If f (x) = –2x – 3 and the domain of f is {-4,0,6} , what is the range of
f (x)?

Answers

Answer:

[tex]\lbrace 5,\, -3,\, -15 \rbrace[/tex].

Step-by-step explanation:

The domain of a function includes all the values that this function could accept as inputs. The function would give a (possibly non-unique) output for each of these inputs. The range of this function over this particular domain would be the set of all the possible output values from this function.

In this question, the domain of this function is [tex]\lbrace -4,\, 0,\, 6 \rbrace[/tex], meaning that this function could accept [tex]x = (-4)[/tex], [tex]x = 0[/tex], and [tex]x = 6[/tex] as possible inputs.

[tex]f(-4) = -2 \times (-4) - 3 = 8 - 3 = 5[/tex].[tex]f(0) = -3[/tex].[tex]f(6) = -2 \times 6 - 3 = -15[/tex].

In other words, the possible output values of this function over this domain are [tex]5[/tex], [tex](-3)[/tex], and [tex](-15)[/tex]. Hence, the range of this function would be the set [tex]\lbrace 5,\, -3,\, -15 \rbrace[/tex].

Answers

6(x-2) > 15

6x - 12 > 15

6x > 27

x > 27/6

Hope it helps!

Answer:

x>4.5

Step-by-step explanation:

6(x-2)>15

We do this is as if it were an equation:

6(x-2)>15

Expand the brackets:

6x-12>15

Add 12 to both sides:

6x-12+12>15+12

Simplify:

6x>37

Now we divide both sides by 6:

6x÷6>37÷6

x > 4.5

If we put 5 into the original equation as it is more than 4.5, we get:

6(5-2)>15

We can simplify the brackets or expand first:

Simplifying the brackets first:

6(3)>15

If 5 boxes cost $35, what is the cost per box?

a) x+4
is a factor of f(x)=x3−x2−20x
Factor completely if so

b) x−6
is a factor of g(x)=x4−6x3−8x+48
Factor completely if so

c) x+7
is a factor of h(x)=x3−37x+84
Factor completely is so

Answers

Answer:

  a) f(x) = x(x +4)(x -5)

  b) g(x) = (x -6)(x -2)(x^2 +2x +4)

  c) h(x) = (x +7)(x -3)(x -4)

Step-by-step explanation:

To factor completely generally means to find binomial factors that have integer constants. It is helpful to be familiar with the idea of "greatest common divisor", and what the product of two binomial factors looks like. In particular, there are a couple of special forms that can be useful. One of them is the difference of squares. Another is the difference of cubes.

  a² -b² = (a -b)(a +b)

  a³ -b³ = (a -b)(a² +ab +b²)

In the general case, the product of binomial factors is ...

  (x -a)(x -b) = x² -(a+b)x +ab

The coefficient of the x-terms is the sum of the binomial constants; the constant term is their product.

__

a)

The given cubic has no constant term. That is, every term has a factor of x, so that is one of the factors.

  f(x) = (x)(x^2 -x -20)

The given factor of x+4 tells you the constant in the other factor is -20/4 = -5.

  f(x) = x(x +4)(x -5)

__

b)

We observe that the ratios of pairs of coefficients are ...

  1 : -6 and -8 : 48 = 1 : -6 . . . . . pairs of coefficients have the same ratio

That means we can factor each pair of terms:

  g(x) = x^4 -6x^3 -8x +48

  g(x) = x^3(x -6) -8(x -6) = (x^3 -8)(x -6)

Using the difference of cubes formula, the factorization is ...

  g(x) = (x -2)(x^2 +2x +4)(x -6)

Note: the quadratic factor has irrational complex roots.

__

c)

The quadratic factor of this cubic can be found by dividing it by the given factor. That is most easily accomplished using synthetic division. Explaining how to do that is beyond the scope of this answer. The first attachment shows that the resulting factorization is ...

  h(x) = (x +7)(x^2 -7x +12)

The quadratic is factored by finding two factors of 12 that have a sum of -7. The positive sign of their product (12) tells you both will be negative.

  12 = (-1)(-12) = (-2)(-6) = (-3)(-4)

The pair of factors with a sum of -7 is -3 and -4. These are the constants in the remaining binomial factors:

  h(x) = (x +7)(x -3)(x -4)

_____

Additional comment

A graphing calculator can be an invaluable tool for factoring higher-degree polynomials. The graph of h(x) in the second attachment, for example, shows you the zeros are -7, 3, 4, so the factors are (x+7)(x-3)(x-4).

For a function like g(x), you can find the real zeros from the graph, then you can find the quadratic by factoring out the associated factors. The vertex of the quadratic curve helps you write the expression for that. (see the third attachment)

  g(x) = (x -2)(x -6)((x +1)^2 +3) . . . . quadratic factor in vertex form

  g(x) = (x -2)(x -6)(x^2 +2x +4)

Answer:x=9

Step-by-step explanation:so this is a isosceles triangle so that means the two sides are equal so set up the equation as 3x-7=20. And by moving the 7 over it will be 3x=27 and then you want you separate the x and to do that you have to divide x and 27 by 3 and you answer is x = 9

Hey there!


