Check the picture below, y = 0 when that happens
bear in mind the square root would give us a +/- roots, however, since this is seconds, a negative unit would be unfeasible, thus we only used the positive root from it.
2x - 3 < 11 or 8x -10 < 82: <span>X < 23/2
<span>
Part 1</span>
</span>2x-3<11
Add 3 both sides
2x-3+3<11+3
Refine
2x<14
Divide by 2 on both sides
2x / 2 / 14 / 2
Refine
x < 7
<span>
Part 2</span>
8x-10<82
Add 10 to both sides
8x-10+10<82+10
Refine
8x<92
Divide by 8
8x / 8 / 92 / 8
Refine
x < 23 / 2
Answer:
Option A is correct answer.
Step-by-step explanation:
An equation is having two sides equal. It has an = sign in it.
So, Option A 2y+7 = 9 is an equation as it has = sign in it. So, it is correct option.
All other options do not have = sign in them so, they are not equations.
Answer:
15
Step-by-step explanation:
15 is the smallest while the rest are seemingly close
Answer:
s = -1
Step-by-step explanation:
7 = -10s - 3
==> add 3 to both sides
10 = -10s
==> divide both sides by -10
-1 = s
