What is the percentage decrease of the price of the car?
Lady bird [3.3K]

Answer: 40%

Step-by-step explanation:

If you divide 8400 by 14000. You will see that $8400 is 60% (.60 in the calculator) you need to subtract that from 100 to find the discount. 100-60= 40

Answer:

y = -3x - 3

Step-by-step explanation:

First, determine the slope of the red line.  As we move from (0, 3) to (1, 0),

x increases by 1 and y decreases by 3.  Hence, the slope, m, is

m = rise / run = -3 / 1, or m = -3.

The desired new line, parallel to the red line, has the same slope as the red line:  m = -3.

The equation for this new line is y - k = m (x - h), where (h, k):  (-1, 0):

We get y - 0 = -3 (x + 1), or y = -3x - 3.

Check:  Does this line go thru the given point (-1, 0)?

Is 0 = -3(-1) - 3 true?  Yes, it is true.

The Tucker Gym charges a one time fee of $50 plus a $25 monthly membership
FinnZ [79.3K]

Answer:

y = 50 + 25x.............(i)

y = 80 + 15x.............(ii)

x = 3

y = 125

Step-by-step explanation:

The tucker Gym charges a one time fee of $50 plus a $25 monthly membership charge.  

The NoFo health club charges a one time fee of $80 plus a $15 monthly membership fee.

Let

number of month = x

total cost = y

Tucker Gym

y = 50 + 25x.............(i)

NoFo Gym

y = 80 + 15x.............(ii)

combining the equation

y = 50 + 25x.............(i)

y = 80 + 15x.............(ii)

y - 50 = 25x

y/25 - 2 = x

insert x in equation (ii)

y = 80 + 15(y/25 - 2)

y = 80 + 3y/5 - 30

y = 50  + 3y/5

y - 3y/5 = 50

5y - 3y/5 = 50

2y/5 = 50

cross multiply

2y = 250

y = 250/2

y = 125

insert y in equation (i)

125 = 50 + 25x

125 - 50 = 25x

75 = 25x

x = 75/25

x = 3
