The negative outside a function with no other transformations reflects the graph of the function over the x-axis.

<h3>How to Interpret Graph Transformations?</h3>

When we talk about reflection in transformation, we know that ;

Reflection over x-axis is defined as a reflection or flip over the x-axis where the x-axis is the line of reflection used.

The formula for this is: (x, y) → (x, −y) . To reflect an equation over the x-axis, simply multiply the output variable by negative one: y = f(x) → y = −f(x)

Thus, we can conclude that the negative outside a function with no other transformations reflects the graph of the function over the x-axis.

Is 7/20 equivalent to 7 hundreds

scoundrel [369]

No. 7/20 is NOT equivalent to 7 hundreds or 7 hundredths.

7 hundreds is 700 in standard form.

7/20 will become a decimal number. It is equal to 0.35

0.35 is not equal to 700.

7 hundredths in decimal form is 0.07

0.35 is still not equal to 0.07.

in 2 h, kelly laid new floor tile over 1/5 of the room. when she was joined by annette, the rest of the work was completed in 3h

jeyben [28]

Answer: Annette will take 6 hours to do the entire job alone.

Step-by-step explanation:

Given: Time taken by Kelly to do $\dfrac{1}{5}$ of job = 2 hours

i.e. Time for complete job done alone by Kelly = $5\times2=10\ hours$

Rest of work = $1-\dfrac{1}{5}=\dfrac{4}{5}$ of the job

$\dfrac{4}{5}$ of the complete job done by both Kelly and Annette in 3 hours

Time would be taken by then to do entire job together = $3\times\dfrac{5}{4}=3.75\ hours$

Let t be the time taken by Annette to do job alone.

Then, as per situation

$\dfrac{1}{3.75}=\dfrac{1}{10}+\dfrac{1}{t}\\\\\Rightarrow\ \dfrac{1}{t}=\dfrac{1}{3.75}-\dfrac{1}{10}\\\\\Rightarrow\ \dfrac{1}{t}=\dfrac{4}{15}-\dfrac{1}{10}\\\\\Rightarrow\ \dfrac{1}{t}=\dfrac{1}{6}\\\\\Rightarrow\ t=6$

hence, Annette will take 6 hours to do the entire job alone.

What is the area of this triangle.

chubhunter [2.5K]

Answer:

13 square units

Step-by-step explanation:

You <em>could</em> calculate the length of each side using Pythagorean theorem, then use Heron's formula to find the area. But there's an easier way: find the area of the rectangle that contains the triangle, and subtract the areas of the smaller triangles in the corners.

The area of the rectangle is 4 × 7 = 28.

The area of the upper left triangle is ½(2)(4) = 4.

The area of the upper right triangle is ½(3)(5) = 7.5.

The area of the lower right triangle is ½(1)(7) = 3.5.

So the area of the triangle is:

28 − 4 − 7.5 − 3.5 = 13
