Answer:
x=6
Step-by-step explanation:
3x-7=5x-19
12=2x
x=6
Step-by-step explanation:
9) C
10) B
11) (b-5)(b+8)
12) (7w - 2)²
13) 14(5x + 2)(3x - 1)
14) (4h - 1) and (h + 6)
15) 3 and (a - 2) and (a + 8)
16) 5 and (4w - 1) and (w + 2)
The tenth place is the number on the right of the decimal which is
6703.58
So to round to the nearest tenth, look at the number before it, which is 8. The rule for rounding: 5+ = round up, 4 or less = keep as same number
8 is a number that is 5+ so we round 5 (number in the tenths place) up one number
6703.6
First, you need to find out how many zippers are used to make one bookbag. To do that, you divide the zippers used to make the 3 backpacks.
12 / 3 = 4
So, 4 zippers are used per bookbag. Then, you divide the number of available zippers by four to find out how many bags she can make.
48 / 4 = 12
Roberta can make 12 bookbags.
Answer:
Inverse of f exists.
Step-by-step explanation:
From the graph attached,
If we do the horizontal line test for the function graphed,
We find the function as one to one function.
In other words for every input value (x-value) there is a different output value.
Since, for one-to-one functions, inverse of the functions exist.
Therefore, the answer will be,
The inverse of 'f' exists.
