Answer:

D and C

Step-by-step explanation:

1) The answer is D

g(x) = 2x-8 if we put the corresponding values of x in the table we get the exact same values of y example

[tex]g(x)=2x-8\\g(5)=2(5)-8\\g(5)=2\\g(7)=2(7)=8\\g(7)=6[/tex]

so we can see that our values match with the table's values for part D)

2)The answer is C

Range corresponds to the values of y and here the function in the image shows the maximum value of y is 2 and then it decreases to 1 , 0 , -1 and so on so option C is correct y<2

1 and 2/5 and 2 and 2/5

A fraction represented with its quotient and remainder is a mixed fraction. 1 2/5 and 2 2/5 are two mixed numbers that have a sum of 3 4/5.

What is Mixed Fraction?

A fraction represented with its quotient and remainder is a mixed fraction.

We need to find the two mixed numbers whose sum is 3 4/5.

The sum of two mixed numbers is 3 4/5 which is also equal to 19/5.

1 2/5+2 2/5

=7/5+12/5

=19/5

Now 3 4/5=19/5

Therefore 1 2/5 and 2 2/5 are two mixed numbers whose sum is 3 4/5

He rented the bike for 6 hours.

Step-by-step explanation:

To solve this you would first subtract the initial amount which is $18 to $48. You would then divide 5 by $30 Since you have to pay $5 per hour, and you would end up with 6 which is the number of hours that willie rented the bike for.

Answer:

40 girls

Step-by-step explanation:

Set up a proportion where x is the number of girls in band class:

[tex]\frac{3}{5}[/tex] = [tex]\frac{24}{x}[/tex]

Cross multiply and solve for x:

3x = 120

x = 40

So, there were 40 girls in band class.

Answer: There are 40 girls in band class.

____________________________________________________________

The ratio for this problem is:

[tex]\frac{3}{5} = \frac{24}{x}[/tex]

To get from 3 to 24, you would multiply by 8. You need to do the same thing to 5 to get x.

5 times 8 equals 40.

There are 40 girls in band class.

Answer:

x = 6

Step-by-step explanation:

Since the triangles are isosceles the two bottom angles are equal. So, 71 + 71 + 2 + 6x would help us find x. Now to solve it.

71 + 71 + 2 + 6x = 180

142 + 2 + 6x = 180

144 + 6x = 180

6x = 180 -144

6x/6 = 36/6

x = 6

Answer:

<ECF = 45 degrees

Step-by-step explanation:

If ABCD is a square, then the diagonal AC divides angle <C and angle <A  in two equal parts. Angles A and C are also 90 degrees each due to the act that the figure is a square. Therefore their bisection would render 90/2 = 45 degrees.

Notice as well that angle <ECF is opposite by the vertex to one of these 45 degree angles, and then it must measure the same amount (45 degrees).

So, <ECF = 45 degrees

I hope I helped sorry if I didnt

Answer:

Chris sells 5 tickets and Mary sells 16 tickets

Step-by-step explanation:

System of Equations

To solve the problem we call:

x = number of tickets sold by Chris

y = number of tickets sold by Mary

They sold a total of 21 tickets, thus:

x + y = 21            [1]

Mary sold adult tickets for $6.50 each and Chris sold student tickets for $4.00 each. The total income was:

4x + 6.5y = 124       [2]

Multiplying [1] by -4:

-4x - 4y = -84            [3]

Adding [2] and [3]:

2.5y = 40

Dividing by 2.5:

y = 40/2.5

y = 16

From [1]

x = 21 - 16 = 5

x = 5

Chris sells 5 tickets and Mary sells 16 tickets

Answer:

b. -2,-4,-8,-16,-32 thats the answer i think

The arithmetic sequences are:

B) -2, -4, -8, -16, -32, ...

C) 0, 6, 12, 18, 24, ...

The correct options are B and C.

A series of integers called an arithmetic progression or arithmetic sequence (AP) has a constant difference between the terms.

An arithmetic sequence is a sequence of numbers where each term is obtained by adding a fixed number, called the common difference, to the previous term. We can check which of the given sequences satisfy this definition:

A) 0, 5, 11, 18, 24, ...

The common difference between consecutive terms is not the same: the difference between the first two terms is 5, the difference between the second and third terms is 6, the difference between the third and fourth terms is 7, and so on. Therefore, this sequence is not an arithmetic sequence.

B) -2, -4, -8, -16, -32, ...

The common difference between consecutive terms is multiplied by -2: the difference between the first two terms is -2(-2) = 4, the difference between the second and third terms is -4(-2) = 8, the difference between the third and fourth terms is -8(-2) = 16, and so on. Therefore, this sequence is an arithmetic sequence with a common difference of -2.

C) 0, 6, 12, 18, 24, ...

The common difference between consecutive terms is 6. Therefore, this sequence is an arithmetic sequence with a common difference of 6.

D) 1, -3, 9, -27, 81,...

The common difference between consecutive terms is multiplied by -3: the difference between the first two terms is -3, the difference between the second and third terms is -3(-3) = 9, the difference between the third and fourth terms is -9(-3) = 27, and so on. Therefore, this sequence is not an arithmetic sequence.

Therefore, the arithmetic sequences are options B and C.

Answer:

b

 Step-by-step explanation:

We are given the equation:

25 - b² = 4b

it can be simplified into the following:

b² + 4b - 25 = 0

In this simplified equation, we can see that it is very similar to the general form of a quadratic equation [ax² + bx + c = 0]

Therefore, we can say that the given equation is Quadratic

Answer:

The dimensions are 7.4m by 15.1 m (to the nearest tenth).

Step-by-step explanation:

Area = length * width

If the width = x then the length = 3x - 7 so

Area x(3x - 7) = 111

3x^2 - 7x - 111 = 0

Using the quadratic formula:

x  = [ -(-7) +/- √((-7)^2 - 4*3*-111)] / (2*3)

x =  7.36, -5.03.

The width must be positive s it is 7.36 m.

The length = 3(7.36) - 7

= 15.08 m.

Answer:

c. 0.55

Step-by-step explanation:

A chosen acre of land is forested and not forested are complimentary event , so let :

F = Chosen land is forested

F = Chosen land is not forested

....and we know  F+F = S

where S is sample space and we know probability ocer whole sample space is 1 , that is P(S)=1 , and we know F and F are independent so

P(F+F) = P(S)

P(F) + P(F)=1

We have given that probability of forest land in randomly chosen an acre land in Canada have probability 0.45 so P(F)=0.45 so ,

0.45 + P(F) = 1

P(F) = 1 - 0.45

P(F) = 0.55

Hence, the probability that the chosen acre is not forested is 0.55
