Answer:
She did not represent the two original factors correctly on the headers.
Step-by-step explanation:
Adi algebra tiles representation is shown in the figure attached.
She made a mistake when she represented -2x-1 with two negative tiles in the top header
, so, the representation in the header is not correct.
Answer:
Step-by-step explanation:
If two variables are directly proportional, it means that an increase in the value of one variable would cause a corresponding increase in the other variable.
Given that y varies directly with x, if we introduce a constant of proportionality, k, the expression becomes
y = kx
If y = 8 when x = 3, then
8 = 3k
k = 3/8
Therefore, the direct variation equation that relates x and y is
y = 3x/8
When x = 12, then
y = 3 × 12/8
y = 4.5
