At a rate 64kilometer per hrs how far will a car travel in Seven and a half hrs?
If they had six bags of cookies and each bag has thirteen cookies, then in total they have a total of seventy-eight cookies. If they've eaten twenty-nine cookies, then they now have forty-nine cookies because 78-29=49.
First change the first equation in to slope-intercept form
y=mx+b<-----slope intercept form
m=slope
b=y-intercept
4y=-x+8
y=1/4x+2<----final slope-intercept form
now, you know there is a point that is (0,2), the y-intercept, so now you calculate the slope.
y2-y2/x2-x1<------slope formula
3-2/0-3
1/-3
-1/3<---slope
so your final equation is
y=(-1/3)x+2
hope this helps! :)
Your two systems will be
8A + 3S = 79$
your 2nd will be
10A + 5S = 105$
The lesser x is 2 and the greater x is 3. The x values can be determined by setting each set of numbers in parenthesis equal to 0, so 3x-6=0 and -x+3=0. To solve, take the first set, 3x-6=0 and divide by the greatest common factor, 3, leaving you with x-2=0. Add 2 to each side so that x=2. On the other side, take -x+3=0 and subtract three from each side. Take your new equation -x=-3 and multiply by -1 so that x=3. Therefore x=3 and x=2.
