Find the inequality represented in the graph.

Answer:

x = -9 and 16

Step-by-step explanation:

1. Separate in two cases:

(a) -2x + 7 = 25          and          (b) -2x + 7 = -25

(a) -2x + 7 = 25  ⇒ subtract 7 from both sides

     -2x = 18 ⇒ divide both sides by -2

      x = -9

(b) -2x + 7 = -25 ⇒ subtract 7 to both sides

    -2x = -32 ⇒ divide both sides by -2

     x = 16

Solutions: x = -9, 16

Since every number here is divided by 3, the common ratio is 3.

To find the missing number, we should multiply 45 times the common ratio, 3:

Answer: 2

Step-by-step explanation:

DE * CE = AE * BE (Two Secants Segment Theorem)

▪︎ DE = 1 + x + 4

▪︎ CE = x + 4

▪︎ AE = 11 + x + 1

▪︎ BE = x + 1

=> (1 + x + 4)(x + 4) = (11 + x + 1)(x + 1)

=> (x + 5)(x+4) = (x + 12)(x + 1)

=> x^2 + 9x + 20 = x^2 + 13x + 12

=> 9x + 20 = 13x + 12

20 - 12 = 13x - 9x

8 = 4x

Using the quotient rule, it is found that the derivative of the function is given as follows:

[tex]f^{\prime}(x) = -\frac{1}{2\sqrt{s}(\sqrt{s}+2)^2}[/tex]

Suppose a quotient function defined as follows:

[tex]f(x) = \frac{g(x)}{h(x)}[/tex]

Then, the derivative is given by:

[tex]f^{\prime}(x) = \frac{g^{\prime}(x)h(x) - h^{\prime}(x)g(x)}{h(x)^2}[/tex]

In this problem, we have that:

Then, since g'(x) = 0, the derivative is given by:

[tex]f^{\prime}(x) = -\frac{1}{2\sqrt{s}(\sqrt{s}+2)^2}[/tex]

The required length ribbon needed to go around the package is 2(3x^2 + 2x -10) / (x^2 + x - 3).

Given that,
Package that had a length of 2x^2+3x-5/x^2+x-3 centimeters and width x^2-x-5/x^2+x-3.

How much ribbon would be needed to go around the package in centimeters is to be determined.

Perimeter is the measure of the figure on its circumference.

The rectangle is a four-sided polygon whose opposites sides are equal and has an angle of 90° between its sides.

Quantity of ribbon = perimeter of the rectangular package
                            = 2 * length + 2* width
                            = 2 * (2x^2+3x-5/x^2+x-3) + 2(x^2-x-5/x^2+x-3)
                            = 2 (3x^2 + 2x -10) / (x^2 + x - 3)

Thus, the required length of  ribbon needed to go around the package is 2(3x^2 + 2x -10) / (x^2 + x - 3).

Answer:

45

Step-by-step explanation:

perimeter is the sum of all sides

for rectangle, it's (length + width) x 2

so do the reverse: 146/ 2 = l + w

73-45 = 30 this means the longer side is 45

=> length is 45

Using it's concept, it is found that the probability of tossing heads and rolling a number less than 3 is given by:

C. 1/6

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem, there were 12 trials. Of those, 2 are H1 and H2, which are heads and a number less than 3, hence the probability is given by:

p = 2/12 = 1/6.

No it can't be factored , whenever there is addition between two squares , the expression can't be factored

Answer:

C

Step-by-step explanation:

since ∠ m ≅ ∠ p , then

9x - 2 = 4x + 18 ( subtract 4x from both sides )

5x - 2 = 18 ( add 2 to both sides )

5x = 20 ( divide both sides by 5 )

x = 4

then

∠ p = 4x + 8 = 4(4) + 18 = 16 + 18 = 34°

From simplification of the given algebra, the correct answers are as shown below.

1) (a² - b)/(a³b²)

This reduces to;

(a²/(a³b²)) - b/(a³b²)

⇒ a/(ab²) - 1/(a³b)

2) The algebraic expression is;

(b - a)/a³b³

⇒ b/a³b³ - a/a³b³

⇒ 1/a³b² - 1/a²b³

3) The algebraic expression is;

(2 - ab²)/(a²b³)

⇒ (2/(a²b³)) - (ab²)/(a²b³)

⇒ 2/(a²b³)) - 1/(ab)

4) The algebraic expression is;

(2 - ab²)/(a²b³)

⇒ 2/(a²b³) - 1/ab

Answer:

6x-6x56 =-2016

Step-by-step explanation:

You have to subtract, then multiply by 56 to get -2016, as it shows a negative.

Answer:

first line: 0, 4

explanation: middle of -12 and 12 is 0, then 12/3 = 4

second line: -9, 6

explanation: split into 4 sections per each 12 so 12/4 is 3 and the location of the first unknown point is one section away from 12 so we know the distance between there is 3, leaving -12+3 = -9. Then two sections less than 12 is 12-6 = 6

third line: -12, 4

explanation: 24/6 = 4, -24 + 12 = -12 so 4 units each sections 0 + 4 = 4

Answer with step-by-step explanation:

1) 4x - 24 = 1000

Add 24 to both sides.

4x = 1024

Divide both sides by 4.

x = 256

2) 7x = 343

Divide both sides by 7.

x = 49

3) x⁴ = 4096

Find 4th root of both sides.

The 95% confidence interval for the true proportion of first-year students who intend on majoring in liberal arts is option B. 0.62 plus-or-minus 1.96 start root start fraction 0.62 (1 minus 0.62) over 100 end fraction end root .

Confidence interval in statistics is defined as the certain range of values that you estimate for the unknown parameter lies within.

Confidence interval for the population proportion can be calculated as,

p ± z × [tex]\sqrt{\frac{p(1-p)}{n} }[/tex]

Here, p is the sample proportion and n is the sample size.

z value for 95% confidence interval is 1.96.

Here, n = 100,

p = [tex]\frac{62}{100}[/tex] = 0.62

Substituting the values, confidence interval of true proportion is,

0.62 ± 1.96 × [tex]\sqrt{\frac{0.62(1-0.62)}{100} }[/tex]

Hence the 95% confidence interval for the true proportion of first-year students who intend on majoring in liberal arts is 0.62 ± 1.96 × [tex]\sqrt{\frac{0.62(1-0.62)}{100} }[/tex].
