I Have Tried It For Multiple Times But It Still Doesnt Work TvT! Please Help Me Eight This Question

Answers

Answer 1

Answer:

  a) x = -2

  b) 8 integer values

Step-by-step explanation:

Matthew's solution is correct as far as it goes. However, he failed to take into account the possibility of negative square roots.

His solution might rightly look like ...

  3 < 3x² ≤ 75

  1 < x² ≤ 25 . . . . . divide by 3

  1 < ±x ≤ 5 . . . . . . take the square root

Separating the results:

  1 < x ≤ 5

  -1 > x ≥ -5 . . . . . . multiply by -1

a)

The value x=-2 shows Matthew's solution is incorrect:

  3 < 3(-2)² ≤ 25   ⇒   3 < 12 ≤ 25 . . . true

__

b)

x can have the integer values {-5, -4, -3, -2, 2, 3, 4, 5}, a total of 8 values.

__

In the attached, the white space (and dashed line) are the solution set. The shaded areas (and solid line) are excluded from the solution set.

_____

Additional comment

It can be helpful to remember that ...

  [tex]\sqrt{x^2}=|\,x|\ne x[/tex]

That is, values of x may be negative, but the positive square root will only show you a positive value.

Terry walks 1/4 mile each morning
and 2/4 mile each afternoon. How far does Terry walk in 3 days? Draw bar diagrams and write equations to solve
the problem

Answers

Answer:

1 1/2

Step-by-step explanation:

To solve this problem, we need to find how many miles Terry walks in one day. Then, we can multiply by 3 to find how far she walks in three days.

One day |

We need to add how much she walks in both the morning and afternoon. 1/4 + 2/4 = 3/4 miles.

Three days |

Now that we know how much Terry walks in one day, we need to find how much she walks in three days. Multiple by 3 to solve this.

3/4 * 3 = 6/4 = 3/2

You can write 3/2 as an improper fraction: 1 1/2.

Johnny bought an oil painting originally priced at $80 but on sale for 50% off. After 10% sales tax, what was the total cost?

Answers

Answer:

Step-by-step explanation:

A sales tax is never applied until money actually changes hands.

So you need to start by taking 50% off.

50% 0f 80 dollars = 50/100 * 80 = 4000/100 = 40

So the cost of the painting = 80 - 40 = 40

Now apply the sales tax

10% of 40 dollars = 10/100 * 40 = 400/100 = 4

The total cost = 40 + 4 = 44 dollars

solve the following equation 6/8 + 1 equals 26 - 2 x ​

Answers

Answer:

x = 97/8​

Step-by-step explanation:

6/8 + 1 = 26 - 2x

6/8 + 8/8 = 26 - 2x

14/8 = 26 - 2x

14/8 - 26 = -2x

14/8 - 208/8 = -2x

-194/8 = -2x

194/16 = x

x = 97/8​

as the first 2 lines show us : there is a linear relationship between minutes and words.

1 minute correlates to 250 words.

2 minutes correlate to 500 = 2×250 words.

so, we see, every minute represents 250 words.

Why is 45 minutes
equal to 3/4 of an hour?

Answers

1 hour = 60 minutes

45 min = (45 min)/(60 min) = 45/60 = 3/4 of an hour.

To go from 45/60 to 3/4, I divided both top and bottom by the GCF 15.

Answer:

45 minutes equal to 3/4 of an hour because, if you convert the one hour into minutes (60 minutes) it is divisible by 15 four times.
