4x - 2(3x - 9)....distribute the 2 thru the parenthesis
4x - 6x + 18....combine like terms
-2x + 18 <===
Answer:
1: -3
2: She gives him $3 per week
3: 18
4: How much money she initially borrowed
5: y = -3x + 18
Answer:
see below
Step-by-step explanation:
2x ≥ 4
Divide by 2
2x/2 ≥ 4/2
x ≥ 2
-x+7<-6
Subtract 7 from each side
-x+7-7<-6-7
-x < -13
Divide each side by -1, remembering to flip the inequality
x > 13
y>-x+3
This is a line with slope -1 and y intercept 3
This is a dotted line since there is no equals sign and graph above
