The third option, a rational number
like 1/5 + 2.5 is still rational (but neither irrational nor whole/an integer)
it would be 0.2 + 2.5 = 2.7 btw
or
1/5 + 5/2
= 2/10 + 25/10
= 27/10

Which greatest digit should replace n so that the number 342n84 is divisible by 3?
Answers
Answer:
9
Step-by-step explanation:
If you want the number to be divisible by three make sure the sum of all the numbers are divisible by three. Add all the numbers you have to see what they make.
3+4+2+8+4=21
So we just need to find the greatest number we can add to that to have it remain divisible by three. A number divisible by three is 30, and we can add 9 to 21 to make 30. Of course, there are other numbers we could add, but nine is the largest one-digit number that would work. Other smaller numbers include 3 and 6.
3+4+2+8+4+9=30
Now we check to see if our number is divisible by three
342984÷3 = 114328
114328 is a whole number so we know it's divisible.

Answer:
see below
Step-by-step explanation:
The x-values in each table are evenly-spaced (increasing by 2). So, the quadratic function can be identified by its second differences: they will be a non-zero constant.
Table 1 has first differences that are constant at 3. -2-(-5) = 3, for example. It represents a linear function.
Table 2 has first differences of 4, 8, 4, 4, neither constant, nor linearly increasing. The function does not have a name.
Table 3 has first differences of -9, -3, +3, +9, and these have differences of +6. This represents a quadratic function.
Table 4 has first differences of 0.5, 1, 2, 4. These have a constant ratio, as do the values in the table. It represents an exponential function.
The table that represents a quadratic function is C. Table 3.
What is a quadratic function?A quadratic function simply means a function that's in the form of f(x) = ax² + bx + c.
In this case, the table that represents a quadratic function is table 3. It has first differences of -9, -3, +3, +9, and these have differences of +6. It can be deduced that in the quadratic function, b and x are numbers.

Answers
Answer: (below)
Step-by-step explanation:
The functions shown are exponential functions, which have the form f(x) = a*(b)^x. "a" represents the intial value, while "b" represents the growth factor.
To determine whether a function is growing or decaying, you look at the growth factor. If the growth factor is greater than 1, the function is growing, since each value is getting larger and larger. Meanwhile, if the growth factor is between 0 and 1, the function is decaying, since each value is getting smaller and smaller.
Now, back to this question, let's look at our functions. In the function on the left, the growth factor is 0.87, which is between 0 and 1, so this function is decaying. For the function on the right, the growth factor is 1.25, which is greater than 1, so this function is decaying. Next, let's look at our graphs. In the left graph, the function is growing, so it matches with the function on the right. Meanwhile, in the right graph, the function is decaying, so it matches with the function on the left.
Hope this helps!

Answers
Answer:
b = 5
Step-by-step explanation:
3b - 4 = 11
Add 4 to each side
3b - 4+4 = 11+4
3b = 15
Divide each side by 3
3b/3 = 15/3
b = 5
Answer:
b = 5
Step-by-step explanation:
3b - 4 = 11
3b - 4 + 4 = 11 + 4
3b = 15
3b ÷ 3 = 15 ÷ 3

Explanation:
SkippingSkippingCorresponding angles are ones where they are in the same configuration of the 4 corner angle set up. Angles A and E are in the same northwest position. Another pair would be angles B and F in the northeast, and so on. Corresponding angles are congruent when we have parallel lines like this.Vertical angles form when we cross two lines. They are opposite one another and always congruent (regardless if the lines are parallel or not).Alternate interior angles are inside the parallel lines, and they are on alternating sides of the transversal cut. Alternate interior angles are congruent when we have parallel lines like this. Alternate exterior angles are the same idea as number 5, but now we're outside the parallel lines. Alternate exterior angles are congruent when we have parallel lines like this.Adjacent angles can be thought of as two rooms that share the same wall. Specifically, adjacent angles are two angles that share the same segment, line, or ray. The angles must also share the same vertex. In this case, any pair of adjacent angles always adds to 180 (though it won't be true for any random pair of adjacent angles for geometry problems later on).Simply list any angle that looks obtuse, ie any angle that is larger than 90 degrees.List any angle that is smaller than 90 degrees. It can be adjacent to whatever you picked for problem 8, but it could be any other acute angle as well.Refer to problem 7. In this case, adding any two adjacent angles together forms a straight line.Suppose you want to save $1000 for a down payment on your first car purchase. You have $750 right now.

Expression by the student :
Expression 1 :

The expression 1 is equivalent to the expression on the board. Because the coefficients of x and y are same on both.
Expression 2 :
[tex]2 ( 6.1x + 25.3 y + 2.1x -3.9y)\\\\= 2 ( 8.2x + 21.4y)\\\\=( 2 \times 8.2x ) + (2 \times 21.4y)\\\\= 16.4x + 42.8y[/tex]
The expression 2 is also equivalent to the expression on the board. Because the coefficients of x and y are the same.
