The Equivalent expressions of  4x+1/2+2x-3 is  6x × 1/2 - 3 .

Expressions that perform similarly but differ in appearance are said to be equivalent expressions. When the same value(s) for the variable are entered, two algebraic expressions that are equivalent will have the same value (s). An expression that is equivalent to another expression but does not share its visual characteristics has the same value or worth. According to algebra, the equivalent formulae 2(2x - 3y + 6) and 4x -6y + 12 are the same. When two expressions can be written similarly or when they can be combined into a single, simpler expression, they are said to be equivalent. Furthermore, if values are replaced for the variable in two expressions and they both yield the same result, you can tell if the expressions are similar.

Answer:

20.8 cm^2.

Step-by-step explanation:

Area = 1/2 * base * height

         = 1/2 * 8 * 5.2

Answer:

A = 20.8 cm²

Step-by-step explanation:

We have just to use the following expression:

A = (Base x height) / 2

So:

A = (8 x 5.2) / 2

A = 4 x 5,2

A = 20.8 cm²

The equation of the graph using the format y= a*|x-h|+k is y=|x+4|-5 .

In the question ,

From the graph we can see that the vertex of the graph is (-4,-5) ,

The absolute value equation of the graph is denoted by y=a*|x-h|+k ,

where (h,k) are the vertex of the graph .

Since (-4,-5) is the vertex , So h= -4 and k= -5 ,

Substituting the values of h and in the absolute value equation , we get

y=a*|x-(-4)|+(-5)

y=a*|x+4|-5

Take any point that lies on the graph ,

Selecting the point (1,0) which lie on the graph ,

Substituting the value as x=1 and y=0 , we get

0=a*|1+4|-5

5=a*|1+4|

5=5a

a=1 ,

Substituting the values of a=1 , h= -4 and k=-5 in the absolute value equation , we get y=|x+4|-5

Therefore , the equation of the graph using the format y= a*|x-h|+k is y=|x+4|-5 .

The solution of the algebraic expression for the variable M is given as follows:

M = (4π²a³)/(T²G)

To solve an algebraic expression for a variable, we have to isolate this variable, as a function of the other variables in the expression.

In the context of this problem, the expression which we want to solve for M is given as follows:

T² = 4π²a³/GM

Applying cross multiplication to remove the fraction, we have that:

T²GM = 4π²a³

To isolate M, we apply the division, which is the opposite operation of the multiplication, as T²G are multiplying M, hence the simplified expression for M is given as follows:

M = (4π²a³)/(T²G)

The solution for x in the equation is x = 2b/(2a - c)

The equation is given as

2ax - b = cx + b

Collect the like terms in the above equation

So, we have the following equation

2ax - cx = b + b

Evaluate the like terms in the above equation

So, we have the following equation

2ax - cx = 2b

Factor out x from the equation

x(2a - c) = 2b

Divide both sides by 2a - c

x = 2b/(2a - c)

Hence, the solution for x is x = 2b/(2a - c)

Considering the numeric value of the function f(x), the test average for your math class after completing test 2 was of 80.8.

To find the numeric value of a function, we replace each instance of the variable in the function by the desired value.

For this problem, the function is given by:

f(x) = 79 + 0.9x.

The average after test 2 is represented by the numeric value when x = 2, hence we replace the lone instance of x on the function to find the average as follows:

f(2) = 79 + 0.9(2) = 80.8.

The problem asks for the test average for your math class after completing test 2.

The function that gives the average after test x is:

The values ​​of the trigonometric functions of the 0° angle are, cos 0° = 1, sin 0° = 0 ,tan 0° = 0, cot 0° = ∞, sec 0° = 1 , cosec 0° = ∞.

The simplest definition of a trigonometric function is the function of an angle in a triangle, also known as a circular function. It implies that these trigonometric functions can be used to determine the relationship between a triangle's angles and sides. The fundamental trigonometric operations include sine, cosine, tangent, cotangent, secant, and cosecant.

Now given degree is 0 ,

So, we know that sin 0° = 0,

And cos 0° = 1,

⇒tanθ=sinθ/cosθ,

Here θ = 0°

⇒tan 0° = 0/1,

⇒tan 0° = 0,

Now as cot θ is the inverse of tan θ, we get,

⇒cot θ = 1/tan θ,

⇒cot 0°= 1/0,

⇒cot 0° = ∞,

Now we know that cosec θ is the inverse of sin θ, we get,

⇒cosec θ = 1/sin θ,

⇒cosec 0° = 1/0,

⇒cosec 0° = ∞

And we know that sec θ is the inverse of cos θ we get,

⇒sec θ = 1/cos θ,

⇒sec 0° = 1/1,

⇒sec 0° = 1.

