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

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

What is an expression?

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.

26.7%

Step-by-step explanation:

The positive change from 15 to 19 is 4.

Find the value of the fraction 4/15 and multiply the result by 100% to obtain the final answer:

4/15 = 0.26667

Multiplied by 100%, 0.26667 becomes 26.7%: the percentage change in the number of students
