Answer:
y = 3
Step-by-step explanation:
5y + 6 +3y = 30
5y + 3y = 8y
8y + 6 = 30
-6 -6
8y = 24
24 / 8 = 3
y = 3
Answer:
I think your functions are 
,
and 
If yes then then the third function which is .
Step-by-step explanation:
The function 
where c is a constant has
Domain : 
Range : ( 0 , ∞ )
The above range is irrespective of the value of c.
I have attached the graph of each of the function, you can look at it for visualization.
- <em> ⇒ </em>This function is same as so its range is <em>( 0 , ∞ )</em>.
- <em> ⇒ </em>If we double each value of the function
, which has range ( 0 , ∞ ), but still the value of extremes won't change as 0*2=0 and ∞*2=∞. Therefore the range remains as <em>( 0 , ∞ )</em>.
- <em></em> ⇒ If we add 2 to each value of the function , which has range ( 0 , ∞ ), the lower limit will change as 0+2=2 but the upper limit will be same as ∞. Therefore the range will become as <em>( 2 , ∞ )</em>.
Answer: y=-4x+11
Step-by-step explanation:
1. use formula y=mx+b
2. find the slope
3. plug in one of the points to find y int
Answer:
23.24
Step-by-step explanation:
If the width is 3.4, the radius is 1.7.
7.2-1.7=5.5
Rectangle = 5.5x3.4=18.7
Half circle = 1/2x3.14x1.7²=4.5373
18.7+4.5373=23.2373
Answer:
-16
Step-by-step explanation:
You start with -8 and then subtract another 8.
Or, put differently, you start with -8 and then add -8.
But that's the same thing.
So a + -b is a - b.
