Answer:
x=-1/3, y=-13/3. (-1/3, -13/3).
Step-by-step explanation:
y=x-4
4x-y=3
------------
4x-(x-4)=3
4x-x+4=3
3x+4=3
3x=3-4
3x=-1
x=-1/3
y=-1/3-4
y=-1/3-12/3=-13/3
Answer:
1 Simplify 3/12 to 1/4
1/4 =1/4
2 Since both sides equal, there are infinitely many solutions.

18%
Step-by-step explanation:
total = 72 + 328 = 400
percent non-fiction = 72/400 × 100% = 18%
Answer:
Step-by-step explanation:
step 1
Find the scale factor
we know that
If two figures are similar, then the ratio of its corresponding sides is equal to the scale factor
Let
z----> the scale factor
x----> corresponding side of the larger trapezoid
y----> corresponding side of the smaller trapezoid
we have
substitute
step 2
Find the area of the larger trapezoid
we know that
If two figures are similar, then the ratio of its areas is equal to the scale factor squared
Let
z----> the scale factor
x----> area of the larger trapezoid
y----> area of the smaller trapezoid
we have
substitute
Answer:
When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x). the line y = -x is the point (-y, -x).
