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
Haha number one is 3 and two is 2
<span>3x=7y+16
15y=7y + 16
15y - 7y = 16
8y = 16
y = 8/16
y = 2
hope this helps you !!! =')</span>
1.d. 2.c 3.b 4.d Justt got a 100% its right!!!
