Answer:

[tex]x=0,\;x=\dfrac{1}{3}[/tex]

Step-by-step explanation:

Given equation:

[tex]\sqrt{x}=\sqrt{3}x[/tex]

Square both sides:

[tex]\implies \left(\sqrt{x}\right)^2= \left(\sqrt{3}x\right)^2[/tex]

[tex]\implies x= \left(\sqrt{3}\right)^2 \cdot \left(x\right)^2[/tex]

[tex]\implies x=3x^2[/tex]

Subtract x from both sides:

[tex]\implies x-x=3x^2-x[/tex]

[tex]\implies 0=3x^2-x[/tex]

[tex]\implies 3x^2-x=0[/tex]

Factor out the common term x:

[tex]\implies x(3x-1)=0[/tex]

Apply the zero-product property:

[tex]\implies x=0[/tex]

[tex]\implies 3x-1=0 \implies x=\dfrac{1}{3}[/tex]

Answer:

[tex] \sf \: x = \frac{1}{3} \: (or) \: x = 0[/tex]

Step-by-step explanation:

The equation given is,

→ √x = √3x

Now the value of x will be,

→ √x = √3x

→ x = (√3x)²

→ x = 3x²

→ 3x² = x

→ 3x² - x = 0

→ (3x - 1)(x) = 0

→ 3x - 1 = 0 || → x = 0

→ 3x = 0 + 1 || → [ x = 0 ]

→ 3x = 1 ||

→ [ x = 1/3 ] ||

These are the values of x.

Answer: 5x − 4 > 2x + 3

Step-by-step explanation:

The expression 5x − 4 > 2x + 3 looks like an equation but with the equals sign replaced by an arrowhead. It is an example of an inequality. This denotes that the part on the left, 5x − 4, is greater than the part on the right, 2x + 3.

An equation of the line that passes through the point (6, 0) and had a slope of -5/6 is y = -5x/6 + 5.

Mathematically, the point-slope form of a straight line can be calculated by using this mathematical expression:

y - y₁ = m(x - x₁)

Where:

Given the following parameters:

Substituting the given parameters into the point-slope formula, the equation of the line is given by;

y - y₁ = m(x - x₁)

y - 0 = -5/6(x - 6)

y = -5x/6 + 5

Answer:

G

Step-by-step explanation:

a proportional relationship is defined by

y = ax

that means, if x = 0, then also y = 0.

let's look at the slope (the constant of change) :

y coordinate change / x coordinate change

when going from 1 point to another in the line.

we see e.g. for (4, 9) and (5, 12)

x changes by +1 (from 4 to 5).

y changes by +3 (from 9 to 12).

the slope is +3/+1 = 3.

but the slope cannot be the "constant of proportionality" ("a" above), because starting e.g. from (2, 3) to get to x = 0 would mean

x has to change by -2 (= -2×1).

and then y has to change by -6 (= -2×3) to keep the same slope "alive".

and so, for x = 0, we would get y = -3. but not 0.

the only equation with slope 3 (the factor of x, yes) is in G.

therefore, G is the right answer.

we can also check, when using x = 4, x = 5 and x = 2, we get the given y-values (9, 12, 3) from y = 3x - 3.

so, it is correct.

As per the given equation, the first plant is produce 2x+21 more items than second plant.

The term equation is known as a mathematical statement that shows that two mathematical expressions are equal.

Here we have given that the first plant produces 5x+14 items daily

And the second plant produces 3x-7 items daily

In order to find the number of items produced on first plant, then we have to calculate the differences between number of items by the two plants daily, then it can be written as by using the equations,

=> (5x+14) - (3x-7)

Now, we have to expand the equations, then we get

=> 5x+14 - 3x+7

=> 2x+21

Therefore, first plant produces 2x+21 more items daily than the second plant.

Andrew would need to invest $61,300 for the account to reach $93,000.

Compound interest is defined as the amount of interest which has been calculated on the principal amount as well as the amount accumulated over the previous period is also included.

The equation to find final amount in compound interest is,

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

Here A is the final amount, P is the initial amount, r is the rate of interest, n is the number of times compounding is done in a year, t is the time in years.

Given, A = $93,000

t = 19 years

r = 2.2% = 0.022

n = 4 (since compounding is quarterly)

93,000 = P [1 + (0.022/4)]^(4×19)

93,000 = P [1.0055]^(76)

93,000 = P (1.517)

P = 61,297.8516

To the nearest hundred dollars, P = $61,300

Hence the principal amount Andrew need to invest is $61,300.

