Answer:
126
Step-by-step explanation:
i don't know if it's correct or not
The translation is not changing the angles, because the all the points were moved 3 units to the right and two units down, so all the lines preserved their slopes.
Then if the angles A and B were 110 and 70 the images preserve the same angles.
Answer: The period of the given function is 10
Step-by-step explanation:
The period of a function is the distance required to complete a full cycle (In which the portion of the graph repeats itself however in both direction)
Since, by the given diagram,
After 10 unit, the one cycle of the function is completed,
⇒ The period of the given function is 10.
Answer:
y = -7/9 x +1
Step-by-step explanation:
7x + 9y = 9
The slope intercept form is y = mx+b where m is the slope and b is the y intercept
Subtract 7x from each side
7x -7x+ 9y =-7x+ 9
9y = -7x+9
Divide each side by 9
9y/9 = -7/9 x +9/9
y = -7/9 x +1
The slope is -7/9 and the y intercept is 1
