Step-by-step explanation:
So you solve the equation for x and then solve it for y. If the x and y match the given ordered pair then the answer is yes
Here,
cos(x) = sin(35)
cos(x) = cos(90-55)
cos(x) = cos(55)
x = 55
Answer: one solution x + 3 = 5 x = 2 no other other value for x is possible
No solution: (x + 3) = 2(x +3)
Infinitely many solutions: x+3 = 3 + x
Step-by-step explanation:
why (x + 3) = 2(x +3) has no solution. Can you solve?
x+3=2x+6 -x=3 x=-3 substute -3 for x
(-3)+ 3)= 2[(-3) +3]
-3+3 = -6 +3
0 = -3 False!
x+3 = 3 + x has infinitely many solutions. Substitute any number for x, and the equation is true (5)+3=3+(5) 8=8 . 11111+3 =3+11111 11114=11114
The altitude of a triangle is a line segment through a vertex and perpendicular to a line containing the side opposite the vertex.
