The coordinates below represent two linear equations. How many solutions does this system of equations have? Line 1 x y –3 6 3 4
Maksim231197 [3]

Answer

A. Many solution

Step by step explanation

Points on line 1 : (-3, 6) and (3, 4)

Points on line 2: (-6, 7) and  (9, 2)

Now let's find the slope of the line 1

Slope formula = \frac{y2 - y1}{x2 - x1}

Slope of line 1 = (4 - 6) / (3 - (-3)

= -2/(3 + 3)

= -2/6

Slope of line 1 = -1/3

The equation of the line y - y 1 = m(x - x1)

y - 6 = -1/3 (x - (-3))

y -6 = -1/3 (x + 3)

y -6 = -1/3x - 1

y = -1/3x + 5

Slope of line 2 = (2 - 7) / (9 -(-6))

= -5/(9 + 6)

= -5/15

Slope of line 2 = -1/3

The equation of line

y - y1 = m(x - x1)

y - 7 = -1/3(x - (-6))

y - 7 = -1/3(x + 6)

y -7 = -1/3 x - 2

y = -1/3 x + 5

The line 1 and line 2 have the same slopes and the same y-intercept. Both are the same equation. Therefore, there will be many solution.

Answer : A. 0 Solution

Thank you.

Solve to find x <br> log (3x+5) to base 5= 2log (1-3x) to base 25
Eduardwww [97]

Answer:

x = -2/ 3

Step-by-step explanation:

in order to cancel out the logs they should have common bases

\mathsf{ log_{5}(3x + 5) = 2 log_{25}(1 - 3x)  }

we can write 25 as 5²

\mathsf{ \implies  log_{5}(3x + 5) =  2 \: log_{ {5}^{2} }(1 - 3x)  }

we know that the reciprocal of the exponents of the bases are multiplied to the log

\mathsf{ \implies  log_{5}(3x + 5) =   \frac{1}{\cancel{2} } \times \cancel{2} \: log_{ 5}(1 - 3x)  }

and now since the logs have common bases

\mathsf{ \implies  \cancel { log_{5}}(3x + 5) = \cancel{ log_{ 5}}(1 - 3x)  }

we're left with

\mathsf{ \implies 3x + 5 = 1 - 3x}

\mathsf{ \implies 9x = -4}

<u>x = -2/ 3</u>

Kobe has collected 750 football cards and 660 baseball cards. He wants to divide them into piles so that each pile has only one
Harrizon [31]

Answer: 30 cards

Step-by-step explanation:

To find the greatest possible number of cards in each pile such that there is the same number of cards in each​ pile we need to find the greatest common factor of 750 and 660.

Using Euclid division method , we have

750=1(660)+90\\\\660=7(90)+30\\\\90=3(30)+0

Hence, the greatest common factor of 750 and 660 = 30

Thus, there will be 30 cards in each pile.
