The value of the expression at y = 2.5 is 6.25.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

y²

Substitute y = 2.5

= y²

= 2.5²

= 2.5 x 2.5

= 6.25

Thus,

The value is 6.25.

Answer:

y = -90x + 2000

Step-by-step explanation:

Hello There!

So we need to write an equation of the line in slope-intercept form

y = mx + b

where m = slope and b = y intercept

They give us everything in the caption

They say that a hot air balloon descends from 2000 feet at a constant rate of 90 feet per minute

Descends from 2000 feet indicates that the hot air balloon starts at 2000 feet

Thus this is the y intercept

Descends indicates that the slope is going to be negative because descend means to go down

The hot air balloon descends at a constant rate of 90 feet per minute

Thus meaning that the slope is -90

Now that we have everything we add it all together and get that the equation is

y = -90x + 2000

hope this helps :)

Answer:

y = -90x + 2000

Step-by-step explanation:

in y = mx+b, m is the slope and b is the y intercept

Therefore the y intercept is 2000

Now we have y = mx + 2000

Because the balloon descends at 90 ft/min, the m value is -90

So the answer is y = -90x + 2000

28.5^2

Step-by-step explanation:

The formula is, b(base)+c(height)= b+c over 2.  b+c/2.

B=19ft in this problem.

C=38ft

Knowing this, we can further simplify.

19+38/2

Now, we add 19 and 38.

(57)

57/2= 28.5

So, the anwser is 28.5^2

Step-by-step explanation: internet, not that smart to do it *-*

The equivalent values of the expression A = 4 + w + 12w are B = 4 + 13w and C = 2 ( 2 + 6w ) + w

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 ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

To find the expressions that are equivalent to 4 + w + 12w, we need to simplify the expression and see which of the given expressions have the same result.

4 + w + 12w = 4 + 13w

So, the equivalent expressions are (a) 4 + 13w and (c) 2(2 + 6w) + w.

Let's check the other options:

(b) 13w² + 4: This is not equivalent, as it involves squaring the w term.

(d) 16 + 2w: This is not equivalent, as it involves adding a constant term.

(e) 2(2 + 6w²): This is not equivalent, as it involves squaring the 6w term.

Hence , the two expressions that are equivalent to 4 + w + 12w are (a) 4 + 13w and (c) 2(2 + 6w) + w.