The team has enough money that will be used to buy 11 baseball uniforms.

The information illustrated that the baseball team has $1,400 to buy baseball uniforms and each uniform costs $124.

It was also stated that the team needs to buy 11 uniforms. In this case, the cost of 11 uniforms will be the multiplication of the coat of each pair of uniform by the number of uniforms that will be bought.

This will be illustrated as:

= Amount of each uniform × Number of uniform

= $124 × 11

= $1364

Therefore, the total amount is $1364. Therefore, since the baseball team has $1400, the amount is enough.

Answer:

[tex]\dfrac{(x-2)^2}{9}-\dfrac{y^2}{4}=1[/tex]

Step-by-step explanation:

Given points:

Standard equation of a horizontal hyperbola (opening left and right):

[tex]\boxed{\dfrac{(x-h)^2}{a^2}-\dfrac{(y-k)^2}{b^2}=1}[/tex]

where:

Points (5, 0) and (-1, 0) are the vertices of the hyperbola.

The center (h, k) is midway between the vertices.  Therefore:

[tex]\implies h=\dfrac{5-1}{2}=2[/tex]

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

Substitute the found values of h and k into the formula:

[tex]\dfrac{(x-2)^2}{a^2}-\dfrac{y^2}{b^2}=1[/tex]

Substitute point (5, 0) and solve for a²:

[tex]\implies \dfrac{(5-2)^2}{a^2}-\dfrac{0^2}{b^2}=1[/tex]

[tex]\implies \dfrac{3^2}{a^2}=1[/tex]

[tex]\implies \dfrac{9}{a^2}=1[/tex]

[tex]\implies 9=a^2[/tex]

Substitute one of the (2±3√2, ±2) points and the found value of a² and solve for b²:

[tex]\implies \dfrac{(2+3\sqrt{2}-2)^2}{9}-\dfrac{2^2}{b^2}=1[/tex]

[tex]\implies \dfrac{(3\sqrt{2})^2}{9}-\dfrac{4}{b^2}=1[/tex]

[tex]\implies \dfrac{18}{9}-\dfrac{4}{b^2}=1[/tex]

[tex]\implies 2-\dfrac{4}{b^2}=1[/tex]

[tex]\implies \dfrac{4}{b^2}=1[/tex]

[tex]\implies 4=b^2[/tex]

Substitute the found values of a² and b², together with the values of h and k, into the formula to create the equation of the hyperbola:

[tex]\dfrac{(x-2)^2}{9}-\dfrac{y^2}{4}=1[/tex]

Solving a system of equations we can see that Lucy is 30 years old.

Let's define the variables:

L = Lucy's age.

F = father's age.

We know that when Lucy turns 15, her father was 3 times her age, so:

if L = 15

then F = 15*3 = 45

So her father is 30 years older than Lucy.

So we can write the linear relation:

F = L + 30

Now we know that this year, her father has exactly twice Lucy's age, then we have the system of equations:

F = L + 30

F = 2*L

Replacing the other equation here we get:

L + 30 = 2*L

30 = 2*L - L = L

30 = L

The probability of rolling an even number or a multiple of 3 is 3/4.

Probability determines the odds that a random event would happen. The probability the event takes place is 1 and the probability that the event does not happen is 0.

An even number is a number that is perfectly divisible by 2.

Probability of rolling an even number = number of sides that are even / total number of sides

Sides that are even = 2, 4, 6

Probability of rolling an even number = 3/6 = 1 / 2

Probability of rolling a multiple of 3 = number of sides that are multiples of 3  / total number of sides

Sides that are multiples of 3 = 3, 6

Probability of rolling a multiple of 3 = 2/6 = 1/2

The probability of event B or C = 1/4 + 1/2 = 3/4

Ava's age is 26 years when Ava and Olivia's ages are consecutive even integers and the sum of Ava's age and 2 times Olivia's age is 74.

According to the question,

Ava and Olivia's ages are consecutive even integers.

Now, let's take Olivia's age to be x years.

So, Ava's age would be (x+2) years because their ages are consecutive even integers. (Even numbers are the number which are divisible by 2.)

We have the sum of Ava's age and 2 times Olivia's age is 74.

So, we have the following expression:

(x+2+2x) = 74

3x+2 = 74

3x = 74-2

3x = 72

x = 72/3 (3 was in multiplication on the left hand side. So, it is in the division on the right hand side.)

x = 24 years

So, Olivia's age is 24 years.

Now, we have:

Ava's age = (x+2) years

Ava's age = (24+2) years

Ava's age = 26 years

Hence, Ava's age is 26 years.
