Answer: -15

Step-by-step explanation:

[tex]x^{4}[/tex] + 24 = 105

subtract 24 from both sides of the equation .

[tex]x^{4}[/tex] = 105 - 24

[tex]x^{4}[/tex] = 81

find the fourth root of both sides

x = 3

Therefore : substitute x = 3 to find the value of [tex]x^{2} -24[/tex]

[tex]x^{2}[/tex] - 24  =  [tex]3^{2}[/tex] - 24

= 9 - 24

Keshawn could include the following statements in his explanation:

The domain of both functions is all real numbers.

The range of f(x) is y > 0.

The range of g(x) is y > 0.

Options A, D, and E are the correct answer.

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

f(x) = 5x

g(x) = 5

The domain of a function is the set of all possible input values.

The range of a function is the set of all possible output values.

Now,

For both of these functions, the domain is all real numbers.

This is because we can plug in any value for x and get a valid output.

For example:

If we plug in x = 0, we get.

f(0) = 5(0) = 0

g(0) = 5

For both functions, we get a valid output, even though they are different. We can do this for any real number value of x.

Now,

For f(x) = 5x, the range is y > 0.

This is because the function produces positive output values for any positive input value of x, and negative output values for any negative input value of x.

The only value for which f(x) produces a zero output is x = 0, but this is not included in the range since it is not greater than zero.

For g(x) = 5,

The range is also y > 0.

This is because the function produces a constant output of 5 for any value of x. Since 5 is greater than zero, the range of g(x) is also y > 0.

Thus,

The domain of both functions is all real numbers.

The range of f(x) is y > 0.

The range of g(x) is y > 0.

Final answer:

The expanded form of 4(7x+3) is achieved by using the distributive property, resulting in the expression 28x + 12.

Explanation:

The expanded form of the algebraic expression 4(7x+3) involves distributing the 4 to both terms inside the parentheses. This is accomplished using the distributive property of multiplication over addition. The steps are as follows:

Multiply 4 by 7x to get 28x.

Multiply 4 by 3 to get 12.

Combine these products to express the expanded form.

Therefore, the expanded form of 4(7x+3) is 28x + 12.

As for evaluating complex expressions such as 2+x(−7+x(2+x(−8+x(−2+3x)))), you would begin by substituting the value of x and simplifying from the innermost parentheses outwards. However, this is a different exercise than simply expanding an algebraic expression.

Answer:

[tex]x=-3[/tex]

Step-by-step explanation:

Given the equation

[tex]7=|3x+9|+7[/tex]

1. Use Addition property of equality, add -7 to both sides:

[tex]7-7=|3x+9|+7-7\\ \\0=|3x+9|[/tex]

2. The absolute value of the number is 0 if and only if the number is 0, so

[tex]3x+9=0[/tex]

3. Use Addition property of equality, add -9 to both sides:

[tex]3x+9-9=0-9\\ \\3x=-9[/tex]

4. Use Division property of equality, divide both sides by 3:

[tex]\dfrac{3x}{3}=\dfrac{-9}{3}\\ \\x=-3[/tex]

The solution is x = -3.

To solve the equation 7 = |3x + 9| + 7, let us follow these steps:

First, we simplify absolute value expression:

7 = |3x + 9| + 7

0 = |3x + 9|

The absolute value of a number is zero only when the number itself is zero. So, we set the expression inside the absolute value equal to zero:

3x + 9 = 0

3x = -9

x = -3

The solution to the equation is x = -3.

  ∠(-5i+10j) ≈ 116.57°

Step-by-step explanation:

The magnitude is given by the Pythagorean theorem:

  |-5i+10j| = √((-5)² +10²) = √125 = 5√5

The direction is found using the arctangent function. The angle is a second-quadrant angle.

Answer:

Step-by-step explanation:

Value of x should be  less than (-6).

x = { .......,-9,-8,-7}

For example:

-15*-7 +80 = 105+80 = 185 >170

The solution to the inequality -15x + 80 > 170 is x < -6. We subtract 80 from both sides and then divide by -15, remembering to reverse the inequality sign.

The question provided asks for the solution to the inequality -15x + 80 > 170. To solve the inequality, we can follow these steps:

Therefore, the solution to the inequality is all values of x that are less than -6.

Answer:

I have solved the question and it is in the picture above I solve the quadratic equation using factorization method I can solve it using the quadratic formula or completing the square method if you want any of these just comment below thank you bye

Given expression: 21 + (36 + 0 + 19)

Using identity property of addition: a + 0 = a

21 + (36 + 0 + 19) = 21 + (36 + 19)

Using commutative property of addition: a + b = b + a

21 + (36 + 19) = 21 + (19 + 36)

Using associative property of addition: a + (b + c) = (a + b) + c

21 + (19 + 36) = (21 + 19) + 36

Now, add two numbers inside the bracket.

