Which of the following are solutions to the equation below?

Mathematics
1 answer:
Luden [163]3 years ago
4 0

Answer:

c) -4/5

d) 4/5

Step-by-step explanation:

The given equation is 25x^2 -16 = 0

Adding 16 on both sides, we get

25x^2 = 16

Dividing both sides by 25, we get

x^2 = 16/25

Taking square root on both sides, we get

x = √(16/25)

x = ±4/5

Therefore, x = 4/5 and x = -4/5

Answers: C) and D)

Hope this will helpful to understand the concept.

Thank you.

The key on a stem-and-leaf plot shows that 1|9 represents 19. How would the number 402 be represented?
Andrew [12]
Hi again,

We need to find the key on a stem-and-leaf of the number 402 being represented.

<span>40|2 is your best answer

</span>Remember the last digit is the leaf and the rest of the numbers is the stem.

Hope this helped! :)

For how many (not necessarily positive) integer values of n is the value 4000x(0.4)^n an integer?
Delicious77 [7]

The number of integer values of n for which the value 4000 × (0.4)ⁿ is an integer is; 9

<h3>How to find the integer values in algebra?</h3>

We are given the expression;

4000 × (0.4)ⁿ

This can also be expressed as;

4000 × (²/₅)ⁿ which can further be expressed in exponent form as;

(2⁵ × 5³) × (²/₅)ⁿ = 2⁽⁵ ⁺ ⁿ⁾ × 5⁽³ ⁻ ⁿ⁾

Since this expression is an integer, we need:

1) 5 + n ≥ 0 for which n ≥ -5

2) 3 - n ≥ 0 for which n ≤ 3

Taking the intersection gives;

-5 ≤ n ≤ 3

Thus;

Number of Integer Values = 3 - (-5) + 1 = 9

8th grade linear functions, will give brainliest if the steps are listed and explained :)))
Rom4ik [11]

Get the slope of the line using the two known points:

slope = (7 3/4 - 6 1/4) / (1 1/4 - 3/4) = (1 2/4) / (2/4) = 3

Use the point-slope formula for a line to get the equation of the line. You can use any of the known points and the slope computed above. For example,

y - 6 1/4 = 3 (x - 3/4)   ⇒   y = 3x + 16/4 = 3x + 4

Then for some given value of x, the third point has y-coordinate 3x + 4.

"Which values" suggests there may be more to the question, namely some list of answer choices. If you have something like that, just check if the above condition is met.
