It d over 3 u 2 text me if you need more help hope this helps u a little bit more.
N-10+9n-3
n+9n=10n
10-3=7
so the answer is....
-13+10n
A, C, and E.
you can check them by putting into y=mx+b form. if m is negative then as domain increases range decreases.
Answer:
b=9,a=12
Step-by-step explanation:
I solved by substitution:
b = 3/4a ---> plug this into the other equation
a + b = 21 is now a + 3/4a = 21
Reduce: 7/4a = 21
a = 12
Now solve for b:
b=3/4a is now b=3/4(12)
b=9
Answer:
BC≈8,38
Step-by-step explanation:
AB=a
BC=c
CA=b
a²+b²=c²
3.3²+7.7²=c²
√70,18=√c²
c≈8,38
