U find the slope of the two points, and that is the rate of change. the slope equation is y2-y1/x2-x1 ,, so for example, if you have the points (3,1) and (4,6) the equation you would do is 6-1/4-3 , which is equal to 5/1 (aka 5) , therefore the rate of change (and slope) is 5
Answer:
53.12
Step-by-step explanation:
You can do it 2 ways
1st way
83 multiplied by .33
83 is the amount and .33 is the percent
Now you have the mark downed price, so you subtract that from the original of 83
2nd way
subtract 33 from 100 because the price is 33% off
now multiply 83 by 0.64 because the .64 represents 64%
X=alice
b=barry
c=charlene
x=15 more than b
x=15+b
c=2 times of b
c=2b
all together
x+c+b
15+b+2b+b
15+4b
they have 15+4b or 15+4 times of barry
if we want in terms of x
x=15+b
x-15=b
15+4(b)
15+4(x-15)
15+4x-60
4x-45
they have 4x-45 together
2 x = 72
4 n = 7.5
6 no solution (the variable cancelled itself out)
8 no solution
10 x = 43
12 y=-5.83-x
14 <em>(P-2l)/2 = w</em>
16 Your team's score was 85 (because you scored 13 more points than the other team and 72 + 13 = 85).
18 The other scientist had the greater temperature (950 C > 1725 F), since 950 C = 1742 F
