For question 1, just plug in -2 as <em>h.
</em>
<em>
</em>You would get...

</em>Hope this helped! <em>-4, or option 1, is correct!</em><em>

Root: A/2 is the equation
your answer is 1.38
It's the first one because all the y's are the same number. That means that when you graph the chart you would get a horizontal line. Horizontal lines on graphs always have a slope of zero....unlike a verticals slope is undefined.
2x +4y =10x-3y =12
2x +4y =12 -----eq. 1
10x-3y =12 -------eq.2
2x =12 -4y [using eq. 1]
x = (12-4y)/ 2
= 6 -2y
Now, substitute the value of x in eq. 2
10 (6-2y)-3y =10
60 -20y -3y =10
-23 y = 10 -60
y = -50 / -23
y = 50/23
Now, substitute this value of y in any equations given above
10 x-3 (50/23) =12
10x - (150/23)= 12
x= 426/230
The number provided rounded to the nearest tenth is 13.2.
Because the number in the hundreds place is a 4, we round down and keep the tenth at 2.
