The solution to this inequality in interval notation is {-∞, -3} and it goes to the left on the number line.

In Mathematics, an inequality can be defined as a mathematical relation that is typically used for comparing two (2) or more numerical data such as integers, and variables in an equation based on any of the following inequality symbols:

From the information provided, we have the following inequality:

4.2y ≤ -12.6

Dividing both sides of the inequality by 4.2, we have the following:

y ≤ -12.6/4.2

y ≤ -3

In conclusion, a solution to this inequality is equal to {-∞, -3} as shown in the number line (graph) attached below.

The expression 2(3+4) can be expressed as 2×7

A factor is a number that divides another number, leaving no remainder. In other words, if multiplying two whole numbers gives us a product, then the numbers we are multiplying are factors of the product because they are divisible by the product.

For example the factors of 8 are 1,2,4,8. i.e 1×8=8, 2×4= 8

considering the expression 2(3+4), the value is 2(7)= 14

Therefore the expression can be expressed as product of two factors (2 and 7) as 2×7.

Answer:

slope is m=1

Step-by-step explanation:

Answer: 1

Step-by-step explanation: use the slope formula to find the slope m

The value of a and b in the function  f(x) = √ x+2 and g(x) = ax + b , is a = 0 and b = 2  .

In the question ,

it is given that ,

the function f(x) = √(x+2) and the function g(x) = ax + b

also given that

fog(1) = 2

f(g(1)) = 2

f(a + b) = 2         .... because g(1) = a + b

√(a + b +2) = 2

Squaring both the sides

a + b + 2 = 4

a + b = 2      .......(1)

also given that

g(-1) = 2

a(-1) + b = 2

-a + b = 2         .....(2)

Adding equation (1) and (2) , we get

2b = 4

b = 2

Substituting b = 2 in the a + b = 2 , we get

a + 2 = 2

a = 2 - 2

a = 0

Therefore , The value of a and b in the function  f(x) = √ x+2 and g(x) = ax + b , is a = 0 and b = 2  .

Step-by-step explanation:

The maximum that the company can expect for returned items is C. $5972.65

How to calculate the value?

From the information, the average daily profit of an electronics store is $31,435 and the company estimates that 15% is lost each day to returns, with a margin of error of ±4%.

In a random survey sample, a margin of error is a statistical measurement that takes into account the discrepancy between actual and anticipated findings. Simply said, you may determine the degree of unpredictability in data and research results using the margin of error.

The maximum the company can expect for returned items will be:

= (15% + 4%) × Profit

= 19% × $31,435

= 0.19 × $31,435

= $5972.65

Answer:

y + 4 = -(x - 8)

Step-by-step explanation:

The point-slope form equation is y - y1 = m(x - x1)

Since we're given m and since they use the 4 from (8, -4) as y - (-4) = y+4, we simply need to plug in 8 into the RHS of the equation and you can check the math.

If you substitute 8 and -4 for y and x, you have:

-4 + 4 = -1(8 - 8)

0 = -1 * 0

0 = 0

You'd get -2 on both sides if you used -6 and 10, but having an equal equation means our math is true/accurate.

Step-by-step explanation: 3.5 x 7 = 24.5

Answer: 24.5 ounces

Step-by-step explanation:

3.5 times 7 = 24.5 ounces

If you have trouble try

3.5 + 3.5 + 3.5 + 3.5 + 3.5 + 3.5 + 3.5

Since we are give the area, the length, and the width, we could put it in a formula.

2592=(16)(12)h

Multiply 16 x 12= 192

So now the formula is 2592= 192h

lastly, we divide 192 from 2592

1. An equation representing the number of days Amir has been reading and the number of pages he has read is y = 35x.

2. An equation representing the number of days Jesse has been reading and the number of pages she has read is y = 30 + 30x.

3. The system of equations from 1 and 2 is y = 35x and y = 30 + 30x.

4. At the end of Friday, after solving the equations, both Jesse and Amir read 210 pages each, with Jesse spending 7 days and Amir 6 days.

5. For Jesse and Amir, the equation solutions are y is 210 pages and x is 6 days.

6. After solving the equations, it will take Amir 6 days to catch up with Jesse and each person must have read 210 pages or a total of 420 pages.

A system of equations involves using more than one equation solved simultaneously.

Jesse's reading rate per day = 30 pages

Amir's reading rate per day = 35 pages

The number of pages read by Jesse, y = 30 + 30x

The number of pages read by Amir, y = 35x

Where x = the number of days they have been reading

y = 30 + 30x and y = 35x

35x  = 30 + 30x

35x - 30x = 30

5x = 30

x = 6 (30/5)

y = 30 + 30x

y = 30 + 30(6)

y = 210

y = 35x

y = 35(6)

y = 210

The number of each type of stamp used is as follows:

Melinda needed to mail a package. She used .02 stamps and .10 stamps to mail the package. She used 15 stamps worth 0.78. The number of each type of stamp she used can be calculated as follows:

let

x = number of 0.02 stamp

y = number of 0.10 stamp

Using system of equation,

x + y = 15

0.02x + 0.10y = 0.78

multiply equation(ii) by 50

x + y = 15

x + 5y = 39

4y = 24

y = 24 / 4

y = 6

Hence,

x = 15 - 6

x = 9

Therefore, the number of 0.02 stamps is 9 and the number of 0.10 stamp is 6.
