Which of the following systems is equivalent to the given system? 2/3x - y = 2

Based on the given above, the correct answer would be <span>x-30y=100 and 10y=x-20, the first option.
So how do we know that this is the correct option. So, let us check
0.01x - 0.3y = 1 <<multiply both sides by 100 (since there is 2 decimal places after the decimal point
The result for this would be x - 30y = 100 (So this is correct)
Next,
y = 0.1x -2 << multiply both sides by 10 since there are only 2 decimals places after the decimal point
The result would be 10y = x - 20 (So this is correct)
Hope that answer helps</span>

Use the FOIL method to evaluate the expression

In-s [12.5K]

So u multiply each term in the first parentheses by each term in the second parentheses.

√5 √5 + 6√5-3√5 - 3x6
Now you multiply the numbers which will get u:
5+6√5 - 3√5 - 18
Then subtract:
-13 +3√5 that’s your answer

Answer:

$y=-\frac{3}{2}x+1$

Step-by-step explanation:

Slope-intercept form means

$y=mx+c$

where m is given its the slope which is $-\frac{3}{2}$ and we have the coordinates x and y which is (4, -5) and we need to find the value of c which is the y-intercept so we insert all these values into the equation so ,

$y=mx+c$

$-5 = -\frac{3}{2}(4)+c$

$-5=-6+c$

$c=1$

now we know the value of slope which is given $-\frac{3}{2}$ and we found the value of which is 1 so we put these values into our original slope-intercept form equation

$y=mx+c\\\\y=-\frac{3}{2}x+1$
