Answer:
(0,7)
Step-by-step explanation:
The range of a function on a graph can basically be described as the vertical bounds for that graph. Since the graph does not go below y=0 and does not go above y=7, you can say that the range is (0,7).
Answer:
x = 4 is the solution
Step-by-step explanation:
given = x ( square both sides )
x + 12 = x² ( rearrange into standard form )
x² - x - 12 = 0 ← in standard form
(x - 4 )(x + 3 ) = 0 ← in factored form
equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
x + 3 = 0 ⇒ x = - 3
Insert these values into the original equation, and if both sides are equal, and those are the solutions.
x = 4 : = = 4 = x ← correct
x = - 3 : = = 3 ≠ - 3 ← false
the answer is x = 4
The answer is a.
The smallest unit price has the best deal.
Find the unit price by dividing the price by the ounces.
a) $9.13 ÷ 39 = <span>0.2341025641 = $0.23</span>
b) $3.56 ÷ 14 = 0.25428571428 = $0.25
c) $6.12 ÷ 24 = 0.255 = $0.26
d) $4.98 ÷ 18 = 0.27666666666 = $0.28
D. Only has 3 numbers in the 5-9 range, while the histogram shows 4. Hope this helps :)
Answer:
1) $283.50
2) 65.21 meters.
Step-by-step explanation:
Part 1)
We know that a spool of ribbon holds 6.75 meters.
A craft club buys 21 spools.
So, the total length of ribbon bought is:
Each meter costs $2. So, the total cost will be:
Part 2)
A spool holds 6.75 meters.
We bought 21 of them, so that total length we have is 141.75 meters.
The club used 76.54 meters.
So, the amount of ribbon that is left is represented by:
Subtract:
So, 65.21 meters of ribbon will be left.
