I'll do 14 and 18, and you can apply those techniques for the other problems!
For 14, we get 30*(1/10^8). This means that you move the decimal place in 00.0000030.0 seven places to the left, resulting in 0.00000300
For 18, we can use the associative property of multiplication to get
5*3.5*10^3*10^(-1)=17.5*10^2. We get 10^2 by adding 3 and -1 up. Since it's positive 2, we simply move the decimal 2 places to the right to get 1750
To find the y-intercept you first need to set everything equal to y and that will put everything in the y=mx+b line equation. Where m is the slope and b is the y intercept
x+3y = 14 subtract x over
3y = -x+14 divide by 3
y = -1/3x +14
So 14 is the y-intercept of the equation
The top equation, 3x+y-3=0.
When x is 0, y is 3 (also seen in graph).
When y is 0, x is 1.
Answer: x = -2
