Hi there!
Let's first determine the x-intercept. When dealing with an x-intercept we must realise the y-coordinates equal 0.
Add 21 to both sides.
Divide both sides by -2.
Therefore, the x-intercept is the point (10 1/2; 0).

Now let's continue with the y-intercept, which is easier. When dealing with an y-intercept we must realise the x-coordinates equal 0.
Therefore, the y-intercept is the point (0; -21).

Answer:
Step-by-step explanation:
Recall the mnemonics SOH-CAH-TOA
The sine ratio is the length of the opposite side expressed over the hypotenuse.
Take the sine inverse of both sides to get;
The cosine ratio is the length of the adjacent side expressed over the hypotenuse.
Take the cosine inverse of both sides to get;
Step-by-step explanation: Answer is 1.5
There are 2 similar triangles in the figure Triangle CBD and Triangle CAE. We are going to use a similarity proportion between there congruent sides.
Now let plug in
Cross multiply and x=
or 104/9. Now we are going to find Ba. Since CB+BA=CA via the segment addition rule. 4+x=104/19. x=104/19-76/19 which equals 28/19. 28/19 is about 1.5.
