Answer:
y = - 3
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition that y = - 1 when x = 3, thus
- 1 = 3k ( divide both sides by 3 )
- = k
y = - x ← equation of variation
When x = 9, then
y = - × 9 = - 3

If is a factor of the polynomial, it means that
is a root of the polynomial.
In fact, if a polynomial has a root
(i.e.
), then the polynomial is divisible by
In your case, you know that the polynomial is divisible by , so
is a solution.
Let's evaluate and set it to zero:
We can check the answer: if the polynomial becomes
And we're claiming that is a root of this polynomial:
Answer:
c
Step-by-step explanation:
Since the figures are similar then the ratios of corresponding sides are equal, that is
=
, substitute values
=
( cross- multiply )
10YZ = 230 ( divide both sides by 10 )
YZ = 23 → c
