Answer:
The correct option is B.
Step-by-step explanation:
We know, from the definition of |x|,
|-8x| = - 8x, when - 8x ≥ 0 i.e. x ≤ 0 ......... (1)
and |-8x| = 8x, when - 8x < 0 i.e. x > 0 .......... (2)
Now, for x ≤ 0 {i.e. condition (1)}
- 8x ≤ 8, ⇒ x ≥ - 1 ......... (3)
Again, for x > 0 { i.e. condition (2)}
8x ≤ 8, ⇒ x ≤ 1 .......... (4)
So, combining conditions (3) and (4) we get -1 ≤ x ≤ 1.
So, the correct option is B. (Answer)
Answer:
9 3/4 pages = x
Step-by-step explanation:
change 3 1/4 to a decimal
working with the fraction
3 1/4 /8 = x/ 24
3 1/4 (24) = 8x
13/4 (24) = 8x
316/4 = 8x
78 = 8x
78/8 = x
9 3/4 = x
Hello! To find the answer to these problems, we need to divide the price by the quantity bought. For example, if you buy 4 erasers for $2, you would do 2/4 to find the cost per eraser. When you divide all of the items correct, these are the unit prices you get:
tote bags: $1.96
picture frames: $2.15
water bottles: $2.30
mugs: $1.99
t-shirts: $2.50
Okay. So we are looking for the souvenirs that cost less than $2.25. 1.96, 2.15, and 1.99 are all less than 2.25, while 2.3 and 2.5 are more than 2.25. Therefore, tote bags, picture frames, and mugs are the souvenirs that cost less than $2.25.
Answer:
9
Step-by-step explanation:
First off you need to find the interval that four falls in.
Four is not less than three so you can rule out the first one, four is not greater than 10 so you can rule out the last one. But four is greater than three and less than ten, so it falls in the second interval.
So, now you can substitute four in for x for the second equation
4^2-7
16-7
