[tex]x^2 - 25 = 0\\x^2=25\\x=-5 \vee x=5[/tex]

Answer:

x = ± 5

Step-by-step explanation:

Given

x² - 25 = 0

There are 2 possible approaches to solving this equation

Approach 1

add 25 to both sides

x² = 25 ( take the square root of both sides )

x = ± [tex]\sqrt{25}[/tex] = ± 5

Approach 2

x² - 25 ← is a difference of squares and factors as

(x - 5)(x + 5) = 0 ← in standard form

Equate each factor to zero and solve for x

x - 5 = 0 ⇒ x = 5

x + 5 = 0 ⇒ x = 5

[tex]\bf x= \begin{cases} 6\\ -4 \end{cases}\implies \begin{cases} x=6\implies &x-6=0\\ x=-4\implies &x+4=0 \end{cases} \\\\\\ (x-6)(x+4)=\stackrel{y}{0}\implies \stackrel{\mathbb{F~O~I~L}}{1x^2-2x-24}=y[/tex]

Answer:

I(x) = 12x² + 8x + 5

Step-by-step explanation:

* Lets talk about the solution

- P(x) is a quadratic function represented graphically by a parabola

- The general form of the quadratic function is f(x) = ax² + bx + c,

  where a is the coefficient of x² and b is the coefficient of x and c is

  the y-intercept

- To find I(x) from P(x) change each x in P by 2x

∵ P(x) is dilated to I(x) by change x by 2x

∵ I(x) = P(2x)

∵ P(x) = 3x² + 4x + 5

∴ I(x) = 3(2x)² + 4(2x) + 5 ⇒ simplify

∵ (2x)² = (2)² × (x)² = 4 × x² = 4x²

∵ 4(2x) = 8x

∴ I(x) = 3(4x²) + 8x + 5

∵ 3(4x²) = 12x²

∴ I(x) = 12x² + 8x + 5

There are two: -4 and -5/2

Steps

0 = (2x - 5)(x + 4) | FOIL (distribution)

2x = 5 | zero product rule

x = 5/2 <<<

x = -4 <<< | zero product rule again.

Step-by-step explanation:

Answer:

The number in the square root is 50.

Step-by-step explanation:

Using the pythagorean theorem, we know that c is 10, so we plug in 2a^2=100, since we know that both of the leg lengths are the same.

Simplifying this equation gives a^2=50, which square rooting both sides gives

Answer:

C

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

here m = [tex]\frac{1}{2}[/tex] and (a, b) = (5, 1), so

y - 1 = [tex]\frac{1}{2}[/tex](x - 5)

The equation that represents a line that passes through (5, 1) and has a slope of 1/2 is; C: y - 1 = ¹/₂(x - 5)

The formula for equation of a line in point- slope form is expressed as;

y - b = m(x - a)

where;

m is the slope of line

(a, b) is a coordinate point on the line

In this question, we are given;

m = 1/2  and (a, b) = (5, 1)

The taxicab, after all its movements, is about 3.16 blocks away from its starting position. It ends up 3 blocks west and 1 block north from where it initially started.

The question asks us to determine the final position of a taxicab relative to its starting position after following a series of movements. The taxicab's starting position in this case is at the coordinate (1, -2).

Initially, it goes 4 blocks south (downwards in the grid, which we'll regard as negative) and 3 blocks east (to the right on the grid, which we'll regard as positive). Therefore, it moves to a point that is (+3, -4) relative to its starting position.

Next, it goes 6 blocks west (left on the grid, which is negative) and 5 blocks north (up on the grid, which is positive). So, this movement's relative position is (-6, +5).

To find out the final position of the taxicab relative to its starting position, we need to add up these movements' relative positions. The final relative position will be (+3-6, -4+5), which equals (-3, 1).

Hence, in terms of blocks, the taxicab is 3 blocks west and 1 block north of its starting position. The direct distance to the start would then be determined using the Pythagorean theorem, where the total distance is the square root of the sum of the squares of the movements in each direction (x and y coordinates). That forms the equation √((-3)² + 1²) = √10 ≈ 3.16 blocks.

