The answer is 1because a number is multiple by 20 then 200 and multiple by 3 -7=1
Answer:
55 guests
Step-by-step explanation:
131 = 21 + (2x)
subtract 21 from both sides
110 = 2x
x = 55 guests
U can find the common ratio by dividing the 2nd term by the first term
r = -9/3 = -3
an = a1 * r^(n - 1)
a1 = 1st term = 3
r = common difference = -3
now sub
an = 3 * -3^(n - 1) <== ur formula
domain : all integers where n > = 1 <==
Slope intercept form: y = mx+ b
m = slope
b = y-intercept
Since we don't have "b", thats what we need to solve for.
-4 = -3/4(8) + b
-4 = 6 + b
-10 = b
Put everything we know back into the original form.
y = -3/4x - 10
Best of Luck!
