Which point is a solution of x + 2y ≤ 4?(2, 4)

(1, 1)

(3, 5)

(-1, 5)

Answers

Answer 1

Answer:

Answer:

The point that is a solution of x + 2y ≤ 4, is (1,1)

Step-by-step explanation:

Given x + 2y ≤ 4, to teste if a point is a solution of the inequation you have to replace each par of values in the inequation and see the result.

So,

(2,4) ⇒ 2 + 2·4 ≤ 4 ⇒ 8 ≤ 4, this is not correct.

(1,1) ⇒ 1 + 2·1 ≤ 4 ⇒ 3 ≤ 4, is correct.

(3,5) ⇒ 3 + 2·5 ≤ 4 ⇒ 13 ≤ 4, this is not correct.

(-1,5) ⇒ -1 + 2·5 ≤ 4 ⇒ 9 ≤ 4, this is not correct.

Summarizing the only point that is solution of x + 2y ≤ 4, is (1,1)

Answer 2

Answer: (1,1) because x + 2y <4
=1 + 2(1)
= 3 which is less than 4

C) 0.36 and 3.6%
D) 0.036 and 0.36%

Answers

B) 0.36 and 36%

just divide 9 by 25 to get the answer,

you will get 0.36 when doing this and just convert it into a percent

then boom you get 0.36 and 36 %

consider the following systems of equations y=3x-7 y-3x=5 what can you conclude about the system of equations

Answers

Take the second equation [ y - 3x= 5 ] and add 3x to each side: [ y = 3x + 5 ].

Now you can see that the graphs of both equations have the same slopes.
This tells you clearly that their graphs are parallel lines which never intersect.
Therefore, the 'system' of equations has no solution.

A park is in the shape of a rectangle 2 miles long and 1.5 miles wide. How much shorter if you walk diaganolly across the park rather than along two sides?

Answers

You can answer this by using Pythagoras theorem. Okay, let me draw this first.

2 miles
V

| | << 1.5 miles
|_______________________|

^ Assume this is the rectangle. The long side is 2 miles while the shorter side is 1.5 miles.

So, to get the shortest distance, let's cut out a triangle from the rectangle.

    /|
       / |

What we want to find is this one > / | << 2 miles
   / |
  /______|
   ^ 1.5 miles (I know the size is not logical,but imagine   it please)

So to get the diagonal length = $\sqrt{{a^(2) }+ b^(2)}$
= $\sqrt{{2^(2) }+ 1.5^(2)}$
= 2.5 miles

To calculate how much shorter = ( 2 miles + 1.5 miles) - 2.5 miles
= 3.5 miles - 2.5 miles
= 1.0 miles

72

Answers

25/60 = 30/x
x = 30/25 * 60
x = 1800/25
x = 72

So, option D is your answer.

Answers

Sports teams are switching to a variable-pricing strategy for tickets so that they can get higher profit on games with record attendance numbers. They feel the need to do so because the marginal cost, such as construction payment player's salaries, did not equal to the marginal revenue.
