The degree of a line is 180, so..
Put it into an equation form: 5x + 75 = 180
1st combine like terms by subtracting 75 from 180
now your equation looks like this: 5x = 105
next you divide 5 from both sides, 105 divided by 5 is 21, so your answer is: x=21
I hope this helps!♥
Answer:
Step-by-step explanation:
We know that the dotted graph is the upsidedown of the black graph, f(x) so the dotted graph must be the negative of f(x)
Let's say y is the dotted graph
And it seems that the dotted graph is 4 units to the left of the black graph. so

Therefore option (a) is the correct answer.
Answer:
y = -2
Step-by-step explanation:
The y-intercept is the y-coordinate of the point where the curve intersects (crosses) the y-axis, i.e. when x = 0.
Therefore, to find the y-intercept, substitute x = 0 into the function:
Therefore, the curve crosses the y-axis at (0, -2) and so the y-intercept is
y = -2.
