HELPPP!!! ALGREBRA!!!

Answer: In mathematics, an algebraic expression is an expression built up from integer constants, variables, and the algebraic operations (addition, subtraction, multiplication, division and exponentiation by an exponent that is a rational number). For example, 3x2 − 2xy + c is an algebraic expression.

Step-by-step explanation:

Answer:

An algebraic expression includes variables. Variables are letters that stand for a potential number; most commonly you see x, y, and z used but you can use any letter. Constants are also common in algebraic expressions, and are numbers that are added or subtracted, as well as coefficients, which are what you multiply the variable by.

For example:

3x + 1

Here, the variable is x. The constant is 1. The coefficient is 3.

These are different then other expressions because of the addition of variables. 4 + 4 is not an algebraic expression, but 4x + 4 is.

Algebraic expressions also do not have equal signs, they are not equations.

They can also be more complicated than the ones I've expressed already. 3x^4 + 2x^2 + 4 is an algebraic expression too.

Hope this helps!

True

Step-by-step explanation:

This equation correctly represents the total cost of the food that the friends ended up paying for the popcorn and sodas. In this expression, the cost of each individual soda is represented by the variable x which is multiplied by 4 since each one of the four friend's purchased their own soda. After making this multiplication process that product is added to the initial $12 that they all spent together on the popcorn.

Each friend paid $4 for popcorn.

The total cost of the food can be represented by the expression 4x + $12.

Given

Four friends bought an extra-large $12 popcorn.

Each person bought their own drink.

Let x be the number of friends.

The total cost of food= Total number of friends + cost of popcorn.

The total cost of the food can be represented by the expression 4x + $12.

Therefore;

The amount paid by each friend is;

[tex]\rm 4x=12\\\\x=\dfrac{12}{3}\\\\x=4[/tex]

Hence, each friend paid $4 for popcorn.

Answer: U is the change in PE, m is the mass raised through a distance h. So, given m = 61.2 kg, each 1 m rise is an increase of (61.2)(9.8) = 600 J. Likewise, each floor (2.5 m) represents a change in PE of 1500 J for this mass.

Answer:chicken

Step-by-step explanation:

Put the chicken in the oven turn to 450 degrees let it sit for 4-5 hours

After 1 hour, 360 g decays to 180 g.

After another hour (total 2 hours), 180 g decays to 90 g.

After another hour (total 3), 90 g decays to 45 g.

After one more (total 4), 45 g decays to 22.5 g.

More quickly, with a half-life of 1 hour, the 360 g of starting material decays to

(360 g) / 2⁴ = 22.5 g

In general, if the half-life is 1 hour, then after n hours, an initial amount A of this substance decays according to

A / 2ⁿ

w = -6

Step-by-step explanation:

2w + 6 = -6

     -6      -6

2w = -12

÷2      ÷2

w = -6

Answer:

Step-by-step explanation:

w - 6 = 2w + 6

Subtract 6 from both sides

w - 12 = 2w

subtract 1w, or w, from both sides

-12 = w

Answer:

the commission earn by his brother is $2,790

Step-by-step explanation:

The computation of the commission earn by his brother is as follows

= Selling price of the truck × commission percentage

= $62,000 × 4.5%

= $2,790

Hence, the commission earn by his brother is $2,790

Answer: As x -> ♾, h(x) -> -♾, and as x -> -♾,h(x) -> -♾

Step-by-step explanation:

The end behavior is x ----> ∞ then h(x) ----> -∞, and when x ----> -∞ then h(x) -----> -∞.

In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

Given:

h(x) = -7[tex]x^6[/tex] + 3 [tex]x^4[/tex]– 5x².

If we plot the Equation on the Graph we can see a parabolic Curve.

This Curve tells as x tends to ∞ the value of h(x) tends to -∞.

and, when x tends to -∞ the value of h(x) tends to -∞.

Hence, the end behavior is x ----> ∞ then h(x) ----> -∞.

and, when x ----> -∞ then h(x) -----> -∞.
