Answer:
B
Step-by-step explanation:
A translation of 3 units up, means adding 3 to the y- coordinate of the original points while the x- coordinates remain unchanged, that is
S(1, 1) → S'(1, 1 + 3) → S'(1, 4)
T(2, - 3) → T'(2, - 3 + 3) → T'(2, 0)
U(4, 0) → U'(4, 0 + 3) → U'(4, 3)
The answer is 1/2 when you simplify it
Answer:18
Step-by-step explanation:
Sin72=cosy
0.9511=cosy
Y=cos(inverse)0.9511
Y=18
Answer:
in this method a variable is expressed in terms of another variable from one equation and it is substituted in remaining equation.
Step-by-step explanation:
solve:x+2y=9 and 3x-y=13.
x+ 2y=9…be the first equation
3x-y=13…be the second equation
from first equation
x=9-2y…be the third equation substituting value of x from third equation in second equation, we get
3(9-2y)-y=13
or, 27-6y-y=13
or, y=2
now,
substituting value of y in third equation, we get,
x=9-2×2
=9-4
=5
the required value of x and y are 5&2
