Answer:

x² + 2x - 4

Step-by-step explanation:

The quadratic equation is ax² + bx + c =0

To solve this, you plug it into the quadratic formula (-b±√(b²-4ac))/(2a).

As it shows in the picture, -B = 2. There is no negative on the two in the equation because the quadratic formula makes any positive number negative in the first part.

The values of A and C are give in the parenthesis because they are being multiplied by -4.

The value for A = 1 and we can leave that as x² because 1 and x have the same value.

The value for C = -4 and that goes at the back of the equation, turning the plus sign after 2x negative.

When you put the equation together, you get x² + 2x - 4

Rectangle STUV is shown on a coordinate plane. Rectangle STUV with vertices S at negative 7 comma 6, T at negative 2 comma 6, U

rusak2 [61]

The coordinate of the point T after the given transformations is; T''(-2, -4)

<h3>How to carry out Translation Transformations?</h3>

We are given the coordinates of the rectangle STUV as;

S(-7, 6)

T(-2, 6)

U(-2, 1)

V(-7, 1)

Now, we are told that all these coordinates are translated using the transformation rule; (x, y) → (x − 2, y − 4)

Thus, the new coordinates using this transformation rule are;

S'(-9, 2)

T'(-4, 2)

U'(-4, -3)

V'(-9, -3)

Now, we are told that these new points are rotated 90° counterclockwise and as such the new coordinates formed will follow the pattern (x, y) → (-y, x).

Thus, our final coordinates are;

S''(-2, -9)

T''(-2, -4)

U''(3, -4)

V''(3, -9)

Thus, the coordinate of the point T after the given transformations is; T''(-2, -4)

On January 2, 2008, the American Idol website (www .americanidol) conducted an online poll that asked respondents which contesta

patriot [66]

Answer:

Online Poll

We can conclude that

c. most Americans prefer Clay Aiken out of those former contestants.

Step-by-step explanation:

Sample responses received from the poll = 941,434

Proportion of voters for Clay Aiken = 55%

Computed proportion of voters for the other 5 contestants = 45% (100% - 55%)

This gives an average of 7.5% (45%/5) for the other 5 contestants.

Therefore, the conclusion is that "most Americans prefer Clay Aiken out of those former contestants" in the American Idol contest.

All the cups are in there correct spot and the labels are fine also.

(then someone had to come in dis room with BLUE CAPS AND REPLACE ALL OTHER THE CORRECTLY ORDERER PEN CAPS WITH BLUE PEN CAPS AND SWITCH THE GOSH DARN LABELS. THANKS ALOT, TIM) anyways... i say that the minimum numbers of pens you can test is about 4. probably....

Which property states that the order of the addends does not affect the sum? commutative property of addition reflexive property

Nonamiya [84]

Answer:

Commutative property

Step-by-step explanation:

Commutative property states that no matter how the addens are placed, the result of the operation (sum) remains the same.
For <u>example</u>, given three numbers a, b and c, the result of $a+b+c=b+c+a=a+c+b$ .
Then, when you are solving a sum, the order of the elements does not matter. If we want to see this numerically, with an other example: $4+5=5+4=9$ .
