Answer:
B
Step-by-step explanation:
Looking at the graph we can see that the function is increasing -4<x<-2 and 0<x2
The graph is increasing when it is going upwards, or has a slope greater than 0
We can see that happening in two places in the function, which are the intervals of the x coordinate in B
Answer:
1) Three increased by a number: 3+x
2) The sum of nine and eight: 9+8
3) Nine divided by a number: 9/x
4) The sum of nine and a number : 9+x
5) A number divided by 9: x/9
6) Nine less than a number: x-9
7) The product of nine and a number: 9n
Step-by-step explanation:
You have to match statements with their mathematical expressions.
I will match the statements with their mathematical forms.
1) Three increased by a number: 3+x
2) The sum of nine and eight: 9+8
3) Nine divided by a number: 9/x
4) The sum of nine and a number : 9+x
5) A number divided by 9: x/9
6) Nine less than a number: x-9
7) The product of nine and a number: 9n

Answer:
x=7
Step-by-step explanation:
if you look at this diagram as 2 triangles, the little one, and then the big one that the little one is inside of, and realize that they are similar triangles (by AAA standards) you can use a ration to solve the answer. the side length 9 is the length that is similar to side length 21, so you put those in a fraction format (9/21), and side length 3 is similar to side length x so you put those in a fraction (3/x), and then you create a ration with those
9/21=3/x
now you can cross-multiply 21 times three (63) and divide that number by 9 (7) to get your final answer of x=7.
Hope this helps!
