Answer:
A = 10,482
B = 7,590
Explanation:
If A is the number of times show A was performed, and B is the number of times show B was performed:
We know that A + B = 18072
And we know A = B + 2892
So we’ll substitute the expression (B + 2892) for A in the first equation and solve for a numerical value of B:
A + B = 18072
B + 2892 + B = 18072
2B + 2892 = 18072
2B = 15,180
B = 7,590
A = B + 2892
A = 7590 + 2892
A = 10,482
Check the math
A + B = 18072
10,482 + 7,590 = 18,072

Answer:
Slope form: y=1x-5
Solution:
Y-y1=m(x-x1) plug in coordinates into formula.
Step-by-step explanation:
I think substitution would be the easiest since you already have one of the variables solved for.
![y=-x^2+4x+5\\y=x+1\\x+1=-x^2+4x+5\\x^2-3x-4=0\\(x-4)(x+1)=0\\x-4=0\\x=4\\x+1=0\\x=-1](https://tex.z-dn.net/?f=y%3D-x%5E2%2B4x%2B5%5C%5Cy%3Dx%2B1%5C%5Cx%2B1%3D-x%5E2%2B4x%2B5%5C%5Cx%5E2-3x-4%3D0%5C%5C%28x-4%29%28x%2B1%29%3D0%5C%5Cx-4%3D0%5C%5Cx%3D4%5C%5Cx%2B1%3D0%5C%5Cx%3D-1)
(You can just set the equations equal to each other since they both equal y).
Now, to get the points, plug in x = 4 and x = -1 into one of the equations (I'm going to plug them into y = x+1 because that one is much simpler)
![y(4)=4+1\\y(4)=5\\y(-1)=-1+1\\y(-1)=0](https://tex.z-dn.net/?f=y%284%29%3D4%2B1%5C%5Cy%284%29%3D5%5C%5Cy%28-1%29%3D-1%2B1%5C%5Cy%28-1%29%3D0)
So, your final points are:
(4,5) and (-1,0)
You must know that % is a number out of 100.
Therefore given 91/100 trusted DNA surveying, we know as a percentage this is 91% from the equation below:
(91/100)*100=91
We can conclude that 1%=1 person.
Although the difference is only 1 (91-90=1), the actual proportion of people who trust DNA testing is larger than the 90% by 1%.
If the temperature falls from 72°F to 36°F in four minutes, it means it fell 72-36 = 36°F in four minutes.
To find out what's the value of the temperature fall in one minute we just have to divide 36 by 4:
36 / 4 = 9
Answer: The temperature fell 9°F per minute.
