Answer:

-2.1y + 12.9

Step-by-step explanation:

Answer 2

Answer:

12.9-2.1y

Step-by-step explanation:

Use the distributive property to multiply −0.5 by 12y−9.

8.4+3.9y−6y+4.5

Combine 3.9y and −6y to get −2.1y.

8.4−2.1y+4.5

Add 8.4 and 4.5 to get 12.9.

12.9−2.1y

If f(x) = -6x + 1, what is f(1/2x-1) equal to

Answers

9x^2-10x^1+1 from −2x^2+4x−10

By substituting [tex]x = $\frac{1}{2}x-1$[/tex] , the given function f(x) = -6x + 1 can be simplified to [tex]f(x) = $f(\frac{1}{2}x-1) = -3x + 7$[/tex].

To find [tex]$f(\frac{1}{2}x-1)$[/tex], substitute [tex]$\frac{1}{2}x-1$[/tex] into the function f(x):

[tex]$f(\frac{1}{2}x-1) = -6(\frac{1}{2}x-1) + 1$[/tex]

Now, simplify the expression:

[tex]$f(\frac{1}{2}x-1) = -3x + 6 + 1$\\\\$f(\frac{1}{2}x-1) = -3x + 7$[/tex]

So, [tex]$f(\frac{1}{2}x-1) = -3x + 7$[/tex].

Answers

6.39 :) because in the tenths place there is a 3 and the six rounds that up to a 4!

Answer:

Step-by-step explanation:

4.04 rounded will be just 4

5.39 rounded is 5.4

6.34 rounded is 6.3

7.48 rounded is 7.5

When rounding if the second number is less than 4 you don't change it like in 6.34 that 4 after the 3 means it will just be 6.3 BUT if the second number is 5 or higher you round up on like with 5.39 it became 5.4 and with 7.48 it became 7.5

Suppose a bank charges a base rate of $5 plus $0.10 per check for your checking account. You can switch to a different account that charges $4 plus $0.20 per check. For what number of checks is the monthly cost of the two accounts the same? What is the cost?

Answers

Answer:

10 number of checks.

Cost = $6

Step-by-step explanation:

Given that:

Fixed Charges of first bank = $5

Charges of first bank per check = $0.10

Fixed Charges of second bank = $4

Charges of second bank per check = $0.20

To find:

Number of checks such that the charges for the banks become the same?

Solution:

Let the number of checks = [tex]x[/tex]

Cost for the first bank for [tex]x[/tex] checks = $5 + $0.10[tex]x[/tex]

Cost for the second bank for [tex]x[/tex] checks = $4 + $0.20[tex]x[/tex]

As per question statement, both the costs are the same.

Comparing the values:

[tex]5 + 0.10x = 4 + 0.20x\\\Rightarrow 0.10x = 1\\\Rightarrow x = 10[/tex]

So, for 10 number of checks the cost will be same.

The cost = 4 + 0.20 [tex]\times[/tex] 10 = $6

The percentage profit earned by selling a watch for Nu 1920 is equal to the percent loss incurred by selling the same watch for Nu 1280. At what price should the watch be sold to make 25% profit

Answers

Answer:

2,000

Step-by-step explanation:

The computation of the price that should be sold for making 25% profit is shown below:

Let cost price be x

Now the equation would be

(1,920 - x) ÷ x × 100 = (x - 1,280) ÷ x × 100

1,920 - x = x - 1,280

2x = 3,200

x = 1,600

Now the sale price would be

= 1,600 × 1.25

= 2,000

there are 5 people in Edgar's family. they have 3 loaves of pumpkin bread to share equally. Edgar wants to know how much pumpkin bread he will get?

Answers

Answer:

3 divided 5

Step-by-step explanation:

Edgar will get 3/5 or 0.6 part of pumpkin bread.

What is ratio?

Ratio basically compares quantities, that means it show value of one quantity with respect to other quantity.

If a and b are two values, their ratio will be a:b,

Given that,

Total numbers of people in Edgar's family = 5

Total number of pumpkin bread = 3

Since, 3 bread are divided equally among 5 people,

implies that, bread will divide in the same ratio,

5 people = 3 bread

1 people= 3/5 bread

1 people= 0.6 part of bread

So Edgar will get 3/5 or 0.6 part of bread.

Michael borrowed $1000 on a 2 year loan. He is charged 5% simple interest per year.
How much interest is he charged for 2 year? What is the total amount he has to pay
back?

O $10, $1010
O $50, $5000
O $100, $1100

Answers

Answer:

the last choice

Step-by-step explanation:

simple interest means there is only interest on the original principal (1000$)

so 2 years of 5% would be 10%, 10% of 1000 is 100.

total amount = interest+principal, so it is 100, 1100

How is the earthworm limited by being a skin breather? What type of philosopher was Plato?realisticidealisticindividualisticpessimistic Read the passages:Passage A Minerals, water, air, organic matter, and organisms make up the material we call soil. This material covers the Earth's surface and supports life. Without soil, plants would not grow, and animals would not survive.Even though speaking about soil seems simple enough, it is actually very complex. That is because soil comes in many different forms which are made of layers, called horizons. When you look at the horizons together, you get a soil profile. Each horizon has its own set of characteristics. Some soil characteristics are the amount of sand, the type of minerals, and the amount of decomposing leaves found in the soil. All of these characteristics will help determine what kind of plant life the soil can support.Passage B Healthy plants are plants that are able to take sunlight, water, and nutrients and turn them into food. Their roots absorb two of these ingredients from the soil around them. The ideal soil for growing is one that contains the right amount of water without being too wet. It also contains many nutrients.How do nutrients make it into the soil? The answer is actually quite complex. Nutrient-rich soil contains organic matter, which is broken-down plant and animal matter. As the plant and animal matter decays, or decomposes, it releases nutrients into the soil. Then, it is absorbed by living plants and turned into food. Therefore, the richer the nutrients in the soil, the healthier the plant.Based on the information in Passages A and B, how do the nutrients in the soil determine what kind of plant it can support? In order to get nutrients into the soil, plants and animals decompose, which means they are broken down and absorbed as food. Plants absorb the nutrients they need from the soil to make food, so the type of nutrients in the soil need to match the type of nutrients needed by the plant. Soil horizons share their nutrients so that plants and animals have enough food to survive, especially during the summer season. The minerals, water, and organic matter in the soil keep plants from growing large, so plants need to choose a spot that doesn't have any of those things. when did the black death begin Choose the graph of this equation. y = 2.5xBRAINLIST IF RIGHT!!!!
