Answer:

∠DSE = 24°

Step-by-step explanation:

The ∠ASE = 168° is the sum of the angles

∠ASB + ∠BSC + ∠CSD + ∠DSE, thus

13° + 85° + 46° +∠DSE = 168°, that is

144° + ∠DSE = 168° ( subtract 144° from both sides )

∠DSE = 24°

Does the construction demonstrate how to copy a segment correctly by hand? Option A: Yes; the compass was kept at the same width

The correct answer is A.

To create the line linger than AB, a straightedge was used.

To measure AB, a protractor was used.

This is how CD was created.

Best of Luck!

Answer:

$\dfrac{9}{2}$

Step-by-step explanation:

You can do this using the quadratic equation:

$x =\dfrac{-b\pm\sqrt{b^{2}-4ac}}{2a}$

Let's first setup our expression:

4x² + 12x = 135

the quadratic formula is:

ax² + bx + c = 0

4x² + 12x - 135 = 0

Then:

a = 4

b = 12

c = -135

Now we plug in our coefficients and solve:

$x =\dfrac{-12\pm\sqrt{12^{2}-4(4)(-135)}}{2(4)}$

We solve for both to determine the positive one:

$x =\dfrac{-12+ \sqrt{12^{2}-4(4)(-135)}}{2(4)}$ $x =\dfrac{-12- \sqrt{12^{2}-4(4)(-135)}}{2(4)}$

$x =\dfrac{-12+ \sqrt{144+2160}}{8}$ $x =\dfrac{-12- \sqrt{144+2160}}{8}$

$x =\dfrac{-12+ \sqrt{2304}}{8}$ $x =\dfrac{-12- \sqrt{2304}}{8}$

$x =\dfrac{-12+ 48}{8}$ $x =\dfrac{-12- 48}{8}$

$x =\dfrac{36}{8} = \dfrac{9}{2}$ $x =\dfrac{-60}{8} = \dfrac{-15}{2}$

So if you are looking for a positive solution, just take the positive one as x.

Write 0.8 as a fraction.

Scrat [10]

0.8=0.8/1=8/10=4/5
not one of them
but,

2/9=0.2222222222
4/9=0.444444444444
7/9=0.7777777777
8/9=0.88888888888

I think you meant 0.8 repeating so

answer is D

Which set of ordered pairs below is a function?

Paha777 [63]

The answer is A.

Ordered pairs that equate to a function would not have two separate points with the same x-value. In other words, every x-value must be associated with only one y-value.
