ok Step-by-step explanation:
The first thing I should do with these two points is find the slope of the line.
m = (y2 - y1)/(x2 - x1)
m = (-1 - 7)/(-9 - -9)
m = -8/0
The slope is undefined. We cannot divide by 0. This makes sense because the points (-9, 7) and (-9, -1) would be right on top of each other. This is a vertical line that has an x-intercept at -9.
Your equation would be x = -9.
Answer:
?
Step-by-step explanation:
The answer is 4700 megabytes.
1 giga = 1000 mega
1 gigabyte = 1000 megabyte
4.7 gigabyte = x megabyte
1 gb : 1000 mb = 4.7 gb : x
x = 1000 mb * 4.7 gb : 1 gb
x = 4700 mb
Geometric progresión:
we can calculate any term, using this rule:
an=a₁*r^(n-1)
a₁=the first term
r=the common ratio
a₆=128
r=2
an=a₁ * r^(n-1)
128=a₁ * 2⁶⁻¹
128=a₁ * 2⁵
128=a₁ * 32
a₁=128/32=4
Solution: a₁=4
