8 0

Answer:

y = -12

Step-by-step explanation:

You first calculate the x coordinate using the equation x = $\frac{-b}{2a}$ , which in this case is $\frac{-8}{8} = -1$ .

Then plug that x value into the equation to get the y coordinate:

4(-1)²+8(-1)-8 = -12

Find the midpoint of the segment with the following endpoints. (10, 7) and (5, 4)

KatRina [158]

Answer:

$\frac{15}{2} , \frac{11}{2}$

Step-by-step explanation:-

To find the midpoint, the equation we use is:-

$\frac{x1 +x2}{2} , \frac{y1 + y2}{2}$

x1 = 10

x2 = 5

y1 = 7

y2 = 4

Substituting the values in the equation, we get:-

$\frac{10+5}{2} , \frac{7+4}{2}$

Coordinates of the midpoint---> $\frac{15}{2} , \frac{11}{2}$

Is 9.99 rational or irrational

aleksley [76]

Answer:

Rational

Step-by-step explanation:

A rational number can be written as a fraction of the form.

$\frac{a}{b} \: where \: b \ne0$

and a and b are integers.

$9.99 = \frac{999}{100}$

Hence in this case a=999 and b=100.

Since both are integers with b being a non-zero integer, we conclude that 9.99 is a rational number.
