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.

Answer:

y = -3/4x - 6

Step-by-step explanation:

Use y-intercept (0, -6) and slope -3/4 and put into y=mx+b form to solve for b

Remember that m is also known as slope!

-6=(-3/4 * 0) + b

b= -6

y= -3/4x - 6

Answer:

-3   2   6

Step-by-step explanation:

Consider this expression.

-3x2- 24x - 36

What expression is equivalent to the given expression?

-3 (x + 2)(x+6)

Drop down answer is in bold

The equivalent expression will be :  - 3 (x + 2) (x + 6)

We have the following expression -

[tex]-3x^{2}[/tex] - 24x - 36

We have to find out the equivalent expression of above expression.

Above expression can be expanded in the following way -

(x + 2)(x + 4) = x(x + 2) + 4(x + 4) = [tex]x^{2}[/tex] + 2x + 4x + 16 =   [tex]x^{2}[/tex] + 2x + 16

According to question -

 [tex]-3x^{2}[/tex] - 24x - 36

- 3 ([tex]x^{2}[/tex] + 8x + 12)

-3 ([tex]x^{2}[/tex] + 6x + 2x + 12)

-3 [x(x + 6) + 2(x + 6)]

-3(x + 2)(x + 6)

Hence, the equivalent expression will be :  -3(x + 2)(x + 6)

Answer:

[tex]\boxed {x = 19}[/tex]

Step-by-step explanation:

Solve for the value of [tex]x[/tex]:

[tex]3x - 4 = 15 + 2x[/tex]

-Take [tex]2x[/tex] and subtract it from [tex]3x[/tex]:

[tex]3x - 4 - 2x = 15 + 2x - 2x[/tex]

[tex]x - 4 = 15[/tex]

-Add [tex]4[/tex] to both sides:

[tex]x - 4 + 4 = 15 + 4[/tex]

[tex]\boxed {x = 19}[/tex]

So, the value of [tex]x[/tex] is [tex]19[/tex].

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.

Answer:

If a polygon is a triangle, then it has exactly three sides

Since as have been presented above, the contraposition is true, the original statement must be true

Step-by-step explanation:

The contrapositive statement; If a polygon has more than three sides, then it is not a triangle

We have that the definition of a triangle = A polygon with exactly three sides

Therefore;

A polygon with more than three sides is not a triangle and has (n - 1)/2×180 degrees interior angle, where n = The number of sides

Therefore, when n > 3, (n - 2)/2×180 > 180°

The sum of interior angles of a triangle = 180°

Therefore, the contrapositive statement, if a polygon has more than three sides, then it is not a triangle is true

Therefore, we have;

If a polygon is a triangle, then it has exactly three sides

Since as have been presented above, the contraposition is true, the original statement must be true

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) -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

Step-by-step explanation:

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
