Answer:
6/5
Step-by-step explanation:
Put 1 where x is and solve.
3·1 -5y = -3
-5y = -6 . . . . . subtract 3
y = 6/5 . . . . . . divide by -5
The value of y is 6/5 when x = 1.
Answer:
see below
Step-by-step explanation:
x ≤ 3
There is a closed circle at 3 because of the equals sign
the lines goes to the left since it is less than
x < 3
There is a open circle at 3 because there is no equals sign
the lines goes to the left since it is less than
The horizontal line has equation 
. The line is solid, and everything below it is shaded, which translates to the inequality 
. (so not B nor D)
The dashed line must have equation 
. Because it's dashed, the inequality is strict. Pick any point in the shaded region, (0, 0) for instance, and compare both sides of this equation. (0, 0) means both 
and 
, so on the left side we have 0, and on the right we have -1. 0 > -1, so the inequality must be 
.
This means the answer is A.
Answer:
100/π cm
Step-by-step explanation:
Volume of a cylinder = πr²h
Volume = 10,000cm³
Radius = 10cm
The formula for the height of a cylinder is obtained as:
V = πr²h
h = V/ πr²
h = 10000 /π × 10²
h = 10000 /π × 100
h = 100/π cm
The height of the cylinder in terms of π = 100/π cm
When u find the volume , u multiply the length and width and height together
