Answer:
No
Step-by-step explanation:
Rational numbers are those that can be represented in a fraction form.
2.12359.... cannot be represented in a fraction form.
So, it is NOT a rational number
Answer:
x = 14.2 y=15.
Step-by-step explanation:
-3x<9. The way to figure this out is to divide by -3 to get x by itself. Remember, when dividing by a negative, you need to flip the inequality sign.
x>-3 is your answer.
I hope this helps!
Answer:
7b, 8a
Step-by-step explanation:
using the equation y=m(x)+b, m(x) is the slope, and b is the y intercept. Oky so for 7, its a slope of negative 2, and it has a y-intercept of 5, and if you look at graph b a slope of -2 and would be a y-intercept of 5.
looking at equation a, its a Quadric function, f(x)=x^2, but it doesn't match the graph... strange because the graph for that equation would look like the image included. Hopefully this helps!
Answer:
= 2n + 3
Step-by-step explanation:
This is an arithmetic sequence with nth term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 5 and d = 2 , then
= 5 + 2(n - 1) = 5 + 2n - 2 = 2n + 3
