Answer:
y = sin(x + 90°)
Step-by-step explanation:
cos 0 = 1
Since the point (0, 1) is on the graph, this graph is y = cos x, but that is not a choice, so this must be the graph of the sine function with a horizontal translation.
sin 0 = 0
sin 90° = 1
The translation is 90°.
Answer: y = sin(x + 90°)
Answer:
Step-by-step explanation:
x²-8x+ 14 =2x+7
x² - 8x +14 - 2x - 7 = 0
x² - 10x + 7 = 0
Answer:
x = 13/8
y = -45/8
Step-by-step explanation:
9x + y = 9
3x + 3y = -12
Divide the second equation by 3
x+y = -4
Multiply this by -1
-x -y = 4
Add this to the first equation to eliminate y
9x + y = 9
-x -y = 4
-----------------
8x +0 = 13
Divide by 8
8x/8 = 13/8
x = 13/8
Now find y
x+y = -4
13/8 +y = -4
Subtract 13/8 from each side
13/8 -13/8 +y = -4-13/8
y = -32/8 - 13/8
y = -45/8
