Answer:
answer is 90 for first term
Step-by-step explanation:
Let the terms be
First term x
We will use the formula s∞=x/1−r to find the sum of an infinite geometric series, where −1<r<1.
We know the sum and the common ratio, so we'll be solving for x where r =4/5
s∞=x/1−r
450=x/1−4/5
450=x/1/5
450=5x
x=90
this is the first term x1 = 90
we know that common ratio is 4/5, so multiplying the first term by factor 4/5 to get the second term
90 x 4/5= 72 second term

The slope is -3 and the y-intercept is -1
Answer:
A -19
B -35
C -180
D-9
Step-by-step explanation:
The reflection of the point (x,y) across the x-axis is the point (x,-y), so take the coordinates of each point and change them accordingly then graph them.
