Step-by-step explanation:
2x + 14 < 4 , you will treat this as if you are solving algebraic equation with equality sign but be mindful not to change the inequality sign to equality sign.
Subtract 14 from both sides of the equation , we have
2x < 4 - 14
2x < - 10
divide both sides by 2
x < -5
you should notice that the inequality sign did not change , this is because we divided by positive 2.
(ii) x - 7 > 3
Add 7 to both side
x > 10
(iii) considering the modulus symbol , it means the function inside the modulus could be either positive or negative , considering the positive aspect first , we have
2x - 3 = 11
2x = 11 + 3
2x = 14
x = 7
then considering the negative aspect , we have
- ( 2x - 3 ) = 11
- 2x + 3 = 11
-2x = 11 -3
-2x = 8
x = -4
Answer:
x=1
Step-by-step explanation:
Distribute 5/8 to x and -1/3 which will result you in 5/8x - 5/24
The equation now looks like this:
5/8x - 5/24= 5/12
Move -5/24 to the other side by adding 5/24 on both sides
5/8x - 5/24 + 5/24 = 5/12+5/24
(Multiply 2 and 5/12 on both the numerator and denominator which will result you to 10/12 add 5/24 which is 15/24)
Result:
5/8x=15/24
Multiply by 8/5 on both sides:
x=1
5x+20+16
the expression is 5x+36
h=-16t^2+148t+30
find the derivative:
h = -32t+148
0 = -32t+148
-32t=-148
t = -148/-32 = 4.625 seconds
h=-16(4.625)^2+148(4.625)+30 = 372.25
height = 372.25 feet, time = 4.63 seconds
