Answer:

[tex] - 23x(x + 3) \\ { - 23x}^{2} - 69x \\ \\ \\ \\ \\ \\ hope \: it \: helps \\ stay \: safe \: healthy \: nd \:and \: happy[/tex]

Answer:

[tex]-23x^{2} -69x[/tex]

Step-by-step explanation:

Using the distributive property:

[tex]-23x(x+3)[/tex]

You will multiply both the x and the 3 inside the parantheses by the -23x outside.

[tex]-23x[/tex] · [tex]x = -23x^{2}[/tex]

Then:

[tex]-23x[/tex] · [tex]3 = -69x[/tex]

If you combine both you will recieve:

[tex]-23x^{2} -69x[/tex]

9f =49.6-3.7

9f=45.9

f = 5.1

Answer:

False

Step-by-step explanation:

1+1=2 is clearly true.

2+3=4 is clearly false.

x if and only if y has a value of true if x and y are both true or both false. It is false otherwise.

So, true if and only if false has a value of false, so the answer is [tex]\boxed{false}[/tex]

Answer: 65

Step-by-step explanation:

all angles of a triangle will add up to be 180 degrees there for add 80 + 35 to get 115 degrees and then subtract 115 from 180(180-115) to get the third angle of 65 degrees

Answer:

65

Step-by-step explanation:

80+35+?=180

115+?=180

115-115+?=180-115

?=65

Answer:

Value of f(-10) is 1100

Step-by-step explanation:

Given that f(x) = x² - x³

Here we need to find f(-10).

 f(-10) =  (-10)² - (-10)³

 f(-10) = 100 - (-1000)

 f(-10) = 100 + 1000

 f(-10) = 1100

Value of f(-10) is 1100

Answer:

104

Step-by-step explanation:

∠JTS = ∠SRT  + ∠TSR   {exterior angles equals sum of opposite interiror angles}

27x - 4 = 18x + 2 + 30

27x  - 4 = 18x + 32

Add 4 to both sides

27x = 18x + 32 + 4

27x = 18x + 36

Subtract  18x from both sides

27x - 18x = 36

9x = 36

Divide  both sides by 9

x = 36/9

x = 4

∠JTS = 27x - 4

         = 27*4 - 4

         = 108 - 4

        = 104

Answer:

Step-by-step explanation:

A function is one-to-one if it passes the horizontal line test.  This is the case if a horizontal line intersects the graph in only one place.  

The graph of f(x) = x^2 - 5 is that of a parabola that opens upward.  There are several possibilities here:

1.  The horizontal line intersects the parabolic graph twice on the interval (-infinity,+infinity).  Therefore this function is not one-to-one on this interval

(-infinity,+infinity).

2. If we define the domain as [0,+infinity), a horizontal line will intersect this parabolic graph only once.  Therefore this function is one-to-one on [0,+infinity).

Answer:

General Formulas and Concepts:

Order of Operations: BPEMDAS

Rewriting Fractions

Step-by-step explanation:

Step 1: Define

1 2/3 ≥ r - 7/12

Step 2: Solve for r

Rewrite:                    5/3 ≥ r - 7/12

Isolate r:                    9/4 ≥ r

Rewrite:                    r ≤ 9/4

Reduce:                    r ≤ 2 1/4

Here we see that any number r less than or equal to 2 1/4 will work as a solution to the inequality.

Answer:

[tex]x<3[/tex]

Step-by-step explanation:

[tex]3\left(x-9\right)<-18[/tex]

Divide both sides by 3

[tex]\frac{3\left(x-9\right)}{3}<\frac{-18}{3}[/tex]

[tex]x-9<-6[/tex]

Add -9 to both sides:

[tex]x-9+9<-6+9[/tex]

[tex]x<3[/tex]

Answer:

the one on the right looks best for the slope because the slope is a lot larger than the one on the right the one on the right is smaller but a few inches few times I don't know you might want to check it before I actually answer it for you so I hope you found this kind of helpful thank you bye

[(x+6)(x-3)]²

= x⁴+6x³-27x²-108x+324

Answer:

y=-3x+1

Step-by-step explanation:

1) the slope-interception form is: y=slope*x+intercept;

2) if A(0;1) and B(2;-5) then it is possible to make up the equation of the required line:

[tex]\frac{x-X_A}{X_B-X_A} =\frac{y-Y_A}{Y_B-Y_A}; \ => \ \frac{x}{2}=\frac{y-1}{-6};[/tex]

3) the equation in the item 2 can be written in slope-interception form:

x=(y-1)/(-3); ⇔ y-1= -3x; ⇔ y= -3x+1.

P.S. note, the suggested way of solution is not the shortest one.

Answer:

Step-by-step explanation:

Given that :  

Total point = 867  

Let :  

number of 3 point goals = p  

Number of 2 point goals = 2p - 66  

Number of 1 point goals = (2p - 66) - 36 = 2p - 102  

Hence,  

3p + 2(2p - 66) + 2p - 102 = 867  

3p + 4p - 132 + 2p - 102 = 867  

3p + 4p + 2p - 234 = 867  

9p - 234 = 867  

9p = 867 + 234  

9p = 1101  

p = 122.33  

2 pointer = 2p - 66  

2(122.33) - 66 = 178.67  

1 point = 2p - 102  

2(122.33) - 102  

= 142.67

Given that :  

Total point = 867  

Let :  

number of 3 point goals = p  

Number of 2 point goals = 2p - 66  

Number of 1 point goals = (2p - 66) - 36 = 2p - 102  

Hence,  

3p + 2(2p - 66) + 2p - 102 = 867  

3p + 4p - 132 + 2p - 102 = 867  

3p + 4p + 2p - 234 = 867  

9p - 234 = 867  

9p = 867 + 234  

9p = 1101  

p = 122.33  

2 pointer = 2p - 66  

2(122.33) - 66 = 178.67  

1 point = 2p - 102  

2(122.33) - 102  

= 142.67

Answer:

(-1,-5)

Step-by-step explanation:

Graph both lines and find the intersection.

The midpoint of the x values a and -a would be 0 because of a was a number the mid point between the negative and positive of the same number is 0

The midpoint of 2b and 8b is found by adding them together and dividing by 2:

2b + 8b = 10b / 2 = 5b

The midpoint is (0,5b)

Answer:

85

Step-by-step explanation:

The sum of two interior angles in a triangle is equal to an exterior angle that is supplementary to the third interior angle.

As you can see in the attached image we can find the measure of the interior angle using the straight line and find the value of missing angle

25 + 60 = 85
