Answer:

$\frac{1}{5}$ is the answer

Step-by-step explanation:

$h(x)=\frac{x+3}{5} \\$

Substituting the -2 in place x

Therefore , h(-2) :

$\frac{(-2)+3}{5} \\\frac{-2+3}{5}\\\frac{1}{5}$

Answer:

$\huge\underline\bold\blue{ƛƝƧƜЄƦ}$

$h(x) = \frac{ x + 3}{5}$

value of X is given to us -2

so put it in the equation.

$h(x) = \frac{ - 2 + 3}{5}$

$h(x) = \frac{1}{5}$

so the value of x is 1/5

Hope it helps

$Solution, \mathrm{Expand}\::\left(\sqrt{x}+\sqrt{y}\right)\left(\sqrt{x}-\sqrt{y}\right)\left(x+y\right)\left(x^2+y^2\right):\quad :x^4-:y^4$

$Steps:$

$\mathrm{Expand}\:\left(\sqrt{x}+\sqrt{y}\right)\left(\sqrt{x}-\sqrt{y}\right):\quad x-y, =\left(x-y\right)\left(x+y\right)\left(x^2+y^2\right)$

$\mathrm{Expand}\:\left(x-y\right)\left(x+y\right):\quad x^2-y^2, =:\left(x^2-y^2\right)\left(x^2+y^2\right)$

$\mathrm{Expand}\:\left(x^2-y^2\right)\left(x^2+y^2\right):\quad x^4-y^4, =:\left(x^4-y^4\right)$

$\mathrm{Expand}\::\left(x^4-y^4\right):\quad :x^4-:y^4, =:x^4-:y^4$

The correct answer is <u><em> $x^4-y^4$ </em></u>

Which one of these points lies on the given circle

Kruka [31]

Step-by-step explanation:

every point on the circle has the same distance from the center : r (radius).

we can see that radius right there on the x-axis : the distance of (3, 0) to (0, 0) is simply 3. that is our radius.

the distance formula is applied Pythagoras

distance² = (difference in x coordinates)² +

+ (difference in y coordinates)²

distance = sqrt( ... )

so,

(-2.5, - 2.5)

(-2.5 - 0)² + (-2.5 - 0)² = 6.25 + 6.25 = 12.5

that is not 3² = 9, so the point is NOT on the circle.

(1, 3)

(1 - 0)² + (3 - 0)² = 1 + 9 = 10

that is not 3² = 9, so the point is NOT on the circle.

(2, -sqrt(5))

(2 - 0)² + (-sqrt(5) - 0)² = 4 + 5 = 9

that IS 3² = 9, so, the point IS on the circle.

(-sqrt(3), -sqrt(7))

(-sqrt(3) - 0)² + (-sqrt(7) - 0)² = 3 + 7 = 10

that is not 3² = 9, so the point is NOT on the circle.

Aiden wrote a riddle: Five less than 1/5 times a number is same as the sum of the number and 1/3. Find the number

yanalaym [24]

To solve this riddle, first we have to put it into an algebraic expression, letting the variable n represent the unknown number we are looking for.

1/5n - 5 = n + 1/3

Next, we have to add 5 to both sides, to cancel out the -5 on the left side of the equation.

1/5n = n + 5 1/3

Then, we have to subtract n from both sides of the equation to cancel out the positive n on the right side of the equation.

-4/5n = 5 1/3

Finally, we have to divide both sides by -4/5 in order to get our variable n alone on the left side by canceling out its coefficient.

n = - 6 2/3

Therefore, the number in Aiden's riddle is -6 2/3 or -20/3.
