Answer:
D. Undefined
Step-by-step explanation:
The slope is the ratio of rise to run. When the line is vertical, the run is zero, so calculating the slope involves division by zero. That makes the slope be <em>undefined</em>.
Answer:0.03
Step-by-step explanation:
25 is 5 times as 5 so here is the answer
Simplif 1/2t to t/2
t/2 + 8 = 5/2t - 10
Simplify 5/2t to 5t/2
t/2 + 8 = 5t/2 - 10
Multiply both sides by 2
t + 16 = 5t - 20
Subtract t from both sides
16 = 5t - 20 - t
Simplify 5t - 20 - t to 4t - 20
16 = 4t - 20
Add 20 to both sides
16 + 20 = 4t
Simplify 16 + 20 to 36
36 = 4t
Divide both sides by 4
36/4 = t
Simplify 36/4 to 9
9 = t
Switch sides
<u>t = 9</u>
Answer:
92°F
