Answer: 13 is a rational number
Step-by-step explanation: By definition, a rational number is a number q that can be written as a fraction in the form q=a/b where a and b are integers and b≠0. So, 1/3 is rational because it is exactly what you get when you divide one integer by another.
Answer:
b
Step-by-step explanation:
9^2 + 12^2 = 225. the square root of 225 is 15. x=15
Answer: y = -5x+5
Step-by-step explanation: Slope intercept form is written as y = mx+b where m is the slope of the function and b is the y-intercept of the function. In this linear function, the line crosses the y-axis at (0,5). This is the y-intercept. We can find the slope with the (y2 - y1) / (x2 - x1) by choosing 2 points on the graph. I chose (0,5) and (1,0). If you use the formula, you will end up with -5 as your slope.

Answer:
f(2) = 36
Step-by-step explanation:
Put 2 where x is and do the arithmetic.
f(2) = 6^2
An exponent of 2 means 6 is a factor two times.
f(2) = 6×6
f(2) = 36
