x/2 < -1
Solve for x by multiplying both sides by 2:
X <-2
The solution for X is any number less than -2
Four solutions can be:
-3, -4, -5, -6
Answer:
y = 32
Step-by-step explanation:
Given y is directly proportional to x² then the equation relating them is
y = kx² ← k is the constant of proportion
To find k use the condition when x = 3, y = 4.5 , then
4.5 = k × 3² = 9k ( divide both sides by 9 )
0.5 = k
y = 0.5x² ← equation of proportion
When x = 8 , then
y = 0.5 × 8² = 0.5 × 64 = 32
I was actually just learning this. ^-^
To find the intersection, look at the numbers. and see what numbers do both groups have in common.
In this case, we have { 2, 4, 6, 9 } and { 3, 5, 8 }
As you can see, they both have nothing in common. Number wise.
So the answer would be Null.
First you subtract 5 from each side. so its 6x+5=29 -5 -5which then you get 6x=24. You then divide 6 from 24 and you get x=4
