12d+34> 100
will brainliest

d > 5.5

d > 11/2

Step-by-step explanation:

To solve the inequality (find all possible values of "d" for the statement to be true), isolate "d". This means to separate it from all of the other numbers. Do this by performing reverse operations in reverse BEDMAS (brackets, exponents, division, multiplication, addition, subtraction) order.

12d + 34 > 100          

12d + 34 - 34 > 100 - 34       Subtract 34 from both sides. It's the reverse operation for adding 34.

12d > 100 - 34       34 - 34 on the left side cancels out

12d > 66       Simplify 100-34

12d/12 > 66/12   Divide both sides by 12 to isolate "d"

d > 66/12    Reduce to lowest terms. 66 and 12 are both divisible by 6.

d > 11/2        Answer in lowest terms

d > 5.5         Answer as a decimal

Therefore, for 12d + 34 > 100  to be true, "d" must be greater than 5.5 or 11/2.

part a- option 1 is exponential and increases 130% per year. option 2 increases $300 per year and it's linear.

part b- f(n)=1000+300n option 2

f(n)=1000(1.30)^n option 1

part c- f(20)=1000+300(20)

f(20)=1000+6000

f(20)=7,000 after 20 years for option 1

f(20)=1000(1.30)^20

f(20)=1000(190.04)

f(20)=190,040 after 20 years for option 2

we can see that there would be a significant difference in belinda's investment if she uses option 2 over option 1. there is a huge difference of 190,040 - 7,000 = 183,040 dollars.
