Answer:
= 17.25 pounds (Answer)
Step-by-step explanation:
Potatoes she bought = 23 pounds
Amount she gave outsiders= 10+15=25%
= 23×25/100= 23/4=5.75 pounds
Potatoes left with her= 23 — 5.75
= 17.25 pounds (Answer)
For this case we have that by definition, the equation of a line in the slope-intersection form is:
Where:
m: It is the slope
b: It is the cut point with the y axis
The slope is: 
Thus, the equation is of the form:
We substitute the given point and find "b":
Finally, the equation is:
Answer:
Answer:
Her initial position was:
-29ft
Where we use the minus sign because this is below the ocean's surface.
Now we also know that she keeps descending at a rate of -29ft per minute, then if she keeps descending for t minutes, her position will be:
P(x) = -29ft - 29ft/min*t
Now, we also know that she does not want to descend more than 81ft below the ocean's surface, then we have the inequality:
P(x) ≥ -81ft
-29ft - 29ft/min*t ≥ -81ft
Now let's isolate t in one side:
- 29ft/min*t ≥ -81ft + 29ft = -52 ft
- 29ft/min*t ≥-52 ft
t ≤ -52ft/(- 29ft/min) = 1.79 min
Then the maximum amount of time that she can keep descending is 1.79 minutes.
Answer:
x=7
Step-by-step explanation:
4(x-8)= -2(x-5)
4x+32= -2x+10
+2x +2x
6x-32=10
+32 +32
6x= 42
divide by 6 on both sides
x=7
