Answer:
Hey!
Step-by-step explanation:
x < 4 Is your answer.. Here is the graph :)
Your answer for the second one is x > 3
Graph is also down below :)
Hope this helps!
Answer:
9x^2 -2x+8
Step-by-step explanation:
( 9x^2 -5x) - ( -3x -8)
Distribute the minus sign
( 9x^2 -5x) +3x +8
Combine like terms
9x^2 -2x+8
The x^2 should be positive and you have it as negative
Answer:
1) B- Substitution
2) C- Elimination
3) A- Graphing
Step-by-step explanation:
1)
x+3y=7
5x+11y=3
x = 7 - 3y
Plug this x into the second equation and solve for y first
2)
5x-3y=3 --> (1)
2x+7y=6 --> (2)
Since making any variable the subject would involve fractions, it's better to go for elimination
7(1) + 3(2)
would eliminate y
3)
While comparing cost and adjusting choices, a graph is a better approach because all the possibilities are right in front
Answer:
$933.3
Step-by-step explanation:
Given data
Principal= $900
Rate= 7.55%
Time= 180 days>>> 6months>>> 0.5 years
Say the account is on a compound interest plan
A= P(1+r)^t
substitute
A= 900(1+0.0755)^0.5
A= 900(1.0755)^0.5
A= 900*1.037
A= $933.3
Hence the teacher will withdraw $933.3 on a compound interest investment after 6 months
