The eucalyptus is the world's fastest growing tree. It grows an average of 2 1/2 centimeters every day. If a eucalyptus tree is

50 centimeters tall when it is planted, how tall will it be in 5 days?

2.5(5)= 12.5
12.5+ 50= 62.5

Therefore, the eucalyptus tree will be 62.5 cm in 5 days.

Hope this helps!

Given GHI G (4,-3), H (-4,2), and I (2,4), find the perpendicular bisector of HI in standard form.
Olin [163]

Answer:

3x+y=0

Step-by-step explanation:

step 1

Find the slope of segment HI

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

we have

H (-4,2), and I (2,4)

substitute the given points

m=\frac{4-2}{2+4}

m=\frac{2}{6}

simplify

m=\frac{1}{3}

step 2

Find the slope of the perpendicular line to segment HI

we know that

If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)

m_1*m_2=-1

we have

m_1=\frac{1}{3}

so

m_2=-3

step 3

Find the midpoint segment HI

we know that

The formula to calculate the midpoint between two points is equal to

M(\frac{x1+x2}{2},\frac{y1+y2}{2})  

we have

H (-4,2), and I (2,4)

substitute

M(\frac{-4+2}{2},\frac{2+4}{2})

M(-1,3)  

step 4

we know that

The perpendicular bisector of HI is a line perpendicular to HI that passes though the midpoint of HI

Find the equation of the perpendicular bisector of HI in point slope form

y-y1=m(x-x1)

we have

m=-3

M(-1,3)  

substitute

y-3=-3(x+1)

step 5

Convert to slope intercept form

y=mx+b

Isolate the variable y

y-3=-3x-3

y=-3x-3+3

y=-3x

step 6

Convert to standard form

Ax+By=C

where

A is a positive integer

B and C are integers

y=-3x

Adds 3x both sides

3x+y=0

see the attached figure to better understand the problem

Does -3(x-4)= -3x=12 have one solution, many solutions, or no solutions at all?
TEA [102]

Answer:

If the expression is:

-3x + 12 = -3x + 12, infinite solutions

If the expression is:

-3x + 12 = -3x - 12, no solutions

Step-by-step explanation:

Step 1: Distribute

-3x + 12 = 3x = 12

If both lines have the same slope and same y-int, they are the same line and therefore have infinite solutions.

If both lines have the same slope but different y-int, then they are parallel and therefore have no solutions.
