Two plumbers make house calls. One charges $105 for a visit plus $30 per hour
of work. The other charges $65 per visit plus $40 per hour of work. For how
many hours of work do the two plumbers charge the same?
Answer:
Step-by-step explanation:
plumber ones equation: y = 30x + 105
plumber two: y = 40x + 65
set the two equations equal to each other
30x + 105 = 40x + 65
solve for x
40 = 10x
4 = x
after 4 hours they will charge the same

someone pls help me with this :(
Answer:
y=Mx+c. you can just look at the gradient the m of the graphs. If the m is positive it means the graph is going up, if the m is negative, the line goes downwards. As for the value of m, it just means how steep the line is. Let's say you're going up a hill that has an m of 10, it would be wayy steeper and you'd be very tired than if the m were 1. So the 2x has the largest m in your question which is 2, so out of the four graphs, graph number 1 is the steepest and it's positive, which goes up.

No, there isn't a more efficient way to solve this system.
Yes, a more efficient way is to multiply the first equation by 4, add to eliminate y, then solve for x.
Yes, a more efficient way is to multiply the first equation by −4, add to eliminate y, then solve for x.

+ 6[tex]x^{2}[/tex] and -10[tex]y^{2}[/tex]
Step-by-step explanation:
3[tex]x^{2}[/tex] + 5[tex]y^{2}[/tex] {} + 3 {} + 4[tex]y^{2}[/tex] + 6 = 9[tex]x^{2}[/tex] - [tex]y^{2}[/tex]+ 9
3[tex]x^{2}[/tex] + 9[tex]y^{2}[/tex] {} + 9 {} = 9[tex]x^{2}[/tex] - [tex]y^{2}[/tex]+ 9
+ 6[tex]x^{2}[/tex] -10[tex]y^{2}[/tex]
3[tex]x^{2}[/tex] + 9[tex]y^{2}[/tex] + 6[tex]x^{2}[/tex] + 9 - 10[tex]y^{2}[/tex] = 9[tex]x^{2}[/tex] - [tex]y^{2}[/tex]+ 9
9[tex]x^{2}[/tex] - [tex]y^{2}[/tex]+ 9 = 9[tex]x^{2}[/tex] - [tex]y^{2}[/tex]+ 9
Given f(x) = 5 find if f(x) = - 3x - 4
Answer:
The answer is -3*5-4= -15-4=-19. So given f(x)=5 then x=-19.
Step-by-step explanation:
So basically when it says f(5) that means we need to plug in x=5 into the equation -3x-4. So lets solve, -3*5-4=-19. I hope this helps if you need any clarfication please comment. Please dont tell me you are cheating on a quiz/test/assestment. Cheating does not help you by the way!
Allison practices her violin for at least 12 hours per week. She practices for three fourths of an hour each session. If Allison has already practiced 3 hours this week, how many more sessions remain for her to meet or exceed her weekly practice goal?
Answer:
Sessions needed= 12
Step-by-step explanation:
Giving the following information:
Total hours= 12 hours
Practice= 3/4= 0.75 of an hour
Already practiced= 3 hours
First, we need to determine how many minutes does she practice each session:
Minutes per session= 0.75*60= 45 minutes
Now, we divide the total practice in minutes required for the minutes per session:
Sessions needed= (9*60) / 45
Sessions needed= 12
1+cos2a+sin2a/1-cos2a+sin2a=cota
Answer:
Proved
Step-by-step explanation:
Required
Show that:
[tex]\frac{1+cos2a+sin2a}{1-cos2a+sin2a}=cota[/tex]
[tex]cos2a = cos(a + a) = cos^2a - sin^2a[/tex]
So, we have:
[tex]\frac{1+cos^2a - sin^2a+sin2a}{1-(cos^2a - sin^2a)+sin2a}=cota[/tex]
[tex]\frac{1+cos^2a - sin^2a+sin2a}{1-cos^2a + sin^2a+sin2a}=cota[/tex]
[tex]1- cos^2a = sin^2a[/tex]
So, we have:
[tex]\frac{1+cos^2a - sin^2a+sin2a}{ sin^2a+ sin^2a+sin2a}=cota[/tex]
[tex]\frac{1+cos^2a - sin^2a+sin2a}{2sin^2a+sin2a}=cota[/tex]
Rearrange the numerator
[tex]\frac{1 - sin^2a+cos^2a+sin2a}{2sin^2a+sin2a}=cota[/tex]
[tex]1- sin^2a= cos^2a[/tex]
So, we have
[tex]\frac{cos^2a+cos^2a+sin2a}{2sin^2a+sin2a}=cota[/tex]
[tex]\frac{2cos^2a+sin2a}{2sin^2a+sin2a}=cota[/tex]
[tex]sin2a = 2sina\ cosa[/tex]
So, we have:
[tex]\frac{2cos^2a+2sinacosa}{2sin^2a+2sinacosa}=cota[/tex]
Factorize:
[tex]\frac{cosa(2cosa+2sina)}{sina(2sina+2cosa)}=cota[/tex]
Rewrite as:
[tex]\frac{cosa(2cosa+2sina)}{sina(2cosa+2sina)}=cota[/tex]
[tex]\frac{cosa}{sina} = cota[/tex]
[tex]cota = cota[/tex]
