Which statement best illustrates using the vertical line test to determine if the graph below is a function of x ?

2 answers:

4 0

If something is a function, every x-value, only has one (1) y-value. If the line x = 0 intersects the graph in two points, there are to values for y (instead of one). Therefore the graph is not a function of x.

Your answer is A.

Answer:

Step-by-step explanation:

A function can only have one output value "y" for each input "x", so if a vertical line in an xy plane (therefor the line test) that you can imagine, or you can see by using a ruler intersects more than one point on the same line, you have more than one value for x, and that is not a function.

as you see in option A, the line x=0 intersects the graph at two points.

Ruth has a beaker containing a solution of 800 mL of acid and 200 mL of water. She thinks the solution is a little strong, so sh

NISA [10]

Answer:

350 mL of water

Step-by-step explanation:

Well she starts with 200mL of water and there is 800 mL of acid of water.

She drains 100 mL of acid and adds 100 mL of water so there is 300 mL of water.

And she stirs meaning the compounds have mixed.

Then she drains 100 mL and she they are mixed she drains half of acid and half of water so she has 250 mL of water.

The she adds 100 mL of water so now there’s 350 mL of water left.

The large rectangle below represents one whole. What percent is represented by the shaded area? (URGENT)

nikitadnepr [17]

Answer:

40%

Step-by-step explanation:

The whole rectangle is split into 5 parts. Two out of 5 parts are shaded.

Set up a fraction:

$\frac{\text{Shaded}}{\text{Whole}}=\frac{2}{5}$

Convert into a decimal:

$\frac{2}{5}= 0.4$

Multiply the decimal by 100 to get the percent:

$0.4*100=40$

So, forty percent of the rectangle is shaded.

Hope this helps.

Perform the calculation then

Andru [333]

Answer:

416 (3 s.f.)

Step-by-step explanation:

To multiply decimals, begin by multiplying the numbers as if there is no decimal:

$\large\begin{array}{cccccc}&& 1 & 2 & 8 & 5\\\times && & 3 &2 & 4\\\cline{1-6} && 5 & 1 & 4 & 0\\&2&5&7&0&0\\3&8&5&5&0&0\\\cline{1-6}4&1&6&3&4&0\\\cline{1-6}^1&^1&^1&&\phantom{^{\frac{1}{2}}}&\end{array}$

Count the number of digits after the decimal point in each factor:

128.5 → 1 digit after the decimal point.
3.24 → 2 digits after the decimal point.

Therefore, there is a total of 3 digits after the decimal points.

Put the same number of digits after the decimal point in the product.

Therefore, the solution is to the multiplication is:

416.340

The factor with the fewest signification figures is 3.24.

This number has 3 significant figures.

Therefore, the solution to 3 significant figures is:

416 (3 s.f.)