3x - 7 = 20°


ADD 7 to BOTH SIDES

3x - 7 + 7 = 20 + 7

CANCEL out: -7 + 7 because it give you 0

KEEP: 20 + 7 because it help solve for the x-value


NEW EQUATION: 3x = 20 + 7


SIMPLIFY IT!


3x = 27


DIVIDE 3 to BOTH SIDES

3x/3 = 27/3

CANCEL out: 3/3 because it give you 1

KEEP: 27/3 because it help solve for the x-value


NEW EQUATION: x = 27/3


SIMPLIFY IT!

x = 9



Therefore, your answer is: x = 9

what iis 5.46 ÷ 0.25 (show ur work)

Answers

Answer:

21.84

Step-by-step explanation:

5.46/0.25 is actually just 5.46 * 4 but an easier way to do this is just doing

5.46 * 2 which is 10.92

.46 + .46 is .92
5+5 is 10
so thats 10.92

and since we only did times 2 we have to double it

so 10.92 + 10.92

10 + 10 is 20
.92 + .92 is 1.84

20 + 1.84 is 21.84

                        2 1 . 8 4

                                        1 . 0 0

                                        1 . 0 0

Therefore, 5.46 divided by 0.25 = 21.84.

R 694.4

Explanation:

simple interest = [tex]\sf{\dfrac{PRT}{100}[/tex] → [tex]\sf \dfrac{560*8*3}{100}[/tex] → R 134.4

where p refers to principal, r refers to rate, t refers to time.

total money:

invested money + simple interest

R 134.4 + R 560 → R 694.4

Answer:

R 694.40

Step-by-step explanation:

Simple interest formula:

A = P(1 + rt)

where A is the final amount, P is the initial principal balance, r is the annual interest rate (in decimal format), and t is time (in years)

Given:

P = 560r = 8% = 0.08t = 3

⇒ A = 560(1 + 0.08 · 3)

⇒ A = 560(1.24)

⇒ A = 694.40

(iii) -2.0.

Answers

The z scores of 1.5, -0.5 and -2.0 corresponds with a raw score of 650, 450 and 300

What is z score

Z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:

z = (x - μ) / σ

Where x = raw score, μ = mean and σ = standard deviation.

Given that σ = 100, μ = 500, hence:

a) For z = 1.5:

1.5 = (x - 500)/100

x = 650

b) For z = -0.5:

-0.5 = (x - 500)/100

x = 450

c) For z = -2:

-2 = (x - 500)/100

x = 300

The z scores of 1.5, -0.5 and -2.0 corresponds with a raw score of 650, 450 and 300

Answers

Answer:

82 cm^2

Step-by-step explanation:

First, find the formulas for the areas of all of the shapes shown

area of rectangles = base * height

area of triangle = 1/2 * base * height

for the triangle at the top, area = 1/2 * 5 * 2 = 5 cm^2

for the bottom triangle, area = 1/2 * 5 * 2 = 5 cm^2

for the left rectangle, area = 6 * 3 = 18 cm^2

for the middle rectangle, area = 5 * 6 = 30 cm^2

for the right triangle, area = 4 * 6 = 24 cm^2

add all of these together

5 + 5 + 18 + 30 + 24 = 82 cm ^2

A triangle has a base length of 2ac² and a height 6 centimeters more than the base length. Find the area of the triangle if a = 4 and c = 2.

Answers

Answer:

608 cm²

Step-by-step explanation:

base = 2ac²

base = 2x4x2²

base = 2x4x4

base = 32cm

height = base + 6cm

height = 32 + 6cm

height = 38cm

Area of triangle = ½ x base x height

Area = ½ x 32 x 38

Area = 1216/2

Area = 608 cm²

Therefore the area of the triangle is 608cm²

Answer: Choice B is correct

========================================================

Explanation:

Use a graphing tool like GeoGebra, Desmos, or your graphing calculator to plot each expression given as a separate y equation. Four parabolas should result.

The x intercept is the same as the root or zero of a function.

You should find that only choice B has a root thats larger than 4. That specific root being x = 7.

----------------------------

A non-graphing approach:

You can use the quadratic formula or the factoring method to find the roots.

For choice A, it factors to (x+5)(x+6) = 0. The roots are x = -5 and x = -6 which aren't greater than 4. So we cross choice A off the list. Choices C and D are similar stories.

On the other hand, choice B factors to (x-7)(x+2) = 0 and it has roots of x = 7  and x = -2. This is another way to see why choice B is the answer.

Here are the steps for the quadratic formula for choice B

[tex]x = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x = \frac{-(-5)\pm\sqrt{(-5)^2-4(1)(-14)}}{2(1)}\\\\x = \frac{5\pm\sqrt{81}}{2}\\\\x = \frac{5\pm9}{2}\\\\x = \frac{5+9}{2} \ \text{ or } \ x = \frac{5-9}{2}\\\\x = \frac{14}{2} \ \text{ or } \ x = \frac{-4}{2}\\\\x = 7 \ \text{ or } \ x = -2\\\\[/tex]

The quadratic formula is handy in case factoring is either not possible, or guess-and-check is too lengthy of a process. As you can probably tell, we could use the quadratic formula's results to help construct the factored form.
