X=89.4

Step-by-step explanation:

The graph that represents the solution to this inequality is x > -1.

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal =

Greater than and equal=

We have,

The given inequality is 16x - 80x < 37 + 27.

Simplifying the left-hand side of the inequality.

-64x < 64

Dividing both sides by -64

(remember to reverse the inequality because we're dividing by a negative number).

x > -1

Now,

This inequality represents all values of x that are greater than -1.

To represent this solution graphically, we would shade the region to the right of the vertical line x = -1, as all x values to the right of -1 satisfy the inequality.

Thus,

The graph that represents the solution to this inequality is x > -1.

After deducting Linda's $1,000 deductible and 20% coinsurance from her total medical bills, the insurance company paid $4,360 for the year.

Linda's health insurance policy has a deductible of $1,000, meaning that amount will have to be paid out of her pocket before the insurance starts to cover. In addition, the policy has 20% coinsurance, which means Linda is responsible for 20% of the remaining healthcare costs after the deductible is met.

First, calculate the bills Linda has to pay after the deductible: $6450 - $1000 = $5450.

Next, account for the coinsurance by calculating 20% of that amount: 0.20 * $5450 = $1090.

To find out how much the insurance company paid, we subtract the amount Linda pays from her total bills. Therefore, $6450 - $1000 (deductible) - $1090 (coinsurance) = $4360. So, the insurance company paid $4360 for the year.

Brady bought items totaling $42.13 from the hardware store. After giving a hundred-dollar bill, he received $57.87 in change.

To calculate the change Brady gets back from the hardware store, we need to add up the cost of the items he purchased and then subtract this total from the amount of the hundred-dollar bill he provided to the owner. First, we add the cost of the wrench ($9.63), the nail gun ($28.01), and the dozen nails ($4.49) to find the total spending. Once we have the total, we subtract it from $100 to find out how much change Brady should receive.

Answer:

f(x)=(x+2)(x−(−1+i2√))(x−(−1−i2√))

Sorry if its wrong!

The required completely factored form is f(x) = (x + 2)(x−(−1+i2√))(x−(−1−i2√)).

Factorization, also known as factoring, is the breakdown of one element into a product of other objects, or factors, which when multiplied together generate the original. For example, the number 21 factors into primes as 3 × 7, and the polynomial x² − 9 factors as (x+3)(x-3).

The function is given in the question following as:

f(x) = x³ + 4x² + 7x + 6

We have to determine the completely factored form of the given function

As per the given question, we have

⇒ f(x) = x³ + 4x² + 7x + 6

Common factor as (x + 2) out in the above expression,

⇒ f(x) = (x + 2)(x² + 2x + 3)

⇒ f(x) = (x + 2)(x−(−1+i√2))(x−(−1−i√2))

Therefore, the required completely factored form is f(x) = (x + 2)(x−(−1+i2√))(x−(−1−i2√)).

Carmen often orders party trays from her favorite Mexican food restaurant For company events. For a recent company party, she spent $58 on one burrito platter and one taco platter. For a company meeting, she spent $90 on two burrito platters and one taco platter. How much does each type of platter cost?

The cost of each buritto platters is $ 32 and cost of each taco platter is $ 26

Let "a" be the cost of each burrito platters

Let "b" be the cost of each taco platters

Carmen spent $58 on one burrito bladder and one taco platter

Therefore we frame a equation as:

one burrito bladder x cost of each burrito platters + one taco platter x cost of each taco platters = 58

[tex]1 \times a + 1 \times b = 58[/tex]

a + b = 58 ---------- eqn 1

For a company meeting, she spent $90 on two burrito platters and one taco platter

two burrito platters x cost of 1 burrito platter + one taco platter x cost of 1 taco platter = 90

[tex]2 \times a + 1 \times b = 90[/tex]

2a + b = 90 ----------- eqn 2

Let us solve eqn 1 and eqn 2

Subtract eqn 1 from eqn 2

2a + b -a - b = 90 - 58

a = 32

Substitute a = 32 in eqn 1

32 + b = 58

b = 26

Hence, cost of 1 burrito = $32  and the cost of 1 taco platter = $26

To learn more on augmented matrices, we kindly invite to check this verified question: https://brainly.com/question/4945755

Final answer:

To solve the system of equations, we need to find the reduced row-echelon form of the augmented matrix. Applying row operations, we can reduce the matrix to row-echelon form. Then, using backward substitution, we can find the values of x, y, and z. The solution to the system of equations is (-10, 2, 8.5).

