The age of the van owned = 12 years
The age of the truck owned = 29 years
Step-by-step explanation:
Here, the given question is INCOMPLETE.
Laura takes very good care of her vehicles. She owns a blue van and a red truck. Although she bought them both new, she has owned the truck for 17 years longer than she has owned the van. If the sum of the ages of the vehicles is 41 years, how old is the van and how old is the truck?
Let us assume the number of years Laura has owned the van = S years
So, according to the question:
The number of years she has owned truck = S + 17 years
Now, Sum of the age of ( Truck + Van) = 41 years
⇒ (S + 17 years) + (S years) = 41 years
or, 2 S + 17 = 41
or, 2 S = 4 1 -1 7 = 24
or, S = 24/2 = 12 years
or, S = 12 years
Hence the age of the van owned = 12 years
The age of the truck owned = S + 17 = 12 + 17 = 29 years
Answer: The least score she can get on her next test is 455 points.
Step-by-step explanation: From the available information, her current mean score is 88%, and that was achieved from a total of 5 tests. Hence, her mean score was computed as follows;
Mean = (Summation of data)/observed data
Where the observed data is 5 and the mean is 88. Therefore the mean can now be expressed as,
88 = Summation of data/5
By cross multiplication we now have
88 x 5 = Summation of data
440 = Summation of data.
So, if she wants to raise her mean score on her next test to 91%, her least possible score would be derived as
91 = (Summation of data)/5
By cross multiplication we now have
91 x5 = Summation of data
455 = Summation of data
Therefore, on her next test, she must score at least 455 points.

Step-by-step explanation:
Given


Solving (a): Reflect S across y-axis
The rule to reflect across y-axis is:

So, we have:

Hence:

Solving (b): Reflect Q across x and y-axis
The rule to reflect across x-axis is:

So:

The rule to reflect across y-axis is:

So:

Hence:
