Answer:
y = 3/4x - 9/8
Then read explanation and see here with 2 coordinates would make
if 3/4 = -6 then 1 = -8
y = -6x + c
-6 / 3/4 + 9/8 / - 0.5 = -2.25
therefore c = -2.25
y = -6x - 2.25
y = -6x - 9/4 and again 9/4 can be found easily if round up fraction decimal to 225/100 and divide by 4
Step-by-step explanation:
C1) (0.5 , -0.75)
C2) ( 1. -3.75)
y = mx + c
-3.75 - - 0.75 / 1 - 0.5 = -3.75 + 0.75 / 0.5
= -3 / 0.5 = m
m = -6
y = -6x + c
then this works given just one coordinate to solve for 1 or 2 sets given points
y - y1 = mx+c
y - - 0.75 = 0.75 (x - x1)
y + 0.75 = 0.75 (x - 0.5)
y + 0.75 = 0.75x - 0.375
y = 0.75 - 0.75 = 0.75x( - 0.375 - 0.75)
y = 0.75x -1.125
y = 3/4x - 9/8 as common denominators of 1125/1000 is 9/8 as we divide by 125 into the fraction as we start at 250 and check its half just like when finding common denominators we 1/4 the lower number and see if we can find its half or its double etc with the other num er as first step for 3sf numbers.
1000 is possibly the answer to this equation
THe given equation is
![y=(1+4x)^{12}](https://tex.z-dn.net/?f=%20y%3D%281%2B4x%29%5E%7B12%7D%20)
Differentiating using chain rule
![dy/dx = 4*12(1+4x)^{11} = 48(1+4x)^{11}](https://tex.z-dn.net/?f=%20dy%2Fdx%20%3D%204%2A12%281%2B4x%29%5E%7B11%7D%20%3D%2048%281%2B4x%29%5E%7B11%7D%20)
At point (0,1), we will get
![dy/dx = 48(1+4(0))^{11} = 48](https://tex.z-dn.net/?f=%20dy%2Fdx%20%3D%2048%281%2B4%280%29%29%5E%7B11%7D%20%3D%2048%20)
Now we use point slope form, which is
![y-y_{1} = m (x-x_{1})](https://tex.z-dn.net/?f=%20y-y_%7B1%7D%20%3D%20m%20%28x-x_%7B1%7D%29%20)
Substituting the values of m, and x1,y1, we will get
![y-1=48(x-0)](https://tex.z-dn.net/?f=%20y-1%3D48%28x-0%29%20)
![y = 48x+1](https://tex.z-dn.net/?f=%20y%20%3D%2048x%2B1%20)
And that's the required answer .
I'm assuming that when you wrote "(7x/2-5x+3)+(2x/2+4x-6)," you actually meant "<span>(7x^2-5x+3)+(2x^2+4x-6). Correct me if I'm wrong here.
