What value of m makes this equation true?

1 answer:

6 0

The correct answer is B) m=-8

First, add 9 on both sides of the equation. You should end up with 4m=-32.

Next, divide both sides of the equation by 4. You should end up with m=-8. (A negative divided by a positive equals a negative)

Hope this helps! Have a great day ;)

Can a triangle have more than one obtuse angle?

xxMikexx [17]

No, a triangle cannot have more than one obtuse angle. Obtuse angles are bigger than 90 degrees but smaller than 180 degrees. Pretend we had two obtuse angles both measuring 135 degrees and an acute angle measuring 23 degrees.

135 + 135 + 23 = 293
therefore, it wouldn't be a triangle anymore... a triangle only equals up to 180 degrees.

I hope that helps.

Paladinen [302]

Answer:

a. The domain of the function is -3 < x ≤ 5

b. The range of the function is -3 ≤ y < 3

c. The y-intercept is the point (0, 0)

d. The values of 'x' at which f(x) ≥ 0 are;

x = -3, x = 1, x = 5

e. The intervals over which f(x) is decreasing are;

-3 < x ≤ - 1, and 1 ≤ x ≤ 3,

f. The local minimums are;

(-1, -1), and (3, -3)

Step-by-step explanation:

a. The domain of a function is the set of the possible independent variable values

Therefore, the domain of the function is -3 < x ≤ 5

b. The range of a function is the set of the possible values of the dependent variable

Therefore, the range of the function is -3 ≤ y < 3

c. The y-intercept is the point (0, 0)

d. The values of 'x' for which f(x) ≥ 0 are;

x = -3, x = 1, x = 5

The range of values of 'x' where f(x) ≥ 0 are;

-3 < x ≤ - 1.5, 0 ≤ x ≤ 1.5, 4.5 ≤ x ≤ 5

e. f(x) is decreasing over the following intervals;

-3 < x ≤ - 1, and 1 ≤ x ≤ 3,

f. The local minimums are the points that are lowest compared to other nearby points

The local minimums are;

(-1, -1), and (3, -3).

Using proportions, it is found that the same job will take Mrs. Squirrel 6 hours.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The times are given as follows:

Mrs. Squirrel: x.

Mr. Turtle: 3 days.

Mr. Pigeon: 30 minutes = Half an hour = 1/48 day.

The ratios are as follows:

Turtle/Squirrel = Squirrel/Pigeon.

Hence:

$\frac{3}{x} = \frac{x}{\frac{1}{48}}$

$x^2 = \frac{3}{48}$

$x^2 = \frac{1}{16}$

$x = \sqrt{\frac{1}{16}}$

x = 1/4.

It takes 1/4 of a day for Mrs. Squirrel to do the job, hence 1/4 x 24 hours = 6 hours.
