Hey there! :)
Answer:
-1/2.
Step-by-step explanation:
For a line to be perpendicular, the slope must be the negative reciprocal of the original. In this instance:
A line perpendicular to y = 2x + 7 must contain a slope that is the negative reciprocal of 2.
The negative reciprocal of 2 is -1/2. This is the slope of a perpendicular line.

Answer:
a model is an estimate or approximation of a data set. In the real world, there are too many variables to know exactly what will happen. However, if a model is a good fit, then it can be used to make predictions about what will happen. With a useful model, a predicted value should be a good estimate of an observed value.

Answer:
5.5 hours
Step-by-step explanation:
Given that :
Speed of A = 60 kmphr
Speed of B = 80 kmphr
After what time will distance = 770 km
Speed * Time = Distance
Let time = x
Distance A + Distance B = 770
(60 * x) + (80 * x) = 770
60x + 80x = 770
140x = 770
x = 770 / 140
x = 5.5 hours
