Step-by-step explanation:

I'm  just writing this

The table is a linear function, and the rule for the input/output table is f(x) = 1 + 3x

From the table, we can see that:

The output of the table  is 1 more than 3 times the input

If the input is x, then the output y is:

y = 1 +3 * x

Evaluate

y = 1 + 3x

Hence, the rule for the input/output table is f(x) = 1 + 3x

Answer:

slope = - 1

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

given

x + y = - 7 ( subtract x from both sides )

y = - x - 7 ← in slope- intercept form

with slope m = - 1

Parallel lines have equal slopes

then the slope of a line parallel to it is - 1

Let's get it solved ~

We have been given length and width of a rectangle in terms of x ~

that is :

Area of the rectangle is given ~ i.e 24 unit²

Area of rectangle in terms of x is :

[tex]\qquad \sf  \dashrightarrow \:(x - 2) \sdot(x + 3) = 24[/tex]

[tex]\qquad \sf  \dashrightarrow \: {x}^{2} + 3x - 2x - 6= 24[/tex]

[tex]\qquad \sf  \dashrightarrow \: {x}^{2} +x - 6 - 24 = 0[/tex]

[tex]\qquad \sf  \dashrightarrow \: {x}^{2} +x -30= 0[/tex]

[tex]\qquad \sf  \dashrightarrow \: {x}^{2} + 6x - 5x - 30 = 0[/tex]

[tex]\qquad \sf  \dashrightarrow \: {x}^{}( x + 6) - 5(x + 6)= 0[/tex]

[tex]f(x) = \begin{cases}x = - 6 \: \textsf{ \: if \:x + 6 = 0 } \\ \\ x = 5 \: \: \: \: \: \: \textsf{if \: x - 5 = 0} \end{cases}[/tex]

but since side of a rectangle can't be negative, we have to take value of x as 5

now, Perimeter of rectangle is ~

[tex]\qquad \sf  \dashrightarrow \:2(width \: + \: length)[/tex]

[tex]\qquad \sf  \dashrightarrow \:2(x - 2 + x + 3)[/tex]

[tex]\qquad \sf  \dashrightarrow \:2(2x + 1)[/tex]

plug In the value of x ~

[tex]\qquad \sf  \dashrightarrow \:2(2(5) + 1)[/tex]

[tex]\qquad \sf  \dashrightarrow \:2(10 + 1)[/tex]

[tex]\qquad \sf  \dashrightarrow \:2(11)[/tex]

Answer: B

Step-by-step explanation:

The population (number of bacteria in the colony), 950 hours from that time, will be 260 bacteria

From the question, we are to determine what the population will be after 950 hours

From the given information,

The number of bacteria in a colony doubles every 475 hours

The current population is 65 bacteria

∴ After 475 hours, the new population will be 2 × 65 bacteria

New population after 475 hours = 130 bacteria

After another 475 hours (that is, 950 hours from the initial time),

The population will be 2 × 130 bacteria = 260 bacteria

Hence, the population, 950 hours from that time, will be 260 bacteria

Answer:

An Acre is a propduct of any rectangular plot of land giving a total of 4,046sqm OR 43,560sq ft. An Acre consist of 6 plots each measuring 6 x 120ft. In Lagos State, the standard size of a plot is 60 x 120ft (18m x 36m ie 648sqm), while in some other cities of the country, plots are measured in 50 x100ft.

Step-by-step explanation:

The roots of this equation equation are:

x1 = 4

x2 = 8

This sentence given in the statement of this question is: Equation of the Second Degree. There are a few ways to solve it, but let's calculate by the factorization method.

Equation given: x² - 12x + 36 = 4

x² - 12x + 36 = 4

12x ➯ 2x . x6

36 ➯ 6²

x² - 2x . x6 + 6²

( x - 6 )² = 4

( x - 6 )² = 4

x - 6 = ±√4

x - 6 = ±2

x - 6 = ±2

x - 6 = -2

x - 6 = +2

x - 6 = -2

x = -2 + 6

x = 4

x - 6 = +2

x = 2 + 6

x = 8

Therefore, the correct results of this equation, will be:

x1 = 4

x2 = 8

By taking the product between the rate and the time, we will see that he does not finish the book.

We know that he can read 5 pages in 15 minutes. Then in one hour he can read 4 times that: 4*5 pages = 20 pages.

We conclude that Carter reads 20 pages per day, then, if he reads for 14 hours, then he reads a total of:

20*14 = 280

So he will read 280 pages in these 14 hours, which means that he will not finish the book.

Step-by-step explanation:

Given

First term : 5

Second term : a₂ = 2(a₁ + 4)

Third term : a₃ = 2(a₂ + 4) = 2(18 + 4) = 2(22) = 44

Fourth term : a₄ = 2(a₃ + 4) = 2(44 + 4) = 2(48) = 96

Fifth term : a₅ = 2(a₄ + 4) = 2(96 + 4) = 2(100) = 200

Hence, the first 5 terms of the sequence are :

Answer: no solution  or  x ∈ Ø

Step-by-step explanation:

(2⁴ × x) ÷ 2x = 64

16x ÷ 2x = 64

[tex]\frac{16x}{2x} = 64[/tex]

8 = 64

8 = 64, x [tex]\neq[/tex] 0

For the exponential expression, [tex]16^{1/4}[/tex] the simplified value is 2.

First, we need to remember a rule for exponential expressions, it says that:

[tex]x^{1/n} = \sqrt[n]{x}[/tex]

Then we can rewrite the given exponential expression as:

[tex]16^{1/4} =\sqrt[4]{16}[/tex]

So, we just need to find a number that when multiplied by itself 4 times, is equal to 16.

We know that:

2*2 = 4

Then:

2*2*2*2 = 2⁴ = 4*4 = 16

Then we can conclude that:

[tex]16^{1/4} =\sqrt[4]{16} = 2[/tex]

So the simplified value of the exponential expression is 2.
