Answer:
True: A dilation with a scale factor of 1/3 is a reduction.
False: A dilation with a scale factor of 2 is a reduction.
Step-by-step explanation:
A dilation with a scale factor between 0 and 1 is a reduction because the image will decrease in size.
On the other hand, a dilation with a scale factor greater than 1 is an enlargement, where the image increases in size.
So, the statement that a dilation with a 1/3 scale factor is a reduction is true.
The other statement is false, which says a dilation with a scale factor of 2 is a reduction.

Danielle walked from her house to several locations in her town. The graph represents her distance from home after x hours
What is the domain when the function is increasing?
What is the domain when the function is decreasing?
What is the domain when the function is constant?
Answer:
The answer for A. Would be 1 mile B. 2mph C. 4mph and the rest Im still working on
Step-by-step explanation:
a. How far from home was Danielle after 1/2 hour?
According to the graph, after half hour, Danielle was 1 mile far from home.
b. What was Danielle's speed between 0 and 1 hour?
To find the speed we have to apply the formula:
From and , Danielle went from to . Replacing this values, we calculate the speed:
Therefore, the speed between 0 and 1 hour is 2 miles per hour.
c. What was Danielle's speed between 1 and 2 hours?
The Danielle's speed between 1 and 2 hours is zero (). Because, according to the graph, during this time, Danielle didn't move, and without move, there's no speed.
d. What is the domain when the function is increasing?
The domain when the function is increasing refers to the increasing x intervals.
From the graph, this increasing interval is from 0 to 1 hours only, it's the only period of time when Danielle was increasing her position.
e. What is the domain when the function is decreasing?
The parts of the decreasing domain are:
From 2 to 3 hours.
From 3 and a half to 4 hours.
In the graph, you can see these decreasing intervals, which are characterized by a downwards direction of the line.
f. What is the domain when the function is constant?
The parts where the function is constant:
From 1 to 2 hours.
From 3 to 3 and a half hours.
Constant intervals, means no increase, no decrease, just an horizontal line.

How do you convert 18x − 17y = 18 into slope intercept form?
Answer:
[tex]y=-\frac{18}{17} + \frac{18}{17} x[/tex]
Step-by-step explanation:
First move x terms and numbers on one side, keep y on the other side.
y = mx+b is the form
18x -17y = 18
subtract 18x from both sides
-17y = 18 - 18x
divide both sides by -17
y = -18/17 + 18/17x

Please help- A bakery sells cakes for $18 each and pies for $15 each. Last weekend the bakery sold 118 total items and earned $1,932. How many pies were sold last weekend?
Answer:
64 pies sold
Step-by-step explanation:
x = number of cakes sold
y = number of pies sold
Last weekend the bakery sold 118 total items
x + y = 118
Last weekend the bakery earned $1,932.
18x + 15y = 1,932.
Get rid of one of the terms, in this case x.
x + y = 118 becomes
18x + 18y = 2124
Subtract the equations from each other
(18x - 18x) + (18y - 15y) = 2124 - 1932
3y = 192
y = 64
Subsititue y into the orginal qeuation to solve for x and check it's right.
x + 64 = 118
x = 118 - 64 = 54
18(54) + 15(64) = 1932

Pine Hill Middle School has 300 students. In
Zoey's class, two out of five students belong to
a club. Use this ratio to predict how many
students in the school belong to a club.
There are 120 students in the school Pine Hill Middle School who belong to a club.
What is a ratio?A ratio describes a comparison between two or more quantities in simplest form.
Given that Pine Hill Middle School has 300 students.
Also given two out of five students belong to a club.
∴ We can conclude that (2/5)th of the total students belong to the club which is numerically,
= (2/5)×300.
= 120 students.
We can also solve this by ratios if in a total of 5 students 2 students belong to a club that means 3 students doesn't belong to the club and their ratio is 2:3.
∴ The no. of students belonging to the club is 2/(2+3)×300.
= (2/5)×300.
= 120 students belong to the club.

Step-by-step explanation:
Liam walked from his house to the school in 17 minutes. He arrived at the school at 7:50 a.m. Stephanie started walking 5 minutes after Liam left his house. She arrived at the school at 7:52 a.m. How long did it take Stephanie to walk to the school?
Answer:
14 minutes
Step-by-step explanation:
If Liam got to school at 7:50, and it took him 17 minutes, that means he left at 7:33. Five minutes after 7:33 is 7:38, so that's when Stephanie left. She arrived at school at 7:52 am, so what we have to do is subtract 7:38 from 7:52 in order to get 14 minutes elapsed.
