Answer:
± 3
Step-by-step explanation:
let n be the number then the number squared is n² , so
6n² = 54 ( divide both sides by 6 )
n² = 9 ( take the square root of both sides )
n = ± = ± 3
That is the number is 3 or - 3
Answer:
Step-by-step explanation:
Given question is incomplete; here is the complete question,
Here is an equation that represents a function: 72x + 12y = 60.
Select all the different equations that describe the same function.
A). 120y + 720x = 600
B). y = 5 - 6x
C). 2y + 12x = 10
D). y = 5 + 6x
E).
F). 7x + 2y = 6
G).
Option A.
720x + 120y = 600
72x + 12y = 60
True.
Option B.
y = 5 - 6x
6x + y = 5
12(6x + y) = 12(5)
72x + 12y = 60
True
Option C.
2y = 12x + 10
-12x + 2y = 10
-6(-12x + 2y) = -6(10)
72x - 12y = -60
False
Option D.
y = 5 + 6x
-6x + y = 5
-12(-6x + y) = -12(5)
72x - 12y = -60
False.
Option E.
72x = 60 - 12y
72x + 12y = 60
True.
Option F.
7x + 2y = 6
6(7x + 2y) = 6(6)
42x + 12y = 36
False
Option G
72x = 60 + 12y
72x - 12y = 60
False
Options A, B and E are the correct options.
The answer is A. because the first part shows the ratio 3:2 and the other 2 shows equivalent ratios.
Hello,
As (2,-4) is the vertex, the parabola is y=k(x-2)²-4
As (3,-1,) is a point of the parabola:
-1=k*(3-2)²-4
==> k=3y=3(x-2)²-4 so, coefficient of x² is 3.
