Select all the correct answers.
Andrews [41]

Answer:

Option A, Option D and Option E are correct options.

Step-by-step explanation:

We need to find solutions of the inequality: 2x^2-1>6x

We will check the options and see, which options satisfy the inequality.

Option A

x=-4

Put x=-4

2x^2-1>6x\\2(-4)^2-1>6(-4)\\2(16)-1>-24\\32-1>-24\\31>-24\:\:True

So, x=-4 is the solution of inequality.

Option B

x=3

Put x=-3

2x^2-1>6x\\2(3)^2-1>6(3)\\2(9)-1>18\\18-1>18\\17>18\:\:False

So, x=3 is not the solution of inequality.

Option C

x=1

Put x=1

2x^2-1>6x\\2(1)^2-1>6(1)\\2(1)-1>6\\2-1>6\\1>6\:\:False

So, x=1 is not the solution of inequality.

Option D

x=5

Put x=5

2x^2-1>6x\\2(5)^2-1>6(5)\\2(25)-1>30\\50-1>30\\49>30\:\:True

So, x=5 is the solution of inequality.

Option E

x=-2

Put x=-2

2x^2-1>6x\\2(-2)^2-1>6(-2)\\2(4)-1>-12\\8-1>-12\\7>-12\:\:True

So, x=-2 is the solution of inequality.

So, Option A, Option D and Option E are correct options.

4x−2y=14 y=12x−1 solve by substitution
Tatiana [17]

Answer:

x= -3/5

Step-by-step explanation:

4x-2y=14

y=12x-1

4x-2(12x-1)=14

4x-24x+2=14

4x-24x=12

-20x=12

×= -12/20

x= -3/5

if you choose 1 scoop of ice cream from 12 flavors and any 1 topping from a choice of 8, how many different ice-cream sundaes ca
iVinArrow [24]

If you choose 1 scoop of ice cream from 12 flavors and any 1 topping from a choice of 8. Then the number of the different ways to make ice cream will be 96.

<h3>What are permutation and combination?</h3>

A permutation is an act of putting things or elements in the right sequence. Combinations are a method of picking things or pieces from a collection of objects or sets when the sequence of the objects is irrelevant.

If you choose 1 scoop of ice cream from 12 flavors and any 1 topping from a choice of 8.

Then the number of the different ways to make ice-cream sundaes will be

Let x be the number of the ways.

\rm x = \ ^{12}C_1 \times ^8C_1\\\\x = 12 \times 8\\\\x = 96

Then the number of the different ways to make ice cream will be 96.

More about the permutation and the combination link is given below.
