use the function rule f(x)=x * |-1|^x. find the output f(2).
A.4
B.3
C.-2
D.2
1. 2
2. D
3. D
4. No
5. y=1/2 x +6
-1^2 = 1
so f(2) = 2*1
= 2. (by multiplication)
The last one is b
1.c, 39,48,57
2.b, geometric
3.d,15,45,135,405
4.d, 2
5.d, graph d
6.d, no
7.b, y=2x-6
Mary is correct! The last one is B but all of NM’s other answers were correct
My answer would be A
If yours also has 7 questions then NM is incorrect
What about the way to solve the problem instead of just the answer
Sure, let me provide the explanations:
1. What integers from 30 to 60 are divisible by 3?
The multiples of 3 are 33, 36, 39, 42, 45, 48, 51, 54, and 57. Therefore, there are 9 integers from 30 to 60 that are divisible by 3.
2. Which sequence is an example of a geometric sequence?
A geometric sequence is formed by multiplying the previous term by a constant. Based on the given sequences, only sequence B has a common ratio of 3 and is therefore geometric.
3, What are the next two terms in the sequence 5, 15, 45, 135, ….?
To find the next terms of this sequence, we need to multiply each term by 3. That is, the next two terms are 405 and 1215.
4. If Emily has 8 cats and gives away 3 cats, how many does she have now?
Emily has 5 cats after giving away 3.
5. Which of the following graphs represents a proportional relationship between x and y?
Graph D represents a proportional relationship between x and y as it is a straight line passing through the origin.
6. Is a square a rhombus?
A square is a special case of a rhombus where all four sides are equal in length and all angles are right angles.
7. What is the equation of the line with slope 2 and y-intercept -6?
The equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. Therefore, the equation of the line is y = 2x - 6.
