Answer:y = 15
Step-by-step explanation:
Given y=kx,
where k is a constant
When y=8 and x=2/3, K =?
y=kx
8= k 2/3
K=(3 x8)/2= 24/2 = 12
K=12
Now when x=5/4 y=?
y= kx
y = 12 X 5/4= 60/4
y = 15
7,-1,9 ? I think you have to set the numbers to zero
Answer: 0.5 < x < 16.5.
Step-by-step explanation:
Given: Two sides of triangle: 8.0 units and 8.5 units
Measure of third side = x
According to the triangle's inequality,
- Sum of any two sides > third side. (i)
- Difference between the sides < third side. (ii)
If x is the third side, then
x < 8+8.5 [Using (i)]
i.e. x< 16.5
Also, x > 8.5-8 [Using (ii)]
i.e. x> 0.5
Hence, Range of possible sizes for side x would be 0.5 < x < 16.5.
