Answer:

Step-by-step explanation:

what we need to do is distribute the - sign in the middle of the parentheses into (7x^2 - 7 -8x^3)[/tex], this is very important to ensure we have the correct answer. by distributing we get the following equation:

now we combine like terms to get our answer
stays as it is, since there is nothing to combine it with
7x³ + 8x³ = 15x³
3x² - 7x² = -4x²
7 stays the same because like
, there is nothing else to combine it with
we have the following new equation:

Answer: 2,749.50
Step-by-step explanation:
56,715*10.70% = 6068.505
8818 - 6068.505 = 2,749.50
Answer:
Hi , the answer is 280-140/ 4-2 = 140/2
y = 2/140 x
b . 70 beats each minute
Step-by-step explanation:
we will take a 2 point from the graph
(280,4) , (y1,x1) and (140, 2) , (y2,x2) each point represent a (y,x) point
m = y1-y2 / x1-x2 = 280-140 / 4-2 = 140 /2
now , y/x = 140/2 ... by B. Multiplication we will get y = 2/140 x
b .
from the graph we see that every minute the curve increase 70 beats
Thanks
