138 is divisible by 3 because if you add each integer: 1 + 3 + 8, you get 12. If 12 number is divisible by 3, than the whole number is. Since it is, 138 is divisible by 3.
1x10^-5 Answer =2 x 10^9
2x10^-4
Simple, take 3 1/2 turn it into a decimal which = 3.50 since
1/2 = 0.5 because 1 divide by 2 = 0.5
Same thing for 1 1/4 = 1.25 since
1/4 = 0.25 because 1 divide by 4 = 0.25
3.50 divide by 1.25 = 2.8 miles one hour.
f(x) = 4x + 3
That's one-to-one, a linear function that will give a different f(x) for each different x.
For the inverse let's swap x and y and solve for y
x = 4y + 3
x - 3 = 4y
y = (x- 3)/4
That's the inverse,
Answer: (x- 3)/4, second choice
The domain and range of the inverse is all real numbers. It's two lines; I'll leave the graphing to you.
Answer:
6x-18
Step-by-step explanation:
First we multiply everything in the parentheses by 3
3×2x=6x
3×(-6)=-18
And now we put it together-
6x-18
