Answer:
r ≥ -1. it is A because r is greater than or equal to -1.
I am sorry <u>if</u> I got it wrong.
Step-by-step explanation:
3r+2(12r+7) ≤ 5r-8
27r+14 ≤ 5r-8
I subtract 27r and 5r.
22r+14 ≤ -8
I subtract 14 and -8.
22r ≤ -22
Divide 22 on both side.
r ≥ -1
Answer:
Step-by-step explanation:
25, because yes and because 20% is not an accurate number for 5 snakes to have
X = time, minutes
y = length, inches
When x = 32 min, y = 11.2 in
When x = 32+18 = 50, y = 10.75 in
Assume that a linear relatioship exists between x and y.
In table form, the given data is
x, min: 32 50
y, in: 11.2 10.75
The slope is
m = (10.75 - 11.2)/(50 - 32) = -0.025
In point-slope form, the required equation is
When x = 3 hours = 180 minutes, obtain
y - 10.75 = -0.025*(180 - 50) = -3.25
y = -3.25 + 10.75 = 7.5 in
Answer: 7.5 inches
