Answer:
The graph of y = 2x+1 will never go through the point (2,3) because the graph is a linear function which means it goes in a straight line. Knowing this, when y = 3, x = 5 this means that the function will never hit (2,3)
A.6
<span>because a coefficient is the numerical constant quantity placed before and multiplying the variable in an algebraic expression. (eg 5x so the coeff is 5)</span><span />
1. Take the two x-axis intersections.
For Q 31 it is:
x = -4 and x = 0
2. Reorganise the previous equations
x +4 = 0 and x = 0
3. Put the x side in brackets
x(x+4)
4. Done

Q 32
x = -1
x = 5
x + 1 = 0
x - 5 = 0
(x+1)(x-5)
5+5= 10
10 time 9b is 90b
10 times -7 is -70
Then 90b-70
