The points (8, -10) and (-21, 4) form a line segment.

Citrus2011 [14]

Answer:

The coordinates of the midpoint are;

(-6.5, -3)

Step-by-step explanation:

Here, we want to get the midpoint of the line segment

To get this, we use the midpoint formula;

(x,y) = (x1 + x2)/2, (y1 + y2)/2

Thus;

(x,y) = (8 - 21)/2, (-10 + 4)/2

(x,y) = -13/2 , -6/2

(x,y) = (-6.5 , -3)

Yeast , a key ingredient bread , thrives within the temperature range of 90° F to 95°F . Write and graph an inequality that repr

NeX [460]

Answer:

Please find attached the required graph of the inequality representing the temperatures yeast will NOT thrive

Step-by-step explanation:

The given parameters are;

The temperature range, y, in which yeast thrives is 90°F ≤ y ≤ 95°F

Therefore, the temperature range, y', in which yeast will not thrive is 90°F > y and y > 95°F

The graph of the inequality that represents the temperature is therefore given as shown in the attached drawing.

Answer:

$\frac{ {y}^{ - 5} }{x {}^{ - 3} } \\$

when x is 2, y is -4

$= \frac{ {( - 4)}^{5} }{ {2}^{ - 3} } \\ \\ = - 1024 \times {2}^{3} \\ = - 1024 \times 8 \\ = - 8192$
