How would you describe slope mathematically?

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!

Answer:

4x(3y+1)

Step-by-step explanation:

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.

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]

Answer:

+ 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

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.

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

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

Answer:left is 7 right is 6

Step-by-step explanation:

left is 7 right is 6

Answer:

the right side is 6 and the left side is 7
