Answer:

-3

Step-by-step explanation:

Solve for x in the inequality, to get x > -2 (see the image below if you want to know how to solve it). Then, we can substitute the numbers for x to see which ones DO NOT make the inequality true:

-1 > -2  This is <u>true</u>, because -1 <u>is greater</u> than -2

-3 > -2  This is <u>false</u>, because -3 <u>is </u><em><u>not</u></em><u> greater</u> than -2

7 > -2  This is <u>true</u>, because 7 <u>is greater</u> than -2

5 > -2  This is <u>true</u>, because 5 <u>is greater</u> than -2

So you can see that -3 is the number that DOES NOT make the inequality true. So therefore:

<u>Answer:</u> -3

Hope this helps! :)

Determine the discriminant for the quadratic equation 0=-2x2+3. Based on the discriminant value, how many real number solutions
Arlecino [84]

The discriminant of 0 = -2x^2 + 3 is 24 and it has 2 real solutions

<h3>How to interpret the discriminant?</h3>

The equation is given as:

0 = -2x^2 + 3

Rewrite as:

-2x^2 + 3 = 0

The discriminant of an equation is calculated using:

D = B^2 - 4AC

In this case, we have:

A = -2

B = 0

C = 3

So, we have:

D = (0)^2 - 4 * -2 * 3

Evaluate

D = 24

When the discriminant is 0 or more, then the equation has real roots

Hence, the discriminant of 0 = -2x^2 + 3 is 24 and it has 2 real solutions

A medium sized apple has 70 calories. This is 10 calories less than 1\4 of the calories in an old westie chocolate bar.How many
n200080 [17]

Answer:

The answer to your question is: 320

Step-by-step explanation:

Data

1/4 of the calories in a chocolate - 10 = calories in an apple

Equation

    Calories in a chocolate bar = 4(calories in apple + ten)

                                                                    = 4(70 + 10)

                                                                    = 4(80)

                                                                   = 320
