Answer:
<h2>B. Standard</h2>
Step-by-step explanation:
The point-slope form of an equation of a line:
m - slope
(x₁, y₁) - point
The slope-intercept form of an equation of a line:
m - slope
b - y-intercept
The standard form of an equation of a line:
The general fom of an equation of a line:
We have the equation 3x - 2y = 4 in standard form.
The answer choice which represents the group which makes up the best sample for the researcher's survey as described in the task content is; Choice A; Parents of preschool children.
<h3>Which answer choice best represents a sample for the intended survey by Mrs Greenaway's researcher?</h3>
It follows from the task content that; Mrs. Greenaway has decided to open a new preschool in her town.
The need for a researcher therefore arises from the decision to either open the preschool or not.
Consequently, in a bid to choose a sample, Mrs. Greenaway's researcher must make sure the sample chosen is from the population space.
Therefore, answer choice A represents the correct sample.

Answer:
Step-by-step explanation:
2ab - 4b
Taking 2b as common
2b( a - 2)
Answer:
x = 5 and -6
Step-by-step explanation:
Using the intersecting chord theorem which states that the products of the lengths of the line segments on each chord are equal.
Hence:
let
a = 6, b = 5, c = x+1 and d = x
Therefore, ab = cd
6*5 = x(x+1)
30 = x²+x
x²+x - 30 = 0
x²+ 6x - 5x - 30 = 0
x(x+6) - 5(x+6) =0
(x-5)(x+6) = 0
x-5 =0 and x+6 = 0
x = 5 and -6
