Which graphs represents the compound inequality x<5/4 or x> 5/2?

Answers

Answer 1

Answer:

Answer: B

Step-by-step explanation:

Looking at the inequalities, both are ≤ and ≥. That means the x is not only greater or less than, but they are also equal to the number. With this fact, we can eliminate D since D has open circles.

Orr problem has 2 separate inequalities. Both are doing in different directions, hence the ≤ and ≥. This makes B automatically our answer. We can check by graphing each of the inequalities on the number line.

x≤5/4

We know that 5/4=1.25. We start at 1.25. Then the inequality tells less than or equal to. Since it is less than, we would travel to the left, where the numbers get smaller and smaller.

x≤5/2

5/2=2.5 We start at 2.5. The inequality tells us greater than or equal to. This means we have to travel to the right, where the number gets larger and larger than 2.5.

What 2 numbers multiply to be -14 and add to be -3

Answers

xy = -14
x + y = -3

$xy = -14$
$(xy)/(x) = (-14)/(x)$
$y = (-14)/(x)$

$x + y = -3$
$x + (-14)/(x) = -3$
$(x^(2))/(x) + (-14)/(x) = -3$
$(x^(2) - 14)/(x) = -3$
$x^(2) - 14 = -3x$
$x^(2) + 3x - 14 = 0$
$x = \frac{-(3) \± \sqrt{(3)^(2) - 4(1)(-14)}}{2(1)}$
$x = (-3 \± √(9 + 56))/(2)$
$x = (-3 \± √(65))/(2)$
$x = (-3 \± 8.06)/(2)$
$x = -1.5 \± 4.03$
$x = -1.5 + 4.03$ $or$ $x = -1.5 - 4.03$
$x = 2.53$ $or$ $x = -5.53$

  x + y = -3
2.53 + y = -3
- 2.53 - 2.53
  y = -5.53
  (x, y) = (2.53, -5.53)

x + y = -3
  -5.53 + y = -3
+ 5.53   + 5.53
  y = 2.53
  (x, y) = (-5.53, 2.53)

The two numbers that multiply to -14 and add up to -3 are -5.53 and 2.53.

Step-by-step explanation

A penny is thrown straight down froma height of 200 feet. At the same time, a
paintbrush is dropped from a height of
100 feet. The polynomials represent the
heights (in feet) of the objects after
t seconds.
-16t²- 40t + 200
-16t² + 100
a. Write a polynomial that represents the distance between the penny and the
paintbrush after 7 seconds.
b. Interpret the coefficients of the polynomial in part (a).

Solve 5(g-2)+g = 6(g-4)

Answers

$5(g-2)+g = 6(g-4)$
$5g-10+g = 6g-24$
$6g-10 = 6g-24$
$6g-6g=-24+10$
$0=-14$
$0 \neq -14$

5(g-2)+g = 6(g-4)
5g-10+g = 6g-24
6g-10=6g-24

What is the solution set of {x | x 2} ∪ {x | x ≥ 2}

Answers

the solution to this sets union is:

{x | x = 2} ∪ {x | x ≥ 2}
= { x | x >= 2 }

that is the total solution of the union., the second set is a superset of the first, so the total solution is the second set itself.