Explanation:

To solve the system of equations, we can represent it as an augmented matrix and find its reduced row-echelon form. The augmented matrix for the given system of equations is:

[2 1 4 | 16]
[5 -2 2 | -1]
[1 2 -3 | -9]

Next, we need to apply row operations to reduce the matrix to its row-echelon form. Following the Gaussian elimination method, we perform the row operations:

R2 → R2 - 5R1, and
R3 → R3 - R1

The resulting matrix in row-echelon form is:

[2 1 4 | 16]
[0 -7 -18 | -81]
[0 0 0 | 0]

Now, we can apply backward substitution to find the values of x, y, and z. From the last row of the row-echelon form, we know that 0z=0. We can assign any value to z, such as 1, and then solve for x and y. Plugging in z=1, we get:

2x + 1y + 4(1) = 16

x + 2y - 3(1) = -9

Simplifying these equations, we get:

2x + y + 4 = 16 → 2x + y = 16 - 4 → 2x + y = 12

x + 2y - 3 = -9 → x + 2y = -9 + 3 → x + 2y = -6

Using these equations, we can solve for x and y by setting up a system of linear equations:

2x + y = 12
x + 2y = -6

Solving this system, we can find the values of x and y: x = -10 and y = 2. Finally, substituting these values back into one of the original equations, we can find z:

2(-10) + 1(2) + 4z = 16 → -20 + 2 + 4z = 16 → 4z = 34 → z = 8.5

So, the solution to the system of equations is (-10, 2, 8.5).

3x = 270

x = 270/3

x = 90 m

Breadth = 90m = 90 *100 = 9000 cm

Length = 2*90 = 180 m = 180 * 100 = 18000 cm

The correct answer is The graph stretches because 7 is bigger than 1.

The graph of [tex]\( f(x) = 7|x-5|+9 \)[/tex] experiences a vertical stretch, not a shrink, despite the coefficient ( 7 ) being greater than 1.

The absolute value function ( |x| ) reflects any negative values of ( x ) to their positive counterparts, essentially mirroring the negative portion of the graph onto the positive side.

When you apply a coefficient greater than 1 to [tex]\( |x| \), as in \( 7|x| \),[/tex] it vertically stretches the graph.

This means that the graph of ( f(x) ) will be vertically stretched by a factor of 7 compared to the graph of ( |x| ).

In this case, since [tex]\( |x-5| \)[/tex] is the argument of the absolute value, it implies a horizontal shift of the graph of [tex]\( |x| \)[/tex] by 5 units to the right.

So, the absolute value graph [tex]\( |x| \)[/tex] gets shifted 5 units to the right before it is stretched vertically by a factor of 7.

The ( +9 ) at the end of the function only moves the entire graph up by 9 units.

Thus, the graph of [tex]\( f(x) = 7|x-5|+9 \)[/tex] experiences a vertical stretch by a factor of 7.

Therefore, the correct statement is: "The graph stretches because 7 is bigger than 1."

Question

Does the absolute value graph below stretch or shrink? Support your answer. F(x) = 7|x-5|+9

The graph shrinks because 7 is between 0 and 1.

The graph stretches because 7 is bigger than 1.

The graph shrinks because 7 is bigger than 1.

Answer:

Explanation:

First, you must find the y-value returned by the line in the graph for a time (x) of five minutes, and then use the deviation of 3º to conclude the range of the real temperature.

1. y- value at x = 5 min.

The trend line (blue line in the graph) passes through the point (5,15), which means that it predicts a temperature of 15ºF when the time (x) is 5 minutes, or five minutes after the freezer was turned on.

2. Actual temperature value

It is stated that the temperature was actually three degrees from what the trend line shows, that means that the actual temperature could be 3ºF more or 3ºF less than the predicted temperature of 15ºF.

Mathematically:

The values that the actual temperature could be after the freezer was on for five minutes are 12°F or 18°F.

A trendline is sometimes referred to as a line of best fit and it is a statistical tool which is commonly used in conjunction with a scatter plot, in order to determine whether or not there's any form of correlation (either positive or negative) between a given data.

By critically observing the scatter plot, we can logically deduce that the trend line passes through the point (5, 15), which implies that the temperature is 15°F, 5 minutes after the freezer was turned on.

Since the actual temperature deviates by 3°F from what the trend line shows, we have:

Actual temperature = 15 ± 3

Actual temperature = 15 - 3 = 12°F

Actual temperature = 15 + 3 = 18°F

Answer:

45 m - 30   ≥  275 x (4)  is the required inequality.

Step-by-step explanation:

m: The number of lawns they need  to mow next week

The charge per mowing of lawn = $45

The total earnings spent on gasoline each week  = $30

The earning per person is AT LEAST $275.

Now,if 1 person earns at least $275

So, the total minimum earnings of 4 people  = 4 x ($275)  = $ 1100

Also, of per mow charge  = $45

So, the charge of mowing m lawns  = m x ( Per mow charge )  

= m x ( $45) = 45 m

Now, according to question:

Total Earning - Money spent on gasoline  ≥  Total Earning $1100  

or, 45 m - 30   ≥   1100

Hence, the needed inequality is  45 m - 30   ≥   1100

or, 45 m - 30   ≥  275 x (4)
