Answer:
Step-by-step explanation:
y ∝ x^2
Introducing the proportionality constant, we have
y = kx^2
Given : y= 18 when x = 3
substitute the given values in order to get the constant
i.e 18 = k x 3^2
18 = 9k
k = 2
therefore the formula connecting x and y
⇒ y = 2x^2
To find y if x is 4, just substitute x = 4 into the formula connecting x and y
i.e y = 2 x 4^2
= 2 x 16
= 32
What I should do as you did to someone else is “Too bad XDDDD” but because I’m nice, I’m going to help you out, so convert the fraction into an improper fraction meaning 2+5/9 becomes 23/9, now times that by 3 and you will get 23/3, converting the rest of the answers into improper fractions will help you find the answer, which is 7+6/9 or choice 1
first set the first equation equal to x
subtract 2y from both sides
x=27-2y now plug this in to the other equation
2(27-2y)+3y=46 distribute
54-4y+3y=46 --> 54-y=46 now subtract 54 from both sides -y=-8 --> D)y=8
If you weren't asked to show work you could just plug the choices given into the equation
XY = −1−(−10) = 9
(line x = −5) = −5−(−9) = 4
Area = 1/2 * 9 * 4 = 18

Explanation:</h2>
Suppose you have the following problem:
<em>The population of Naguanagua in 2019 is estimated to be 20,000 people with an annual rate of increase of 4%. Which equation models the population of Naguanagua in t years?</em>
Let:
So the population of Naguanagua can be modeled by the following equation:
So the initial population is represented by which is the population at , in other words
