Answer:
CPCTC
Step-by-step explanation:
If abc=def is given,
then using the cpctc rule. (corresponding parts of congruent triangles are congruent) should state this answer.
Put the first equation in slope-intercept form, or y = mx + b. Start by subtracting y from both sides.
2x - y = -10, subtract 2x from both sides.
-y = -10 - 2x
Divide both sides by negative one.
y = 10 + 2x
To find the slope when the equations are in slope-intercept form you look at the coefficient of x. The first equation has the slope of 2 (which we just found), and the second equation has the slope of -2.
Parallel lines have the same slope and perpendicular lines have opposite reciprocal slopes. Since 2 and -2 are neither of these, your answer is neither.
Answer:
Step-by-step explanation:
(fx+cd)/(x-f)=1/2
Cross multiplication,
2*(fx + cd) = 1 * (x-f)
2fx + 2cd = x - f
2fx - x = -2cd - f
x (2f - 1) = -2cd -f
x = (-2cd-f )/ (2f-1)
