7 0

Answer:

Step-by-step explanation:

(-4,0) ; (-7, -14)

d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}\\\\ =\sqrt{(-7-[-4])^{2}+(-14-0)^{2}}\\\\ =\sqrt{(-7+4)^{2}+(-14)^{2}}\\\\=\sqrt{(-3)^{2}+(-14)^{2}}\\\\=\sqrt{9+196} \\\\=\sqrt{205} \\\\=14.3178

How many solutions does -3x+15=3(5-x) have
S_A_V [24]

Answer:

Infinite solutions

Step-by-step explanation:

So if simplified it would be

-3x+15=15-3x

Which is basically the same thing if arranged

15-3x=15-3x

-3x+15 can also be 15-3x still the same thing as adding 15 to -3x

So since these are equal anything could be used

like try 0

Both get 15

Try 1

Both get 12

Try legit any number

youll get the same results (I would choose 3 positive easy ones, 0,1,2 and 3 negative ones -1,-2,-3)

A tree is 4 m 25 cm high! A pole is 70 cm shorter. How high is the pole? ​
ivanzaharov [21]

-------------------------------------------------------------------------------------------------------------

Answer:  \textsf{3955cm}

-------------------------------------------------------------------------------------------------------------

Given: \textsf{Tree = 4m and 25cm, Pole = 70cm shorter}

Find: \textsf{The height of the pole}

Solution: The first step that we must take is to convert the tree height to centimeters and after doing so we would just subtract 70 cm from that to get the pole height.

<u>Convert to cm</u>

  • \textsf{m = 1000cm}
  • \textsf{4m = (1000cm * 4)}
  • \textsf{4m = 4000cm}

<u>Combine</u>

  • \textsf{4000cm + 25cm}
  • \textsf{4025cm}

<u>Subtract 70 from the tree height</u>

  • \textsf{4025cm - 70cm}
  • \textsf{3955cm}

Using the information from the problem the height of the pole would be 3955cm.
