Answer:
x ≥5 or 5 ≤x
Step-by-step explanation:
2x ≤ 5x - 15
Subtract 5x from each side
2x-5x ≤ -15
-3x ≤-15
Divide each side by -3, remembering to flip the inequality
-3x/-3 ≥ -15/-3
x ≥5
Check x=10
2*10 ≤5*10 -15
20 ≤50 -15
20 ≤35
True
Answer: %2.1352
(Rounded =%2.1)
Step-by-step explanation:
5.5/5.62=0.978648
1.0 - 0.978648= 0.021352
(Move the decimal over 2 places to the right to convert to percent)
002.1352

(Rounded =%2.1)
3(y+4)-3=y+(y+5)
3y+9=2y+5
1y+9=5
1y=-4
y=-4

Step-by-step explanation:
Answer:
f(-8) = -18
Step-by-step explanation:
given :
f(x) = 2(x – 3) + 4
to find f(-8), simply substitute x= -8 into the function:
f(x) = 2(x – 3) + 4
f(-8) = 2[(-8) – 3] + 4
= 2[-8 – 3] + 4
= 2[-11] + 4
= -22+4
= -18
