Answer:
Step-by-step explanation:
Here is a tip: When you have something that looks like this - ( - , turn it into a plus sign. It looks kind of like a plus sign anyway. So if you have 53- (-32), turn it into 53 + 32. Does that make sense?
So 53 + 32 = 85.
Another tip to do it in your head, is to do 50 + 30 = 80, then do 3 + 2 = 5, and add them. It's easier than trying to juggle the odd numbers. :)
Steps to finding the line in the diagram with the format 'ax + by = c
1. Find the slope
- To find the slope, we need any two points on the line --> (0,4) and (3,0)
![Slope = \frac{y2-y1}{x2-x1} =\frac{4-0}{0-3} =-\frac{4}{3}](https://tex.z-dn.net/?f=Slope%20%3D%20%5Cfrac%7By2-y1%7D%7Bx2-x1%7D%20%3D%5Cfrac%7B4-0%7D%7B0-3%7D%20%3D-%5Cfrac%7B4%7D%7B3%7D)
2. Set up, with any one point on the line and the slope, in point-slope form
![(y-y0)=m(x-x0)\\(y-4)=-\frac{4}{3} (x-0)\\y-4 = -\frac{4}{3} x\\\frac{4}{3}x+y = 4](https://tex.z-dn.net/?f=%28y-y0%29%3Dm%28x-x0%29%5C%5C%28y-4%29%3D-%5Cfrac%7B4%7D%7B3%7D%20%28x-0%29%5C%5Cy-4%20%3D%20-%5Cfrac%7B4%7D%7B3%7D%20x%5C%5C%5Cfrac%7B4%7D%7B3%7Dx%2By%20%3D%204)
<u>Answer</u>: ![\frac{4}{3}x+y = 4](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B3%7Dx%2By%20%3D%204)
Hope that helps!
Ok so we know that y=1 so we can simply sub in the value of y into the equation :
y = -5x +3
1 = -5x +3
Move the -5x to the LHS ( Left-hand-side ) therefore it changes sign as well move 1 to the RHS ( Right-hand-side ) it also changes sign.
5x = 3 - 1
5x = 2
x = 2/5
x = 0.4
Hope this helps :).
