#1

Option C

[tex]\\ \sf\longmapsto (x-2)(x-4)[/tex]

[tex]\\ \sf\longmapsto x(x-4)-2(x-4)[/tex]

[tex]\\ \sf\longmapsto x^2-4x-2x+8[tex]

[tex]\\ \sf\longmapsto x^2-6x+8[/tex]

#2

Option A

[tex]\\ \sf\longmapsto (x-7)(x+7)[/tex]

[tex]\\ \sf\longmapsto x^2-7^2[/tex]

[tex]\\ \sf\longmapsto x^2-49[/tex]

#3

Option A

[tex]\\ \sf\longmapsto (x-6)(x-2)[/tex]

[tex]\\ \sf\longmapsto x^2+6x+2x+12[/tex]

[tex]\\ \sf\longmapsto x^2+8x+12[/tex]

Split up the integrand into partial fractions:

(31 - x)/(x² + x - 20) = (31 - x)/((x + 5)(x - 4))

= a/(x + 5) + b/(x - 4)

= (a (x - 4) + b (x + 5))/((x + 5)(x - 4))

= (5b - 4a + (a + b) x)/((x + 5)(x - 4))

Then a + b = -1 and 5b - 4a = 31. Solving for a and b yields a = -4 and b = 3, so

(31 - x)/(x² + x - 20) = -4/(x + 5) + 3/(x - 4)

Now integrating is trivial; the antiderivative is

-4 ln|x + 5| + 3 ln|x - 4| + C

and by the fundamental theorem of calculus, we end up with

[tex]\displaystyle \int_0^1 \frac{31-x}{x^2+x-20} \, dx = (-4\ln|1+5|+3\ln|1-4|) - (-4\ln|0+5|+3\ln|0-4|) \\\\ = -4\ln(6) + 3\ln(3) + 4\ln(5) - 3\ln(4) \\\\ = \ln\left(\frac{3^3\cdot5^4}{4^3\cdot6^4}\right) \\\\ = \ln\left(\frac{625}{3072}\right) \approx -1.592[/tex]

Step-by-step explanation:

Decimals can be written in fraction form. To convert a decimal to a fraction, place the decimal number over its place value. For example, in 0.6, the six is in the tenths place, so we place 6 over 10 to create the equivalent fraction, 6/10. If needed, simplify the fraction.

Answer: D) y = -3x + 5

Step-by-step explanation:

Move x.

3y = -9x + 15

Divide by 3.

y = -3x + 5

Hope it helps :) and let me know if you want me to elaborate.

Answer:

D. y = -3x + 5

Step-by-step explanation:

Subtract 9x from both sides

3y = 15 - 9x

y = 15/3 - 9x/3

y = 5 - 3x

y = -3x + 5

The equivalent ratio of 9:25 is 36:100.

Ratio expresses the degree of proportionality between two or more numbers. It expresses the number of times one number is contained in another number.  

In order to make the ratios equal, the relationship that exists between 9 and 36 has to be determined. 36 is a multiple of 9. It is 9 multiplied by 4. So, in order to make the ratios equal, multiply, 25 by 4.

25 x 4 = 100

Step-by-step explanation:

Answer:

Let x = the number

A negative number is 42 less than its square ⇒

x = x2 - 42

x2 - x - 42 = 0

(x - 7)(x + 6) = 0

x = 7 or -6

But since it is given that x is negative, the final answer is x = -6.

Answer:

Step-by-step explanation:

Justice needs $72 to fence in his garden.

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

Justice needs 24 feet of fencing to surround his garden.

The fencing is priced at $0.25 per inch.

Since, 1 foot = 12 inch

Hence, 24 feet = 24 x 12 inch = 288 inch.

Cost of the fencing in one inch = $0.25

So, Cost of the fencing in 288 inch = 288 x 0.25

                                                      = $72

Thus, Justice needs $72 to fence in his garden.

A function can be represented on graphs and a graph can also be represented as a function.

The values of f(x) = 3 are -1 and -4

The graph of the function is given as:

[tex]\mathbf{y = f(x)}[/tex]

Substitute 3 for y

[tex]\mathbf{f(x) = 3}[/tex]

From the graph;

x = -4 and x = -1, when f(x) = 3

This means that:

The solutions for f(x) = 3 are x = -4 and x = -1
