Answer:
y = - 2
Step-by-step explanation:
Answer:
y = -51 ÷ 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 = -3 when x = 17 and y varies inversely with x.
So we substitute the values y = -3 and x = 17 in the equation y = k ÷ x
K = constant, we have to work this out
-3 = k ÷ 17
-3 × 17 = k
k = -3 × 17
k = -51
k = -51 So then we put this back into the original y = k ÷ x to find our final equation which is y = -51 ÷ x
7q^2 - 28 = 0
7q^2 = 28
q^2 = 4
q = +/-2
solution set is {-2,2}
Answer:
Step-by-step explanation:
An equation is 5p + 2 = 18.5.
The 1950 population was approximately 3.3 million.
Step-by-step explanation:
If p million was the population in 1950 the equation is:
5p + 2 = 18.5
5p = 16.5
p = 16.5 / 5
p = 3.3 million.
