For which of the following inequalities is x greater than or equal to 4 a solution?

1 answer:

4 0

Either a or b. Depends on what X equals. For example, question a.- X+3, it has to be at least 1. Answer b- 3X, has to be a little over 2. So I guess the most correct answer has to be A.

An airplane flies into the wind for 5 hours, traveling 900 miles. The airplane then

Musya8 [376]

Answer:

22.5 miles per hour

Step-by-step explanation:

Given system of equations

5(s-w)=900

4(s+w)=900

Set equations equal to each other

5(s-w)=4(s+w)

5s-5w=4s+4w

s-5w=4w

s=9w

Solve for w using the substitution s=9w

4(s+w)=900

4(9w+w)=900

4(10w)=900

40w=900

w=22.5

Therefore, the speed of the wind is 22.5 miles per hour

kumpel [21]

Answer:

-1.28 AND 2.61

Step-by-step explanation:

$10= -4x+3x^2\\ 3x^2 -4x - 10 = 0\\\\$

use quadratic formula

x = $\frac{-b+\sqrt{b^{2} -4ac} }{2a}$ x = $\frac{-b-\sqrt{b^{2} -4ac} }{2a}$

Solution/X-Intercepts: -1.28 AND 2.61
