Step-by-step explanation:
Answer:
x =1 for the first problem
and for second question
Step-by-step explanation:
Let's solve your inequality step-by-step.
|2x+5|>0.5
Solve Absolute Value.
|2x+5|>0.5
We know either2x+5>0.5or2x+5<−0.5
2x+5>0.5(Possibility 1)
2x+5−5>0.5−5(Subtract 5 from both sides)
2x>−4.5
2x2>−4.52(Divide both sides by 2)
x>−2.25
2x+5<−0.5(Possibility 2)
2x+5−5<−0.5−5(Subtract 5 from both sides)
2x<−5.5
2x2<−5.52(Divide both sides by 2)
x<−2.75
Answer:
x>−2.25 or x<−2.75
See the attached picture.
The negative sign in front of the 2 makes the graph an upside down U shape.
15y - 9 < 36
15y < 36 + 9
15y < 45
y < 45 ÷ 15
y < 3
Answer:
- 22.5
Step-by-step explanation:
Substitute x = 3 into f(x) and x = 16 into h(x) , then
g(3) - h(16)
= × - 3(3)² - (2
+ 1)
= × - 3(9) - (2(4) + 1)
= × - 27 - (8 + 1)
= - 13.5 - 9
= - 22.5
