Answer:
the student answer is incorrect
Correct answer: y = 109x + 5
Step-by-step explanation:
He STARTS with $5, which means it says aside. Since he REPEATEDLY recieves $109 EVERY day, it is as 109x because you don't know how much days there are. So the correct equation is y = 109x + 5.
Hope this helps!
Have a nice day!
Answer:
D. 9
Step-by-step explanation:
Let
abc=100a+10b+c
bca=100b+10c+a
cab=100c+10a+b
abc + bca + cab=(100a+10b+c) + (100b+10c+a) + (100c+10a+b)
=100a + 10b + c + 100b + 10c + a + 100c + 10a + b
Collect like terms
=100a + a + 10a + 10b + 100b + b + c + 10c + 100c
=111a + 111b + 111 c
Factorise
=111(a+b+c)
abc + bca + cab = 111(a+b+c)
Factors of 111(a+b+c)= 1, 3, 37, 111, and (a+b+c)
abc + bca + cab is divisible by a+b+c because it is a factor of 111(a+b+c)
abc + bca + cab is divisible by 3 because 3 is a factor of 111(a+b+c)
abc + bca + cab is divisible by 37 because 37 is a factor of 111(a+b+c)
abc + bca + cab is not divisible by 9 because 9 is not a factor of 111(a+b+c)
Add 6 to x^2 to translate function to the left (x+6)^2, then minus 5 to move down: (x-6)^2-5
Answer:
Step-by-step explanation:
We know that the missing angle is 45 degrees and the hypotenuse is 14.
If both side angles equal to 45, according to base angle theorem, this triangle is isosceles.
Since this triangle is isosceles, the two legs must be equal. Let x be the legs.
According to the 45 45 90 triangle theorem, the hypotenuse is equal to 
*x
If 14 = 
= x
Rationalize denominator
The answer is
