Answer:

$\sf -\dfrac{1}{36}$

Explanation:

$\rightarrow \sf -\dfrac{7}{9} -(-\dfrac{5}{12} )+\dfrac{1}{3}$

<u>remove parenthesis</u>

$\rightarrow \sf -\dfrac{7}{9} +\dfrac{5}{12} +\dfrac{1}{3}$

<u>all the denominators has a common multiple of 108</u>

$\rightarrow \sf -\dfrac{7(12)}{108} +\dfrac{5(9)}{108} +\dfrac{1(36)}{108}$

<u>simplify</u>

$\rightarrow \sf \dfrac{-84}{108} +\dfrac{45}{108} +\dfrac{36}{108}$

<u>join the fractions</u>

$\rightarrow \sf \dfrac{-84+45+36}{108}$

<u>simplify</u>

$\rightarrow \sf \dfrac{-3}{108}$

<u>simplify</u>

$\rightarrow \sf -\dfrac{1}{108}$

Match the equation below with the following graph.

Lemur [1.5K]

Answer:

2x+4

Step-by-step explanation:

The equation of the line in point-slope form is expressed as;

y - y0 = m(x-x0)

Using the coordinates (0,4) and (-2, 0)

Slope = 0-4/-2-0

slope = -4/-2

slope = 2

Substitute m = 2 and the point (0,4) into the formula;

y - 4 = 2(x-0)

y - 4 = 2x

since y = 4 + 2x

y = 2(x+2)

Hence the required equation is 2x+4

Tickets to a school play are $4.50 for an adult and $3.00 for a student. If 300 tickets are sold and $1087.50 collected, how man

Kryger [21]

Answer:

<h2>125 tickets for an adult</h2><h2>and 175 tickets for a student</h2>

Step-by-step explanation:

$a-\text{number of the tickets for an adult}\\s-\text{number of the tickets for a student}\\\\(1)\qquad a+s=300\\(2)\qquad4.5a+3s=1087.5\\------------\\(1)\\a+s=300\qquad\text{subtstitute}\ s\ \text{from both sides}\\a=300-s\\\\\text{Put it to (2):}\\\\4.5(300-s)+3s=1087.5\qquad\text{use distributive property}\\\\(4.5)(300)+(4.5)(-s)+3s=1087.5\\\\1350-4.5s+3s=1087.5\qquad\text{subtract 1350 from both sides}\\\\-1.5s=-262.5\qquad\text{divide both sides by (-1.5)}\\\\\boxed{s=175}$

$\text{Put the value of}\ s\ \text{to (1):}\\\\a=300-175\\\\\boxed{a=125}$

Can you find the rate of change for the following function: -6x + 3y =9?

IgorC [24]

Answer:

The general rate of change can be found by using the difference quotient formula. To find the average rate of change over an interval, enter a function with an interval:

f ( x ) = x ^2 , [ 2 , 3 ]

The rate of Change is 2