(21 + 19) + 36 = 40 + 36

Using closure property of addition: a + b = c any number.            

40 + 36 = 76

Hence 21 + (36 + 0 + 19) = 76.

Answer:

[tex]x^{2} +14x=0[/tex]

Step-by-step explanation:

Given:

Given root is

[tex]x=-14,\ 0[/tex]

Now we need to find the quadratic equation for given roots.

Solution:

The given roots are -14 and 0.

So, the sum of the roots.

[tex]\alpha +\beta = -14 + 0[/tex]

[tex]\alpha +\beta = -14[/tex]

Product of the given roots

[tex]\alpha\times \beta = -14\times 0[/tex]

[tex]\alpha\times \beta = 0[/tex]

Therefore, the required quadratic equation is.

[tex]x^{2} -(\alpha +\beta )x+\alpha\times \beta=0[/tex] -------------------(1)

Now we substitute [tex](\alpha +\beta )[/tex] and [tex](\alpha\times \beta)[/tex] in equation 1.

[tex]x^{2} -(-14)x+0=0[/tex]

[tex]x^{2} +14x=0[/tex]

Therefore, the quadratic equation for the given root is. [tex]x^{2} +14x=0[/tex]

Second option: On a coordinate plane, rectangle A'B'C'D' prime has points [tex](-4,4),(12,4),(12,-4),(-4,-4)[/tex]

(See the graph attached)

Step-by-step explanation:

For this exercise it is importnat to know that a Dilation is defined as a transformation in which the Image (The figure obtained after the transformation) has the same shape as the Pre-Image (which is the original figure before the transformation), but they have different sizes.

In this case, you know that the vertices of the rectangle ABCD ( The Pre-Image)  are the following:

[tex]A(-1,1)\\\\B(3,1)\\\\C(3,-1)\\\\D(-1,-1)[/tex]

Therefore, to find the vertices of the rectangle A'B'C'D' (The Image)  that results of dilating the rectangle ABCD by a factor of 4 about the origin, you need to multiply the coordinates of each original vertex by 4. Then, you get:

[tex]A'=((-1)(4),(1)(4))=(-4,4)\\\\B'=((3)(4),(1)(4))=(12,4)\\\\C'=((3)(4),(-1)(4))=(12,-4)\\\\D'=((-1)(4),(-1)(4))=(-4,-4)[/tex]

Finally, knowing those points, you can identify that the graph that shows the result of that Dilation, is the one attached.

Answer:

[tex]f(\frac{2}{9})=1[/tex]

Step-by-step explanation:

we have

[tex]f(x)=3x+\frac{1}{3}[/tex]

we know that

f(2/9) is the value of the function f(x) when the value of x is equal to 2/9

so

For x=2/9

substitute the value of x in the function and solve for f(x)

[tex]f(x)=3(\frac{2}{9})+\frac{1}{3}[/tex]

[tex]f(x)=\frac{2}{3}+\frac{1}{3}[/tex]

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

[tex]f(x)=1[/tex]

therefore

[tex]f(\frac{2}{9})=1[/tex]

Answer:

No

Step-by-step explanation:

No, only if the triangle is a right triangle.

Final answer:

No, the centroid of a triangle is not necessarily the center of the circle circumscribing it. The centroid and circumcenter are distinct points that coincide only in equilateral triangles.

Explanation:

No, the centroid of a triangle is not necessarily the center of the circle circumscribing it. The centroid is the point of intersection of the medians of the triangle, which are the lines connecting each vertex to the midpoint of the opposite side. On the other hand, the circumcenter of a triangle is the center of the circle that passes through all three vertices of the triangle.

In some cases, the centroid and circumcenter might coincide, but this happens only when the triangle is equilateral. In all other cases, the centroid and circumcenter are distinct points.

For example, an equilateral triangle has its centroid and circumcenter at the same point. However, in an isosceles triangle, the centroid will lie on the line segment connecting the midpoint of the base to the opposite vertex, while the circumcenter will lie on the perpendicular bisector of the base.

Answer:

7850 square units

Step-by-step explanation:

According to the question;

We are required to find the area of the circle;

Perimeter of a circle = pi × D or 2 pi r

Therefore;

Rearranging the formula;

D = Perimeter ÷ pi

Taking pi to be 3.14

Then;

Diameter = 314 units ÷ 3.14

              = 100 units

But, radius = Diameter ÷ 2

                  = 100 units ÷ 2

                  = 50 units

We also need to know how we calculate the area of a circle;

Area of a circle = pi×r²

Therefore;

Taking pi as 3.14

Then, Area = 3.14 × 50²

                   = 7850 square units

Thus, the area of the circle is 7850 square units
