Please help iv added a pic of the work sheet. I have to get this done by tomorrow

Answers

You do this by moving all terms without y to the right hand side, and then divide the whole lot to keep a clean y= on the left hand side.

Moving to the other side is done by subtracting (or adding) a term from both sides. Effectively this looks like you're moving the term and flipping the sign.

So 2y + 18 = 4x changes into 2y +18 -18 = 4x -18 so 2y = 4x - 18. If you forget about the middle step, it looks like the +18 jumped to the other side and changed sign. That's all.

Second step is to change the 2y into y. You do that by dividing everything by 2. So 2y=4x-18 becomes y=2x-9

1. y=2x-9
2. y=3/2x - 6
3. y=4x+18
4. y=2x-12

5. y=-4x+18
6. y=2/3x+4
7. y=-1/4x-18/4
8. y=1/4x-18/4

9. y=1/4x+18/4
10. y=-1/4x+18/4
11. y=-3/2x+6
12. y=3/2x+6

13. y=-3/2x-6
14. y=-2/3x-4
15. y=2/3x+2/3
16. y=18-4x

What is the relationship between 8.76×106 and 8.76×102 ? Select from the drop-down menus to correctly complete the statement. 8.76×106 is times than 8.76×102 .

Answers

8.76 x 10^6 is 10,000 times greater than 8.76 x 10^2.

Answer:

[tex]8.76\times 10^6[/tex] is 10,000 times [tex]8.76\times 10^2[/tex].

Step-by-step explanation:

Let [tex]8.76\times 10^6[/tex] be n times [tex]8.76\times 10^2[/tex].

We have been given two numbers [tex]8.76\times 10^6[/tex] and [tex]8.76\times 10^2[/tex].

We can represent this information in an equation as:

[tex]8.76\times 10^2\cdot n=8.76\times 10^6[/tex].

[tex]\frac{8.76\times 10^2\cdot n}{8.76\times 10^2}=\frac{8.76\times 10^6}{8.76\times 10^2}[/tex]

[tex]n=\frac{8.76\times 10^6}{8.76\times 10^2}[/tex]

Using exponent property of fractions [tex]\frac{a^m}{a^n}=a^{m-n}[/tex], we will get:

[tex]n=\frac{8.76\times 10^{6-2}}{8.76}[/tex]

[tex]n=1\times 10^{4}[/tex]

[tex]n=10,000[/tex]

Therefore, [tex]8.76\times 10^6[/tex] is 10,000 times [tex]8.76\times 10^2[/tex].

A sack full of medals contains gold, silver, and bronze. If selected at random, the probability of picking a gold medal is 5/12. The probability of picking a silver medal is 1/3. What is the probability of picking a bronze medal? Express the probability as a number between 0 and 1.

Answers

Final answer:

The probability of picking a bronze medal is found by subtracting the probabilities of picking a gold and a silver medal from 1. As the probability of picking gold is 5/12 and silver is 1/3 (or 4/12), the probability of picking bronze is 1 - (5/12 + 4/12) = 1/4 or 0.25.

Explanation:

The probability of picking each type of medal from the sack adds up to 1 since one of the medals must be picked. Given the probability of picking a gold medal is 5/12 and the probability of picking a silver medal is 1/3, we can calculate the probability of picking a bronze medal by subtracting the probabilities of picking a gold or silver medal from 1.

First, let's find a common denominator for 5/12 and 1/3, which is 12. The probability of picking a silver medal expressed with the denominator 12 is 4/12 (since 1/3 equals 4/12).

Now, we add the probabilities of picking a gold or silver medal: 5/12 + 4/12 = 9/12.

Finally, we subtract this sum from 1 to find the probability of picking a bronze medal:
1 - 9/12 = 3/12, which simplifies to 1/4.

Therefore, the probability of picking a bronze medal is 1/4, or 0.25 when expressed as a number between 0 and 1.

5.34 x 10^5 is 10,000,000 times greater/less than 5.34 x 10^-2
5.34 x 10^5 = 10,000,000 and 5.34 x 10^-2 = 0.0534 thus c: is your answer.

