For which of the following is x=-5 a solution? select all that apply. a) x+10=-5 b) -x^2+50=25 c) l2xl =10 d) x< 0 e) 2x< 10

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

case A) we have

Substitute the value of in the equation

------> the equation is not true

therefore

The value of is not a solution of the equation

case B) we have

Substitute the value of in the equation

------> the equation is true

therefore

The value of is a solution of the equation

case C) we have

Substitute the value of in the equation

-----> the equation is true

therefore

The value of is a solution of the equation

case D) we have

Substitute the value of in the inequality

--------> the inequality is true

therefore

The value of is a solution of the inequality

case E) we have

Substitute the value of in the inequality

--------> the inequality is true

therefore

The value of is a solution of the inequality

the answer is

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
