Equations
657-4w=876-7w
Solve for w
w=73
Answer:
the slope of the line is 4
m = 4
y-intercept is -8
y = 4(0) - 8 = 0 - 8 = -8
Answer:
y = -28 ÷ x
Step-by-step explanation:
The standard format of a inversely proportional equation goes by the format of y = k ÷ x. The question asks us to write an equation if y = 7 when x = -4 and y varies inversely with x.
So we substitute the values y = 7 and x = -4 in the equation y = k ÷ x
K = constant, we have to work this out
7 = k ÷ -4
7 × - 4 = k
k = - 4 × 7
k = -28
k = -28 So then we put this back into the original y = k ÷ x to find our final equation which is y = -28 ÷ x
3x(y+5)
= 3xy+15x
