Answer:
3y(2 - 9x + 12y)
Step-by-step explanation:
Part A:
The GCF of 6, 3, 24, and 12 is 3:
so 3(2y - xy - 8xy + 12)
= 3(2y - 9xy + 12)
Also y is also common so:
= 3y(2 - 9x + 12y)
Part B:
3y(2 - 9x + 12y)
Step-by-step explanation:
Let say
e=number of english teachers
m=number of math teachers
3 more english tahn math
e=m+3
ratio if e to m is 6:5
e:m=6:5
e/m=6/5
e=m+3
(m+3)/m=6/5
times 5m both sides
5(m+3)=6m
5m+15=6m
minus 5m both sides
15=m
e=m+3
e=15+3
e=18

Answer:
Both points do not lie on the same line
Step-by-step explanation:
<em>There's no drop down to select from. However, I'll answer the question based on whether Ernie's conclusion is correct or not.</em>
Given
Point 1:
(-1,4) and (0,0)
Slope: m = -4
Point 1:
(2,7) and (3,3)
Slope: m = -4
To determine if this conclusion is right or wrong; first, we need to determine the equation of both points using:
For Point 1
---
---
Slope:
becomes
Add 4 to both sides
For Point 2:
---
---
Slope:
becomes
Add 7 to both sides
Comparing both equations:
and
Both expressions are not equal.
<em></em>
<em>Hence, both points do not lie on the same line</em>
