Answer:

2x+2<-18

Step-by-step explanation:

First subtract 2 from both sides to get 2x<-20

Then divide both sides by 2 to get x<-10

Answer:

Step-by-step explanation:

To get the reasonable range of the situation, we will find the minimum value and maximum value of the calories that can be dressed.

The minimum occur at when x = 0

f(0) = 100(0) +50.

f(0) = 50

Hence the minimum value of the calorie is 50.

The maximum value occur at f'(x)

f'(x)  = 100

Hence the maximum value of the calorie is 100

Hence, the reasonable range for the situation is 50 ≤ x ≤ 100

Step-by-step explanation:

Yes, 6.545454.... is a rational number.

Given that,
To specify that 6.54 repeats a rational number.

Rational numbers are numbers that can be structured in the form of the fraction of integers. Eg- 5/6, 2/3, etc.

An irrational number is a type of real number which cannot be represented as a simple fraction or the values that have face value are irrational numbers. Example: √2, √3, and π are all irrational.

Here,
6.545454...
Above the value 54 posts, the decimal place is repeating, thus the number is rational number.

Thus, Yes, 6.545454.... is a rational number.

The product of two positive numbers is always greater than either number the statement is false.

A numeral system is a way of writing numbers; it's a way of mathematically notating a collection of numbers by utilizing a consistent set of digits or other symbols. In several numeral systems, the same set of symbols may represent various numbers.

Given that the product of two positive numbers is always greater than either number.

To understand this let's take an example take two numbers and multiply them.

2 x 5 = 10

Then take 2 and 0.5 and multiply them.

2 x 0.5 = 1

Here the result of the product is 1 which is less than 2. Therefore, if the product of two positive numbers is always greater than either number the statement is false.

The value of x for the given triangle will be 111°.

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.

The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.

There are many types of triangles such that right-angle triangles, equilateral triangles, and much more.

The sum of all angles inside a triangle is 180°

So,

47° + x° + 22° = 180°

x = 180° - 69° = 111°

Hence "The value of x for the given triangle will be 111°".

Answer:

1. Slope: -0.75x or -3/4x

Y-intercept: 7

Equation: -0.75x+7 or -3/4x-7

Remember -0.75 and -3/4 are the same!

2. Equation: 0.5x-3 or 1/2x-3

I used slope intercept form to solve. (y2-y1 over x2-x1) If you need more help comment below or send me a link!

Answer: (1) -3/4   (2) 7     (3) y = (-3/4)x + 7     (4) 1/2

Step-by-step explanation:

1) COUNT the number of spaces from one point to the other point.

   from (0, 7) to (4, 4) is: down 3 and right 4   →   m = -3/4

2) the y-intercept is where the line crosses the y-axis (when x = 0).

   The line crosses the y-axis at (0, 7)    →   b = 7    

3) Slope-Intercept form is y = mx + b

   m = -3/4  and b = 7     →      y = (-3/4)x + 7

4)  COUNT the number of spaces from one point to the other point.

 from (-2, -4) to (2, -2) is: up 2 and right 4   →   m = 2/4  = 1/2 when simplified

Answer:

sqrt(54) is between 7 and 8

Step-by-step explanation:

Lets look at integers that are squared

1^2  = 1

2^2 = 2

3^2 = 9

4^2 = 16

5^2= 25

6^2 = 36

7^2 = 49

6^2 =64

54- 49 = 5   and 64 - 54 = 10

So 54 is closer to 49

so sqrt(54) is closer to the sqrt(49) = 7

sqrt(54) is between 7 and 8

Arleen has a gift card for a local lawn and garden store. She uses the gift card to . It costs $48 per day to rent the tiller. She also buys a rake for $5.

To Find :

The value on her gift card decreased by how many dollars.

Solution :

Decrease in dollar is given by :

[tex]D =\text{ rent a tiller for 3 days+ price of rake}\\\\D= \$( 48\times 3 + 5)\\\\D = \$149[/tex]

Therefore, the value on her gift card decreased by 149 dollars.

Hence, this is the required solution.
