Step-by-step explanation:

Hello.

You would write the equation like this: [tex]\frac{2}{3} c - 2[/tex]

Let me know if that was what you were looking for.

Answer:

Step-by-step explanation:

(a) In order to use the elimination method, multiply the second equation by 2.

It becomes 2x + 4y = 20.

Subtract that from the first equation: 3x + 4y = 12

3x + 4y - 2x - 4y = 12 - 20

x = -8

Put that back in the second equation: -8 + 2y = 10

2y = 18

y = 9

(b) In order to use the substitution method, subtract 2y from the second equation.

It becomes x + 2y - 2y = 10 - 2y

x = 10 - 2y

Substitute that into the first equation:

3(10 - 2y) + 4y = 12

30 - 6y + 4y = 12

30 - 2y = 12

2y = 18

y = 9

Put back into the equation for x:

x = 10 - 2(9)

= 10 - 18

= -8

Answer:

Step-by-step explanation:

(1) 3x + 4y = 12

(2) x + 2y = 10

(2)*3: 3x+6y=30

by elimination (2)*3 - (1)

6y-4y=30-12

2y=18

y=9

x+2(9)=10

x=-8

rearrange (2): x=10-2y

substitute in (1): 3(10-2y)+4y=12

30-6y+4y=12

2y=30-12

y=9

x=10-2(9)

=-8

Step-by-step explanation:

The area of a rectangle can be calculated with the formula:

[tex]A=lw[/tex]

l: the length of the rectangle.

w: the width of the rectangle.

The area of the remaning wall after the mural has been painted, will be the difference of the area of the wall and the area of the mural.

Knowing that the dimensions of the wall are [tex](6x+7)[/tex] by [tex](8x+5)[/tex], its area is:

[tex]A_w=(6x+7)(8x+5)\\\\A_w=48x^2+30x+56x+35\\\\A_w=48x^2+86x+35[/tex]

As they are planning that the dimensions of the mural be [tex](x+4)[/tex] by [tex](2x+5)[/tex], its area is:

[tex]A_m=(x+4)(2x+5)\\\\A_m=2x^2+5x+8x+20\\\\A_m=2x^2+13x+20[/tex]

Then the area of the remaining wall after the mural has been painted is:

[tex]A_{(remaining)}=A_w-A_m\\\\A_{(remaining)}=48x^2+86x+35-(2x^2+13x+20)\\\\A_{(remaining)}=48x^2+86x+35-2x^2-13x-20\\\\A_{(remaining)}=46x^2+73x+15[/tex]

Step-by-step explanation:

Answer:

The answer is C because when you substituted the coordinate pairs into the equation, both sides are equal which tells you that they're a solution to the equation.

Explanation:

All you do is substitute. (x,y)

A:

Substitute

1 = 4(2) - 7

Multiply the number inside the parentheses by the outside number.

1 = 8 - 7

Subtract to get your solution.

1 = 1

Both sides equal to each other so this means that this is a solution to the equation.

B:

Substitute

9 = 4(4) - 7

Multiply the number inside the parentheses by the outside number.

9 = 16 - 7

Subtract to get your solution.

9 = 9

Both sides equal to each other so this means that this is also a solution to the equation.

D:

Both ordered pair is a solution to the equation.

Answer:

9.4 units

Step-by-step explanation:

To find the distance between two points D ( 1, 3 ) and H ( 9, 8 ), we can use the distance formula:

d = √(( x₂ - x₁ )² + ( y₂ - y₁ )² )

Substituting the coordinates, we have:

d = √( ( 9 - 1 )² + ( 8 - 3 )²)

Simplifying,

d = √( 8² + 5² )

d = √( 64 + 25 )

d = √89

d ≈ 9.4 units

The distance between point D and H to the nearest tenth is 9.4 units

The distance between two points is the length of the line segment joining them. Since the length of the line segment cannot be negative, the distance between two points is always positive.

The distance between two points is expressed as

S = √ X -x)² + (Y -y)²

= √ 9-1)² + 8-3)²

= √ 8² + 5²

= √ 64 +25

= √89

= 9.4 ( nearest tenth)

Therefore the distance between point D and H to the nearest tenth is 9.4 units

Answer:

Part a) The drawn in the attached figure

Part b)The slant height of the outside edge is [tex]x=10\ in[/tex]

Step-by-step explanation:

Part a) The drawn in the attached figure

Part b) What is the slant height of the outside edge?

we have that

The diameter of the base of the cone is 12 in

so

[tex]r=12/2=6\ in[/tex] ----> the radius is half the diameter

[tex]h=8\ in[/tex]

Applying the Pythagoras Theorem find the slant height x

[tex]x^{2}=r^{2}+h^{2}[/tex]

substitute the values

[tex]x^{2}=6^{2}+8^{2}[/tex]

[tex]x^{2}=100[/tex]

[tex]x=10\ in[/tex]

so the difference is 975 - 828.75 = 146.25.

now, if we take 975 to be the 100%, what is 146.25 off of it in percentage?

