Mrs. Wadley bought 15 white shirts and 3 black shirts.

Step-by-step explanation:

Cost of one white shirt = $4

Cost of one black shirt = $5

Students in class = 18

Money spent on shirts = $75

Let,

white shirts = x

black shirts = y

According to given statement;

x+y=18     Eqn 1

4x+5y=75   Eqn 2

Multiplying Eqn 1 by 5;

[tex]5(x+y=18)\\5x+5y=90\ \ \ \ Eqn\ 3[/tex]

Subtracting Eqn 2 from Eqn 3;

[tex](5x+5y)-(4x+5y)=90-75\\5x+5y-4x-5y=15\\x=15[/tex]

Putting x=4 in Eqn 1

[tex]15+y=18\\y=18-15\\y=3[/tex]

Mrs. Wadley bought 15 white shirts and 3 black shirts.

Answer:

x=101/65, y=-16/65. (101/65, -16/65).

Step-by-step explanation:

4x+9y=4

9x+4y=13

----------------

9(4x+9y)=9(4)

-4(9x+4y)=-4(13)

------------------------

36x+81y=36

-36x-16y=-52

----------------------

65y=-16

y=-16/65

4x+9(-16/65)=4

4x-144/65=4

4x=4+144/65

4x=404/65

x=(404/65)/4=101/65

x=101/65, y=-16/65.

Answer:

1 month

Step-by-step explanation:

249 is the amount she spends for buying the kitten, (299-50=249) which she only has to pay once.

20 is the amount she has to spend every month, the rate of change.

The problem can be modeled with the general equation:

y = 20x + 249

In this equation, x the the time in months and y is the amount of money spent.

Substitute 250 for y.

y = 20x + 249

250 = 20x + 249    <= isolate x to get the number of months

1 = 20x

x = 1/20

Carol will only spent money every month, not for 1/20 of a month.

It will only take Carol 1 month to spent $250.

Check answer:

Substitute x for 1

y = 20x + 249

y = 20(1) + 249

y = 269

269 is more than 250 already.

-2/11

Answer:

(-1,5)

Step-by-step explanation:

The line x = -1 is a vertical line parallel to the y-axis.

Therefore, if the point Q(-1,5) reflects on line x = -1, then the y-coordinate of the image point will not change.

Again, as the point Q(-1,5) is on the line x = -1, therefore, the image will be the point itself i.e. (-1,5). (Answer)

The horizontal distance from point (-1,5) to the line x = -1 is zero.

Answer:

-34.72

Step-by-step explanation:

a + b + c = -44.84

a= 24.6

24.6 + b + c = -44.84

Since b = c (given "the other numbers are equal to each other")

Substitute b into c, we have

24.6 + b + b = -44.84 (b+b is the equivalence of 2 x b)

24.6 + 2b = -44.84 (subtract 24.6 from both sides)

2b = -69.44 (divide 2 from both sides)

b= -34.72

Since b = c  (given "the other numbers are equal to each other")

c is also -34.72

It looks like you want to multiply the two functions. If so, then,

(h*g)(x) = h(x)*g(x)

(h*g)(x) = (x-5)*|x|

(h*g)(x) = x|x| - 5|x|

Step-by-step explanation:

So 4:5:8

= 1:n:b

which means that 4/n= 1  

n= 1x4 so n=4

Now we know that 4 is divided by 4 to get 1, so we do the same for the other two values.

5/4= 1.25 and 8/4= 2

So now place the values for n:b

n= 1.25 b=2

So n:b= 1.25:2

To check, multiply each of the values in 1:1.25:2 by 4 and see if the answer you get is the same as 4:5:8.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Required percentage value = a

total value = b

Percentage = a/b x 100

The number of members in the drama club that are seventh graders is 14.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

5% = 5/100 = 1/20

We have,

Total number of members = 40

Percentage of members who is 7th graders = 35%

The number of 7th graders.

= 35% of 40

= 35/100 x 40

= 35/10 x 4

= 7 x 2

= 14

Thus,

The number of members in the drama club that are seventh graders is 14.

Answer:

A. f(2k)=0

Step-by-step explanation:

The factor theorem states that a polynomial f(x) has a factor (x−k) if and only if f(k)=0 (i.e. k  is a root).

If (x – 2k) is a factor of f(x), then by the factor theorem f(2k)=0 (i.e. 2k is a root).

Option A is true, f(2k)=0

Option B is false, it should be like in option A, f(2k)=0

Option C is false, because x=2k is a root, not x=-2k

Option D is false, because x-intercept of f(x) is x=2k, not y-intercept.

Figure represented the line y = -3x+4

Step-by-step explanation:

Given y=-3x+4 is equation of line

In order to graph the line, we need atleast two points

Now, When x = 0, y=?

y = -3x+4

y = -3(0) +4

y = 4

Point we get A(0,4)

Now, When x = 1, y=?

y = -3x+4

y = -3(1)+4

y = -3+4 = 1

Point we get B(1,1)

On graph, Locate points A(0,4) and B(1,1)

Draw a line passing through both of the points at once.

Answer:

[tex]\frac{1}{15}[/tex]

Step-by-step explanation:

In probability,

"AND" means "multiplication"

"OR" means "ADDITION"

We want probability of Blue Pen and Yellow Highlighter. So we find individual probabilities and "MULTIPLY" them.

Let P(b) be probability of blue pen

Let P(y) be probability of yellow highlighter

We know probability of event is that event divided by total number of that

So,

There are 4 + 2 = 6 pens

Blue pen = 2

Hence,

P(b) = 2/6 = 1/3

And,

There are 5 highlighters

Yellow highlighter = 1

Hence,

P(y) = 1/5

Now,

P(b and y) = 1/3 * 1/5 = 1/15

Hence,

probability of grabbing blue pen and a yellow highlighter is  [tex]\frac{1}{15}[/tex]

Irrational Number

Step-by-step explanation:

Answer:

C = 6 + 1.5h.

$6 is the fixed fee that the park charges.

And $1.5 is the rate of charge per hour for rent of the raft.

Step-by-step explanation:

The water park charges a rental fee plus $1.5 per hour to rent inflatable rafts.

Let the total charge (C) has a linear relationship with the number of hours (h) spent in the park and it is C = a + bh ......... (1)

Now, b is the rate of charge to rent inflatable rafts and b = $1.5 per hour.

So, C = a + 1.5h ........... (2)

Now, given that the total cost to rent a raft for 6 hours is $15.

So, from equation (2) we get,

15 = a + 1.5 × 6

⇒ a = 6

Therefore, the equation (2) becomes C = 6 + 1.5h.

Here, $6 is the fixed fee that the park charges.

And $1.5 is the rate of charge per hour for rent of the raft. (Answer)
