Answer:
Steven has £90 now
Step-by-step explanation:
Steven has = £1100
After paying for the TV = £1100 - £530
= £570
Now,
After paying for the mortgage = £570 - £480
=£90
Answer:
B
Step-by-step explanation:
The diagram shows four points through which the line of proportional relationship should pass. One of these points has coordinates (8,28).
The line representing proportional relationship is always straight line passing through the origin and has the equation
where k is the coefficient of proportionality.
Substitute coordinates of known point into the equation:
so the coefficient of proportionality is equal to
1) Answer 4.
Explanation.
The number of total roots of a polynomial is the degree of the polynomial. In this case it is 4.
The real, i.e. non-complex roots of a polynomial correspond to the x-intercepts of the graph. Then you can graph the polyomial to see how many real roots it has.
The graph of this polynomial shows that it does not cross or touch the x-axys which means that there are not real roots. Thereafter the 4 roots are complex.
2) The multiplicity of a root is the number of times that the corresponding factor appears in the polynomial. In this case the factor x + 1 appears two times, then - 1 has multiplicity 2.
3) You can either graph the polynomial or factor it.
If you factor it you will find:
x^4 - x^3 - 9x^2+7x+14 = (x +1)(x -2)(x^2 -7).
The there are 4 zeroes or 4 real roots.
