Answer:

6:2 12:4

These three ratio's are equivalent because if you reduce them to simplest form the answer will be 3:1. You multiply each number in the ratio by how many batches you want so for instance 3×2=6 and 1×2=2 so this gives you your first ratio for the 2 batches and 3×4=12 and 1×4=4 this gives you the ration for 4 batches.

Hope it helps :)

Could you please help me with questions 36 & 37?

Andrej [43]

We have to determine if the functions are linear or not.

We can do this by rearranging the equations in this form:

$y=mx+b$

where m and b are constants.

<em>NOTE: There are many ways to prove that a function is linear, but this is the easiest for this question. </em>

36.

$\begin{gathered} x+\frac{1}{y}=7 \\ \frac{1}{y}=-x+7 \end{gathered}$

As this function can not be written in the form y=mx+b, then it is not linear.

37.

$\begin{gathered} \frac{x}{2}=10+\frac{2y}{3} \\ \frac{x}{2}-10=\frac{2y}{3} \\ \frac{2y}{3}=\frac{1}{2}x-10 \\ y=\frac{3}{2}(\frac{1}{2}x-10) \\ y=\frac{3}{4}x-15 \end{gathered}$

This function is now in the form y=mx+b, where m=3/4 and b=-15. Then, this function is a linear function.

Answer:

36. Non-linear.

37. Linear.

Three consecutive odd integers add to −9. What are these integers?

Marat540 [252]

Let the number be x.

1st number = x
2nd number = x + 2
3rd number = x + 4

x + x + 2 + x + 4 = -9
3x + 6 = -9
3x = -15
x = -5

1st number = x = -5
2nd number = x + 2 = -3
3rd number = x + 4 = -1

Answer: The numbers are -1, -3, and -5

Decide if the function is an exponential function. If it is, state the initial value and the base. (5 points)

Irina18 [472]

Answer:

Exponential Function; base = 7; initial value = - 9.3

Step-by-step explanation:

Base is a number/value which has a variable exponent;

Initial value is the value of a function (i.e. y) when the independent variable, i.e. x, is equal to 0.
