what function is represented in the table ?- y = 3 (4x )- y = 2 ( .25x )- y = 4 ( .25 ) x - y = 4 ( 3x )

Answer:

Step-by-step explanation:

These types of functions are called Piecewise-defined functions since it use a different formula for different parts of its domain because it has a point of discontinuity.

We have the following function:

So, to find f(-4), we need to substitute x=-4 into the function for x≠1.

Now, for f(1) we know that the outcome is 4.

Then, for f(3), substitute x=3 into the function for x≠1.

The standard form of the quadratic function with vertex (-1,8) and passing through point (0,2) is y = -6(x+1)²+8.

An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as ax2 + bx + c = 0, where x is the variable, and a must not be zero.

The standard form of a quadratic equation in vertex form is given as,

y = a(x-h)² + 8

Where (h,k) is the coordinate of the vertex and a is constant.

Given the vertex  (h,k) = (-1,8)

Substitute, vertex, and  (0,2)

2 = a(0 + 1)² + 8

a = -6

Therefore, the equation converts as,

y = -6(x+1)²+8

Hence "The standard form of the quadratic function with vertex (-1,8) and passing through point (0,2) is y = -6(x+1)²+8".

The price after applying the tax would be the sum between the original value and the value equivalent to the established percentage, just like this:

Answer:

Variables are the letters that represent a number. So, it would be the ones bolded here: 3x=12 and y=1/2x-6

The coefficients are next to the variables-the ones being multiplied with the variable. They are bolded here: 3x= 12 and y= 1/2x-6

The constants are the numbers that aren't coefficients or variables. So they are bolded here: 3x=12 and y=1/2x-6

If we have half a dollar, three quarters, eight dimes, six nickels, and nine pennies , then we altogether have $2.44 .

In the question ,

it is  given that

we have half a dollar ,

which means half a dollar = $0.50

we have , three quarters means

we have 75 cents

and 75 cents = $0.75

we have 8 dimes ,

we know that 1 dime [tex]=[/tex] 10 cents

so , 8 dimes = 80 cents

and 80 cents = $0.80

we have six nickels,

we know that 20 nickels = $1

so , 1 nickel = $1/20

and 6 nickel = $ 6/20 = $0.30

we have nine pennies ,

we know that 100 pennies = $1

So ,1 Pennie = $1/100

and 9 pennies = $ 9/100 = $0.09

Combining  all together we get

total money = half a dollar + three quarters + 8 dimes + six nickels + nine pennies .

Substituting the values , we get

total money = $0.50 + $0.75 + $0.80 + $0.30 + $0.09

= $2.44

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

42 - 6 ÷ (6 - 3) = 40

Step-by-step explanation:

BODMAS

The BODMAS rule is an acronym representing the order of operations in math:

Given calculation:

42 - 6 ÷ 6 - 3 = 40

Following the order of operations, where division comes before subtraction, the current calculation is:

⇒ 42 - 6 ÷ 6 - 3

⇒ 42 - 1 - 3

⇒ 41 - 3

⇒ 38

Therefore, brackets should be added around (6 - 3) to make the calculation correct:

⇒ 42 - 6 ÷ (6 - 3)

⇒ 42 - 6 ÷ 3

⇒ 42 - 2

⇒ 40

After thoroughly calculation, we have come to find that, If equation x² = 25, where x ε z then x = √25 = 5, thus x is 5.

According to the converse of corresponding angles theorem, the statement that allows Carmen to conclude that lines p and q are parallel is: ∠2 ≅ ∠6.

A transversal is a line that crosses two straight lines. For example, line t is a transversal that crosses the lines p and q in the given diagram above.

Parallel lines are lines that do not meet each other at any point and are of equal distant to each other.

When a transversal intersects two parallel lines, they form angle pairs. One of such angle pairs is, corresponding angles, which are always congruent to each other.

Thus, if corresponding angles are formed and are equal to each other, then the lines they lie on must be parallel lines based on the corresponding angles converse theorem.

Angles 2 and 6 are corresponding angles that are formed by the transversal that intersects lines q and p. If they are congruent angles, then the lines are parallel.

Therefore, Carmen can use the statement, ∠2 ≅ ∠6 to show that lines q and p are parallel.
