x = -3 + 5y - 6 for y

Answer:

a

Step-by-step explanation:

Answer: Top right graph.

Step-by-step explanation:

The function ⌊x⌋ rounds the value x to the lower whole number.

for example:

⌊1.5⌋ = 1

⌊1.923⌋ = 1

⌊2.0⌋ = 2

then, the graph of ⌊x⌋ will be a black dot in the each whole number, and a horizontal segment to the right that ends with a white dot in the next whole number. Right above the white dot, we have another black dot, and it repeats.

if we have ⌊x⌋ + 2, we move te previous graph 2 units upwards, then the correct option is the top right graph.

You can check some points if you like:

f(0) = ⌊0⌋ + 2 = 2

f(0.5) = ⌊0.5⌋ + 2 = 2

f(1) = ⌊1⌋ + 2 = 3

So in x = 0 we have a black dot in y = 2, and in x = 1 we have a white dot in y = 2 and a black dot in y = 3.

Answer:

c

Step-by-step explanation:

because Ax+Bx=Cx^2

Answer: "p divided by 11" or "p over 11" or "p by 11".

Step-by-step explanation:

We use mathematical statements to express any algebraic expression.

For example: We write 2x as "2 is multiplied by x " or " product of 2 and x".

p+q as "sum of p and q" or "p is added to q"

The given expression is : [tex]\dfrac{p}{11}[/tex]

In mathematical statements, it can be written as "p divided by 11" or "p over 11" or "p by 11".

Hence, the statements are equal to the expression  [tex]\dfrac{p}{11}[/tex] are "p divided by 11" or "p over 11" or "p by 11".

Answer:

The picture is attached!

Step-by-step explanation:

For c, the last bracket said (y=6) and I assumed that it is (y+6).

If it is (y-6), the answer would change, so please tell me if I am wrong.

Answer:

t=4.19 seconds

Step-by-step explanation:

Distance varies directly with the square of the time of the fall

It means,

D=kt^2

18ft in 2 seconds

D=kt^2

18=k*2^2

18=4k

k=18/4

=9/2

k=9/2

D=kt^2

D=79feet

79=9/2t^2

t^2=79÷9/2

t^2=79×2/9

=158/9

t=√158/√9

t=12.57/3

t=4.19 seconds

Answer:

1089

Step-by-step explanation:

The original number is A0CD, We have that DC0A = 9 x A0CD.

If A =1, then D = 9 and we have:

9C01 = 9 x 10C9

In order for this expression to be true, the following must also be true:

(C x 9) + 8 must be divisible by 10, which means that C x 9 must end in a 2.

The only multiple of 9 (from 9 to 81) that ends in a 2 is 72.

72 = 9 x 8.

Therefore, C must be 8 and the original number is 1089. Multiply it by 9 to check the answer:

1089 x 9 = 9,081

Therefore, 1089 is correct.

The area of the shaded region will be 18 ³/₄ π square units. Then the correct option is A.

Let r be the radius of the sector and θ be the angle subtended by the sector at the center. Then the area of the sector of the circle will be

Arc = (θ/2π) πr²

The central angle of the shaded region is (3/2)π radian. And the diameter of the sector is 10 units. Then the radius of the sector is given as,

r = d / 2

r = 10 / 2

r = 5 units

The area of the shaded region is given as,

A = ((3/2)π/2π) π (5)²

A = 25 x (3/4)π

A = (75/4)π

A = 18 ³/₄ π square units

The area of the shaded region will be 18 ³/₄ π square units. Then the correct option is A.

The sum of the angles of a triangle are 180

1x+5x+6x = 180

Combine like terms

12x = 180

Divide by 12

12x/12 = 180/12

Answer:

22 is diametrically opposite of 7

Step-by-step explanation:

A circle has a total of 360º

The circumference of the circle has 12 equally spaced points

Each point on the circumference=360°/30

= 12º per point

A point (n) opposite to 7 on the circumference will form 180° line on the circle, that is half of the circle.

Half of the circle=30 points/2

=15 points

Therefore,

15+7=22

22 is diametrically opposite 7

Answer:

A

Step-by-step explanation:

Since combining the equations will result to 0 = -12, it means that there are: A. no solutions to the system because the linear equations represent parallel lines.

Therefore, since the system of linear equations given have the same slope, the lines of both equations are parallel and cannot intersect.

Thus, since combining the equations will result to 0 = -12, it means that there are: A. no solutions to the system because the linear equations represent parallel lines.

