Answer:
x=6
Step-by-step explanation:
7x =42
7 7
x=6
Divide 7 on both sides
The standard equation of a line is given by:
y = mx + b
Where,
m: slope of the line
b: intersection with the y axis.
To define the linear function you need to know the value of the constants m and b
Answer:
You need in order to find an equation:
Slope of the line
Cutting point with the y axis
Answer:
A) 46 mph
Step-by-step explanation:
<em>Step 1: To find the speed, you need to find the distance and time to travel between Chicago and Cleveland.</em>
Distance = 354 miles
Time = 9: 50 am to 5: 30 pm
Time = 7 hours 40 minutes
<em>Step 2: Convert time to hours</em>
1 hour = 60 minutes
40 minutes = 60/40 = 2/3 hours
<em>Step 3: Find the speed</em>
Speed = Distance/Time
Speed = 354/7 + 2/3
Speed = 1062/23
Speed = 46.17 miles per hour rounded off to 46 mph
Therefore, A is the correct answer.
