Answer:

C

Step-by-step explanation:

Each of the tables is a linear relationship. Linear relationships increase or decrease steadily by adding or subtracting a constant. Table A increases by 5. Table B decreases by 2. Table C doesn't change. Table D increase by 4.

A "no change" means the y values never change. The constant is 0 and is a horizontal line. Table C is the solution.

Answer:

Option C.

Step-by-step explanation:

Linear relationship : If the relation between variables is represent by a non vertical straight line, then it is called a  linear relationship.

Horizontal line is a special case of linear relationship. It is know as no change linear relationship. It means the output value remains same for each input value.

In option C, the given table is  

x      y

14    12

20   12

26   12

32   12  

Only in option C, the y-values are constant. So, it represents no change linear relationship.

Therefore the correct option is C.

The function could be used to model this situation is D. y = 2ˣ.

The function that could be used to model the situation where the number of bacteria, y, in a certain area doubles every hour, x, is: D. y = 2ˣ

This function represents exponential growth, where the number of bacteria doubles every hour.

The variable x represents the number of hours, and 2^x represents the doubling of the bacteria population over time.

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

According to the question

Louis spins the spinner twice.

Total number of favorable outcomes = {OB, OO, OB,OG, BB, BO, BB, BG, GG, GB, GO, GB, BB, BO, BB, BG} = 16

P(both green) :

Number of favorable outcomes = 1

P(both green) = [tex]\frac{1}{16}[/tex]

It is applicable.

P(both blue) :

Number of favorable outcomes = 4

P(both blue) = [tex]\frac{4}{16}[/tex] = [tex]\frac{1}{4}[/tex]

It is applicable.

P(first green and then blue) :

Number of favorable outcomes = 1

P(first green and then blue) =  [tex]\frac{1}{16}[/tex]

P(first orange and then blue) :

Number of favorable outcomes = 2

P(first orange and then blue) =  [tex]\frac{2}{16}=\frac{1}{8}[/tex]

It is applicable.

P(first orange and then green) :

Number of favorable outcomes = 1

P(first orange and then green) =  [tex]\frac{1}{16}[/tex]

Hence,

P(both green) : [tex]\frac{1}{16}[/tex], P(both blue) : [tex]\frac{1}{4}[/tex], P(first orange and then blue) : [tex]\frac{1}{8}[/tex]

These probabilities are correct.

Answer:

A

Step-by-step explanation:

With this question, its actually way easier than you think. If you want to find corresponding angles, you have to find a way to make the shapes overlap to be exactly the same. If they cannot be exactly the same, there will not be corresponding angles. For this, if you rotate quadrilateral 90 degrees counter-clockwise, you will see that the shapes look the same. Then you can just match up the angles that have the same degree measure (or just look the same for simplicity) and you have your answer. The answer is actually in the question too. ABCD=JKLM, but each letter is actually in the right place. A=J B=K C=L D=M.

Laura has a $5,500 liability because that's what she owes and she is liable for it. She hasn't paid for it fully so the car has not become an asset. The answer is C.

Hope this helps

Answer:

I think th answer is A

Explanation:

Asset is a valuable or useful thing. The car is worth 18,000 so it is the asset. Liability is being responsible for things like debt, or something you own by law. She is responsible for the $5,500 she owes, so that is the liability. Hope this helps!

Answer:

y = -4x - 38

Step-by-step explanation:

Parallel lines are parallel because they never intersect. As such, they have the same slope. The slope of the line y = -4x + 1 is -4. Substitute m = -4 and the point (-9,-2) into the point slope form of a line.

[tex]y -y_1 = m(x-x_1)\\y --2 = -4(x --9)\\y + 2 = -4(x+9)\\[/tex]

Apply the distributive property to find the slope intercept form.

y + 2 = -4(x+9)

y + 2 = -4x - 36

y = -4x - 38

Answer:

[tex]f(7)=\frac{-5}{3}[/tex] or [tex]f(7)=-1.67[/tex]

Step-by-step explanation:

We are given the following function of x and we are to find the value of [tex] f ( 7 ) [/tex]:

[tex] f ( x ) = \frac { 3 } { x + 2 } - \sqrt { x - 3 } [/tex]

Substituting the given value (7) in the above function to get:

[tex]f(x)=\frac{3}{x+2}-\sqrt{x-3}[/tex]

[tex] f ( 7 )= \ frac{3}{7+2}-\sqrt{7-3}[/tex]

[tex] f(7) = \frac { 3 } { 9 } - \sqrt { 4 } [/tex]

[tex]f(7)=\frac{1}{3}-2[/tex]

[tex]f(7)=\frac{1}{3}-\frac{6}{3}[/tex]

[tex]f(7)=\frac{-5}{3}[/tex] or [tex]f(7)=-1.67[/tex]

Answer:

2 hours per day

Step-by-step explanation:

19.5 - 5.5 = 14

14 / 7 = 2 hours per day

Mary needs to rehearse 2 hours per day for the next 7 days to meet her total rehearsal goal.

To calculate the total rehearsal time for Mary:

She has rehearsed for 5.5 hours.

She wants to rehearse a total of 19.5 hours.

Therefore, 19.5 - 5.5 = 14 hours

She needs to rehearse an additional 14 hours in the upcoming week.

To find out how many hours Mary must rehearse per day in the next 7 days:

14 / 7 = 2 hours/day

Answer: Madeline is 20 yrs old

Step-by-step explanation:

If Laura is 50 and she is 10 years older than Raena then Raena is 40 that would then make Madeline 20 years old.

Final answer:

To determine Madeline's age, we set up an equation based on the given relationship and solved it to find that Madeline is 20 years old.

