Answer:

Variable y exponente.

Step-by-step explanation:

En una expresión algebraica la reducción de términos semejantes se da entre los términos de igual variable o incógnita y exponente.

Por ejemplo:

3x² + 5x²

se pueden reducir pues tienen la misma variable x y el mismo exponente 2, su resultado se genera solo sumando, restando, los coeficientes, en este caso 3 y 5

3x² + 5x² = 8x²

En el caso:

3y² + 5x²

No se puede reducir pues la variable o incógnita no son iguales:

x≠y

En el caso:

3x² + 5x³

No se pueden reducir pues su exponente no es igual.

The daughter's age is 7 years old.

An equation is a mathematical statement that shows that two mathematical expressions are equal.

Given that, a parent is 20 years older than twice his daughter's age, and he was half of his present age 17 years back.

Let the age of the parent be x,

He/she was half of the age 17 years back, then,

x/2 = x-17

x = 34

Therefore, parent's present age is 34 years.

He is  20 years older than twice his daughter's age,

Let his daughter's age be y,

2y+20 = 34

2y = 14

y = 7

Hence, his daughter's age is 7 years old.

The lengths of CF, EF and A.F are 6 units, 28 units and 16 units, respectively

From the question, the given parameters to solve the question are represented as

DF = 3

BF = 14

GF = 8

The point F in the triangle is the centroid of the triangle

This means that the point F divides the lines that passes through it in the ratio 1 : 2 or 2 : 1 (as the case may be)

The claim above also  means that

CF = 2 * DF

EF = 2 * BF

A.F = 2 * GF

Substitute the known values in the above equation, so, we have the following representation

CF = 2 * 3 = 6

EF = 2 * 14 = 28

A.F = 2 * 8 = 16

Hence, the lengths are 6 units, 28 units and 16 units

The function rule for the transformation of the graph f(x) = 2x

reflection over the x - axis (x, y) → (x, -y)

vertical compression of a factor of 1/4

Considering the given function  f(x) = 2x that requires reflection and vertical compression

The transformation rule for reflection over the x - axis

(x, y) → (x, -y)

comparing to the equation y = f(x) = 2x

-y = -2x

hence f(x) = -2x

vertical compression involves multiplying by 1/4

= 1/4 * f(x)

= 1/4 - 2x

-2x + 8 = -2x + 8

-2 makes the equation equal.

Option A is the correct answer.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 4 = 6 is an equation.

We have,

-2x + 8 = __x + 8

The equation has infinitely many solutions when both sides of the equation are equal.

Now,

-2x + 8 = -2x + 8 is equal on both sides.

Thus,

-2x + 8 = -2x + 8

-2 makes the equation equal.

Answer:its c

Step-by-step explanation:

Answer:

1.  c < -4

2.  -4 < c < 0

3.  c = 0

4.  c > 0

Step-by-step explanation:

[tex]\boxed{\begin{minipage}{6.8 cm}\underline{Discriminant}\\\\$b^2-4ac$ \quad when $ax^2+bx+c=0$\\\\when $b^2-4ac > 0 \implies$ two real roots.\\when $b^2-4ac=0 \implies$ one real root.\\when $b^2-4ac < 0 \implies$ no real roots.\\\end{minipage}}[/tex]

Given quadratic equation:

[tex]-x^2+4x+c=0[/tex]

If the quadratic equation has no real roots, then the discriminant is less than zero:

[tex]\implies b^2-4ac < 0[/tex]

[tex]\implies (4)^2-4(-1)(c) < 0[/tex]

[tex]\implies 16+4c < 0[/tex]

[tex]\implies 4c < -16[/tex]

[tex]\implies c < -4[/tex]

If the quadratic equation has two real roots, then the discriminant is greater than zero:

[tex]\implies b^2-4ac > 0[/tex]

[tex]\implies (4)^2-4(-1)(c) > 0[/tex]

[tex]\implies 16+4c > 0[/tex]

[tex]\implies 4c > -16[/tex]

[tex]\implies c > -4[/tex]

Using Descartes' Rule of Signs, if c > 0 there would be one sign change and so a maximum of one positive root.  If c < 0 there would be 2 sign changes and therefore a maximum of 2 negative roots.

Therefore, for the two roots to have the same sign, -4 < c < 0.

If c = 0 then:

[tex]\implies -x^2+4x=0[/tex]

[tex]\implies -x(x+4)=0[/tex]

[tex]\implies x(x+4)=0[/tex]

Therefore, the roots would be 0 and -4 so there would be one negative root and one root equal to zero.

Using Descartes' Rule of Signs, if c > 0 there would be one sign change and so a maximum of one positive root.

Therefore, for the equation to have two roots with opposite signs, c > 0.

The expression 3(n + 1) is equivalent to the given expression 7n-(4n-3).

The measurements of [x] and [y] are 37 and 61 respectively.

In Euclidean geometry, a parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure. A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically -

∠x + ∠y + ∠z = 180°

There are different types of triangles such as -

equilateral triangle , scalene triangle , isosceles triangle etc.

Given are two triangles as shown in the figure.

Triangles ΔMPN and ΔSTU are congruent. We can write -

2x - y = 13

2x - 50 = 24

Now -

2x - 50 = 24

2x = 74

x = 37

then -

2 x 37 - y = 13

74 - 13 = y

y = 61

Hope this helps!

The linear function that represents the situation is of:

C(y) = 13y + 145.

The intercept is of:

C(0) = 145, meaning that the flat fee to pay the game is of $145.

The slope-intercept representation of a linear function is given by the rule presented as follows:

y = mx + b

The coefficients of the function and their meaning are listed as follows:

Two points of the function, from the table, are given as follows:

(8, 249) and (13,314).

The slope is given by the change in y of the two points divided by the change in x, hence:

m = (314 - 249)/(13 - 8) = 13.

Hence:

C(y) = 13y + b

When y = 8, C(y) = 249, hence the intercept b of the function is obtained as follows:

249 = 13(8) + b

b = 249 - 13 x 8

b = 145.

Meaning that the flat fee to pay the game is of $145.
