Answer:
-1/3 is number one
Step-by-step explanation:
rearrange it so that instead of 19 - 9x = 22 it is -9x + 19 = 22 then subtract 19 from both sides of the equation then simplify.
Answer:
A
Step-by-step explanation:
solving the original equation
19 - 9x = 22 ( subtract 19 from both sides )
- 9x = 3 ( divide both sides by - 9 )
x = [tex]\frac{3}{-9}[/tex] = - [tex]\frac{1}{3}[/tex]
solving Maryanne's equation
- [tex]\frac{12}{5}[/tex] x + [tex]\frac{26}{5}[/tex] = 6 ( multiply through by 5 to clear the fractions )
- 12x + 26 = 30 ( subtract 26 from both sides )
- 12x = 4 ( divide both sides by - 12 )
x = [tex]\frac{4}{-12}[/tex] = - [tex]\frac{1}{3}[/tex]
solving Herb's equation
11 = 18x + 5 ( subtract 5 from both sides )
6 = 18x ( divide both sides by 18 )
[tex]\frac{6}{18}[/tex] = [tex]\frac{1}{3}[/tex] = x
Only Maryanne's equation has the same solution as the original equation

Answers
The inequality that can be used to determine whether the bag can be sold is; x + 7 >= 60
Representation using InequalitiesAccording to the question;
Any bag that is not within 7 grams of this mass cannot be sold.It then follows that since, the expected mass should be 60 grams.
The required inequality is; x + 7 >= 60

part one is -3 and 7
part two is -3
Answers
Answer:
Given equation:
[tex]\sqrt{30-2x} =x-3[/tex]
Square both sides:
[tex]\implies (\sqrt{30-2x})^2 =(x-3)^2[/tex]
[tex]\implies 30-2x =(x-3)^2[/tex]
Expand the right side:
[tex]\implies 30-2x =x^2-6x+9[/tex]
Add [tex]2x[/tex] to both sides:
[tex]\implies 30 =x^2-4x+9[/tex]
Subtract 30 from both sides:
[tex]\implies x^2-4x-21=0[/tex]
Factor:
[tex]\implies (x-7)(x+3)=0[/tex]
Therefore,
[tex]x-7=0 \implies x =7[/tex]
[tex]x+3=0 \implies x=-3[/tex]
Substitute both values of [tex]x[/tex] into the original equation to check:
[tex]x=7 :[/tex]
[tex]\implies\sqrt{30-2(7)} =7-3[/tex]
[tex]\implies 4=4[/tex]
correct!
[tex]x=-3[/tex]
[tex]\implies\sqrt{30-2(-3)} =-3-3[/tex]
[tex]\implies 6 \neq =-6[/tex]
incorrect!
Therefore, [tex]x=7[/tex] is the only correct solution, and [tex]x=-3[/tex] is the extraneous solution

Plug in coordinates to see if they match the answer.
It's easier in slope-intercept form, so lets change it first.
-2x+y=7
+2x +2x
y=2x+7
Now we can plug in the coordinates to see if they match.
Lets try A.
11=2(-2)+7
11=-4+7
11=3
A is incorrect.
Lets try B.
11=2(2)+7
11=4+7
11=11
B is a solution, therefore is on the graph.

What is the exact value of tan

Answers
Answer:
[tex]\displaystyle -\sqrt{3} - 2[/tex]
Explanation:
If you recall the unit circle [from the polar graph], you would have no trouble at all figuring this out, but sinse you have trouble, do not worry about it. So, here is what you should have realised:
[tex]\displaystyle \boxed{1\frac{1}{2}\pi} = \frac{18}{12}\pi[/tex]
If you did not notise, [tex]\displaystyle 1\frac{7}{12}\pi,[/tex]or [tex]\displaystyle \frac{19}{12}\pi,[/tex]is just [tex]\displaystyle \frac{\pi}{12}[/tex]more than [tex]\displaystyle 1\frac{1}{2}\pi,[/tex]which means the exact value will either be a radical, followed by an integer or just a radical. In this case, accourding to the unit circle, you will have a radical, followed by an integer, and that will be this:
[tex]\displaystyle \frac{sin\:1\frac{7}{12}\pi}{cos\: 1\frac{7}{12}\pi} = tan\:1\frac{7}{12}\pi \\ \\ \boxed{-\sqrt{3} - 2} = \frac{sin\:1\frac{7}{12}\pi}{cos\: 1\frac{7}{12}\pi}[/tex]
It is all about memorisation of the unit circle, which I know is difficult, but you will get used to it soon.
*Now, if you had to find [tex]\displaystyle cos\:\frac{7}{12}\pi,[/tex]then the exact value would be the OPPOCITE of the exact value of [tex]\displaystyle sin\:\frac{7}{12}\pi,[/tex]which is [tex]\displaystyle -\frac{\sqrt{2} + \sqrt{6}}{4},[/tex]because you would be crossing into the second quadrant where the x-coordinates are negative, accourding to both the cartesian and polar graphs. In addition, sinse you ALREADY have both values for sine and cosine [accourding to your PREVIOUS QUESTION ASKED], all you need to do is divide both values in the order given above to arrive at the exact value for [tex]\displaystyle tan\:1\frac{7}{12}\pi.[/tex]