The exponential form of 8x8x8x8 is 2^(4*3) = 2^12.

The midpoint formula is used to find the center point of a line segment, given the coordinates of the two endpoints. The formula is as follows:

Midpoint = ( (x₁+ x₂) / 2, (y₁ + y2) / 2 )

Where (x₁, y₁) and (x₂, y₂) are the coordinates of the two endpoints of the line segment.

To find the missing coordinate using the midpoint formula, you would need to have the coordinates of one endpoint, as well as the coordinates of the midpoint. Then, you can use the formula to solve for the missing coordinate.

For example, if you have the coordinates of one endpoint as (3, 5) and the coordinates of the midpoint as (4, 6), you can use the formula to solve for the missing endpoint:

Midpoint = ( (3 + x₂) / 2, (5 + y₂) / 2 )

(4, 6) = ( (3 + x₂) / 2, (5 + y₂) / 2 )

So, by solving above equation we can get the missing coordinate

(x₂, y₂) = (5,7)

In conclusion, the midpoint formula can be used to find the missing coordinate of a line segment by using the coordinates of one endpoint and the midpoint. It is a simple and efficient way to find the missing coordinate when working with geometric shapes.

The total volume of the object  is 40 in³

The volume of a solid object encompasses the space and capacity that the object can occupy. Here, we have two shapes that make up the solid object, a cylinder, and a sphere. A cylinder is an object that resembles a tube and has two circular sides with the same radius linked by a flat round surface.

The volume of the cylinder is calculated by using the formula:

V = πr²h

V = 3 * 2² * 3         ..... (since radius r = d/2 = 4/2 = 2)

V = 3 * 4 * 3

V = 36 in³

The volume of the sphere = 4/3 πr³

V = 4/3 * 3 * 1³

V = 4 in³

The total volume of the object =  volume of the cylinder + volume of the sphere

The total volume of the object = 36 in³ + 4 in³

The reflection of (-3, 2) over the y-axis is (-3, -2).

The reflection of a point (x, y) over the y-axis is (x, -y).

Therefore, the reflection of (-3, 2) over the y-axis is (-3, -2).

To calculate the reflection of (-3, 2) over the y-axis, we first use the formula (x, -y).

In this case, x = -3 and y = 2, so the reflection of (-3, 2) over the y-axis is (-3, -2).

We can also calculate the reflection of (-3, 2) over the y-axis using the distance formula.

The distance formula  is d = √(x2-x1)2 + (y2-y1)2

In this case, x1 = -3, x2 = 0, y1 = 2, and y2 = 0.

Therefore, the distance d = √(02-(-3)2 + (02-2)2 = √(9 + 4) = √13

The reflection of (-3, 2) over the y-axis is (-3, -2). This can be verified using the distance formula.

d = √(x2-x1)2 + (y2-y1)2 = √(-3-0)2 + (-2-0)2 = √(9+4) = √13

The distance d is equal to the distance between (-3, 2) and (-3, -2). Hence, the reflection of (-3, 2) over the y-axis is (-3, -2).

and the cost of each mango = $0.75

Camila has $7. 75 to spend.

This means, the total cost of apples and mangos together must be less than or equal to 7.75

So, we get an inequality,

0.50x + 0.75y ≤ 7.75

And she must buy no less than 11 apples and mangos altogether.

x + y ≥ 11

consider a system of equations.

0.50x + 0.75y = 7.75

0 to the 0 exponents is undefined or indeterminate, and it's not considered as a valid mathematical operation.

The value of 0 to the 0 exponents is undefined or indeterminate. The reason for this is that the mathematical definition of exponentiation states that any number to the power of 0 is equal to 1, except for 0, which is undefined. However, when we try to apply this rule to 0 to the power of 0, it creates a paradox.

If we assume that 0 to the 0 exponents is 1, then any number raised to the power of 0 would be equal to 1, which is not true. For example, 2 to the power of 0 is not equal to 1, but 2, so this assumption doesn't hold true.

On the other hand, if we assume that 0 to the 0 exponents is 0, then any number multiplied by 0 would be 0, which is not true either. For example, 2 multiplied by 0 is not equal to 2.

Therefore, 0 to the 0 exponents is undefined or indeterminate, and it's not considered as a valid mathematical operation.

It's important to note that in some fields of mathematics such as limit, the value of 0 to the 0 exponent is defined as 1, but this is limited to the context of limit and not in general math.
