Answer: A translation and a reflection
Step-by-step explanation:
Hello! So a number squared has to do with a number multiplied by itself to get a number. If you know basic multiplication, 7 * 7 is 49. The square root is like that. The number raised to the 2nd power to get that number. In this case, the square root of 49 is 7.
Multiply first equation by -5 and 2nd by 2, add them
15x+20y=-100
<u>2x-20y=32 +</u>
17x+0y=-68
17x=-68
divide both sides by 17
x=-4
the x value is -4
Answer:
Option b.
Step-by-step explanation:
Consider the below figure attached with this question.
A computer program selects blue,red,green as the background color each time the program is used.
Blue background = 12 times
Red background = 21 times
Green background = (45-12-21) times = 12 times
Blue background = Green background
Red background ≠ Green background
Green is just as likely as blue to appear, but not as likely as red.
Therefore, the correct option is b.
