Answer:
r = 4
Step-by-step explanation:
If we clearly observe a point and the slope of the line are given.
Point=(5, -6) slope= -5
We know that the equation of the line having slope m and passing through point () is
Now the equation of the line is
Now given that (3,r) lies on this line
r = 4
Answer:
3:4
Step-by-step explanation:
divide into simplest form would be 3:4
The bar which Adelina should buy is super power brand because it cost less than feel great energy bar at $1.45 per bar
<h3>Unit price</h3>
Feel great energy bars = Total cost / number of bars
= $18 / 12
= $1.5 per bar
Super power brand = Total cost / number of bars
= $21.75 / 15
= $1.45 per bar
Therefore, the bar which Adelina should buy is super power brand because it cost less than feel great energy bar at $1.45 per bar

20+16+18+14+9+20+16=113
113÷7=16.14285714
after rounded the answer would be 16.
hope that's correct.
Answer:
c
Step-by-step explanation:
an exponential function of the form
y = a
to find a and b use ordered pairs from the table
using (0, 0.5 ) , then
0.5 = a [ = 1 ] , then
a = 0.5
so y = 0.5
using (1, 2 ) , then
2 = 0.5 = 0.5b ( divide both sides by 0.5 )
4 = b
then exponential function represented by the table is
y = 0.5
