Given the equation 4x + 2y = 9, which equation below would cause an inconsistent-independent system?. . 6x + 12y = 13. . 2x + y
ankoles [38]
An "inconsistent" system means that there will be no shared point between the two lines. This can happen when the two lines are parallel. To determine which one of the equations would cause this, simply compare the slopes of both equations and see which ones match.

The given equation 4x + 2y = 9 has a slope, m = -2

Among the choices, the equation with the same slope is 2x + y = -6.

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

A mountain climber explored a cliff that is 225 yards high in 5 equal descents. How many yards was one descent?
Montano1993 [528]
So if the cliff is 225 yard in height and he want to make it down in 5 equall decents
that means that each dessent is 1/5 of 225 or 225/5
225=125 times 5 so if you divied 225 by 5 then you get 125
so each dessent is 125 yards
