Simply the expression which is 30
Answer:
1, 2, 3
Step-by-step explanation:
solve the inequality by dividing both sides by 2, hence
n ≤ 3
3 = 3 and 1, 2 < 3
hence 1, 2 and 3 all make the inequality true
Answer:
The graph in the attached figure
Step-by-step explanation:
we have

Isolate the variable y
subtract x both sides

Divide by 2 both sides

The solution of the inequality is the shaded area above the dashed line

The slope of the dashed line is negative
The y-intercept of the dashed line is (0,2)
The x-intercept of the dashed line is (4,0)
therefore
The graph in the attached figure
D = 122 - 72
d = 50
180 - (50 + 72)
= 180 - 122
= 58
e = 180 - (72 + 58)
e = 180 - 130
e = 50
answer
d = 50
e = 50
