Answer: For a translation, you need a distance and a direction.

For a rotation, you need a point that is the center of the rotation and the degree (and sometimes direction) of rotation.

For reflection you need the axis or a defined line that the triangle is reflected across.

Kirk:

5' 4" tall

Joey

4' 8" tall

1.1 - Convert to inches

Kirk: 5' = (12*5) inches (Every foot is 12 inches) = 60 inches + 4 = 64 inches

Joey: 4' = (12*4) inches = 48 inches + 8 = 56 inches

1.2 - Find the difference

64 - 56 = 8 inches (Since its not divisible by 12 we leave it as is.)

Answer: To find the y-intercept, begin at the origin and move vertically to the graphed line.

To find the x-intercept, begin at the origin and move horizontally to the graphed line.

Step-by-step explanation:

There seems to be a typographical error in the answer choices.

To find the y-intercept you move vertically, up or down the y-axis.

To find the x-intercept you move horizontally, right or left the x-axis.

I made the corrections in my answer.

The description of the equation in the answers, "m = StartFraction y 2 minus y 1 Over x 2 minus x 1 EndFraction." looks like

[tex]m=\frac{{y_{2-y_{1} } } }{x_{2-x_{1} } }[/tex]  It means to put the difference in y-values 0 -(-6) in the numerator

and put the difference in the x-values in the denominator 3 - 0.  Simplify, Then divide.

I hope this helps!

Answer:

answer is C.

Step-by-step explanation:

Juan victor gave a 25% gratuity of $12 on a bill that was $48 which is correct option(B).

Percentage is defined as ratio expressed as a fraction of 100.

Scenarios modeled using given diagram

Here, let gratuity  [tex]s_1=s_2=s_3=s_4=25[/tex] %

[tex]s_1+s_2+s_3+s_4=[/tex]25%+25%+25%+25%=100%

25% of  total bil $48 is $12

So, $12+$12+$12+$12=$48

Hence, Juan victor gave a 25% gratuity of $12 on a bill that was $48.

Answer:

Step-by-step explanation:

How can we solve equations such as the cubic equation shown here?

   x3 − x2 – 4x + 4 = 0

There is an extremely complicated formula for solving cubic equations. Some calculators have this formula built in and therefore can be used to solve cubic equations.

We are going to learn how these equations can be solved by factorising. If the equation has solutions that are integers  a, b and c then we can factorise the equation as follows:

   x3 − x2 – 4x + 4 = (x − a)(x − b)(x − c) = 0

Multiplying the brackets together we see that the constant term, 4, must be the number we get when we multiply a, b and c together.

   abc = 4

All the solutions a, b and c must be factors of 4 so there are not many whole numbers that we need to consider.

We have only the following possibilities:

   ±1, ±2 and ±4

We’ll examine each of these numbers to find which ones are solutions of the equation.

   f(1) = 13 − 12 – 4×1 + 4 = 0                        1 is a solution

   f(−1) = (−1)3 − (−1)2 – 4×(−1) + 4 = 6    

   f(2) = 23 − 22 – 4×2 + 4 = 0                         2 is a solution

  f(−2) = (−2)3 − (−2)2 – 4×(−2) + 4 = 0        −2 is a solution

We have now found three solutions so we don’t need to try  4 and −4 as a cubic equation has a maximum of three solutions.

These three numbers give us the values of a, b and c and we can  factorise the equation.

   x3 − x2 – 4x + 4 = (x − 1)(x − 2)(x + 2) = 0

This method involves finding integers that are factors of ( can be divided into ) the constant term and then testing whether these integers are solutions of the equation.

Unfortunately we cannot assume that the solutions of a third degree equation are all integers.

However, if we can find one integer solution, lets say it is x = a then, by the remainder theorem , we know that (x − a) is a factor of the equation. We can find another factor, a quadratic factor,  by division. We can then solve the quadratic equation by using the formula for solving quadratics.

Example 1

Solve the equation x3 − 3x2 – 2x + 4 = 0

We put the numbers that are factors of 4 into the equation to see if any of them are correct.

   f(1) = 13 − 3×12 – 2×1 + 4 = 0                        1 is a solution

   f(−1) = (−1)3 − 3×(−1)2 – 2×(−1) + 4 = 2    

   f(2) = 23 − 3×22 – 2×2 + 4 = −4

   f(−2) = (−2)3 − 3×(−2)2 – 2×(−2) + 4 = −12

   f(4) = 43 − 3×42 – 2×4 + 4 = 12

   f(−4) = (−4)3 − 3×(−4)2 – 2×(−4) + 4 = −100

The only integer solution is x = 1. When we have found one solution we don’t really need to test any other numbers because we can now solve the equation by dividing by (x − 1) and trying to solve the quadratic we get from the division.

Now we can factorise our expression as follows:  

   x3 − 3x2 – 2x + 4 = (x − 1)(x2 − 2x − 4) = 0

It now remains for us to solve the quadratic equation.  

   x2 − 2x − 4 = 0

We use the formula for quadratics with a = 1, b = −2 and c = −4.