Step-by-step explanation:

Let

x -----> number of cards Sophie has

y -----> number of cards Jackie has

we know that

x+y=30 -----> equation A  

y=x+5 -----> equation B

Solve by substitution

Substitute equation B in equation A and solve for x

x+(x+5)=30

x=12.5 cards

Note I assume the problem was invented without taking into account the result, because the amount of cards should be a whole number

Answer:

It's minimum value

and the value is :(1 , -2)

Answer:

see explanation

Step-by-step explanation:

Given

f(x) = 3x² - 6x + 1

To express in vertex form

f(x) = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Use the method of completing the square

The coefficient of the x² must be 1, so factor out 3

f(x) = 3(x² - 2x) + 1

add/subtract ( half the coefficient of the x- term )² to x² - 2x

f(x) = 3(x² + 2(- 1)x + 1 - 1) + 1

     = 3(x - 1)² - 3 + 1

     = 3(x - 1)² - 2 ← in vertex form

with vertex = (1, - 2)

To determine if vertex is a max/ min

• If a > 0 then minimum

• If a < 0 then maximum

here a = 3 > 0 ⇒ minimum at (1, - 2)

The minimum value is the y- coordinate of the vertex, that is

minimum value = - 2

Notice that we have a quantity of n = 20 data

Use the following formula to calculate the third quartile [tex]Q_3[/tex]

For a set of n data organized in the form:

[tex]x_1, x_2, x_3, ..., x_n[/tex]

The third quartile is  [tex]Q_3[/tex]:

Answer:

Mia multiplied one side of the equation by 5/3 and the other side by 3/5. This makes the equation unbalanced and untrue. x should be 50

Step-by-step explanation:

Mia made an error when setting up the equation to determine the total time allotted for the math section of the exam. She incorrectly set up the equation as 30 = (1/4) * x, instead of 30 = (1/4) * x. The correct solution is x = 120.

Mia made an error when setting up the equation to determine the total amount of time allotted for the math section of the exam. Since Mia spent 30 minutes answering the math questions, which was 1/4 of the total time, the correct equation should be:

30 = (1/4) * x

To solve for x, we need to multiply both sides of the equation by 4 to undo the division:

4 * 30 = x

x = 120

Therefore, the total amount of time allotted for the math section of the exam is 120 minutes, not 30 minutes as Mia mistakenly calculated.

Answer:

√55x\11x⁸y⁵

Step-by-step explanation:

Factor the numerator and denominator and cancel the common factors.

Answer: C

Explanation:

√55x⁷y⁶/11x¹¹y⁸

→ 55/11 = 5

→ x⁷/x¹¹= x⁷⁻¹¹= x⁻⁴

→ y⁶/y⁸= y⁶⁻⁸= y⁻²

→ √5/x⁴y²

→ √5/x²y

If the exponent is a negative, the base is the reciprocal of itself with a positive exponent.

Ex: 6⁻² = 1/6² = 1/36

The square root of an exponent with a positive, even power is half of that power.

Ex: √x⁴ = x²

Let x represent Ravi's current age.

Now, Ravi's age fifteen years from now is effectively Ravi's age plus fifteen, therefor we can write this as x + 15.

Four times Ravi's present age is four multiplied by his present age, therefor we can write this as 4x.

If Ravi's age fifteen years from now is equal to four times his present age, then:

x + 15 = 4x

Now all we have to do is solve for x to find Ravi's present age:

x + 15 = 4x

15 = 3x (Subtract x from both sides)

5 = x (Divide both sides by 3)

Therefor, Ravi's present age is 5 years.

Answer:

The correct options are B, C and D.

Step-by-step explanation:

It is given that the figure is a Japanese art of paper folding. It means the figure have many lines of symmetry (i.e., AK, IO, CM and NF).

From the figure it is clear that HV is larger than GW, so segment HV and GW are not pairs of congruent segments.

Therefore option A is incorrect.

[tex]\overline{IJ}\cong \overline{LM}[/tex]        (AK is line of symmetry)

[tex]\overline{AB}\cong \overline{AP}[/tex]        (AK is line of symmetry)

[tex]\overline{BC}\cong \overline{PO}[/tex]        (AK is line of symmetry)

Therefore the correct options are B, C and D.

From the figure it is clear that PO is smaller than ON, so segment HV and GW are not pairs of congruent segments.

Therefore option E is incorrect.

Answer: [tex](f+g)(x)=2x^2+2x-2[/tex]

Step-by-step explanation:

Given the function f(x), which is:

[tex]f(x)=-x^2 +6x-1[/tex]

And the function g(x), which is:

[tex]g(x) =3x^2-4x-1[/tex]

You can observe that [tex](f+g)(x)[/tex] indicates that you need to add the functions, then you know that:

[tex](f+g) (x)=(-x^2+6 x-1)+(3x^2-4x-1)[/tex]

Finally, to simplify it you must addthe like terms. Therefore, you get that  [tex](f+g)(x)[/tex] is:

[tex](f+g)(x)=-x^2+6 x-1+3x^2-4x-1[/tex]

[tex](f+g)(x)=2x^2+2x-2[/tex]

Answer:

A' = (- 5, - 1)

Step-by-step explanation:

The coordinates of point A = (- 6, 2)

Under the translation (x + 1, y - 3)

Add 1 to the x- coordinate of A and subtract 3 from the y- coordinate of A

A' = (- 6 + 1, 2 - 3) → A' = (- 5, - 1)

Based on the fact that there are  4 points which are given below, we have to move the trapezoid to the points of A will be (x+1, y-3). The coordinates of A be A(-6,2) =>A'(-5, -1)

A trapezoid is regarded as a  quadrilateral that has only one pair of opposite sides that are said to be parallel.

