Answer:

d=1

Step-by-step explanation:

Move 7 to the other side by subtracting 7 on both sides:

2d+7-7=9-7

The equation now looks like this:

2d=2

Divide 2 on both sides:

2d/2=2/2

The equation now looks like this:

d=1 which is the answer

Help plz will be marked brainlyist

Answer:

Not proportional

Step-by-step explanation:

If x and y are proportional then the equation relating them is

y = kx ← k is the constant of proportionality

To determine if x and y are in proportion then k must be equal for all ordered pairs, that is

k = $\frac{y}{x}$

(2, 0) k = $\frac{0}{2}$ = 0

(4, 2) → k = $\frac{2}{4}$ = $\frac{1}{2}$

(6, 4) → k = $\frac{4}{6}$ = $\frac{2}{3}$

(8, 6) → k = $\frac{6}{8}$ = $\frac{3}{4}$

Since k is not constant for all values then not in proportion
