Answer:
2 is a number and "twice a number" means multiply by 2.
Answer:
Simplify and solve and get x=-5
Step-by-step explanation:
2/3x - 1/2= 1/3 + 5/6x
2/3x - 5/6x= 1/3 + 1/2
-1/6x= 5/6
x=-5
6 is multiplied by 2 1/3 to get to 14. 70 divided by 2 1/3 is 30. The model of the train is 30 inches long.
Step 1
Find the equation of f(x)
we have the points
(-10,-6) and (0,4)
Find the slope m
The function in slope intercept form is equal to
we have
-----> the point (0,4) is the y-intercept
substitute
step 2
Find the equation of g(x)
we have the points
(-2,-6) and (0,4)
Find the slope m
The function in slope intercept form is equal to
we have
-----> the point (0,4) is the y-intercept
substitute
step 3
Find the value of k
we have
-----> equation A
-----> equation B
----> equation C
substitute equation A and equation C in equation B and solve for k
