PLEASE HELP!!!
Answer:
Ok:
Step-by-step explanation:
So f°g . means f(g(x)). (The ° should be more center and bigger but I don't know to do that on a keyboard). f(g(x)) means that you replace the x in f(x) with the g(x) function. i.e:
if f(x) = 2x+2
and g(x) = [tex]x^2[/tex]
f(g(x)) = [tex]2x^2+2[/tex].
Similarly, in this case, we get f(x) = 2x-3 and g(x) = 3x-2.
Then, f(g(x)) or f°g(x) is 2(3x-2) - 3.
And we plug in -2 to solve:
2(3(-2)-2)-3.
and get -19.

what is the value of 2 power 1
Answer:
2
Step-by-step explanation:
[tex]2^1=2[/tex]
Any number to the power of 1 equals the number itself
Answer:
2
Step-by-step explanation:
2 ^1 is the same as saying multiplying 2 one time. 1x2 =2. Another example would be 2^2. You would multiply 2 by 2 twice, so two 2s.
Isabel purchased a prepaid phone card for $20. Long-distance calls cost 18 cents a minute using this card. Isabel used her card only once to make a long-distance call. If the remaining credit on her card is $14.24, how many minutes did her call last?
Answer:
20 - .07c = 17.13
20 - 17.13 = 2.87
2.87/7 = 41

Answer:
mDE = 9
Step-by-step explanation:
mCD and mDE must add up to mCE
Step 1: Set up equation
mCD + mDE = mCE
5x + 1 + 3x + 3 = 20
Step 2: Solve for x
Combine like terms: 8x + 4 = 20Subtract 4 on both sides: 8x = 16Divide both sides by 8: x = 2Step 3: Find mDE
mDE = 3x + 3
mDE = 3(2) + 3
mDE = 6 + 3
mDE = 9

What is equivalent to (r^-7)^6
In a certain city, three newspapers A, B, and C are published. Suppose that 60% of the families in the city subscribe to newspaper A, 40% of the families subscribe to newspaper B, and 30% subscribe to newspaper C. Suppose also that 20% of the families subscribe to both A and B, 10% subscribe to both A and C, 20% subscribe to both B and C, and 5% subscribe to all three newspapers. (i) What percentage of the families in the city subscribe to at least one of the three newspapers? (ii)What percentage of the families in the city subscribe to exactly one newspaper?
Answer:
(i) = 85%
(ii) = 30%
Step-by-step explanation:
The question is a probability question.
We will need the following values:
P(A) = 60%
P(B) = 40%
P(C) = 30%
P(AnB) = 20%
p(AnC) = 10%
P(BnC) = 20%
P(AnBnC) = 5%
(i) To determine the percentage of the families in the city that subscribe to at least one of the three newspapers:
P(A) + P(B) + P(C) + P(AnBnC) - P(AnB) - p(AnC) - P(BnC)
= 60% + 40% + 30% + 5% - 20% - 10% - 20%
= 85%
(ii) To determine the percentage of the families in the city that subscribe to exactly one newspaper:
P(at least one paper) - p(AnB) - p(AnC) - P(BnC) - P(AnBnC)
= 85% - 20% - 10% - 20% - 5%
= 30%

4x-5y+16 =0
2x+y-6 =0
bicol method)
Answer:
Step-by-step explanation:
Given the simultaneous equation
4x-5y+16 =0 ....... 1
2x+y-6 =0 ...... 2
Let us solve to get the variable x and y:
The equation becomes
4x-5y =-16 ........ * 1
2x+y =6 ...... *2
Using Elimination method
Multiply eqn 1 by 1 and eqn 2 by 2
4x-5y =-16
4x+2y =12
Subtract resulting equation
-5y-2y = -16-12
-7y = -28
solve for y
-7y/-7 = -28/-7
y = 4
Substitute y = 4 into equation 2 to get x
2x+y =6
2x + 4 = 6
2x = 6-4
2x = 2
x = 2/2
x = 1
hence x is 1, y is 4

Step-by-step explanation:
Beth and Pam both did some babysitting in the summer. Pam earned $4 less than 3 times as much as Beth. Together they earned $860. How much money did each person earn babysitting?
======================================================
Work Shown:
B = amount Beth earned
P = amount Pam earned
amounts are in dollars
Pam earned $4 less than 3 times as much as Beth, so,
P = 3B-4
Together they earned $860, meaning
P+B = 860
Plug the first equation into the second. Solve for B
P+B = 860
3B-4+B = 860
4B-4 = 860
4B = 860+4
4B = 864
B = 864/4
B = 216
Use this to find P
P = 3B-4
P = 3*216-4
P = 648-4
P = 644
Beth earned $216 and Pam earned $644.
----------------------------------------
Check:
B+P = 860
216+644 = 860
860 = 860
First equation is true
P = 3B-4
644 = 3*216-4
644 = 644
Second equation is true
Both equations are true when (B,P) = (216,644) so the solutions have been confirmed.
