Answer:
x=0.625
Step-by-step explanation:
-(-2x+1)=9-14x
distribute:
2x-1=9-14x
add 1 to both sides
2x = 10-14x
add 14x to both sides
16x=10
divide by 16 to isolate x
x = 0.625
check:
-(-2(0.625)+1) = 9-14(0.625)
0.25 = 0.25

Answer:
The number of slices of salami and the number of calories are not proportional
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
Let
x -----> the number of slices of salami
y ----> the number of calories
Find out the value of the constant of proportionality k
For (1,66) -----> ---->
For (2,96) -----> ---->
For (3,126) -----> ---->
For (4,156) -----> ---->
The values of k are different
therefore
The number of slices of salami and the number of calories are not proportional
