Answer: -3.3°F

Step-by-step explanation:

In integers , we represent fall in quantity by negative numbers.

Since, the temperature at noon was 16.8°F . By dropping it by  20.1°F means there is a - 20.1°F  change in the temperature.

Then, the temperature at midnight = 16.8°F + (- 20.1°F)

=  16.8°F - 20.1°F

= -3.3°F

Hence, The temperature at midnight was -3.3°F .

How do you do the slope on a graph
Semmy [17]

I can't be entirely sure what you want to "do" about the slope,
but here is how to FIND it if you have the line on the graph:

-- You pick two points on the graph line.

-- Find the difference in 'y' between the two points.

-- Find the difference in 'x' between the two points.

-- The slope of the line between the two points is

             (the difference in 'y')
divided by
             (the difference in 'x') .

-- If the line on the graph is a straight line, then
the slope is the same everywhere on it.

Write the equation of the parabola in vertex form.
givi [52]

Answer: -9 = a(1 - 3)² + 3

Step-by-step explanation:

Vertex Form Equation:

y = a(x - h)² + k

vertex: (h, k) which means

h = 3

k = 3

because your vertex is (3, 3).

Your point is (1, -9) which is (x, y).

This means

x = 1

y = -9

Now, plug everything into your Vertex Form Equation:

-9 = a(1 - 3)² + 3

That’s your equation and final answer, but of course, if you need to, you can solve for a if you need to.

If a is positive, the parabola opens up. If a is negative, the parabola opens down.

Hope this helps!
