is slope-intercept form, which is a way of writing an equation for a line.
In this equation, 
represents the slope and 
represents the y-intercept.
and 
are the coordinates of a point on the resulting line.
Here are some examples:
Answer:
3) 8
4) 5.25 cups
Step-by-step explanation:
3) cross multiply:
36 × 10 = 360
45 × x = 45x
equate them both:
360 = 45x
divide both sides by 45
360 ÷ 45 = 8
x = 8
4) 8 people : 3 cups of flour
14 people : how many cups?
14 ÷ 8 = 1.75
to get from 8 people to 14 people we multiply by 1.75, so do the same thing to the 3 cups:
3 × 1.75 = 5.25 cups
The slope-intercept form:
m - slope
b - y-intercept → (0, b)
We have the point (0, 5). Therefore b = 5.
We have: y = mx + 5
Other point (3, 2). Substitute the coordinates of the point to the equation of the line:
<em>subtract 5 from both sides</em>
<em>divide both sides by 3</em>
<h3>Answer: f(x) = -1x + 5 = -x + 5</h3>
Gee wiz man I don't know. that is a really big number. have you tried google? :/
32 grams = water mass + sugar mass . 100% syrup=75% water+ 25%sugar
original water content= 32*75/100=24 grams
original sugar content= 32*25/100= 8grams
total mass at 10% syrup:
8grams/total mass=10%=0.1
total mass=8/0.1=80grams
total mass of water=80grams- 8grams of sugar content= 72 grams
total mass of water added=72grams- 24grams original water content= 48grams.
answer: 48grams
