(07.03 LC)
Grace [21]

Answer:

B

Step-by-step explanation:

THis is a single equation with a single variable [y].

We can separate the variable in one side and the numbers to another and solve for y. Shown below:

3y + 4 = -2

3y = -2 - 4

3y = -6

y = -6/3

y = -2

THus, this equation has only 1 solution. B is correct

What is the coefficient of y in expansion of (y+4)^4 ?
lidiya [134]
256.

The coefficient of just the y term would be 256 because the entire expanded equation looks like this:

y^4+16y^3+96y^2+256y+256

A necklace found at a pawn shop is 192 grams and has a volume of 19.5 cubic centimetres. What metal is the necklace made of?
valentinak56 [21]

Answer:

Bronze

Step-by-step explanation:

Let's calculate the density of this necklace.

Density is mass divided by volume: m / v. Here, we know the mass is m = 192 grams, and we also know the volume is v = 19.5 cubic centimetres. Plug these into the equation:

d = m / v

d = 192 / 19.5 = 9.85 g / cm³

Looking at the chart, the closest density to this is that of bronze, which is 9.87. So, the necklace is likely made of bronze.

Consider the function represented by 9x + 3y= 12 with x as the independent variable. How can this function be written
elixir [45]

For this one, you don't need to actually do any work.

Function notation is the f(x) or f(t) notation, but with function notation, the variable in the parentheses must match the variable on the right side of the equation.

f(a) = 2b+3 won't do any calculation because of the mismatched a and b.

Which answer is the only one with good function notation?
