Answer:
4+3t
Step-by-step explanation:
4= The tree begins at 4 feet.
+3t =3 is the height in which it grows each year, t represents the number of years so we multiply that.
Answer:
1st one is 0.021
2nd one is 0.009
the last question is 0.015 tho
If PLAN A is cheaper than PLAN B then,
P (A) < P (B)
30+0.01t < 20+0.05t (subtract 0.05t from both sides)
29.95-0.04t < 19.95 (<span>subtract 29.95 from both sides)</span>
-0.04t < -10 (<span>divide both sides by -0.04)</span>
t > 250
<span>So plan A is cheaper than plan B when you send more than 250 texts.</span>
Hope it helps.
Answer:
The inverse is 5x+3
Step-by-step explanation:
y = (x-3) /5
Exchange x and y
x = (y-3)/5
Solve for y
Multiply each side by 5
5x =(y-3)/5 *5
5x = y-3
Add 3 to each side
5x+3 =y-3+3
5x+3 =y
The inverse is 5x+3
