Let f(x) be y.

y = x³ + 3

Switch x and y:

x = y³ + 3

Now you need to isolate y and you would get inverse function.

x - 3 = y³

∛(x-3) = y

Final answer: f ⁻¹(x) = ∛(x-3)

Hope this helps.

Answer:

7. ○ ∆ACB ≅ ∆DFE

6. ○ $\displaystyle 43°$

5. ○ $\displaystyle ∠M ≅ ∠S$

4. ○ $\displaystyle octagon$

3. ○ $\displaystyle squares$

2. ○ $\displaystyle rhombus$

1. ○ $\displaystyle equilateral\:triangle$

Step-by-step explanation:

7. Everything is in correspondence with each other, so just follow the pattern in the order the they were originally.

6. All angles correspond with each other, so just follow the pattern.

5. All segments and angles correspond with each other, so just follow their patterns.

4. An octagon has eight sides, a triangle has three sides, a hexagon has six sides, and a pentagon has five sides. With this being stated, you have your answer.

3. In a previous lesson, we confirmed that all squares are rectangles because it is a quadrilateral with four right angles.

2. This is obviously a rhombus because it is a quadrilateral with four congruent angles and sides.

1. An EQUILATERAL TRIANGLE is a regular polygon because they have three congruent angles and sides.

I'm assuming your allowed to use a calculator for this? That's what I would do.
$\sqrt{108} = 10.39$
To go about the fraction, take the whole number and times it by the denominator, then add in the numerator to create a new fraction(a whole one not mixed). Then simply divide the numerator by the denominator.
$9 \times 20 = 180$
$180 + 13 = 193$
193 is the new numerator and the new whole fraction is this and dividing it out gives you,
$\frac{193}{20} = 9.65$
For the third one, just input it into a calculator,
$2\pi + 3.4 = 9.68$

What number must you add to complete the square x^2+4x=15

Andrew [12]

Since we want it in the form: (x - a)², let's first expand (x - a)² and then equate for the coefficients.

(x - a)² = x² - 2ax + a²
x² + 4x - 15 = x² - 2ax + a²

Now, let's focus on the middle term.
4x = -2ax
4 = -2a
a = -2

Thus, we know that a = -2
Then, we can say (x + 2)² = x² + 4x - 15
x² + 4x + 4 = x² + 4x - 15
Thus, 19 units are needed in order to complete the square to produce:
(x + 2)²
