To determine if it is growth or decay, you just look if the y increases or decreases as x gets bigger. in this case as x gets bigger then y gets bigger, so it is growth.
to get y intercept, plug in 0 for x.and see what y equals. so:
y = 0.01(10)^0
anything raised to the zero power is 1. so:
y = 0.01 (1)
y = 0.01
that is y intercept.
Subtract 4 from both sides, y = 5

Answer: <u><em>The first number is 8</em></u>
Step-by-step explanation: Let the three No. s be x, y and z respectively
given = x+ y+ z= 72
y=7x
z=7x-18
∴As we know x+ y+ z=72
i.e. x+7x+7x-18=72
15x=72+18=90
15x=90
x=90/15
∴x=8
∴y=7x
7×8=56
∴z=7x-18
56-18=38
∴<u><em>The first no. is x=8</em></u>
<u><em>The second no. is y=7x = 56</em></u>
<u><em>The third no. is z=7x-18 = 38</em></u>
Step-by-step explanation:
|14- c| = 15
=> 14 - c = 15 or 14 - c = -15
=> c = -1 or c = 29.
