Answer:
x = 15
Step-by-step explanation:
I am going to use the "butterfly" method for proportions
(there is another type of butterfly method that is different, I am not sure if there is another name for this method, sorry!)
Multiply the:
- top left by the bottom right
-the top right by the bottom left
and then:
- set them equal to each other
So we will <u>multiply 7 by x and 21 by 5</u> (if this doesn't make sense tell me and I will explain it even more!)
7x = 21 * 5
7x = 105
(Divide both sides by 7) <em>x = 15</em>
Hope this helps, have a nice day! :D <3
Answer: J. A translation of △XYZ to the right.
Step-by-step explanation:
I'll explain each bullet point one by one. A good hint is to pay attention to where the letters are.
-J is correct because the figure was shifted to the right.
-K is incorrect because if it was a reflection across the x-axis, the figure would be in Quadrant 3, or the bottom left.
-L is incorrect because if you pay attention to the letters, they are in the exact same place. If it was a reflection across the y-axis, the X' and Y' would switch places if you know what I mean.
-M is incorrect because if the figure was rotated 90°, point Z' would be furthest from the x-axis. In other words, the triangle would have been pointing up and not down.
-N is incorrect because if the figure was rotated 180° clockwise, the figure would have been in Quadrant 4, or the bottom right.
Given this information, the most appropriate answer is J.
I hope this helps! Pls give brainliest!! :)
Answer:
Maria sent 7 messages
Bob sent 5 messages
Ahmad sent 45 messages
Step-by-step explanation:
Given that Maria, Ahmad, and Bob sent a total of 52 text messages during the weekend.
If Maria sent fewer messages than Bob, and Ahmad sent times as many messages as Bob
Since the exact figures were not given, then let make an assumption that Ahmad sent 9 times as many messages as Bob.
If Bob sent 5 messages, then, Ahmad will send 5 × 9 = 45 messages
Also, it is given that Maria sent fewer messages than Bob. Take 45 away from 52. That is,
52 - 45 = 7
Therefore,
Maria sent 7 messages
Bob sent 5 messages
Ahmad sent 45 messages

Answer:
see attached
Step-by-step explanation:
A graphing calculator can do a nice job of showing you what the graph looks like.
The initial factor of 4 is the value when x=0, the y-intercept. The base of 2 tells you the function value is multiplied by 2 for each unit of x to the right, and divided by 2 for each unit of x to the left. (The curve quickly goes off the top of the graph.)
The horizontal asymptote is y=0, as it is for all exponential functions (that have not been translated).
Answer:
x=8
Step-by-step explanation:
X=8 because 39/3 is 13 and 13- 5 is 8 and 5 and 8 add up to make 13 inside the parenthesis.