Answers

Subtracting b from both sides, we get y-b=mx. Next, we can divide x from both sides to get (y-b)/x=m. This does not fit into any option, however, as y-b/x is different from (y-b)/x due to that in the former, you first do b/x while in the latter you have to subtract b from y first

The cost to rent a car is $30 per day. Write an expression for the cost of renting a car d days. Make a table to find how much it will cost to rent a car for 3, 5, 7, and 10 days.

Answers

d = day
c = cost

c = 30d

Day(d) | c = 30d    | Cost(c)
3 | 90=30(3)   | $90
5 | 150=30(5)   | $150
7    | 210=30(7) | $210
10    | 300=30(10)  | $300

Answer:The expression for the cost of renting a car d days is:

[tex]c=30d[/tex]

The table can be made as follows:

Number of days Cost

3 90

5 150

7 210

10 300

Step-by-step explanation:

It is given that:

The cost to rent a car is $30 per day.

Now, the expression which is used to represent the cost for renting a car d days is:

[tex]c=30d[/tex]

where c is the cost of renting a car.

when d=3 we have:

c=90

( Since, 30×3=90 )

when d=5

c=150

( Since, 30×5=150 )

when d=7

c=210

( Since, 30×7=210 )

when d=10

c=300

( Since, 30×10=300 )

There are 300 apples and peaches for sale at a farmer's market. The ratio of the number of apples to the number of peaches is 7 : 8. If 50 apples and 40 peaches are sold, what is the ratio of the remaining apples to peaches?

4.3t-2.1t-2.3=7.6
Solve equation

Answers

If your solving for t then t = 4.5

Final answer:

The equation can be solved by combining like terms, isolating the variable t, then dividing by the coefficient of the variable. The solution to the equation is t = 4.5.

Explanation:

The given equation in this problem is 4.3t - 2.1t - 2.3 = 7.6. To solve the equation, first we need to combine like terms, meaning we would subtract 2.1t from 4.3t.

This leaves us with 2.2t - 2.3 = 7.6. After that, we must isolate t by adding 2.3 to both sides of the equation. This results in 2.2t = 9.9. Finally, we divide both sides by 2.2 to solve for t, which gives us t = 4.5.

How many subsets of the set m,a,t,h,c,o,u,r,s,e contain at least one vowel

Answers

Final answer:

The given set contains 10 elements. Subsets with at least one vowel can be found by considering different combinations of vowels in the set which is 3 + 3 + 0 = 6.

Explanation:

The given set m,a,t,h,c,o,u,r,s,e contains 10 elements.

In order to find the number of subsets that contain at least one vowel, we need to consider the possible combinations of vowels in the set.

If we consider only one vowel, there are 3 vowels in the set (a, o, and u). Therefore, there are 3 choose 1 = 3 subsets.If we consider two vowels, there are 3 choose 2 = 3 subsets.If we consider three vowels, there is 1 choose 3 = 0 subset (as there is only 1 vowel left).

Therefore, the total number of subsets that contain at least one vowel is 3 + 3 + 0 = 6.

Final answer:

To find the number of subsets of the set m,a,t,h,c,o,u,r,s,e that contain at least one vowel, we can count the number of subsets that have no vowels and subtract it from the total number of subsets.

Explanation:

To find the number of subsets of the set m,a,t,h,c,o,u,r,s,e that contain at least one vowel, we can count the number of subsets that have no vowels and subtract it from the total number of subsets. The given set contains 9 consonants and 5 vowels. So, the number of subsets with no vowels is equal to the number of subsets of the 9 consonants, which is 2^9 = 512.

The total number of subsets of the given set is 2^14 = 16384. Therefore, the number of subsets that contain at least one vowel is 16384 - 512 = 15872.

A group of students and teachers are going on a field trip? One ninth of the group will fit on 1/3 of a school bus. How many buses are needed to transport the entire group?

Answers

3/9 will fit on one bus so it will take 3 buses to fit 9/9 of the students, which 9/9 is the whole group.

The entire group will need 3 buses to transport them on the field trip.

How many buses will be needed?

Let total number of people in the group be represented by 'P'

We are told that 1/9 of the group can fit on 1/3 of a school bus.

So, this shows 1/9 of P = (1/3) of a bus; we will write an equation to find the total number of buses needed

==>

(1/9)P = (1/3) bus

P = (1/3) bus * 9

P = 9/3

P = 3 buses.
