Answer:

{ x | -3 <= x < +1 }

Step-by-step explanation:

We note that the graph occupies from x=-3 to x=+1, while -3 is a value included (endpoint is solid), and +1 is excluded (endpoint hollow).

Thus the domain is { x | -3 <= x < +1 }

Answer:

y = 2x - 8

Step-by-step explanation:

y = 2x + b

-2 = 2(3) + b

-2 = 6 + b

-8 = b

Answer: 70$

Step-by-step explanation: Hope this helps <3

Hey there!

-2<3x+1

= 3x + 1 < -2

SUBTRACT 1 to BOTH SIDES

3x + 1 - 1 < -2 + 1

CANCEL out: 1 - 1 because that gives you 0

KEEP: -2 + 1 because that helps you solve for x

-2 + 1 = -3

New EQUATION: 3x > -3

DIVIDE 3 to BOTH SIDES

3x/3 > -3/3

CANCEL out: 3/3 because that gives you 1

KEE3 -3/3 because that helps us compare for x

-3/3 = -1

Answer to the equation: x > -1

OVERALL Answer: x > -1; It is an OPENED circle shaded to the right starting at -1 (Option A.)

Good luck on your assignment and enjoy your day!

Answer:

12 meters

Step-by-step explanation:

We can solve this problem simply by dividing area by the known width value (because length x width = area):

96/8 = 12

Answer:

The correct option is - D.

Step-by-step explanation:

To find - Select the correct answer. The parent tangent function is transformed such that its period is halved. Which graph could represent the transformed function?

Solution -

We know that,

The parent tangent function is -

f(x) = tan(x)

Period of Parent function = [tex]\pi[/tex]

Now,

If Period is half,

Then

The function is transformed to

f(x) = tan(2x)

So,

The graph becomes

The correct option is - D.

Step-by-step explanation:

The statement that is supported by the information in his graphs is C. It can be inferred that pizza and chicken nuggets should be the only meals offered in the cafeteria to please the most students each day.

This refers to the use of evidence to support a claim based on available data to show its validity.

Hence, we can see that from the information in the graphs, we can see that 50% of students prefer using trays and they represent half of the students from the students that prefer trays, they prefer to eat pizza and chicken nuggets and option C is the correct answer.

Answer:

D

Step-by-step explanation:

1. Make it into a y = x equation

       y = 9x +7

2. change x to y and y to x

       x = 9y + 7

3. Isolate y ( if not possible, use implicit differentiation but here you can)

      x-7 = 9y

      1/9x-7/9 = y

Step-by-step explanation: The formula for the volume of a rectangular prism is given as: Volume of a rectangular prism = (length x width x height) cubic units. So try The length, width, and height of a rectangular prism are 15 cm, 10 cm, and 5 cm, respectively.

Answer:

 320 cu. yd.      

Step-by-step explanation:

V = Bh   where B is the area of the base (triangle) and h is the height of prism

B = bh/2 = 8(8)/2 = 64/2 = 32

height of prism = 10

V = 32(10) = 320 cu. yd.

Answer:

The hypotenuse is 10 cm long.

Step-by-step explanation:

We can find the hypotenuse by using the following formula where "c" is the length of the hypotenuse and "a" and "b" are the lengths of the legs.

[tex]c = \sqrt{a^{2} + b^{2} }[/tex]

Now we just substitute the values and get...

[tex]c = \sqrt{a^{2} + b^{2} }\\c = \sqrt{6^{2} + 8^{2} } \\c = \sqrt{36 + 64} \\c = \sqrt{100} \\c = 10[/tex]

Therefore the hypotenuse is 10 cm long.

Answer:

[tex]d(P,Q) = \sqrt{34}[/tex]

The midpoint of the segment is M(27.5, -13.5).

Step-by-step explanation:

Distance between two points:

Suppose that we have two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:

[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Distance between P(25,-15) and Q​(30,-12)

[tex]d(P,Q) = \sqrt{(30-25)^2+(-12-(-15))^2} = \sqrt{34}[/tex]

So

[tex]d(P,Q) = \sqrt{34}[/tex]

Coordinates of the midpoint M of the segment PQ.

Mean of the coordinates of P and Q. So

[tex]x_M = \frac{25+30}{2} = \frac{55}{2} = 27.5[/tex]

[tex]y_M = \frac{-15-12}{2} = -\frac{27}{2} = -13.5[/tex]

The midpoint of the segment is M(27.5, -13.5).

Answer:

AB = 3π units

Step-by-step explanation:

Next time please share the entire set of instrutions.

x^2 - 9x - 15 = -5 should be rewritten in standard quadratic form:

x^2 - 9x - 10 = 0 = (x - 10)(x + 1) = 0.

Setting each factor equal to zero and then solving for x yields {-1, 10}

Answer:

{-1,10}

Step-by-step explanation:

[tex]x^2-9x-15=-5[/tex]   given
