How to solve inequalities ?

When solving an inequality:

you can add the same quantity to each side you can subtract the same quantity from each side you can multiply or divide each side by the same positive quantity If you multiply or divide each side by a negative quantity, the inequality symbol must be reversed.

a.

Given : √(3-√15)²-√(3+√15)²

   √(3-√15)²-√(3+√15)² = (3-√15)-(3+√15)

   √(3-√15)²-√(3+√15)² = 0 -2√15

   √(3-√15)²-√(3+√15)² = -2.√15

b .  

Given : 3√c² if c≥0

     3√c² if c≥0

    c ≥ 0

c.

Given: √(x²+1)²=5

     √(x²+1)²=5

      on Squaring both sides , we get

      (x²+1) = 25

      x²  = 24

      x = ±2√6

d.

Given : -5√y² if y>0

      -5√y² if y>0

       y < 0 [since , -5 < 0]

e.  

Given : 0.5√16a² if a<0

     0.5√16a² if a<0

      a > 0

What is the area of the right angle

Answers

Answer:

3.84 inches squared

Step-by-step explanation:

The area of a triangle is given by the formula:

Area = 1/2 * base * height

In this problem, our side lengths are:

Base = 2.4 inches

Height = 3.2 inches

So, our area can be found:

Area = 1/2 * 2.4 * 3.2 = 3.84 inches squared

What solution equals x^4=81

Answers

Answer:

Step-by-step explanation:

3^4=81

3 to the square root of 4 is 81

3*3*3*3=81

Answer:

Since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

The inverse (opposite operation) of "to the fourth power" is "to the fourth root".

(x^4) ^ 1/4 = 81 ^ 1/4

81 = 3^4

so, (3^4) ^ 1/4 = 3 ^ 1 = 3

by hand: (3^4) 1/4 = 3 ^

(4 × 1/4) = 3^1 = 3

(when you take a power to a power, multiply the exponents.)

Or, do it by calculator. One way of finding the fourth the fourth root is to use ^ (1/4).

What is the slope of a line parallel to the line whose equation is 9x+3y=-27
Fully simplify your answer.

Answers

Answer:

One example would be y = -3x

Step-by-step explanation:

We can more easily find a line parallel to the given equation if it is put in slope intercept form.

3y = -27 - 9x

y = -3x - 9

So the slope is -3. You can choose any line also with a slope of -3.

Question 5 (1 point)
If y varies jointly as x and z and y = 18 when x = 2 and z = 3, find y when x is 5 and z is 6.

Answers

Answer:

y = 90

Step-by-step explanation:

If y varies jointly as x and z, then;

y = kxz

If y = 18 when x = 2 and z = 3

18 = k(2)(3)

18 = 6k

k = 18/6

k = 3

To get y when x = 5 and z = 6

y = kxz

y = 3(5)(6)

y = 15*6

y = 90

Hence the value of y is 90