We have now found all three solutions of the equation x3 − 3x2 – 2x + 4 = 0. They are: eftirfarandi:

   x = 1

   x = 1 + Ö5

   x = 1 − Ö5

Example 2

We can easily use the same method to solve a fourth degree equation or equations of a still higher degree. Solve the equation f(x) = x4 − x3 − 5x2 + 3x + 2 = 0.

First we find the integer factors of the constant term, 2. The integer factors of 2 are ±1 and ±2.

   f(1) = 14 − 13 − 5×12 + 3×1 + 2 = 0                       1 is  a  solution

   f(−1) = (−1)4 − (−1)3 − 5×(−1)2 + 3×(−1) + 2 = −4

   f(2) = 24 − 23 − 5×22 + 3×2 + 2 = −4

   f(−2) = (−2)4 − (−2)3 − 5×(−2)2 + 3×(−2) + 2 = 0   we have found a second solution.

The two solutions we have found 1 and −2  mean that we can divide by x − 1 and x + 2 and there will be no remainder. We’ll do this in two steps.

First divide by x + 2

Now divide the resulting cubic factor by    x − 1.

We have now factorised

f(x) = x4 − x3 − 5x2 + 3x + 2 into

f(x) = (x + 2)(x − 1)(x2 − 2x − 1)  and it only remains to solve the quadratic equation

x2 − 2x − 1 = 0.  We use the formula with a = 1, b = −2 and c = −1.

Now we have found a total of four solutions. They are:

   x = 1

  x = −2

  x = 1 +

  x = 1 −

hopefully this helps!:)

Answer:

Which two equations represent the same function?

A) y = 2x – 7  and f(x) = 7 – 2x

B) 3x = y – 2  and f(x) = 3x – 2

C) f(x) = 3x2 + 5 and y = 3x2 + 5

D) None of the above

Show/Hide Answer

A) y = 2x – 7  and f(x) = 7 – 2x

Incorrect. These equations look similar but are not the same. The first has a slope of 2 and a y-intercept of −7. The second function has a slope of −2 and a y-intercept of 7. It slopes in the opposite direction. They do not produce the same graph, so they are not the same function. The correct answer is f(x) = 3x2 + 5 and y = 3x2 + 5.

B) 3x = y – 2  and f(x) = 3x – 2

Incorrect. These equations represent two different functions. If you rewrite the first equation in terms of y, you’ll find the equation of the function is y = 3x + 2. The correct answer is f(x) = 3x2 + 5 and y = 3x2 + 5.

C) f(x) = 3x2 + 5 and y = 3x2 + 5

Correct. The expressions that follow f(x) = and y = are the same, so these are two different ways to write the same function: f(x) = 3x2 + 5 and y = 3x2 + 5.

D) None of the above

Incorrect. Look at the expressions that follow f(x) = and y =. If the expressions are the same, then the equations represent the same exact function. The correct answer is f(x) = 3x2 + 5 and y = 3x2 +

Answer:

z = 11

Step-by-step explanation:

Simplifying

17 + 3(z + -2) + -11z = -7(z + 2) + 14

Reorder the terms:

17 + 3(-2 + z) + -11z = -7(z + 2) + 14

17 + (-2 * 3 + z * 3) + -11z = -7(z + 2) + 14

17 + (-6 + 3z) + -11z = -7(z + 2) + 14

Combine like terms: 17 + -6 = 11

11 + 3z + -11z = -7(z + 2) + 14

Combine like terms: 3z + -11z = -8z

11 + -8z = -7(z + 2) + 14

Reorder the terms:

11 + -8z = -7(2 + z) + 14

11 + -8z = (2 * -7 + z * -7) + 14

11 + -8z = (-14 + -7z) + 14

Reorder the terms:

11 + -8z = -14 + 14 + -7z

Combine like terms: -14 + 14 = 0

11 + -8z = 0 + -7z

11 + -8z = -7z

Solving

11 + -8z = -7z

Solving for variable 'z'.

Move all terms containing z to the left, all other terms to the right.

Add '7z' to each side of the equation.

11 + -8z + 7z = -7z + 7z

Combine like terms: -8z + 7z = -1z

11 + -1z = -7z + 7z

Combine like terms: -7z + 7z = 0

11 + -1z = 0

Add '-11' to each side of the equation.

11 + -11 + -1z = 0 + -11

Combine like terms: 11 + -11 = 0

0 + -1z = 0 + -11

-1z = 0 + -11

Combine like terms: 0 + -11 = -11

-1z = -11

Divide each side by '-1'.

z = 11

Simplifying

z = 11

Answer:

25%

18%+25%=43%

The correct answer should be A.

First consider that 2357/1180 is around 2. So the first part must have the answer of times 2. Then decide how many zeroes must be added. By simple math if you do 118,000,000,000 * 20 (which is [tex]2*10^1[/tex]) then you get 2,360,000,000,000. which is roughly the correct number.
