Answer:
a. A = -1 and B = 1
b. A = 7 and B = -5
Step-by-step explanation:
a.
To the equation be true, the "x-parts" and "nonx-parts" mist be the same, so:
Ax + Bx = 0
(A + B)x = 0
A + B = 0
A = -B
B - A = 2
B - (-B) = 2
2B = 2
B = 1 and A = -1
b.
To the equation be true, the "x-parts" and "nonx-parts" mist be the same, so:
Ax + Bx = 2x
(A + B)x = 2x
A + B = 2
A = 2 - B
2A + 3B = -1
2*(2-B) + 3B = -1
4 - 2B + 3B = -1
B = -5 and A = 2 - (-5) = 7
Answer:
75
Step-by-step explanation:
x= 75
been that the line is perpendicular (the two lines that intersect in such a way that they have a right angle, or a 90 degree angle, between them)
It's 13=13. Add the numbers in the parenthesis first! So it would be 9+4=8+5, then just add them up and you get 13 on each side!
