Simplify the expression:
8(2x - 3) - 6x = 8×2x - 8×3 - 6x = 16x - 24 - 6x = 10x - 24
for x=3
put value of "x" to the expression:
<u>10×3 - 24 = 30 - 24 = 6</u>
Answer:
m = 10
Step-by-step explanation:
Given w is inversely proportional to m then the equation relating them is
w =
← k is the constant of variation
To find k use the condition w = 8, m = 25 , then
8 =
( multiply both sides by 25 )
200 = k
w =
← equation of variation
When w = 20 , then
20 =
( multiply both sides by m )
20m = 200 ( divide both sides by 20 )
m = 10
The correct one is bottom left
Answer:
4
Step-by-step explanation:
To find the rate of change for the increase (warm up), use the coordinate pair of any two points on the line that slopes upwards in the graph.
Let's use the following:
At 5 mins (x), heart beats (y) is 80 => (5, 80)
At 10 mins (x), heart beats (y) is 100 => (10, 100)
Rate of change = 


Rate of change is 4.
