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
Answer:
$7.56
Step-by-step explanation:
They sell it in $2.25 per kg
Hamburger: cost
1 kg : 2.25
3.4 : 7.56
1 x 3.4= 3.4
so, 2.25 x 3.4= 7.56
she should’ve written m-12 as m12
