First things first both of these equations are linear equations so we are going to be using y=mx+b format. M represents the slope and b represents the y intercept. So y=6x-4 will now be m=6, b=-4 and y=5x-3 will be m=5, b=-3. Now we will graph the lines so y=6x-4 the y intercept is (0,-4). x-1 means y=6 times 1-4=6-4=2 (1,2). The y intercept for y=5x-3 is (0,-3). x=1 y=5 times 1-3=5-3=2. (1,2). Then we would graph.

d

step-by-step explanation:

d

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough
