Step-by-step explanation:

Using the rules of exponents

[tex]a^{m}[/tex] × [tex]a^{n}[/tex] ⇔ [tex]a^{(m+n)}[/tex]

[tex](a^m)^{n}[/tex] = [tex]a^{mn}[/tex]

[tex]a^{-m}[/tex] ⇔ [tex]\frac{1}{a^{m} }[/tex]

Thus

[tex]4^{3x-2}[/tex]

= [tex]4^{3x}[/tex] × [tex]4^{-2}[/tex]

= [tex](4^3)^{x}[/tex] × [tex]4^{-2}[/tex]

= [tex]64^{x}[/tex] × [tex]\frac{1}{4^2}[/tex]

The equation that modeled the graph is -x + 1 = 2x + 3.

The correct option is A.

A pair of algebraic equations with the equal symbol (=) in the center and the same value is referred to as an equation.

As per the information provided, it is given one red rectangular box with '-x' and one small yellow square box with '1' equals 2 green rectangular boxes and 3 yellow square boxes.

The equation in numeric form can be described as:

-1x + 1 = 2g + 3

where:

-1x represents the red rectangular box with '-x'

1 represents the small yellow square box with '1'

2g represents the two green rectangular boxes

3 represents the three yellow square boxes.

Therefore, the equation is -x + 1 = 2x + 3.

The answer is below

Step-by-step explanation:

Hana has some blue paint. She wants to lighten the shade, so she mixes in 1  cup of white paint. The color is still too dark, so Hana keeps mixing in 1 cup of  white paint at a time. After adding 4 cups, she decides the color is too light.

How would she express the amount of paint to add to be between too dark and too light.

Solution:

After adding a cup of white paint, the color is still dark, she adds the second cup of paint and the color is still dark. She adds the third cup of paint and the color is still dark but when she adds the fourth cup of white paint, the color became too light.

This means that the amount of paint to add to be between too dark and too light is between the third and fourth cup.

Let w represent the amount of paint to add to be between too dark and too light. Hence:

3 < w < 4

Answer:

the y-intercept is 8 and the slope is -4/3 .

Step-by-step explanation:

The y - intercept is (0, 8) and the slope is -4/3

"It is the point at which the graph of the function intersects the y-axis"

The slope of the line passing through points [tex](x_1,y_1),(x_2,y_2)[/tex] is,

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

For given example,

We can observe that the line of best fit on this scatter plot passes though points (0, 8) and (6, 0)

Using the slope formula,

⇒ slope = (0 - 8)/(6 - 0)

⇒ slope = (-8)/6

⇒ slope = -4/3

Also, we can observe that the line of best fit on this scatter plot intersects y-axis at point (0, 8)

So, the y - intercept is (0, 8)

Therefore, the y - intercept is (0, 8) and the slope is -4/3

Step-by-step explanation:

The amount of money that he spent on his hamster round to the nearest dollar will be $43.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

Maurice has a pet hamster. In October he burned through $13.68 on hamster food $7.89 on wood shavings and $21.14 on another hamster wheel.

Then the amount of money that he spent on his hamster will be given by the summation of $13.68, $7.89, and $21.14.

⇒ $13.68 + $7.89 + $21.14

⇒ $42.71

⇒ $43

The amount of money that he spent on his hamster round to the nearest dollar will be $43.

Answer:

  38.5°

Step-by-step explanation:

A triangle solver can give an answer easily. The angle is 38.5°.

__

The law of cosines can be written to solve for an unknown angle C opposite side 'c' and flanked by sides 'a' and 'b'.

  C = arccos((a² +b² -c²)/(2ab))

Here, we have a=35, b=48, c=30, so the angle is ...

  C = arccos((35² +48² -30²)/(2·35·48)) = arccos(2629/3360) ≈ 38.515°

The angle the cable makes with the pole is about 38.5°.

Answer:

D. 353

Step-by-step explanation:

just took test

The approximate direction angle of v =<8, -1> is 353°

For any vector its direction angle is the angle that vector makes with a horizontal line.

The direction angle of vector <x , y> is ,

[tex]\theta=tan^{-1}(\frac{y}{x} )[/tex]

For given example,

We have been given a vector v = <8, -1>

Let [tex]\theta[/tex] be the direction angle

x = 8, y = -1

Using the formula of direction angle of vector,

[tex]\Rightarrow \theta=tan^{-1}(\frac{y}{x} )\\\\\Rightarrow \theta=tan^{-1}(\frac{-1}{8} )\\\\\Rightarrow \theta=tan^{-1}(-0.125)\\\\\Rightarrow \theta=-7.12501635\\\\\Rightarrow \theta \approx -7^{\circ}[/tex]

If we measure this angle in anticlockwise direction then the direction angle would be,

[tex]\Rightarrow \theta=360^{\circ}-7^{\circ}\\\\\Rightarrow \theta=353^{\circ}[/tex]

Therefore, the approximate direction angle of v is 353°

Answer: Good luck guys

a) 4(9 x - 18)  > 3(8x  + 12)

The solution to the inequality is x > 9.

Graph A.

b) -1/3 (12x + 6) ≥ -2x + 14

The solution to the inequality is x ≥ -8.

Graph B.

c) 1.6 (x + 8) ≥ 36.4

The solution to the inequality is x ≥ 14.75.

Graph C.

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,

a)

4(9x - 18) > 3(8x + 12)

First, we can simplify both sides of the inequality:

36x - 72 > 24x + 36

Next, we can isolate the variable on one side by subtracting 24x from both sides:

12x - 72 > 36

Finally, we can isolate x by adding 72 to both sides:

12x > 108

x > 9

Therefore, the solution to the inequality is x > 9.

b)

-1/3(12x + 6) ≥ -2x + 14

First, we can simplify the left-hand side of the inequality:

-4x - 2 ≥ -2x + 14

Next, we can isolate the variable on one side by adding 4x to both sides:

-2 ≥ 2x + 14

Then, we can isolate x by subtracting 14 from both sides:

-16 ≥ 2x

Finally, we can divide both sides by 2, remembering to reverse the direction of the inequality because we are dividing by a negative number:

-8 ≤ x

Therefore, the solution to the inequality is x ≥ -8.

c)

1.6(x + 8) ≥ 36.4

First, we can simplify the left-hand side of the inequality:

1.6x + 12.8 ≥ 36.4

Next, we can isolate the variable on one side by subtracting 12.8 from both sides:

1.6x ≥ 23.6

Finally, we can divide both sides by 1.6:

x ≥ 14.75

Therefore, the solution to the inequality is x ≥ 14.75.

Thus,

a) 4(9 x - 18)  > 3(8x  + 12)

The solution to the inequality is x > 9.

Graph A.

b) -1/3 (12x + 6) ≥ -2x + 14

The solution to the inequality is x ≥ -8.

Graph B.

c) 1.6 (x + 8) ≥ 36.4

The solution to the inequality is x ≥ 14.75.
