Answer:
9 down, 5 right, compression by factor of 2, reflection across the x- axis
Step-by-step explanation:
Answer:
(3, 5)
Step-by-step explanation:
y = 2x - 1
3x + 2y = 19
In the second equation, substitute 2x - 1 in for y, since y equals 2x - 1 in the first equation. Solve for x.
3x + 2(2x - 1) = 19
3x + 4x - 2 = 19
7x - 2 = 19
7x - 2 + 2 = 19 + 2
7x = 21
7x/7 = 21/7
x = 3
Pick the first equation to solve for y since it says y =. Substitute 3 in for x.
y = 2x - 1
y = 2(3) - 1
y = 6 - 1
y = 5
In trigonometry laws, there's a equation to solve this problem :
sin (a-b) = sin(a) . cos(b) - sin (b) . cos(a),
so by assuming that a = π, b = θ, so the equation will be like this..
sin (π-θ) = sin(π) . cos(θ) - sin (θ) . cos(π),
= 0 . cos(θ) - sin(θ) . (-1)
= sin(θ) = 0.57
Hope this will help you :)
254 is your answer because you don't want to put the 5 at the end because the you round to 260
