So far, so good. Now you cite the transitive property of congruence, saying objects congruent to congruent objects are congruent.

(IMO, another step might be needed. You have 2 ≅ 1 ≅ 7 ≅ 5, but you may have to show 1 ≅ 5 or 2 ≅ 7 before you can jump to 2 ≅ 5. The transitive property is usually written in terms of only one intermediate: a ≅ b ≅ c ⇒ a ≅ c.)

What are the coordinates of the turning point for the function f(x) = (x - 1)3 - 3? A. (-1, -3)

Naddik [55]

ANSWER

The turning point is

$(1,-3).$

EXPLANATION

The function given to us is

$f(x) = (x - 1) ^{3} - 3$

At turning point,
$f '(x) = 0$

So we need to differentiate the given function and equate it to zero.

We using the chain rule of differentiation, we obtain,
$f '(x) =3 (x - 1) ^{2}$

We equate this to zero to obtain,

$3 (x - 1) ^{2} = 0$

We divide through by 3.

$(x - 1) ^{2} = 0$

We solve for x to get,

$x - 1 = 0$

$x = 1$

We substitute this x-value in to the function to obtain the corresponding y-value of the turning point.

$f(1) = (1- 1) ^{3} - 3$

$f(1) = 0 - 3$

$f(1) = - 3$

Therefore the turning point is

$(1,-3)$

C is the correct answer.

Which expression is the same as 8x (4 x 2)?

ANTONII [103]

Answer:

64x

Step-by-step explanation:

because 4 * 2 is in parenthesis, that means you multiply 8x by them.

8x (4*2)

8x (8)

Write the point-slope form of the equation for a line that passes through (6,-1) with a slope of 2

Vika [28.1K]

Answer: y + 1 = 2(x-6)

Step-by-step explanation:

Point Slope Form is y-y₁=m(x-x₁), and all you have to so is substitute in the values that you were given. So, the slope is 2, so you substitute that value in for m. Then, you substitute 6 in for x₁ (because 6 is the x value of the coordinate you were given) and you substitute -1 for y₁ (and it becomes positive because two negatives make a positive)

Hope this was helpful! Please feel free to ask me any questions!
