Answer:

6/x

Step-by-step explanation:

(3x^2)(2x^-3)

Multiply the coefficients

3*2 = 6

Add the exponents

x^2 * x^-3 = x^(2-3) = x^-1

We know that a^-b = 1/ a^b

6 x^-1 = 6 * 1/x^1 = 6/x

Answer:

Perpendicular (A)

Step-by-step explanation:

First find the gradient of the first line:

Change in y/ Change in x =  -7-(-2)/ -9-(-12) = -5/3

Now find the gradient of the second line:

9-6/1-6 = -3/-5 = 3/5

When we multiply the gradient of two perpendicular lines we will get:

m1 x m2 = -1

If we multiply 3/5 and -5/3 we will get -1

Therefore it is perpendicular!

Answer:

98 degrees

Step-by-step explanation:

The measure of angle 1 is  92°

The correct option is B.

When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.

Given:

A transversal intersects 2 lines to form 8 angles.

Clockwise from the top left, the angles are blank, 88 degrees, blank, (7 x + 4) degrees;

blank, blank, (7 x minus 2) degrees, blank.

Now, the property of the supplementary angles:

m∠1 + m∠2 = 180°

m∠1 = 180 - 88

m∠1 = 92°

Therefore, the angle measure of angle 1 is 92°.

Step-by-step explanation: L = W + 4

LW = 60

---

LW = 60

(W + 4)W = 60

W^2 + 4W + (-60) = 0

---

above is in quadratic equation form: ax^2 + bx + c = 0

---

use the quadratic formula to solve for two solutions:

x = ( -b +- sqrt( bb - 4ac ) ) / 2a

---

the two solutions are:

W = 6

W = -10

the negative solution doesn't make sense for length, so use the positive solution.

The number of different possible party outcomes does Noah have with all of the given options is 18 ways.

Permutations are different ways of arranging objects in a definite order. It can also be expressed as the rearrangement of items in a linear order of an already ordered set. The symbol nPr is used to denote the number of permutations of n distinct objects, taken r at a time.

Given that,

Number of themes = 3

Number of party places = 2

Number of days = 3

Number of outcomes = 3×2×3

= 18 ways

Therefore, the number of different possible party outcomes does Noah have with all of the given options is 18 ways.

Answer:

See Explanation

Step-by-step explanation:

From your question, what you need is the explanation;

Given that [tex](x - 1 - \sqrt{2})(x - 1 + \sqrt{2})[/tex]  is a factor of p(x)

Required: Simplify

[tex](x - 1 - \sqrt{2})(x - 1 + \sqrt{2})[/tex]

Group the expression above

[tex]((x - 1) - \sqrt{2})((x - 1) + \sqrt{2})[/tex] -------- Expression 1

The expression can be expanded using difference of two squares;

[tex](a - b)(a + b) = a^2 - b^2[/tex]

By comparison, Expression 1 can be rewritten as

[tex](x - 1)^2 - (\sqrt{2})^2[/tex]

Open both brackets

[tex](x - 1)(x - 1) - (\sqrt{2})(\sqrt{2})[/tex]

Expand the above expression

[tex](x(x - 1) -1(x - 1)) - 2[/tex]

[tex](x^2 - x -x + 1)- 2[/tex]

[tex](x^2 - 2x + 1)- 2[/tex]

Remove bracket

[tex]x^2 - 2x + 1- 2[/tex]

[tex]x^2 - 2x - 1[/tex]

Hence,

If

[tex](x - 1 - \sqrt{2})(x - 1 + \sqrt{2})[/tex]  is a factor of p(x)

Then

[tex]x^2 - 2x - 1[/tex] is a factor of p(x)

Answer:

Both expressions are equal. One expression cannot be greater than the others.

Step-by-step explanation:

The given expressions are:

A:   (x + y)

B:   (x) + (y)

A:   (a+b) = a+b

B:   (a)+(b) = a+b

A:   (-a+ (-b)) = -a-b

B:   (-a)+(-b) = -a-b

A:   (a+(-b)) = a-b

B:   (a)+(-b) = a-b

A:   ((-a)+b) = -a+b

B:   (-a)+(b) = -a+b

We can see the pattern that both expressions are always equal to each other, no matter what value of x and y you plug in. One expression cannot be greater than the other

Answer:

x = -5

Step-by-step explanation:

Given that it is a vertical line, we know that it will only go through one x-value.

We are also given a point, (-5, -3).

This point tells us that the vertical line only goes through the x-value -5, so the equation will be x = -5.

Answer:   a = 2   b = 3   c = 5  

Literally a+ b+c = 10, but I don't think that's what the question means to ask.

the equation is 2x² +3x + 5

Step-by-step explanation:   Substitute the values of the given coordinates into the formula and use algebra (solve a system of equations by substitution and elimination) to get the values  of a,b & c

y=ax²+bx+c    using  (0,5), (1,10), and (2,19)

5=a(0)²+b(0)+c   becomes 5= 0+0 + c .so we find c = 5

10=a(1)²+b(1)+c    becomes 10 = a + b + c

19=a(2)²+b(2)+c .  becomes 19 = 4a + 2b + c

Substitute the 5 for c.  Then rewrite

10 = a + b + 5      becomes     5 = a+ b     to eliminate b multiply this be (-2)

(-2)( 5 = a+ b) .to get -10 = -2a - 2b  

19 = 4a + 2b + 5  becomes   14 = 4a + 2b  

_______________  Add these two

14 = 4a + 2b

-10 = -2a - 2b    this will eliminate the "b" term

4 = 2a       divide both sides by 2   so you have   a = 2  

substitute in 10=a(1)²+b(1)+5 to find b

10=2(1)²+b(1)+5 .becomes  5 = 2 + b   Subtract 2 from both sides

b = 3

So now you have all three values:  

a = 2  b= 3  c = 5

Answer:

The answer is 76.9 rounded or rounds.

Step-by-step explanation:

Solution

Given that:

Mean = μ = 72.5

Standard deviation = σ = 6.5

Now

By applying the standard normal table we have the following:

P(Z < z) = 75%

= P(Z < z)

= 0.75

Thus

z =0.67 by using the standard normal z table

Applying the  z-score formula we have:

x = z * σ + μ

x = 0.67*6.5+72.5

x= 76.855 ≈ 76.9

Therefore the cutoff time is 76.9 rounds.
