Answer:
No.
Step-by-step explanation:
Note that the point:
(x , y) = (2 , 4) -> In which x = 2, and y = 4. Plug in the corresponding numbers to the corresponding variables:
y = 3x
(4) = 3(2)
4 = 3 * 2
4 ≠ 6
Point (2 , 4) does NOT satisfy the equation.

The answer will be B; this is because the cost of each notebook is equivalent to 1.6, or is less than or equal to $56 as we are currently unsure of the value of n (number of notebooks) which means it may cost exactly $56 or less than that as she only has $56 to buy the notebooks to donate to her school
Answer:
32 daffodils bulbs and 28 crocus bulbs
Step-by-step explanation:
Assuming 'x' as Crocus and 'y' as daffodil. Now we'll form equations.
-> for 60 small flowering bulbs
x+y=60
x=60-y --->eq(1)
->Crocus bulbs cost $0.25 each and daffodil bulbs cost $0.65 each with the budget $27.80
0.25x + 0.65y = 27.80 -->eq(2)
Next is to substitute x=60-y in eq(2)
(2)=>0.25(60-y) + 0.65y = 27.80
15 - 0.25y + 0.65y = 27.80
0.4y = 12.8
y = 12.8/ 0.4
y= 32 daffodil bulbs
Now, plugging the value of y in eq(1)
(1)=>x=60-32
x= 28
x=28 crocus bulbs
Therefore, you can buy 32 daffodils bulbs and 28 crocus bulbs
Answer:
x^4 +2 +x^-4
Step-by-step explanation:
The square of a binomial is a form worthy of memorization.
(a +b)² = a² +2ab +b²
<h3>Application</h3>
Here, you have a binomial with a=x² and b=1/x². Using these values in the pattern, we have ...
Find slope: (15-15)/(-1-4) = 0/-5 = 0
Y = 0x + b
15 = 0(4) + b, b = 15
Equation: y = 0x + 15
Or... y = 15
