Answer: x=3, See the graph below

Step-by-step explanation:

SINCE THE QUESTION ASK FOR GRAPHING

See the graph below

-------------------------------------------------------------------

I AM ALSO GOING TO SHOW A SECOND WAY WITHOUT GRAPH FOR EXTRA

Given

y=6

y=3x-3

Use substitution (Substituting the value of y)

3x-3=6

Add 3 on both sides

3x-3+3=6+3

3x=9

Divide 3 on both sides

3x/3=9/3

x=3

Hope this helps!! :)

If y2 = x3 + 2, which statement is true? The equation is a function at all values of x. The equation is not a function. The equa

tatyana61 [14]

Answer:

The equation is not a function.

Step-by-step explanation:

We are given that

$y^2=x^3+2$

$y=\pm\sqrt{x^3+2}$

Function: It is mapping between the values of two sets A and B.

Each element of A has unique value in set B.

By definition of function

In given function

y has no unique value for each value of x.

Substitute x=0

$y=\pm \sqrt{0+2}=\pm \sqrt 2$

Hence, it is not a function.

Find the length of AB. A 0140 AB = [?] 140° 8 m B Round your answer to the nearest hundredth.

$\huge{ \mathfrak{ \underline{ Answer} \: \: ✓ }}$

Radius (r) = 8m

Angle made at centre $(\theta)$ = 140°

$\boxed{ \mathrm{length \: \: of \: \: arc = \dfrac{ \theta}{360 \degree} \times 2\pi r}}$

$\dfrac{140}{360} \times 2 \times 3.14 \times 8$

$\dfrac{7}{18} \times 50.24$

$\dfrac{351.64}{18}$

$19.54 \:m$

Explain in 1-2 sentences how you identify

andrezito [222]

Answer:

You can tell because, as x increases/decreases, y increases/decreases at the same rate EACH TIME. This way, no matter how many times the proportions increase OR decrease, the ratio between x and y always stays the same.