The points on the graph are:

A(-6,2) =>A'(-5, -1)

B(-5,4) =>B'( -4,1)

C(-2,4)=> C'(-1,1)

D( 1,2) => D'(2,-1)

It is made up of a right angles (called right trapezoid), and it can also contain a congruent sides (isosceles). Note that in the above, the only way the trapezoid  can fit into the translation movement (Point A)is if it is moved to the points of (x+1, y-3) on the graph.

The coordinates of A be A(-6,2) =>A'(-5, -1).

Answer:

Step-by-step explanation:

The question is asking for a system of equations, which make explanations easy. :)

Define the variables. Setting [tex]x[/tex] to the number of clubhouse seats sold and [tex]y[/tex] to the number of grandstand seats sold will be sufficient. The "let statement[s]" will be:

The number of equations shall be no less than the number of variables for the solution to be unique. There are two variables. It will take at least two equations to find a unique solution.

Everyone at the race need a seat. The number clubhouse seats plus the number of grandstand seats shall be the same as the number people at the race. There were 36,000 people. Therefore the first equation shall be:

[tex]x + y = 36000[/tex].

Every clubhouse seat will add $12.00 to the receipt. [tex]x[/tex] clubhouse seats will add $[tex]12\;x[/tex] to the receipt. Similarly, [tex]y[/tex] grandstand seats will add $[tex]5\;y[/tex] to the receipt. The two values shall add up to $250,000.

Drop the dollar sign to get the second equation:

[tex]12\;x +5\;y =250000[/tex].

Hence the system:

[tex]\displaystyle \left\{\begin{aligned}& x + y = 36000 && \textcircled{\raisebox{-0.9pt}1}\\ & 12\;x + 5\;y = 250000 && \textcircled{\raisebox{-0.9pt}2}\end{aligned} \phantom{\small credit for the raisebox hack: tex[dot]stackexchange[dot]com/questions/7032/good-way-to-make-textcircled-numbers}[/tex].

Solve this system.

The first non-zero coefficient in equation [tex]\textcircled{\raisebox{-0.9pt}1}[/tex] is already one. That's the coefficient for [tex]x[/tex]. Use multiples of equation [tex]\textcircled{\raisebox{-0.9pt}1}[/tex] to get rid of [tex]x[/tex] in other equations (equation [tex]\textcircled{\raisebox{-0.9pt}2}[/tex] in this case.)

[tex]-12[/tex] times equation [tex]\textcircled{\raisebox{-0.9pt}1}[/tex] is

[tex]-12 \;x - 12\;y = -432000[/tex].

Add [tex]-12\times \textcircled{\raisebox{-0.9pt}1}[/tex] to [tex]\textcircled{\raisebox{-0.9pt}2}[/tex] to get:

[tex]0\;x + -7\;y = -182000[/tex].

Divide both sides by -7 to get:

[tex]y = 26000[/tex].

Add -1 times this equation to equation [tex]\textcircled{\raisebox{-0.9pt}1}[/tex] to get:

[tex]x = 10000[/tex].

That is:

[tex]\displaystyle \left\{\begin{aligned}&x = 10000\\&y = 26000\end{aligned}[/tex].

Step-by-step answer:

Given:

5% annual interest (APR)

compounded daily

Principal = 500

Solution:

Since it is compounded daily, we first calculate the

daily rate =  5% / 365 = 0.05/365

After one year,

future value

= 500 ( 1 + 0.05/365)^365

= 525.634 (to the tenth of a cent)

note: sometimes a year is considered to be rounded to 360 days, or 366 days for a leap year, but there is practically no difference in the results for this problem.

Final answer:

To calculate the future value of a $500 deposit with a 5% annual interest rate compounded daily for one year, we use the compound interest formula. The resulting amount is approximately $525.64.

Explanation:

To calculate the value of a $500 deposit in a credit union that pays 5% annual interest compounded daily, we will use the formula for compound interest:

A = P(1 + (r/n))^(nt)

Where:

A = the amount of money accumulated after n years, including interest.

P = the principal amount (the initial amount of money).

r = the annual interest rate (decimal).

n = the number of times that interest is compounded per year.

t = the time the money is invested or borrowed for, in years.

Using the given information:

P = $500

r = 5% or 0.05 (as a decimal)

n = 365 (since the interest is compounded daily)

t = 1 year

Substituting the values into the formula:

A = 500(1 + (0.05/365))^(365*1)

After calculating, we get:

A ≈ $525.64

Therefore, the value of the $500 deposit at the end of one year with daily compounding at a 5% annual interest rate is approximately $525.64.
