Answer:
Geometric
Ratio = 5:1
Step-by-step explanation:
Geometric sequence is when the relation between the numbers in the sequence is multiplication or division.
For an arithmetic sequence, it is difference as it includes addition or subtraction, but since this sequence is division, we have to use ratios.
The ratio is 5:1 because the previous number is 5 times larger than the following one.

equation of line passing through (1,-7)( -4,8)
First let's find slope (m)
m = (8+7)/(-4-1)
= 15/-5 = -3
(x1,y1) = (1,-7)
Plugging above value in
y - y1 = m( x-x1)
y+7 = -3( x-1)
y+7 = -3x +3
y+3x +4=0
Answer:

When you say "I want to make sure that I solved them correctly,
the tasteful, less suspicious thing to do is to list YOUR solutions,
so that the responder can either say "that one's correct" or else
show you how to do it.

a). The probability of each one is 1/8 = 12.5% .
b). There's only one of those on the list. 12.5%
c). 12.5%
d). There are 3 ways that can happen. 3/8 = 0.375 = 37.5%
2). There are 16 possible outcomes.
a). Prob of each outcome is 1/16 = 0.0625 = 6.25% .
b). There's only 1 way that can happen, so it's 6.25% .
c). There's only 1 way that can happen, so it's 6.25% .
d). There are 6 ways that can happen. Prob = 6/16 = 37.5%
e). There are 4 ways that can happen. Prob = 4/16 = 25%
Answer:
-18
Step-by-step explanation:
f(x) = x² - 3x -10
f(-10) = (-10)² – 3(-10) – 10
f(-10) = 100 + 30 - 10
f(-10) = 120
f(-5) = (-5)² – 3(-5) – 10
f(-5) = 25 + 15 - 10
f(-5) = 30
=====
The <em>average rate of change</em> is the slope m of the straight line joining the two points.
m = (y₂ - y₁)/(x₂ - x₁)
m = (30 - 120)/(-5 – (-10))
m = -90/(-5+10)
m = -90/5
m = -18
