Answer:
f(x) = |[tex]\frac{1}{9}[/tex](x+1)|-3
Step-by-step explanation:
The value representing the horizontal scaling must be placed inside the absolute value, and we need to put () around x - 1 to change the horizontal shift as well. And remember that we must use the reciprocal in the function, so instead of writing y = |9(x+1)|-3, we need to write y = |[tex]\frac{1}{9}[/tex](x+1)|-3.
Three people take 2½ hours to deliver leaflets to 270 houses. Assuming all people deliver leaflets at the same rate, how long will it take five people to deliver leaflets to 405 houses? Give your answer in hours and minutes.
Answer:
3 hours 45 minutes
Step-by-step explanation:
270/2 1/2 = 108. This means they are delivering 108 leaflets an hour. Then you divide 405 by 108 and get 3.75, which is 3 hours and 3 quarters of an hour. since a quarter of an hour is 15 minutes it would be 3 hours 45 minutes.
Harrison has 12 coins in quarters and nickels. He determines that they have a total value of $2.00.
a) Write a system of equations that could be used to find the number of each coin he has.
Answer:
See belowStep-by-step explanation:
Let the number of nickels is n, number of quarters is q.
We know that:
Nickel = 5¢, quarter = 25¢, $2 = 200¢As per given we can set the following system:
n + q = 125n + 25q = 200Solving this we get:
n = 5, q = 7What are all the factors of 54?

Chose the graph which represents the solution to the inequality
Answer:
See answers below.
Step-by-step explanation:
x = - 4x + 15 Change the ≤ to an = and solve for x
4x = 4x
5x = 15
x = 3 Now replace the equal sign with ≤
x ≤ 3

Answer:
Roman
Step-by-step explanation:
An easy way to solve this is looking at whether the line has a positive or negative slope. We read graphs from left to right so if the line is increasing from left to right, it has a positive slope while a line decreasing from left to right has a negative slope. Since the line shown is decreasing from left to right, it will have a negative slope and Roman is the only one out of the two that shows a negative slope. To check to see if he's correct, we can check the y-intercept. The y-intercept of the line is 8 and Roman also has 8 written in the expression. Hence, meaning Roman is correct.
Best of Luck!

Step-by-step explanation:
x² = -64
= -1 · 64
Using -1 = i²:
x² = 64 · i²
Using 64 = 8²:
x² = 8² · i²
= (8·i)²
Taking the square root of both sides:
x = 8i
Which graph is right?
Answer:
top one
Step-by-step explanation:
You are not including -2 (else it would be a greater or equal sign) so the dot has to be empty. You can rule out the middle options.
At this point you either remember that "greater than" means "to the right of" or you pick a convenient number, ie, 0. see that your inequality is true (zero is greater than -2) and you pick the graph where the solid line includes 0.

Which value of m is a counterexample for the following statement?
If m is an odd prime number, then m + 2 is also prime.
7

5
9
11
Answer: 7
The prime numbers here are 3, 5, 7, and 11. This means that 9 is not prime. Since 7 +2 is 9, this disproves that m + 2 is also prime.

Give your answer in its simplest form.
PLEASE HELP BRAINLIST TO FASTEST AND CORRECT ANSWER
Answer:
Well lucy has a 50/50 chance to get a odd card so that is it
Step-by-step explanation:
The ratio of even cards to odd cards that Lucy has is 3:4 in its simplest form.
Let's denote the number of even cards as "x" and the number of odd cards as "y".
The probability of choosing an even card is given as [tex]\frac{3}{7}.[/tex]
The probability of choosing an even card is calculated by dividing the number of even cards by the total number of cards:
Probability of choosing an even card = Number of even cards / Total number of cards
Therefore, we have:
[tex]\frac{3}{7} = \frac{x}{x+y}[/tex]
To find the ratio of even cards to odd cards, we can set up the equation:
[tex]\frac{x}{y} = \frac{3}{4}[/tex]
Therefore, the ratio of even cards to odd cards that Lucy has is 3:4 in its simplest form.
