Answer:b=-10.5, a=31.5
Step-by-step explanation: 3b=-a , -3b=a
a+b =21
-3b+b = 21
-2b=21
b=-10.5
a=-3b
a=-3*-10.5=31.5
The slope is 4 so D

The next two terms in the arithmetic progression will be 15 and 21.
Based on the information given, the following can be deduced.
First term = 3
Second term = 9
Common difference = 9 - 3 = 6
The nth term of an arithmetic progression is given as: = a + (n-1)d
Therefore, 3rd term = a + 2d = 3 + 2(6) = 3 + 12 = 15
4th term = a + 3d = 3 + 3(6) = 3 + 18 = 21
The next 2 terms are 15 and 21.

Answer:
f(x) = (x+5)(x-1)(x-3)
Step-by-step explanation:
From the graph, we have that the function intercepts the x-axis at the points x = -5, 1,3
From here, we have
x = -5
x = 1
x = 3
So we have the factors as;
x + 5, x - 1 , x - 3
So what this mean is that we have the function as;
f(x) = (x+5)(x-1)(x-3)
