Which transformations could have taken place to map △ABC to △A"B"C"?
A. a reflection and a dilation
B. a rotation and a dilation
C. a translation and a dilation
D. a reflection and a translation
Answers
Answer:
C. A translation and a dilation
Step-by-step explanation:
Of course it has to be a dilation as the size is obviously different. So that takes D out of the question. The angles are in the same spots as B is still at the highest on both triangles and so does A. Which means it just translated (moved/slide) to the right and up a bit.

Step-by-step explanation:
When x < 1, y = 1, which is a horizontal line. This eliminates the last 2 options because the red line (which represents x < 1) is not a horizontal line. However, if we look at the second option, we see that the red line is y = 2, not y = 1, and therefore the answer is A. Hope this helps!

y = mx + b
Where m is the rate of change and b is the intial value of y.
Let x represents the activity level and y represents the number of meals eaten. Given that:

For an activity level of 9 (x = 9):
y = 0.23(9) + 4.1 = 6.17
If a cat had an activity level of about 9, then it's likely to have eaten about 6 meals.

Colin rolls a fair dice 18 times.
How many times would Colin expect to roll a number greater than 3?
Answers
Answer:
8 or 1/2
Step-by-step explanation:
The requried probability that colin expects to roll a number greater than 3 is 1/2.
What is probability?Probability can be defined as the ratio of favorable outcomes to the total number of events.
Here,
Colin rolls a fair die 18 times.
The total outcome of 1 die = 6
So, for 18 die total outcome = 6 × 18
Now,
Favorable outcome = 4, 5, 6 = 3
A total favorable outcome for 18 dice = 3 × 18
Probability, many times would Colin expect to roll a number greater than 3.
= 3 × 18 / 6 × 18
= 1 / 2
Thus, the requried probability that colin expects to roll a number greater than 3 is 1/2.

What is the first step to solve this equation: 3x =44
Answers
You need to divide 3 on both sides
The correct first step to solve the equation 3x = 44 is to divide both sides by 3.
To solve the equation 3x = 44, the first step is to isolate the variable x on one side of the equation.
To achieve this, you need to undo the multiplication by 3 on the left side of the equation.
Since 3x means 3 multiplied by x, you need to divide both sides of the equation by 3.
By dividing both sides of the equation by 3, you are essentially canceling out the effect of the multiplication by 3 on the left side.
This step allows you to isolate the variable x.
So, the correct first step to solve the equation 3x = 44 is to divide both sides by 3.
Hence the correct option is 4th.
