Answer:

(-8 , 0)

(10 , 0)

Step-by-step explanation:

then (-8 , 0) and (10 , 0) are x-intercepts Of the polynomial f

the others are not because (for instance):

Can some help me with this question

To find the equation of this line in slope-intercept form (y = mx + b, where m is its slope and b is its y-intercept), we naturally need the slope and the y-intercept. We can see that the line intersects the y-axis at the point (0, 4) so our y-intercept is 4, and the line rises 4 along the y-axis for every 2 it runs along the x-axis, so its slope is 4/2 = 2. With this in mind, we can write the line's equation as

y = 2x + 4

Angle CMW and angle WML together form angle CML. Angle CMW is a right angle. What must be true about angle CML?
ANTONII [103]
CML must be an obtuse angle.

Since CMW and WML together form CML, and CMW is a right angle, then CML must be larger than a right angle, which makes it obtuse.
