A. 25 = (.5 * 22) + (2 * x)
B. 25 = (.5 * 22) + (2 * x)
25 = 11 + 2x
14 = 2x
7 = x
C. 7
Answer:
81
Step-by-step explanation:
93-12=81
The equation is y = 63/x
And y = 3 when x=21
Step-by-step explanation:
When y varies inversely with x, The inverse proportion is given by:
y ∝1/x
When the proportionality symbol is removed, a constant of proportionality is introduced

Putting y = 7 and x = 9

So,

Putting x =21

Hence,
The equation is y = 63/x
And y = 3 when x=21

Answer:
A. y = -10x
Step-by-step explanation:
An equation that has a line that passes through the origin (0, 0) is represented in slope intercept form as y = mx
Where, m is the slope.
Therefore,
The equation that represents a graph with a negative slope and passes through the origin would be:
y = -10x
-10 is the slope (m).
