1. Sometimes, 2. Never, 3. Always, 4. NeverStep-by-step explanation:
1. Vertical angles are complementary
Sometimes (if measure45°)2. Vertical angles are adjacent
Never3. The complement of an acute angle is an acute angle
Always. Both of them < 90°4. The supplement of an obtuse angle is an obtuse angle
Never. Obtuse angle > 90°, supplement is (180° - obtuse), which is <90° so is acutesimplify

k-2-6+5k
Answer:
-5v+3v = -2v
k-2-6+5k = 6k - 8
Step-by-step explanation:
For -5v+3v
-5 + 3 = -2
V is left so it's -2v
For k-2-6+5k
k + 5k - 2 - 6
6k - 2 - 6
6k - 8
1) -5v + 3v
= -2v
2) k - 2 - 6 + 5k
First take all like terms (everything with the same letters):
k + 5k = 6k
6k - 2 - 6
-2 - 6
= -8
6k - 8

For questions 3 & 4, name the applicable polynomial identity and use the identity to multiply each expression.
3. (2 + 8)(2 − 8)
4. ( + 33)2
Answer:
The quadratic x2 − 5x + 6 factors as (x − 2)(x − 3). Hence the equation x2 − 5x + 6 = 0
has solutions x = 2 and x = 3.
Similarly we can factor the cubic x3 − 6x2 + 11x − 6 as (x − 1)(x − 2)(x − 3), which enables us to show that the solutions of x3 − 6x2 + 11x − 6 = 0 are x = 1, x = 2 or x = 3. In this module we will see how to arrive at this factorisation.
Polynomials in many respects behave like whole numbers or the integers. We can add, subtract and multiply two or more polynomials together to obtain another polynomial. Just as we can divide one whole number by another, producing a quotient and remainder, we can divide one polynomial by another and obtain a quotient and remainder, which are also polynomials.
A quadratic equation of the form ax2 + bx + c has either 0, 1 or 2 solutions, depending on whether the discriminant is negative, zero or positive. The number of solutions of the this equation assisted us in drawing the graph of the quadratic function y = ax2 + bx + c. Similarly, information about the roots of a polynomial equation enables us to give a rough sketch of the corresponding polynomial function.
As well as being intrinsically interesting objects, polynomials have important applications in the real world. One such application to error-correcting codes is discussed in the Appendix to this module.

pleasee help mee ;-; i can't stand algebra, determine how many terms the geometric series has, and then find the sum of the series
-12 -4 - 4/3 - . . . - 4/243
Answer:
The series has 7 terms
[tex]\displaystyle S_7=\frac{4372}{243}[/tex]
Step-by-step explanation:
Geometric Series
In the geometric series, each term is found by multiplying (or dividing) the previous term by a fixed number, called the common ratio.
We are given the series:
-12, -4, -4/3, ..., -4/243
We can find the common ratio by dividing one term by the previous term:
[tex]\displaystyle r=\frac{-4}{-12}[/tex]
Simplifying:
[tex]\displaystyle r=\frac{1}{3}[/tex]
Sum of terms: Given a geometric series with first term a1 and common ratio r, the sum of n terms is:
[tex]\displaystyle S_n=a_1\frac{1-r^n}{1-r}[/tex]
We need to find how many terms the series has. Using the explicit formula of a geometric series:
[tex]a_n=a_1\cdot r^{n-1}[/tex]
The last term is an=-4/243 and the first term is a1=-12. Solving for n:
[tex]\displaystyle n= \frac{\log(a_n/a_1)}{\log r}+1[/tex]
[tex]\displaystyle \frac{\log(-4/243/-12)}{\log 1/3}+1[/tex]
[tex]\displaystyle \frac{\log(1/729)}{\log 1/3}+1[/tex]
n=7
The series has 7 terms
Thus, the sum of the 7 terms of the series is:
[tex]\displaystyle S_7=-12\frac{1-(1/3)^7}{1-(1/3)}[/tex]
[tex]\mathbf{\displaystyle S_7=\frac{4372}{243}}[/tex]

Simplify the Variable part of the SQRT
Rules for simplifing variables which may be raised to a power:
(1) variables with no exponent stay inside the radical
(2) variables raised to power 1 or (-1) stay inside the radical
(3) variables raised to an even exponent: Half the exponent taken out, nothing remains inside the radical. examples:
(3.1) sqrt(x8)=x4
(3.2) sqrt(x-6)=x-3
(4) variables raised to an odd exponent which is >2 or <(-2) , examples:
(4.1) sqrt(x5)=x2•sqrt(x)
(4.2) sqrt(x-7)=x-3•sqrt(x-1)
Applying these rules to our case we find out that
SQRT(x16y36) = x8y18

Answer:

Step-by-step explanation:
Answer:
If I'm understanding the question right it's -.05
Step-by-step explanation:
(2x - 3) = 2
There is no more simplifying to be done in the parentheses.
2x - 3 = 2
Subtract 3 on each side to get the x value by itself.
2x = -1
Divide each side by 2 so the x is by itself.
x = -.05

A fair coin is flipped 5 times
What is the probability that no two consecutive flips have the same result?
Express ur answer as a common fraction
HELP ME!!
Answer:
2/5
Step-by-step explanation:
The answer is common sense.
The probability that no two consecutive flips have the same result is [tex]\frac{1}{16}[/tex].
If a coin is flipped then there are two possible outcomes Head(H) and Tail (T).
So each flip can have 2 possible outcomes. It means 5 flips have [tex]2^5=32[/tex] possible outcomes.
Among these 32 outcomes only 2 outcomes : HTHTH and THTHT have "no two consecutive flips have the same result".
So the probability that no two consecutive flips have the same result is = [tex]\frac{2}{32} =\frac{1}{16}[/tex].

Answer:
80°
Step-by-step explanation:
alternate angles are equal
angles in a straight line add upto 180°
therefore angle ABC =80°
But it is alternate to the one at x.
Answer:
x = 80°
Step-by-step explanation:
∠CBD = ∠ABF
= 100°
(Vertically opposite angles are equal and AD and EH are parallel with CG cutting across both lines)
∠x = 180°-100°
= 80°
(∠ABF and ∠x are consecutive interior angles as they are within two parallel lines so they add up to 180°)
use (x+a)(x+b)=x2+(a+b)x+ab find 101*102
Answer:
[tex]101 * 102 = 10302[/tex]
Step-by-step explanation:
Given
[tex](x + a)(x + b) = x^2 + (a + b)x + ab[/tex]
Required
Find 101 * 102
[tex]101 * 102 =[/tex]
Express as a sum of 100
[tex](100 + 1) * (100 + 2)[/tex]
Compare this to [tex](x + a)(x + b)[/tex]
We have that:
[tex]x = 100[/tex]
[tex]a = 1[/tex]
[tex]b = 2[/tex]
Recall that:
[tex](x + a)(x + b) = x^2 + (a + b)x + ab[/tex]
Substitute 100 for x, 1 for a and 2 for b
[tex](100 + 1) * (100 + 2) = 100^2 + (1 + 2) * 100 + 1 * 2[/tex]
[tex](100 + 1) * (100 + 2) = 100^2 + 3 * 100 + 2[/tex]
[tex](100 + 1) * (100 + 2) = 10000 + 300 + 2[/tex]
[tex](100 + 1) * (100 + 2) = 10302[/tex]
Hence:
[tex]101 * 102 = 10302[/tex]
