If you divide these numbers instead of trying to simplify it equals the decimal 0.8.
If you move the decimal point two places to the right it's 80%.
Answer:
7/2
Step-by-step explanation:
The slope of the line is given by
m = (y2-y1)/(x2-x1)
= (12-5)/(3-1)
= 7/2
Answer:
9x^3-17x^2-x+7
Step-by-step explanation:
Distribute the negative you'll get
(12x^3-8x^2)+(-3x^3-9x^2-x+7)
Combine like terms
12x^3-3x^3=9x^3 , -8x^2-9x^2=-17x^2 , -x , +7
Putting it all together:
9x^3-17x^2-x+7

7 days=7*24=168 hours
tablets=168*2/4
=84 tablets</span>
Ok, so a line with a perpendicular slope will have the opposite reciprocal slope, meaning that if the slope on y=-4x-7 is -4, the opposite reciprocal slope would be 1/4. so, if you plug the given point into your new line,
y=1/4x+b
1=1/4(4)+b
1=1+b
b=0
so, the final equation would be y=1/4x
(i think?)
