Answer:
-17
Step-by-step explanation:
plug in x and y
10(-1)-3+2(-1)(2)
10(-1)= -10
2(-1)(2)= -4
-10-3-4
10+3+4= 17
don't forget the negative -17
The answer here is D, <span><span>Percent = 90%, Amount = unknown, Base = 70</span>
We can solve this by using what we know. The first step is to note that 90 is the percent (since it has the percent sign). In addition, we know that 70 is the base (since we're taking a percent of 70). That gives us our answer of </span> D, <span>Percent = 90%, Amount = unknown, Base = 70.</span>
If you’re asking how many ears, paws, and tails there will be in total, well just multiply 2 by 3, 4 by 3, and 1 by 3!
2 x 3 = 6
4 x 3 = 12
1 x 3 = 3
Is that it?
Geometric is
an=(a1)(r^(n-1))
a1=first term
r=common ratio
so
a1=-5, given
a2=20 so
a2=20=-5(r^(2-1))
20=-5(r^1)
20=-5(r)
divide both sides by -5
-4=r
the formula is
an=-5(-4)^(n-1)