Answer:

62.17 days

Step-by-step explanation:

The computation of the number of days  is shown below:

Given that

A(t)=10 × 0.5^(t ÷ 18.72)

1 = 10 × 0.5 ^ (t ÷ 18.72)

0.1 = 0.5 ^ (t ÷ 18.72)

Now consider the log in both sides

ln(0.1) = ln(0.5)^ (t ÷ 18.72)

ln(0.1)  ÷  ln(0.5) = (t ÷ 18.72)

3.321928095  = (t ÷ 18.72)

So, t = 62.17 days

[tex]P=0.1833[/tex]

Step-by-step explanation:

The number of ways or combinations in which we can choose x elements from a group of n is calculated as:

[tex]nCx=\frac{n!}{x!(n-x)!}[/tex]

So, the probability that none of the damaged houses are insured can be calculated as:

[tex]\frac{kC3}{10C3}=\frac{kC3}{120}[/tex]

Because there are 120 ways to select 3 houses from the block of 10 houses and there are kC3 ways to select 3 houses from a group of k houses that are not insured.

The probability that none of the damaged houses are insured is 1/120, so:

[tex]\frac{kC3}{120}=\frac{1}{120}\\ kC3=1[/tex]

kC3 is equal to 1, only if k is equal to 3. It means that there are 3 houses that are not insured.

Then, the probability that one of the damaged houses is insured can be calculated as:

[tex]\frac{3C2*7C1}{10C3}=0.175[/tex]

Because we select 2 houses from the 3 that are not insured and select 1 house from the 7 that are insured.

Finally, the probability that at most one of the damaged houses is insured is equal to the sum of the probability that one of the damaged houses is insured and the probability that none of the damaged houses is insured. It is equal to:

[tex]P=\frac{1}{120}+0.175=0.1833[/tex]

4 = 2 × 2 = 2²

36 = 6 × 6 = 6²

64 = 8 × 8 = 8²

121 = 11 × 11 = 11²

other examples of perfect squares are

1 × 1 = 1 = 1²

3 × 3 = 9 = 3²

4 × 4 = 16 = 4²

5 × 5 = 25 = 5²

Answer:

2 x - y = - 2 and 22 x + 10 y = 7

Step-by-step explanation:

To find the equation to produce a solution of approximately (–0.3, 1.4), we have to solve the equations simultaneously.

a) For line 2 x - y = - 2 and 22 x + 10 y = 7

Multiply line 1 by 10 to give : 20x - 10y = -20

Add 20x - 10y = -20 and 22 x + 10 y = 7 to get:

42x = -13

x = -13/42 = -0.3

Put x = -0.3 in 2 x - y = - 2  to get:

2(-0.3) - y = - 2

-0.6 - y = -2

y = 2 - 0.6 = 1.4

x = - 0.3 and y = 1.4

This is the correct option

b) For line 3 x + 2 y = 5 and 4 x - y = 2

Multiply line 2 by 2 to give : 8x - 2y = 8

Add 8x - 2y = 48 and 3 x + 2 y = 5 to get:

11x = 13

x = 13/11 = 1.2

Put x = 1.2 in 3 x + 2 y = 5  to get:

3 (1.2) + 2 y = 5

y = 1.4

x = 1.2 and y = 1.4

c)  For line 4 x - y =  2 and 22 x + 10 y = 7

Multiply line 1 by 10 to give : 40x - 10y = 20

Add 40x - 10y = 20 and 22 x + 10 y = 7 to get:

62x = 27

x = 0.44

Put x = 0.44 in 4x - y =  2  to get:

y = -0.24

d) For line 2 x - y = - 2 and 3 x + 2 y = 5

Multiply line 1 by 2 to give : 4x - 2y = -4

Add 4x - 2y = -4 and 3x + 2 y = 5 to get:

7x = 1

x = 0.14

Put x = 0.14 in 2 x - y = - 2  to get:

Answer:

a) Which item’s price was reduced by more, and by how many dollars more was it reduced?

The DVD player's price was reduced more by $3.82 than the stereo tuner's price.

b) Round all dollar values to the nearest cent.

Rounding $3.82 dollars to the nearest cents

$1 = 100 cents

$3.82 =

3.82 × 100 cents

= 382 cents

The DVD player's price was reduced by 382 cents more than the stereo tuner's price

Step-by-step explanation:

Lets day the original price of the DVD player was $100

We are told the price was marked down to 36%

36% of $100 = $36

$100 - $36 = $64

We are told the DVD cost $41.60 after the markdown.

Original cost of DVD =

$41.60/$64 × 100 = $65

Lets the original price of the Stereo player was $100

We are told the price was marked down to 22%

22% of $100 = $22

$100 - $22 = $78

We are told the DVD cost $69.42 after the markdown.

Original cost of Stereo =

$69.42/$78 × 100 = $89

DVD = $65 - $41.60 = $23.40 less 

Stereo = $89 - 69.42 = $19.58 less

Difference between the DVD and the Stereo is

$23.40 - $19.58 = $3.82

Therefore,the DVD player's price was reduced by $3.82 more than the stereo tuner's price

Rounding $3.82 dollars to the nearest cents

$1 = 100 cents

$3.82 =

3.82 × 100 cents

= 382 cents
