Minus the 21 from the other side of the equation making it 7x=-21 then u divide the 7 from the x to the -21 resulting in x=-3
Answer:
A
Step-by-step explanation:
A graph that represents a proportional relationship usually has the line cutting through the line of origin (0, 0).
The graph in option A does not have the line passing through the point of origin (0, 0), therefore, it does not represent a proportional relationship.
For an equation that represents a proportional relationship, it is written in the form of y = kx
Where, k is the constant of proportionality.
Therefore, the two equations given represents a proportional relationship.
First plug in the equations, then simplify/cancel out terms until you get the answer
The answer to this question is 1.88888888889 or rounded to 2.0
Answer:
10
Step-by-step explanation:
X = -1 so, we have:
3·1² + 1
3² + 1
9 + 1
