ANSWER:
4 ( 2x - 3y + 8 )
8x - 12y + 32 in factorised form is equivalent to:
4 ( 2x - 3y + 8 ).
STEP-BY-STEP EXPLANATION:
8x - 12y + 32 in factorised form is ~
= 8x - 12y + 32
GCF = 4
THEREFORE:
= 4 ( 2x - 3y + 8 )
Answer:
The coefficient matrix is singular, so there are no solutions or infinite solutions.
The two equations in the linear system are the same, so there are infinite solutions.
Yes, there are solutions
Step-by-step explanation:
26.8% of examinees will score between 600 and 700.
This question is based on z score concept.
A Z-score is a numerical measurement that describes a value's relationship to the mean of a group of values. Z-score is measured in terms of standard deviations from the mean. If a Z-score is 0, it indicates that the data point's score is identical to the mean score.

where:
μ is the mean
σ is the standard deviation of the population
Given:
μ = 560
σ = 90
For
600≤ X≤700
for x = 700
Z score =x - μ/σ
=(700 - 560)/90
= 1.55556
P-value from Z-Table:
P(560<x<700) = P(x<700) - 0.5 = 0.44009
for x = 600
Z score =x - μ/σ
=(600 - 560)/90
= 0.44444
P-value from Z-Table:
P(560<x<600) = P(x<600) - 0.5 = 0.17164
∴ P(600<x<700) = P(560<x<700) - P(560<x<600)
= 0.44009 - 0.17164
=0.26845
∴26.8% percentage of examinees will score between 600 and 700.

A-2b=-10
add 2b on both sides
a=2b-10
add 10 to both sides
a+10=2b
divide both sides by 2
a/2+10/2=a/2+5=b
b=5+a/2
