Answer:

$\frac{6}{8} = \frac{y}{16}$

Step-by-step explanation:

rise = y-axis

run = x-axis

$\frac{rise of smaller trinagle}{run of smaller trinagle} = \frac{rise of larger triangle}{run of larger triangle}$

$\frac{6}{8} = \frac{y}{16}$

Write a minor function for the line with the slope of -5 that passes through points (7,3)

Ilia_Sergeevich [38]

The equation of the line is $5x+y-38=0$

Step-by-step explanation:

The slope is $m=-5$

Also, the line passes through the points $(7,3)$

To find a line with slope $m=-5$ that passes through the points $(7,3)$ , let us use the equation of a line with slope that passes through the point is given by $(y-y_{1} )=m(x-x_{1} )$ where m is the slope and $(x_{1} ,y_{1} )$ are the points $(7,3)$ .

Thus, substituting the values in the equation of a line, we get,

$(y-3)=-5(x-7)$

Multiplying the term $(x-7)$ by -5, we get,

$y-3=-5 x+35$

Adding both sides by 5x,

$5x+y-3=35$

Subtracting 35 from both sides of the equation,

$5x+y-38=0$

Thus, the equation of the line is $5x+y-38=0$

Zack has been planting young trees in his garden. The maple tree that is 42 inches tall is growing 1 inch per month, whereas the

kolezko [41]

In 16 months, two trees will be of same height

The trees will be of 58 inches tall

<em><u>Solution:</u></em>

Let "x" be the number of months

<em><u>The maple tree that is 42 inches tall is growing 1 inch per month</u></em>

Thus, equation for maple tree is given as:

Maple tree : 42 + 1 inch (number of months)

Maple tree : 42 + x ------- eqn 1

<em><u>The oak tree that is 10 inches tall is growing 3 inches per month</u></em>

Thus, equation for oak tree is given as:

Oak tree : 10 + 3 inch (number of months)

Oak tree : 10 + 3x -------- eqn 1

<em><u>For two two trees to be equal in height, equate eqn 1 and eqn 2</u></em>

$42 + x = 10 + 3x\\\\3x - x = 42 - 10\\\\2x = 32\\\\x = 16$

Thus, in 16 months, two trees will be of same height

<em><u>What will that height be?</u></em>

Substitute x = 16 in any one eqn

$10+3x = 10 + 3(16) = 10+48 = 58$

Thus the trees will be of 58 inches tall
