Answer:
endpoints (4,5)
Step-by-step explanation:
endpoints = (2+6/2,7+3/2)
= (8/2,10/2)
= (4,5)
Answer:
x = - 36
Step-by-step explanation:
Given that y varies inversely as x then the equation relating them is
y = ← k is the constant of variation
To find k use the condition y = 27 when x = 12, then
k = yx = 27 × 12 = 324, thus
y = ← is the equation of variation
When y = - 9, then
- 9 = ( multiply both sides by x )
- 9x = 324 ( divide both sides by - 9 )
x = - 36
1.2 is a whole number plus 0.2, we can say 10 + 2 = 12 over 10
12/10 in simplest form is 6/5
Answer: f(3) = 23
Step-by-step explanation:
Put 3 where x is in the expression for f(x) and do the arithmetic.
... f(3) = 2·3^2 +5√(3-2)
... f(3) = 18 + 5 = 23
