Choose 3 values for x that would make this inequality true. 24&gt;2 (x+2)
kkurt [141]

Answer:

9, 2, 0

Step-by-step explanation:

Solving the inequality

24 > 2(x + 2) ← divide both sides by 2

12 > x + 2 ( subtract 2 from both sides )

10 > x

Thus we require values of x that are less than ( but not equal to ) 10

These are 9, 2 and 0

Can someone help we this and explain how to do it?
igomit [66]

Answer:

(0, 4) and (- 4, 0)

Step-by-step explanation:

We require the equation of the circle

The equation of a circle centred at the origin is

x² + y² = r² ( r is the radius )

The radius is the distance from the centre to a point on the circle

To calculate r use the distance formula

r = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (\sqrt{12}, - 2)

r = \sqrt{((\sqrt{12 )^2 - 0)+(-2-0)^2} }

  = \sqrt{12+4} = \sqrt{16} = 4, hence

x² + y² = 16 ← equation of circle

given y - x = 4 ⇒ y = x + 4

Substitute y = x + 4 into the equation of the circle

x² + (x + 4)² = 16 → distribute and simplify left side

x² + x² + 8x + 16 = 16

2x² + 8x + 16 = 16 ( subtract 16 from both sides )

2x² + 8x = 0

2x(x + 4) = 0

Equate each factor to zero and solve for x

2x = 0 ⇒ x = 0

x + 4 = 0 ⇒ x = - 4

Substitute these values into y = x + 4 for corresponding y- coordinates

x = 0 : y = 4 ⇒ (0, 4)

x = - 4 : y = - 4 + 4 = 0 ⇒ (- 4, 0)

The points of intersection are (0, 4) and (- 4, 0)

Which value is a solution to the inequality x – 4 &gt; 15.5? A) x = 21.4 B) x = 17.3 C) x = 15.5 D) x = 19.3
Lelu [443]

Answer:

A.) x = 21.4

Step-by-step explanation:

When solving the inequality, you can treat the sign like an equal sign. To isolate the "x" variable, you can add "4" to both sides. This eliminates the -4 from the right side.

You are left with the inequality:

x > 19.5

If "x" must be greater than 19.5, the only answer that satisfies this is A.) x = 21.4. All of the other answers are less than 19.5.
