Normallly people want miles per hour or miles/hour
so divvided 420 by 7 =420/7=60/1=60 miles per hour
Step-by-step explanation:
step 1. when you graph 2 lines they must intersect unless they are parallel (same slope)
step 2. if they intersect then they have one point in common
step 3. that point in common solves both equations
step 4. when a point solves both equations it is called the solution.
Answer:
b=1
Step-by-step explanation:
Let y = f(x),
y = x
For every unit that y increases, x increases by 1 unit. The straight line graph will cut the y-axis at the origin (x = 0 & y = 0), and form 45° with both x-axis and y-axis at the original.
Hope this helps!
Answer:
2/3
Step-by-step explanation:
Given
Model length: 40 cm
Actual length: 60 m
Scale for any model is ratio of model length of object and actual length of object
Therefore scale for problem stated = Model length/Actual length
= 40/60 = 4/6 = 2/3
