Answer:
f(x) = 
Step-by-step explanation:
∵ The zeroes of the function are x = -4 and x = -1
∵ x + 4 = 0 and x + 1 = 0
∴ The factors of the function are (x + 4) (x + 1)
∴ The function = (x + 4) (x + 1)
∴ f(x) =
Answer:
B) 135 degrees
A) 83 degrees
Step-by-step explanation:
Each interior angle of a regular octagon is 135 degrees large.
In question two, <1 is an inscribed angle. A circle has 360 degrees, so the intercepted arc of <1 is 166, so m<1=83.
Hope it helps <3

Answer:
- The y-intercept is (0, -37/7).
Explanation:
When you have one point and the slope of a line you can find its equation by using the point-slope form of the linear function:
- m = slope
- point = (a, b)
- point-slope equation: (y - b) = m (x - a).
Now substitute m = -1/7 and (a,b) = (5, - 6)
Solve for y:
- y = -(1/7)x - 37/7 ← this is the slope-intercept form of the equation.
The y-intercept is the point when x = 0. So, the corresponding y-coordinate is the constant term in the last equation:
And the y-intercept is the point (0, -37/7).
