Answer:
Step-by-step explanation:
A) When the first equation is multiplied by 5 and the second equation by –6 ,
the equations become,
35x + 60y=54
-30x - 60y=60
Hence we can eliminate y by adding the equation.
B) When the first equation is multiplied by -5 and the second equation by 6 ,
the equations become,
-35x - 60y=54
30x + 60y=60
Hence we can eliminate y by adding the equation.
C) When the first equation is multiplied by -5 and the second equation by 7,
the equations become,
-35x - 60y=54
35x - 70y=60
Hence we can eliminate x by adding the equation.
D) When the first equation is multiplied by 5 and the second equation by -7,
the equations become,
35x + 60y=54
-35x - 70y=60
Hence we can eliminate x by adding the equation.
E) When the first equation is multiplied by -5 and the second equation by 10,
the equations become,
-35x - 60y=54
50x - 100y=60
Hence we can not eliminate x by adding the equation.
By using sin you can find BD. Sin is the opposite side/ hypotenuse. This can be simplified to BD = opposite (4) divided by sin(27). 27 is the angle.
We need the ordered pairs to choose an answer, but if you want to do it yourself you plug in the x and y values (x,y) and test to see if the equation is true, and equals -19.
If we look at the series, one third of the current term gives the numerical value of the next term.
If we need to express it algebraically, we can write the following equation.
Therefore, our common multiplier can be found as follows. Because this sequence is a geometric sequence.
In geometric sequences, any term can be written in terms of the first term. Below is an example.
Since we know the numerical values of the first term and the common factor of the series, we can easily find the seventh term.
<span> The </span>associative property<span> states that you can add or multiply regardless of how the numbers are grouped. By"grouped" we mean 'how you use parenthesis'. In other words, if you are adding or multiplying it does not matter where you put the parenthesis</span>
