# Which of the following is x=-5 a solution a) x+10=-5 b)-x^2 +50=25 c) [2x]=10 d) x is less than 10 e)

###### Question:

## Answers

It might be letter c

-x?+50=250

Step-by-step explanation:

-x=-5

if we put the value of x in the equation

b. -x^2 + 50 = 25

c. |2x| = 10

d. x < 0

e. 2x < 10

Step-by-step explanation:

x = -5

-(-5)² + 50

-25 + 50 = 25

|2(-5)| = |-10| = 10

-5 < 0

2(-5) = -10 < 10

C and D

Step-by-step explanation:

Plug X in and see which equations/expressions are true

I think the answer is 3 but I’m not sure.

Hope this helps!

Let's check each of the cases to determine the solution of the problem

case A) we have

[tex]x+10=-5[/tex]

Substitute the value of [tex]x=-5[/tex] in the equation

[tex](-5)+10=-5[/tex]

[tex]5=-5[/tex] ------> the equation is not true

therefore

The value of [tex]x=-5[/tex] is not a solution of the equation

case B) we have

[tex]-x^{2} +50=25[/tex]

Substitute the value of [tex]x=-5[/tex] in the equation

[tex]-(-5)^{2} +50=25[/tex]

[tex]-(25) +50=25[/tex]

[tex]25=25[/tex] ------> the equation is true

therefore

The value of [tex]x=-5[/tex] is a solution of the equation [tex]-x^{2} +50=25[/tex]

case C) we have

[tex]\left|2x\right|=10[/tex]

Substitute the value of [tex]x=-5[/tex] in the equation

[tex]\left|2(-5)\right|=10[/tex]

[tex]\left|-10\right|=10[/tex]

[tex]10=10[/tex] -----> the equation is true

therefore

The value of [tex]x=-5[/tex] is a solution of the equation [tex]\left|2x\right|=10[/tex]

case D) we have

[tex]x < 0[/tex]

Substitute the value of [tex]x=-5[/tex] in the inequality

[tex]-5 < 0[/tex] --------> the inequality is true

therefore

The value of [tex]x=-5[/tex] is a solution of the inequality [tex]x < 0[/tex]

case E) we have

[tex]2x[/tex]

Substitute the value of [tex]x=-5[/tex] in the inequality

[tex]2*(-5) < 10[/tex]

[tex]-10 < 10[/tex] --------> the inequality is true

therefore

The value of [tex]x=-5[/tex] is a solution of the inequality [tex]2x[/tex]

the answer is

[tex]-x^{2} +50=25[/tex]

[tex]\left|2x\right|=10[/tex]

[tex]x < 0[/tex]

[tex]2x[/tex]

Hello there!

Since we're looking for an equation to have a solution of x = -5, let's solve them from answer choice "A.)" to answer choice "D.)"

x + 10 = -5

x = -15

A.) is not correct.

Let's try B.)

-x^2 + 50 = 25

x^2 = -25

x = -5

Answer choice B.) is correct.

Let's continue looking for answer choices, just in case.

Let's look at answer choice C.)

2x = 10

x = 5

This answer is not correct.

Let's look at answer choice D.)

x < 0

This means x is less than 0, or a negative number.

This answer is not specifically correct.

Let's look at answer choice E.)

2x < 10

x < 5

This is less than 5, but does not specifically answer our chances.

Your answer is B.)

I hope this helps!

If 5x = -25 what does x equal? if 4x = -20 what does x equal? if 3x = -15 what does x equal? if 2x = -10 what does x equal?

The correct answer is C and D

Uhhh where’s the answer choices?
