Which situation is best modeled by the inequality v ≥ 18?

you must be older than 18 years old to vote.

you must be at least 18 years old to vote.

you can vote before you turn 18 years old.

you cannot vote when you are 18 years old.

You must be at least years old to vote

Step-by-step explanation:

we have

The solution of this inequality is the interval-----> [18, ∞)

All real numbers greater than or equal

Analyze each statement

case A)  You must be older than years old to vote

In this case the inequality that represent the statement is

-----> is not the solution

case B)  You must be at least years old to vote

In this case the inequality that represent the statement is

-----> is the solution

case C)  You can vote before you turn years old

In this case the inequality that represent the statement is

-----> is not the solution

case D)  You cannot vote when you are years old

In this case you cannot vote when

so

you can vote for

or -------> is not the solution

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

regards,  

mrb

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!
