Pre-Algebra

Step-by-step explanation:

Step 1: Define equation

4(x - 1) = 2(6 - 2x)

Step 2: Solve for x

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Here we see that 4 does indeed equal 4.

∴ x = 2 is a solution of the equation.

MY EXPLANATION THAT HOW TO GET THE SQUARE:

Trying to factor as a Difference of Squares:

4.1 Factoring: 4x2 - 9

Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)

Proof : (A+B) • (A-B) =

A2 - AB + BA - B2 =

A2 - AB + AB - B2 =

A2 - B2

Note : AB = BA is the commutative property of multiplication.

Note : - AB + AB equals zero and is therefore eliminated from the expression.

Check : 4 is the square of 2

Check : 9 is the square of 3

Check : x2 is the square of x1

Factorization is : (2x + 3) • (2x - 3)

Answer:

16.67

166.7

1667

16670

Step-by-step explanation:

Any number to the zeroth power is 1, so the first one is 1 x 16.67, which equals to 16.67

10 to the first power is just 10, so multiply 10 x 16.67 for the second one. This equals 166.7

10 to the second power is 10 x 10 or 100, so multiply 100 x 16.67, which is 1667.

10 to the third power is 10 x 10 x 10 or 1000, so multiply 1000 x 16.67, which is 16670.

Basically, for each one, starting with 10 to the first power, move the decimal to the right one place.

Answer:

Step-by-step explanation:

just did it

Answer:

It means that you need to state whether there are any solutions and how many there are. For example if the equation ends up with an answer like 2=5 there is no solution because 2 does not equal 5. if the equation ends up with an answer of 0=0 there is infinitely many solutions because 0 does equal 0. if it comes out as x=9 there is one solution because x only has one answer to (keep in mind these are just examples)

Answer:

The  final price of the smart phone if you use the store credit card is $339.5

Step-by-step explanation:

Given;

original price of the smart phone = $679

initial discount = 35%

additional discount if you use the store credit card = 15%

total discount of the smart phone if you use the store credit card

= 35% + 15% = 50%

The final price of the smart phone, if you use the store credit card is given as;

P = 0.5 X $679

P = $339.5

Therefore, the  final price of the smart phone if you use the store credit card is $339.5

Answer:

$13.25

Step-by-step explanation:

First you add everything up to get you to $15.70, then the 20% is changed to .2 which you then multiply 15.70 by .2 giving you 3.14. You then take 15.70 minus 3.14 which then gets you to 12.56. Then you take the tax of 5.5% and times $12.56 by it, giving you 69 cents, as your tax. Add those together to get 13.25, and then your finished.

Answer:

$13.25

Step-by-step explanation:

First let's add together the cost of all the items Maria bought:

3.50 + 2.25 + 9.95 = 15.70

The total cost of all the items without a coupon or tax is $15.70.

If Maria uses a 20% coupon, the value of the total cost will be 80% of its original value. So, multiply 15.7 by 0.8 to find the cost after the coupon:

15.7 * 0.8 = 12.56

The new total cost is 12.56. Now we need to find the sales tax. Multiply 12.56 by 0.055 to find the value of the sales tax:

12.56 * 0.055 = 0.6908

0.6908 rounds to 0.69. Add the cost of the sales tax to the total cost to get the final answer:

12.56 + 0.69 = 13.25

The total cost Maria will pay is $13.25

Hope this helps :)

Answer:

D. Since none of the sides are congruent, it is not a right triangle.

Step-by-step explanation:

This is the weirdest triangle I've ever seen.

Since none of the sides have slopes that are negative reciprocals, it is not a right triangle. Therefore, option C is the correct answer.

The given triangle ABC has vertices A(-3, -5), B(0, 4) and C(2, 5).

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The formula to find the slope of a line is slope = (y2-y1)/(x2-x1)

Here, slope of AB is

m= (4+5)/(0+3)

= 3

Slope of BC is

m= (5-4)/(2-0)

= 1/2

= 0.5

Slope of CA is

m= (5+3)/(2+3)

= 8/5

= 1.6

Since none of the sides have slopes that are negative reciprocals, it is not a right triangle. Therefore, option C is the correct answer.

Answer:

The solution set is { } or ∅ ⇒ empty set

Step-by-step explanation:

∵ 2x + 10 < 10

→ Subtract 10 from the two sides of the inequality

∵ 2x + 10 - 10 < 10 - 10

∴ 2x < 0

→ Divide both sides by 2

∴ [tex]\frac{2x}{2}[/tex] < [tex]\frac{0}{2}[/tex]

∴ x < 0

∴ The solutions are all the negative numbers

∵ x ∈ N

∵ N is the set of Natural numbers

→ The natural numbers start at 1 and include all positive whole numbers

∴ N = {1, 2, 3, 4, 5, ..............}

∵ N does not contain any negative numbers

∴ The solution set is an empty set ⇒ ∅

∴ The solution set is { } or ∅

Answer:

The coordinates of P are (-2,0)

The radius of the circle is 5.

Step-by-step explanation:

Analytic geometry

The diagram shows a circle with center P, and two points A(-6,3) and B(2,-3) that form the diameter of the circle.

a)

The center of the circle lies at the midpoint of A and B. The midpoint (xm,ym) can be calculated by:

[tex]\displaystyle x_m=\frac{x_1+x_2}{2}[/tex]

[tex]\displaystyle y_m=\frac{y_1+y_2}{2}[/tex]

Substituting x1=-6, x2=2, y1=3, y2=-3:

[tex]\displaystyle x_m=\frac{-6+2}{2}=\frac{-4}{2}=-2[/tex]

[tex]\displaystyle y_m=\frac{3-3}{2}=0[/tex]

Thus, the coordinates of P are (-2,0)

b) The radius of the circle is the distance from the center to any point in its circumference. We can use the distance from P to A or B indistinctly.

Given two points A(x1,y1) and P(x2,y2), the distance between them is:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Substituting x1=-6, x2=-2, y1=3, y2=0:

[tex]r=\sqrt{(-2+6)^2+(0-3)^2}[/tex]

[tex]r=\sqrt{4^2+(-3)^2}[/tex]

[tex]r=\sqrt{16+9}=\sqrt{25}=5[/tex]

The radius of the circle is 5.
