What is the elimination to this solution i think its b

Blababa [14]

EXPLANATION:

To get the solution of the simultaneous equation, using the elimination method:

We will have the following steps:

Step 1:

Write the two equations:

$\begin{gathered} y=-\frac{1}{2}x+3 \\ y=-\frac{7}{2}x-3 \end{gathered}$

Step2: Subtract the two equations:

$\begin{gathered} y-y=-\frac{1}{2}x-(-\frac{7}{2}x)+3-(-3) \\ 0=-\frac{1}{2}x+\frac{7}{2}x+6 \\ \end{gathered}$

Step 3: Simplify the expression

$\begin{gathered} 0=3x+6 \\ 3x=-6 \\ x=-\frac{6}{3} \\ x=-2 \end{gathered}$

Step 4: Substitute x=-2 into the formula:

$\begin{gathered} y=-\frac{1}{2}x+3 \\ y=-\frac{1}{2}\times-2+3 \\ y=1+3 \\ y=4 \end{gathered}$

Therefore, the answer is

$(-2,4)$

Thus,

Option B is correct

7x10^6 is _________ x the value of 2x10^4

sashaice [31]

Answer:

350

Step-by-step explanation:

so the first step is to find the values of each of them

7x10^6=7000000

2x10^4=20000

then we divide 7000000 by 20000

7000000/20000=350

so the answer is 350

hope this helps :)
