The tables represent two linear functions in a system,

Alenkasestr [34]

Answer:

<h2>(8, -22)</h2>

Step-by-step explanation:

The slope-intercept form of an equation of a line:

$y=mx+b$

m - slope

b - y-intercept

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

First table:

(-4, 26), (0, 10) → b = 10

$m=\dfrac{10-26}{0-(-4)}=\dfrac{-16}{4}=-4$

$\boxed{y=-4x+10}$

Second table:

(-4, 14), (0, 2) → b = 2

$m=\dfrac{2-14}{0-(-4)}=\dfrac{-12}{4}=-3$

$\boxed{y=-3x+2}$

We have the system of equations:

$\left\{\begin{array}{ccc}y=-4x+10&(1)\\y=-3x+2&(2)\end{array}\right\\\\\text{Put (1) to (2):}\\\\-4x+10=-3x+2\qquad\text{subtract 10 from both sides}\\-4x=-3x-8\qquad\text{add 3x to both sides}\\-x=-8\qquad\text{change the signs}\\x=8\\\\\text{Put the value of x to (2):}\\\\y=-3(8)+2\\y=-24+2\\y=-22$

Y is six more than x divided by three <br><br> turn it into an expression (y=mx+b format)

Snowcat [4.5K]

We always start from right side in order of operation in any equation

we can set up equation as

step-1:

x divided by three

we can write as

$=\frac{x}{3}$

step-2:

six more than x divided by three

so, we get

$=\frac{x}{3}+6$

step-3:

y is six more than x divided by three

so, we get

$y=\frac{x}{3}+6$

and this is in y=mx+b form

so, we have

$y=\frac{x}{3}+6$ ...............Answer

Another fairly simple one, pretty much a free Brainliest and 30 points.

Alchen [17]

Answer:

Solution given:

$8\frac{7}{12}-3\frac{1}{3}=\frac{8*12+7}{12}-\frac{3*3+1}{3}$

= $\frac{103}{12}-\frac{10}{3}$

taking lcm

= $\frac{103-10*4}{12}=\frac{63}{12}=\frac{21}{4}=5\frac{1}{4}$