[tex]\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 975&100\\ 146.25&x \end{array}\implies \cfrac{975}{146.25}=\cfrac{100}{x}\implies 975x=14625 \\\\\\ x=\cfrac{14625}{975}\implies x=15[/tex]

Answer:

0.5amps

Step-by-step explanation:

I is inversely proportional to resistance

I = k/R

k = I/ R

k = 20/5

k = 4

This means that, I = 4/R

So, when R = 8ohms,

I = 4/8

 =0.5amps

Using Ohm's law, the inverse relationship between current and resistance in a simple circuit allows calculation of the new current as 12.5 amps when the resistance changes from 5 ohms to 8 ohms.

The student's question involves an application of Ohm's law, which is a fundamental principle in Physics that relates electric current (I), resistance (R), and voltage (V). According to Ohm's law, in a simple circuit, the current is inversely proportional to the resistance when the voltage is held constant. Given that the current is 20 amps when the resistance is 5 ohms, we can write the relationship as I1 * R1 = I2 * R2 where I1 and R1 are the initial current and resistance, and I2 and R2 are the final current and resistance we wish to find.

Plugging in the given values, we have:

20 amps * 5 ohms = current when resistance is 8 ohms * 8 ohms

Solving for the current when the resistance is 8 ohms:

20 amps * 5 ohms = I2 * 8 ohms

100 = I2 * 8

I2 = 100 / 8

I2 = 12.5 amps

Therefore, the current when the resistance is 8 ohms is 12.5 amps.

y = 4

or

y - 4 = 0(x - 3)

Step-by-step explanation:

The points (-2,4) and (3,4) have the same y-value. Because of this, the slope of the line will be 0 and the line will be horizontal. This means the line will have the equation y = b where b is the y-coordinate. The equation of the line is

y = 4.

In point slope form, the equation will have m = 0.

Answer:

B

Step-by-step explanation:

use the exponent rule of division: you just subtract the exponents if the base is the same, so 4-8=-4

The fraction with a numerator of 3.74 x 10⁻¹⁶ and a denominator of 10⁻³⁰ represented as a single exponential expression is 3.74 x 10¹⁴, obtained by dividing the digit terms and subtracting the exponents.

To represent the fraction as a single exponential expression, you follow the division of exponentials rule, which involves dividing the digit terms and subtracting the exponents of the exponential terms. Given the fraction with a numerator of 3.74 x 10-16 and a denominator of 10-30, you would divide 3.74 (the digit term of the numerator) by 1 (the implied digit term of the denominator) which is just 3.74, and subtract the exponents (-16 - (-30)) which equals 14. Therefore, the fraction as a single exponential expression is 3.74 x 1014.

Answer:

the answer to this is 7.9 or 7 13/14

Step-by-step explanation:

1. Divide both sides by 14

111/14 = 14g/14

2. Simplify

g = 7 13/14

Final answer:

The variable 'g' in the equation 111 = 14g is found by dividing 111 by 14, resulting in approximately 7.929 (rounded to 4 significant figures).

Explanation:

The equation given is 111 = 14g, which seems to be a simple algebra equation where you are solving for the variable g. To find g, you would divide both sides of the equation by 14 to isolate g.

This calculation yields: g = 111 / 14, which equals 7.92857142857. However, this number might need to be rounded depending on the context or instructions for significant figures. If the problem instructions mentioned 4 sig figs, the answer would be rounded to 7.929.

Step-by-step explanation:

There are several types of costs in this problem:

* Unique costs

* Costs that depend on the number of cars

* Costs that depend on the number of months

* Costs that depend on the number of months and the number of cars.

The costs that depend on the number of cars represent the coefficient of the variable n.

The costs that do not depend on the number of cars represent the constant value of the equation.

Then, to solve this problem you must identify the costs that do not depend on the number of cars.

These costs are:

* Membership Fee: $ 50 (one-time cost)

* Pull Pressure Check Cost: $ 15 per month

[tex]\$50 + \$15(12\ month) = \$230[/tex]
