Answer:
-7√5
Step-by-step explanation:
I'll transcribe your verbal question into a symbolic one as best I can:
-2√20 - √125
Note how √20 = √4*√5 and √125 = √25 *√5. Thus,
your -2√20 - √125, after we've factored √5 out of both terms, becomes
-2(2)√5 - 5√5, or -2√5 - 5√5, which combines to form
-7√5 (answer)
Answer:
-25
Step-by-step explanation:
This equation is in the form y = mx + b where m is the slope and b is the y-intercept. Knowing this, we see that -25 is in place of m, so that's our answer.
Rewrite in standard form using (h,k) to find the vertex.
(3,4) is the answer.
