Answer:

<h2>y = 54 ✅</h2>

Step-by-step explanation:

If the two numbers vary directly, we can use a proportion to find the missing value.

36/4 = y/6

4y = 216

Divide by 4

y = 54

Check

36/4 = 54/6

216 = 216 ✅

What will be the linear equation for the shown table?<br><br>​
vladimir1956 [14]

Answer:

y=2x+5

Step-by-step explanation:

To find a linear equation you must find the slope and y intercept to create an equation in y=mx+b form (slope-intercept form)

So slope is = y2-y1 / x2-x1 [2 and 1 are subscripts] so 11-7/3-1 so m=4/2 = 2

Slope = 2, now find b

So using y = mx + b, substitute what you know so 7 = 2(1) + b so b=7-2 = 5

Put it all together y = 2x + 5

If m(x) =x+5/x-1 and n(x) =x-3 which function has the same domain as (m.n)(x)
Travka [436]

Answer:

Step-by-step explanation:

m (x) = (x+ 5) / (x -1)        and     n(x) = x - 3.

m(x) = \dfrac{x+5}{x-1}

Hence

m(n) = \dfrac{n+5}{n-1}

but n is a function and n = x-3. Now, replace value of n on m (n)

(m(n))= \dfrac{(x-3)+5}{(x-3)-1}

simplify it

(m\bullet n)(x) =\dfrac{x+2}{x-4}\\

since (m . n) (x)  is a fraction function, its domain will be all x such that the denominator is NOT 0. That is

x-4\ne 0\rightarrow x\ne 4

among options, only C has the same denominator with (m\bullet n)(x)

Hence their domains are the same.
