<u>Answer:</u>

The line parallel to y – axis is x = 4. Thus option a is correct.

<u>Solution:</u>

Given, a set of options as linear equations.

We have to choose one which is parallel to the y – axis.

We know that, slope of y – axis is undefined.

As the required line is parallel to the y – axis, its slope should also be equal to slope of y – axis.

Now, let us check one by one option.

Now, a) x = 4

\rightarrow \text { slope }=\frac{-x \text { coeffiecient }}{y \text { coefficient }}=\frac{-1}{0}

= undefined

Here slope of this line is undefined. Which means it is parallel to y – axis.

So, we got our required answer.

Hence, the line parallel to y – axis is x = 4 i.e. option a is correct.

Plot 2 3/8 and 1 3/4 on the number line below
MariettaO [177]

Answer:

There is a picture below of the number line with the numbers, plotted.

Step-by-step explanation:

For the 2 3/8, you would simply go to 2 and count 3 to the right becuase there are 8 points for each whole number to the next. It's pretty hard to explain sorry. For 1 3/4, you would make the denominator 8, so multiply it by 2. When we do this, we multiply both the numerator and denominator. What is done to one must be done to the other. 3*2 to get 6. 4*2 to get 8. So, 3/4 becomes 6/8. Now, we can go to 1, and count 6 points to the right to get to 1 3/4.

The amounts of food waste generated in a region during two years were 37,500,000 tons and 30,400,000 tons. What was the total fo
galben [10]

You can change the form of the number to scientific notation before or after you do the addition. Here, we see the sum will be less than 100 million tons, so we can convert to scientific notation before we do the addition without requiring extra steps. The total waste is the sum of the amounts of waste in the two years.


... 3.75×10⁷ + 3.04×10⁷ = (3.75 +3.04)×10⁷ = 6.79×10⁷ . . . tons

Sarah paid $1,932 in tax on her new car which had a purchase price of $80,500 .
levacccp [35]

Answer:

so when looking at the tax minus the cost

100%/x%=80500/1932

(100/x)*x=(80500/1932)*x      

100=41.666666666667*x      

100/41.666666666667 or 6 infinite will get us

2.4=x

x=2.4

so times 2.4% with every cost to see it it matches the tax given!

A is incorrect

it equals 1632

B is not correct as it equals 2208

C is incorrect as it equals 1800 dollars in tax

<em>D is CORRECT as it has the same number in Tax</em>

<em>2040</em>

Could someone possibly help me with this question?
MrRa [10]

Answer:

See explanation

Step-by-step explanation:

      Statement                     Reason

1. the diagram shows segment AC with point B on this segment, then

   AB+BC=AC              <u>Segment addition postulate</u>

2. Given AB=2x,\ BC=6x+8,\ AC=32, then

   2x+6x+8=32              <u>Substitution property</u>

3. Simplify the equation as follows

   8x+8=32                      <u>Combine like terms</u>

4. Subtract 8 from both sides

   8x+8-8=32-8\\ \\8x=24          <u>Subtraction property of equality</u>

5. Divide by 8:

   x=3                                <u>Division property of equality</u>
