Answer:
3a+6+5/(a+2)
Step-by-step explanation:
To do this you replace x with a+2, meaning that 3x+5/x turns into 3(a+2)+5/a+2. Simplified this is 3a+6+5/(a+2)
Answer:
2nd answer option
Step-by-step explanation:
the domain is the interval or set of valid x values. the range is the same for valid y values.
so, what is the smallest x value we see in the functional graph ?
x = 0
there is no functional value for any x smaller than that.
and then the function goes on and on to the right in all eternity. that means it goes to infinity.
so, domain = [0, infinity)
please consider the round bracket at the end, because "infinity" is not a number.
now for the range and the y values.
in this case I start to ask for the largest y value.
y = 4
for no x value do we get a larger y value.
but it goes down and down in all eternity, going also to infinity, but -infinity (down is negative for y).
so, the range = (-infinity, 4]
"-infinity" is also not a number and therefore not included (hence the round bracket).
Answer:
34
Step-by-step explanation:
You can solve this problem by finding the volume of the candle first. The formula for rectangular prism is multiplying all three of its dimension. In this case, you would multiply 3, 10, and 4 together to get 120 cm^3. Assuming the question meant "the company used 4080 cm^3 of wax", divide 4080 by 120 to see the number of candles the company made, which is 34.
Answer:
Step-by-step explanation:
step 1
Find the area of the garden space
First convert mixed number to an improper fraction
step 2
Find how much more land Farmer Jack needs to plant the rest of his corn
Q=2p+1
subsitute 2p+1 for q in other eqaution
4p+2q=8
4p+2(2p+1)=8
4p+4p+2=8
8p+2=8
minus 2 both sides
8p=6
divide both sides by 8
p=6/8
p=3/4
sub back
q=2p+1
q=2(3/4)+1
q=6/4+1
q=3/2+1
q=3/2+2/2
q=5/2
p=3/4
q=5/2