Explanation:

To solve the question about Raeana, Madeline, and Laura's ages, we first define the variables. Let's denote Madeline's age as M. Since Raeana is twice as old as Madeline, Raeana's age would be 2M.

The problem states that Laura is 10 years older than Raeana, making Laura's age 2M + 10. Given that Laura is 50 years old, we can set up an equation: 2M + 10 = 50.

Now, we solve for M:
Subtract 10 from both sides of the equation to isolate the term with M on one side: 2M = 40.

Divide both sides by 2 to solve for M: M = 20.

Therefore, Madeline is 20 years old.

QUESTION 1

If f(x)=1-x² and g(x)=1-x,

Then,

(f-g)(x)=f(x)-g(x)

This implies that,

[tex]( f - g)(x) = 1 - {x}^{2} - (1 - x)[/tex]

[tex]( f - g)(x) = 1 - {x}^{2} - 1 + x[/tex]

We simplify to get,

[tex]( f - g)(x) = - {x}^{2} + x[/tex]

The correct choice is B.

QUESTION 2

Given:

f(x)=3+x

and

[tex]g(x) = {x}^{2} + 1[/tex]

[tex](f\circ g)(x)=f(g(x))[/tex]

[tex](f\circ g)(x)=f( {x}^{2} + 1 )[/tex]

[tex](f\circ g)(x)=3 + {x}^{2} + 1[/tex]

[tex](f\circ g)(x)= {x}^{2} +4[/tex]

Also,

[tex](g\circ f)(x)=g(f(x))[/tex]

[tex](g\circ f)(x)=g( 3+ x)[/tex]

[tex](g\circ f)(x)= {(3 + x)}^{2} + 1[/tex]

[tex](g\circ f)(x)= 9 + 6x + {x}^{2} + 1[/tex]

[tex](g\circ f)(x)= {x}^{2} + 6x + 10[/tex]

The unit price of one pencil is $0.60.

The cost of one pencil (the unit price) can be found by dividing the total cost by the number of pencils. In this case, we have $3.60 divided by 6. This gives us a unit price of $0.60 per pencil.

Circumference= [tex]2\pi r[/tex]

If the diameter is 6 the radius will be 3

[tex]2\pi (3)[/tex]

Circumference= 18.85

Hey there!

The formula for circumference is πd, where d is diameter.

We are given that the diameter is 6, so the circumference is 6π.

However, we are asked for the approximate circumference, not the exact.

So, let's use 3.14 as π and simplify.

6 x 3.14 = 18.84

The approximate circumference of a circle with the diameter of 6 is 18.84.

Answer:

San Fransisco

Step-by-step explanation:

If Geneva is 12°C colder than her hometown, this means that her hometown is 12°C warmer than -3°C.

Since warmer means a higher number, we find 12 + -3, which is 9°C.

The town that is 9°C is San Fransisco.

A rotation doesn't change the length of anything.

The length of the rotated line segment would be the same as the original line segment.

Because both Y values are the same, you just need to calculate the length of the X values.

5 to 0 = 5

0 to -6 = 6

Total length = 5 +6 = 11 units long.

Answer:

So option B is the correct answer .

Step-by-step explanation:

Since it is the multiplication of 1 X 3 matrix to 3 X 3 order matrix,

so the resultant product should be 1 X 3 because when we multiply two matrices it is the condition that if A is of order p X q and B is of order q X r,

the product matrix (suppose C ) will be of order p X r.

so the product will be

= [-1*3+2*2+4*0   -1*6+2*4+4*6   -1*1+2*0+4*2]

= [ 1      26     7] .

Step-by-step explanation:

Factorise the numerators on both fractions

a² + 10a + 25 = (a + 5)(a + 5) ← perfect square

a² - 25 = (a - 5 )(a + 5) ← difference of squares

To divide, leave the first fraction, change division to multiplication and turn the second fraction upside down.

Hence

= [tex]\frac{(a+5)(a+5)}{a+5}[/tex] × [tex]\frac{a-5}{(a-5)(a+5)}[/tex]

Cancel both the (a + 5) factors on the numerator/ denominators and the (a - 5) factor on the numerator/denominator, leaving

Answer:

545454

Step-by-step explanation:

This is a ratio.  you take 666/333 = x/272727.  Basically tis says 666 cm to 333 m is equal to some number of centimeters to 272727 meters.  Then just solve for x.  272727(666/333) = 545454.

Another way of looking at it is what did we multiply 333 by to get 666.  Answe is 2, so we do the same  for 272727.  2*272727 = 545454

If you wanted to you could have also converted units so everything was in either centimeters of meters, but as long as you keep things in the right order this works.  

Answer: the number of centimetres is 54cm

Step-by-step explanation:

Given that 6 centimeters represents 3meters.

The number of centimeters on the blue print that will represent an actual distance of 27meters will be Y

6 : Y = 3 : 27

That is

6/Y = 3/27 = 1/9

Definitions of parallelogram and rectangle:

A parallelogram is a quadrilateral in which both pairs of opposite sides are parallel.

A rectangle is a parallelogram with four right angles.

This gives us that each rectangle is a parallelogram.

But an arbitrary parallelogram can have angles that are not necessarily right (for example, 60°, 120°, 60°, 120°). Thus, there are a lot of parallelograms that are not rectangles.

Trapezoid

Step-by-step explanation:

The points are shown in the attached graph.

You can clearly see from the picture that it is a "Trapezoid".

Trapezoid is basically a quadrilateral (4 sided-figure) that has 1/2 pair of parallel sides.

On the other hand, a parallelogram has 2 pair of parallel sides.

Thus, a parallelogram is a special type of trapezoid where there are 2 pair of parallel sides. But trapezoid need not be a parallelogram.

The picture shows 1 pair of parallel sides, hence it is a trapezoid.
