Answer:
Step-by-step explanation:
The line is parallel to y axis so
slope : undefined
y intercept : the line doesn’t intercept y axis
Equation : x = -6
average speed= total distance/total time taken
60+45= 105miles
1 mile= 1.609
105×1.609= 168.945km
168.945/4
Hence answer = 33.79 km/hr
Step-by-step explanation:
I am prerty sure it is 1/3 because 5 is 1/3 of 15 and 15 is 1/3 of 45
Answer:
All real numbers would be the solution
Step-by-step explanation:
2y - 4x =2 and y = 2x + 1
We solve but placing the value of y into the first equation:
2(2x + 1) - 4x = 2
Next we distribute the 2 through the parenthesis:
4x + 2 - 4x = 2
Now we gather like terms:
2 = 2 ( note the 4x and - 4x cancel out)
Since 2 =2 this tells us that all real numbers would work.
