8am : -14F
noon : -14+10 = -4F
increase between noon and 4 is 2*10 =20
4 pm: -4F + 20 = 16F
temperature at 4 pm is 16F
Answer:
Step-by-step explanation:
- Slope
- where y2=1 , y1=6 , x2=4 , x1=8.
Answer:
yes
Step-by-step explanation: brainly
Slope equation: y2-y1 over x2-x1
3-0 over 3-0 = 1
to get the perpendicular slope of a line, you must use the negative reciprocal therefore, the slope of a line that is perpendicular to k is equal to -1
Answer:
False
Step-by-step explanation:
2x - y = 0
-2x + 2y = 9
Add the equations.
y = 9
(3, 6) is not a solution because in the solution, y = 9.
Answer: False
