Question 3(multiple choice worth 5 points) (3.07a lc) a set of equations is given below: equation e: c = 2d + 1 equation f: c = 3d + 7 which statement describes a step that can be used to find the solution to the set of equations? equation f can be written as c = 3(c − 1) + 7. equation f can be written as c = 2(c − 7) + 1. equation f can be written as d + 1 = 3d + 7. equation f can be written as 2d + 1 = 3d + 7.

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

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
