I think it's c) 5 because the first pentagon is 5 and then decreases to a 1. i divided it and i got 5. it decreased by 5.
Answer:C) x2 + y2 =45
Step-by-step explanation:
The equation of a circle in standard form is (x-h)2+(y-k)2=r2.
Since you know the center is (0,0), you can sub this is value in for h and k, then use the point (3,6) to sub in for x and y and you will find r2 =45. Hope that helps :)
Answer:
We can write this equation in slope-intercept form
y
=
m
x
+
b
where
m
is the slope and
b
is the
y
-intercept.
We know
m
=
−
4
and
b
=
6
, so we can insert these into the equation to get
y
=
−
4
x
+
6
Hope this helps!
I think its 8, not too sure tho
Answer:
Step-by-step explanation:
Thanks to girls from relatives and earnings from an afterschool job, she has already saved $3700. If she's a seed in her goal of saving $150 per month, then if she saves for x months, the total amount that she would be have earned is
150x + 3700
1 year = 24 months
If she saves for 2 years, it means that the number of months for which she saved is 2 × 12 = 24 months. Therefore, the total amount
that she will have two years from now is
150 × 24 + 3700
= 3600 + 3700
= $7300
