Is y=x^2-6 a linear function and why
jarptica [38.1K]

Answer:

No.

Step-by-step explanation:

No, y=x²-6 is not a linear function.

This is because all linear functions have the highest exponent of 1. Anything equation that has a variable raised to a power other than 1 is not linear.

The equation provided as the highest exponent of 2. Thus, it's not linear.

From the provided graph, we can also see that this is quadratic instead of linear. The graph is a parabola instead of a line.

A circle has a sector with area 27 and central angle of 120
Alex_Xolod [135]

Answer:

81π

Step-by-step explanation:

-The sum of central angles in a  circle add up to 360°.

-Let x be the area of the circle.

-Given the area of a 120° is 27π, the circles area can be calculated as:

A=27\pi\\\\120\textdegree=27\pi\\360\textdegree=x\\\\\therefore x=\frac{360\textdegree\times 27\pi}{120\textdegree}\\\\=3\times 27\pi\\\\=81\pi

Hence, the area of the circle is 81π

Please help STRUGGLING with math few math questions! Ty
-BARSIC- [3]

Question 1:


F(x) and g(x) are like variables, just plug into the equation.


f(x) + g(x) = (x + 6) + (12x - 7)


x+6+12x-7 = 13x-1


Question 2: f(3) + g(-1)


You plug in the x-values into the equation, and then take the answer and add them together.


f(3) = 3+4

g(-1) = 12(-1)-6


f(3) = 7

g(-1) = -18


7 + (-18) = -11


Question 3:


This is similar to question 1, plug in the variables and simplify.


9x - (7x+3)


Remember to distribute the "-"


9x - 7x - 3

2x - 3

If Log x (1 / 8) = - 3 / 2, then x is equal to.<br><br> A. - 4<br> B. 4<br> C. 1 / 4<br> D: 0
Softa [21]

log_{x}(1/8)=-3/2

This is equal to...

x^{-3/2}=1/8

We want "x" so we need to isolate it using laws of exponents...

x^{(-1)(3/2)}=1/8

x^{3/2}=8 because x^{-a}=1/x^{a}

x=\sqrt[3]{8^{2}} because x^{a/b}=\sqrt[b]{x^{a}}

x = 4

answer: B
