ASAP HELP!! CAN SOMEONE PLS HELP ME WITH 20? U HAVE TO USE 18 and 19 to help you!!! THANK U SM!

18) Let x be the number of coins in the pouch:

3x + 3 = 9; subtract 3 from each side:

3x + - 3 = 9 -3

3x = 6 . Now divide both side by 3:

x = 2 (in each pouch we have 2 coins)

19) SAME logic:

4x + 1 = 2x + 7; subtract 1 from each side:

4x + 1 - 1 = 2x + 7 - 1
4x = 2x + 6; now subtract 2x from each side:

4x - 2x = 2x + 6 - 2x

2x = 6   and x = 3 (each pouch contains 3 coins)

HELP PLEASE!<br><br> Three consecutive integers have a sum of 57. Find the integers.
Maurinko [17]

Answer:

18, 19, and 20.

Step-by-step explanation:

Consecutive means beside. Numbers 2 and 3 are consecutive integers. Given this question, numbers 6, 8, and 9 could possibly be the answer. However, we don't know this, so let's represent the 6 as x, 7 as x+1. 9 is x+2. We know when these are added together the sum is 57, so 3x+3 should be 57. Now, solve as a normal algebraic question.

Marie has a small copy of rene magritte famous painting, The Schoolmaster. Her copy has dimensions 2 inches by 1.5.The scale of
klemol [59]
Ok so 1inch=40cm

2 inches by 1.5
multiply everybody by 40 and make them all centimeters
20*2=80
1.5*40=60

80cm by 60cm


1inch=2.54cm
find how many inches in 1 cm
divide both sides by 2.54
1/2.54inch=1cm

80 by 60 cm
multiply that by 1/2.54 nd find inches iquivlent

80 times 1/2.54=31.4960629921259842519685037008
60 times 1/2.54=23.622047...


ok so

dimentions is 31.4960629921259842519685037008 inches by 23.622047 inches

Determine the number of x-intercepts that appear on a graph of each function.f (x) = (x - 6)2(x + 2)2
Orlov [11]
Short answer There are 2 places where the graph touches the x axis just as you said.
I take this to mean f(x) = (x - 6)^2*(x + 2)^2

 
There are two places where the graph touches the x axis but that is not an intercept. 
When a graph just touches the x axis, that counts as a root. As the graph shows, these 2 places are
x = 6 and
x = - 2 is where they touch.

If you have a graphing calculator, you can see what this looks like for yourself. The window settings are 
x min = - 3
x max = 7
y min = 0
y max = 250. 

There is a local maximum between x = -2 and x = 6.
So the answer, once again is at x = -2 and x = 6 and that makes 2 roots for the equation.
