EMERGENCY!!!! Each hour, every person who knows a rumor tells two other people. If one person starts the rumor, then after the first hour, three people know the rumor. The next hour, those three people each tell two more people. After eight hours, how many people will know the rumor? You do not have to include units in your answer. (I've asked this question before but the answers I got were 384 and 64 and they were both wrong)
Answer:
After eight hours 6,561 people will know the rumor.
Step-by-step explanation:
Since each hour, every person who knows a rumor tells two other people, so that if one person starts the rumor, then after the first hour, three people know the rumor, and the next hour, those three people each tell two more people, to determine after eight hours, how many people will know the rumor, the following calculation must be performed:
Hour 0 = 1
Hour 1 = 1 + 2 = 3
Hour 2 = 3 + 2 x 3 = 9
Hour 3 = 9 + 2 x 9 = 27
Hour 4 = 27 + 2 x 27 = 81
Hour 5 = 81 + 2 x 81 = 243
Hour 6 = 243 + 2 x 243 = 729
Hour 7 = 729 + 2 x 729 = 2,187
Hour 8 = 2,187 + 2 x 2,187 = 6,561
Therefore, after eight hours 6,561 people will know the rumor.

Graph the function y = 6 – 2x. Click the intercepts to show the coordinates.
Answer:
Step-by-step explanation:
Let's find and use the intercepts. They speed up graphing of lines.
y-intercept: In y = 6 – 2x, let x = 0. Then y = 6, and the y-intercept is (0, 6).
x-intercept: In y = 6 – 2x, let y = 0. Then 2x = 6, and x = 3. The x-intercept is therefore (3, 0).
Plot these two points and then draw a line through both.

Omar divided a circular pizza into 8 equal sections. He gave his friend
3 sections. Explain why the amount he gave to his friend can be represented
by a point plotted to the right of 0 on a number line. Then write the
amount he gave to his friend as a decimal.
Answer:
the amount he gave his friend is a positive fraction, therefore to the right of 0 on the number line. the decimal is 3/8 which = 0.375

Answer:
Given function
h(x) = 2x - 1#15 Find the inverse of h(x)
Substitute x with y and h(x) with x and solve for y:
x = 2y - 12y = x + 1y = 1/2x + 1/2The inverse is:
h⁻¹(x) = 1/2x + 1/2#16 The graph with both lines is attached.
The x- and y-intercepts of both functions have reversed values.
#17 Table of the inverse function will contain same numbers with swapped domain and range.
Initial look is like this:
x | -3 | -2 | -1 | 0 | 1 | 2 | 3h⁻¹(x) | -1 | | 0 | | 1 | | 2The rest of the table is filled in by finding the values:
x | -3 | -2 | -1 | 0 | 1 | 2 | 3h⁻¹(x) | -1 | -0.5 | 0 | 0.5 | 1 | 1.5 | 2Are both of theses sets of orderd pairs a function? {(4,2) (3,15) (2,18) (1,21)} {(-6,8) (-3,4) (3,0) (6,-4)

A fine fabric was selling for $10.50 per half yard. Joni bought 2 1/3 yards. How much did he spend? Brainliest for correct answer.
Answer:
45.5
Step-by-step explanation:
First you would find 1/3 third of 10.50 and it is 3.5, you would then do 10.50 x 4 since it said 10.50 per half a yard, so you would do times 4 and you would get 42, you would then add 42 + 3.5 which equals 45.5.
Answer:
$24.50
Step-by-step explanation:
10.50 * 2 1/3 = 24.50

Find the 88 term of the arithmetic sequence 4,-1,-6
Answer:
an = a1 + d(n - 1)
a88 = 4 + (-5)(88 - 1)
a88 = 4 + (-5)(87)
a88 = 4 - 435
a88 = -431
So, the 88th term of the arithmetic sequence is -431.
5x + 7y = 25
5x - 2y = -65
solve using elimination
(step by step please)
5x+7y=25
5x-2y=-65
subtract both of the equations
5x-5x=0
7y--2y= 7y+2y=9y
25--65=25+65=90
0+9y=90
9y=90
divide both sides by 9 to get y by itself
9y/9=90/9
cross out 9 and 9 which becomes 1*1*y=y
90/9=10
y=10
find x by using the substitution method
5x+7y=25
5x+7(10)=25
5x+70=25
move +70 to the other side
sign changes from +70 to -70
5x+70-70=25-70
5x=-45
divide both sides by 5 to get x by itself
5x/5=-45/5
cross out 5 and 5 then becomes 1*1*x=x
-45/5=-9
x=-9
answer:
(-9,10)
