Answer:
x-intercept - x = 1/2y - 3.15
y-intercept - y = 2x + 6.3
Step-by-step explanation:
For x,
-6x + 3y = 18.9
-6x = -3y + 18.9
x = -3y/-6 + 18.9/-6
x = 1/2y - 3.15
For y,
-6x + 3y = 18.9
3y = 6x + 18.9
y = 6x/3 + 18.9/3
y = 2x + 6.3
Answer:
the answer is 4pi or 12.56637061
Step-by-step explanation:
the arc length equals 2pi x radius ( known angle (120) / 360 which equals 4pi or 12.56637061

The solution to an inequality is represented by the number line. How can this same solution be written using set-builder notation? {x | x > }
Answer:
Step-by-step explanation:
Given an inequality whose solution is represented by the number line attached below.
We observe the following from the number line
There is an open circle at 3, therefore the solution set does not include 3. (We make use of > or < in cases like that)
The arrow is pointed towards the right. All points to the right of 3 are greater than 3, therefore:
The solution in the number line can be written using set-builder notation as:
First, factor out h so the equation can be h(b+r)=25 then divide by b+r so h= 25/b+r
