Find one counter example to show that the conjecture is false. angle 1 and angle 2 are​ supplementary, so one of the angles is a
Mrac [35]

Answer:

B. m ∠ 1 = 90° and m ∠ 2 = 90°

Step-by-step explanation:

For most situations, the conjecture would probably be true, but there is one exception that makes this statement false.

When two right angles are supplementary, none of them is acute.

For an angle to be acute it needs to be lesser than 90°, and for a pair of angles to be supplementary they should add up to exactly 180°.

With a pair of right angles (90° each), their sum adds up to 180° but neither of them are acute.

Therefore, the answer is B. m ∠ 1 = 90° and m ∠ 2 = 90°

R(x)=x^3+5x^2-2x-24 Plot the zero(s) of the function.
nevsk [136]

:) Brainliest pls?

Answer:

The zeros are {2, -3, -4} which need to be plotted on the x-axis.

Step-by-step explanation:

I'll find the zeros, aka x-intercepts, and you could probably graph them.

To find the zeros, let's factor this polynomial:

r(x) = (x - 2)(x^2+7x+12)

r(x) = (x - 2)(x + 3)(x + 4)

The zeros are {2, -3, -4} which need to be plotted on the x-axis.

Error Analysis: Describe the error in the way the difference of the two polynomials is set up and/or
maria [59]

Answer:

  The distributive property is not properly applied to the second polynomial.

Step-by-step explanation:

For whatever reason, it is a common mistake to say that ...

  -(a +b +c) = -a +b +c . . . . WRONG!

Rather, it should be ...

  -(a +b +c) = -a -b -c . . . . CORRECT

Write an equation of the parabola that has the same shape as the graph of ​f(x)​, but with the point ​(​,​) as the vertex.
erik [133]

Answer:

y=3(x-9)^2+4

Step-by-step explanation:

To move a parabola horizontally to the right, subtract 9.

To move it upward 4 units, you simply have to add 4.

These do not change the characteristics of the shape. I suggest looking at a set of rules that affect how the parabola moves horizontally and vertically.
