Answer:
x=-3/2y+2
y= y=−3x+6
Step-by-step explanation:
solve for x.
2x+3y=4
Add -3y to both sides.
2x+3y+−3y=4+−3y
2x=−3y+4
Divide both sides by 2.
2x/2= -3+4/2
x= -3/2 y+2
solve for y.
y+3x=6
Add -3x to both sides.
3x+y+−3x=6+−3x
y=−3x+6

Vertical Angles: Find the Supplementary Angles (photo provided)
Answer:
105°
Step-by-step explanation:
The given angles are vertical and congruent , then
8x - 21 = 6x + 3 ( subtract 6x from both sides )
2x - 21 = 3 ( add 21 to both sides )
2x = 24 ( divide both sides by 2 )
x = 12
Then
6x + 3 = 6(12) + 3 = 72 + 3 = 75°
Supplementary angles sum to 180° , thus
supplementary angle = 180° - 75° = 105°

FIND THE VALUE OF X
Answer:
80
Step-by-step explanation:
Answer:
11/2
Step-by-step explanation:
Sum of angles in a triangle = 180°
84 + x +59 +x + 31 =180°
84+54+31+x+x = 180°
169 + 2x = 180°
2x = 180 - 169
2x = 11
x = 11/2

What are the answers to the last two questions?
Answer:
[tex](-1)(x+3)(x-2)[/tex]
Step-by-step explanation:
Factoring
We are given a trinomial:
[tex]-x^2-x+6[/tex]
The following steps are done to factor the trinomial.
1. Confirm there are no common factors: No common factors (given)
2. Factor out -1:
Multiply all the terms by -1 and take -1 out:
[tex]\boxed{(-1)(x^2+x-6)}[/tex]
3. Factor
[tex]x^2+x-6 = (x+p)(x+q)[/tex]
We have to find two numbers p and q whose product is -6 and the sum is 1. Those numbers are 3 and -2 (in any order):
Factoring:
[tex]x^2+x-6 = (x+3)(x-2)[/tex]
The final factoring is:
[tex]\boxed{(-1)(x+3)(x-2)}[/tex]

Complete the square for the following equation x^2-18x
Answer:
Multiple answers would work
Step-by-step explanation:
From the subtraction sign before the 18x, we can infer that one of the equations has a negative number. So, know we have this:
(x-?) (x+?)
There are multiple answers this could be,
(x-18) (x)
(x-20) (x+2)
You get where I am going...
If you went with the first on (x-18) (x), then you wouldn't have to add anything.
(x-20) (x+2) = x^2 - 18X - 40.
To be honest this one stumped me. Some just have multiple answers. My guess is that you have to fill out the boxes so maybe the first answer wouldn't work.
Sorry I couldn't give a concise answer. Though their probably is one obivious answer that I am missing.

Step-by-step explanation:
Subtract 3 from both sides of the equation /8+3=19
x/8+3=19
/8+3−3=19−3

PLS SOMEBODY ANSWER IM DESPERATE I NEED AN ANSWER OMGGGG I WILL GIVE BRAINLIEST JUST ANSWERR!!! maria earns $4.76 an hour at the local supermarket. each week, 25% of her total pay is deducted for taxes. in addition, she pays $25 a week, after taxes, in union dues. if she wants her takehome pay to be at least $100 a week, how many hours must she work? show work pls :)
Step-by-step explanation:
Let x be the number of hours Maria work per week.
We have 0.75 * $4.76x - $25 >= $100.
Therefore 0.75 * $4.76x >= $125,
$4.76x >= $166.66
x >= 35.014
Hence Maria have to work at least 36 hours per week.

Where q≠0
Step-by-step explanation:
We need to find each of the following as a rational number in the form of p/q
(a) (3/7)² (b) (7/9)³ (c) (-2/3)⁴
Solution,
(a) (3/7)²
[tex](\dfrac{3}{7})^2=\dfrac{9}{49}[/tex]
(b) (7/9)³
[tex](\dfrac{7}{9})^3=\dfrac{7\times 7\times 7}{9\times 9\times 9}\\\\=\dfrac{343}{729}[/tex]
(c) (-2/3)⁴
[tex](\dfrac{-2}{3})^4=\dfrac{-2\times -2\times -2\times -2}{3\times 3\times 3\times 3}\\\\=\dfrac{16}{81}[/tex]
Hence, this is the required solution.

You have 200 bottles of Medicine. 99% contain Medicine A; the rest, Medicine B. How many bottles of Medicine A do you need to use/empty to get Medicine A to 98%?
Answer:
I need to empty 2 bottles to get Medicine A to 98% of the total bottles
Step-by-step explanation:
The first step is to find out what 99% of 200 is. This will give us how many bottles of "Medicine A" are present.
99% of 200 is 198. This means that there are 198 bottles of Medicine A present.
The next step is to find out what 98% of 200 is. This will give us the number of bottles of "Medicine A " that will be left remaining.
98% of 200 is 196. There neede to be 196 bottles left after I have taken out and emptied a few bottles of Medicine A.
The last step is to subtract 196 from 198 bottles, to get the number of bottles that I need to empty.
This will be 198 - 196 = 2 bottles
I need to empty 2 bottles to get Medicine A to 98% of the total bottles

Which of the following is a counterexample for the hypothesis "All parallelograms are rectangles"?
Answer:
The answer would be B
Step-by-step explanation:
A non-square rhombus. A non-square rhombus (also known as a rhombus) is different from a square with respect to its internal angles. Unlike a square, a non-square rhombus does not have all its internal angles equal to 90°. The number of lines of symmetry in a non-square rhombus is 2, whereas, a square has 4 lines of symmetry.
The required counterexample is rhombus for the given hypothesis "All parallelograms are rectangles" which is the correct answer would be option (B).
What is the hypothesis?In statistics, hypothesis testing is the process by which an analyst tests an assumption about a population's parameter. Using sample data, hypothesis testing is performed to examine the plausibility of a theory.
A rhombus that isn't square. In terms of internal angles, a non-square rhombus (also known as a rhombus) differs from a square. A non-square rhombus, unlike a square, does not have all of its internal angles equal to 90°. A non-square rhombus has two lines of symmetry, whereas a square has four lines of symmetry.

2y + 3y = 4 - 6 - 13
Answer:
y=-3
Step-by-step explanation:
2y+3y=4−6−13
2y+3y=4+−6+−13
(2y+3y)=(4+−6+−13)
5y=−15
5y=−15
y= −3
Answer:
y = -10
Step-by-step explanation:
You add 2y and 3y, you'd get 5y from it. You do 4-6-13 which is -15.
So 5y = -15.
You subtract 5 from the y side and add 5 to the -15.
So basically:
5y = -15
-5 & +5
y = -10
