Which ordered pairs are in the solution set of the system of linear inequalities?

Mathematics

Fynjy0 [20]3 years ago

Answer with Step-by-step explanation:

The solution set of the system of linear inequalities are the ordered pair (x,y) which satisfy both the linear inequality or region which is common in both linear inequality.

The point (-4,2) doesn't satisfy both the inequalities

So, (-4,2) is not in the solution set

so, option first is incorrect

The point (4,-3) doesn't satisfy both the inequalities

So, (4,-3) is not in the solution set

so, option second is incorrect

The point (-3,1) doesn't satisfy the inequalities

So, (-3,1) is not in the solution set

so, option fourth is incorrect

Hence, correct option is:

Third: (5,-2), (3,1) and (4,2)

The cost of an uber ride, y, based on miles, x is represented by y = 2/3x + 4. How much does a 21-mile ride cost ?
dangina [55]

Answer:

Step-by-step explanation:

Let the cost of the Uber ride be represented by y in dollars.

Let the number of miles that the Uber rides be represented by x.

The equation relating x and y is expressed as

y = 2/3x + 4.

This is a slope intercept form equation. The slope is 2/3 and it represents the cost per mile.

The cost of a 21 mile ride will be

Substituting x = 21 into the given equation, it becomes

y = 2/3 × 21 + 4 = 14 + 4 = 18

The 21 mile ride costs $18

Part B) The $46 ride will cost

Substituting y = 46 into the given equation, it becomes

46 = 2x/3 + 4 =

46 - 4 = 2x/3

42 = 2x/3

2x = 42 × 3 = 126

x = 126/2 = 63

The $46 ride will be 63 miles

HELP ASAP PLEASEEEEEEEEEE
Andrew [12]

Given the recursive formula, each terms is five time the previous one.

This means that:

  • f(6) is 5 times f(5), which means f(6)=5f(5)
  • in turn, f(5) is 5 times f(4), so we have f(5)=5f(4). This means that f(6)=5f(5)=5\cdot 5f(4) = 25f(4)
  • Finally, f(4)=5f(3) So, substituting this back gives

f(6)=25f(4)=25\cdot 5f(3)=125f(3)

In general, since you have f(n)=5f(n-1), each time you compute a new term you multiply by a factor of 5, so if m=n+k, you have

f(m)=5^kf(n)
