If a quadratic equation has solutions 
and 
, then we can write it as
So, in your case, we have (let me write 1.5 as 3/2 and -0.25 as -1/4)
If we don't want decimal coefficient, we can multiply the whole expression by 8:
Because it when graphed it passes vertical line test
15 has 1,3,5,15
18 has 1,2,3,6,9,18
12 has 1,2,3,4,6,12
Answer:
y = -2/5x + 9
Step-by-step explanation:
The slope will always be before the x. And intercept will always go after the slope. If your intercept is negative, remember to write it as x-9 rather than x+9.
And you'll always want to add the y = at the beginning
Well 3+4=7 so you have two different drawings which removes one marble if you draw and then you have 6. so first, you have 3/7 green and 4/7 to draw black marble. After then, you have either a 3/7 green and 3/7 black chance or a 2/7 green and 4/7 black chance to pull a color. you're more likely to pull a black marble first, then after getting a black marble you have a 50/50 chance of pulling either back or green.
