Proportional means that if one increases so does the other eg volume of a balloon increases if you heat it - heat is proportional to volume in gases.
Non proportional means that they don't have a similar relationship.
-26
This because 4x+132 =28
I dont know how your answer is negative though
Answer:
- The degree of the polynomial is even.
- The leading coefficient is positive.
- The polynomial has four zeros.
Step-by-step explanation:
As shown at the graph
The polynomial function intersects with x-axis at 4 points and opens up.
So, we can deduce that:
1) The degree of the polynomial is the fourth degree because it have 4 points of intersection with the x-axis
So, The degree of the polynomial is even
2) As the curve opens up ⇒ The leading coefficient is positive
Leading coefficients are the numbers written in front of the variable with the largest exponent.
3) The polynomial has four zeros because it have 4 points of intersection with the x-axis
The zeros of the polynomial are the values of x at which y = 0
Answer:
See attached diagram
Step-by-step explanation:
Graph the solution of the inequality 
First, draw the dotted line 
(dotted because the sign of the inequality is <). Then determine wich part of the coordinate plane should be shaded. Since the origin's coordinates satisfy the inequality, then this point should belong to the region (red part on the diagram).
Graph the solution of the inequality 
First, draw the solid line 
(solid because the sign of the inequality is ≥). Then determine wich part of the coordinate plane should be shaded. Since the origin's coordinates satisfy the inequality, then this point should belong to the region (blue part on the diagram).
The intersection of both regions is the solution of the system of two inequalities.

1 calculator cost £12
120 divided by 10 = 12
now 8 x 12 = £96
8 calculators cost £96
