How do you factorise 20y plus 45?
To factorise the expression (20y + 45), first identify the greatest common factor (GCF) of the two terms. The GCF of 20 and 45 is 5. You can then factor out 5, resulting in (5(4y + 9)). Thus, the factorised form is (5(4y + 9)).

8x + 20y
How do you solve 8x plus 20y equals -80?
It is a straight line equation that needs to be rearranged into slope-intercept form as follows:- 8x+20y = -80 20y = -8x-80 y = -0.4x-4
How do you graph x2 plus 10x plus y2 plus 20y - 19 equals 0?
x2 + 10x + y2 + 20y - 19 = 0 x2 + 10x + y2 + 20y = 19 Complete the squares on the LHS: x2 + 10x + 25 + y2 + 20y + 100 = 19 + 25 + 100 = 144 Simplify LHS: (x + 5)2 + (y + 10)2 = 122 This is the equation of all points whose distance form the point (-5, -10) is 12 units. That is, the circle with centre (-5, -10) and radius = 12 units.
X equals 5y2-20y plus 15?
x isn't in the calculation so it cant be solved.
What is the GCF or 30y'2 20y'2?
You need at least two terms to find a GCF.
How do you solve 12y-4 equals 7y plus 16?
12y - 4 = 7y + 165y = 20y = 4
What are the points of intersection of the line 3x -y equals 5 with the curve of 2x squared plus y squared equals 129 with key stages of work shown?
If: 3x-y = 5 and 2x2+y2 = 129 Then: x = 5/3+y/3 and so 2(5/3+y/3)2+y2 = 129 => 50+20y+2y2+9y2 = 1161 Therefore: 11y2+20y-1111 = 0 Solving the quadratic equation: y = -11 or y = 101/11 By substitution points of intersection are: (-2, -11) and (52/11, 101/11)
