Answer:
The upper right hand corner
Step-by-step explanation:
One big clue to this is to note how the inequalities are x < 0 and x >= 2 so there is a gap of x values that are left out (x = 1 for instance). There will be NO graph points at all for any values in this gap. The only graph with such a gap is the upper right hand corner. So that is why this is the answer.
Another reason is that y = (-4/5)x-3 is a line that goes through (0,-3). Plug in x =0 and you'll get y = -3 when you simplify. There is an open hole here due to "x < 0". So x cannot actually equal zero for this part. At the same time, plug in x = 2 into the second piece and you get y = -4 as a result. So (2,-4) is on the second graph as a closed hole. The upper right hand corner has both of these points in the proper location.
Answer:
32
Step-by-step explanation:
Imagine someone is trying to put tiles on a bathroom floor - this is the situation in this question. "tiles needed to fit across the length" is asking how many 25cm tiles can fit in the length of the bathroom, which is 8m.
To do this, we need to do some conversion.
8m to cm = 800cm
800 ÷ 25 = 32
This means 32 tiles are needed to fit across the length of the bathroom floor.

Answer:
≈ 15.73 in
Step-by-step explanation:
Since the volume of a cylinder is , we can set the equation,
= 1000
Since the radius of the circle is 4.5, we square it to get
= 1000
Dividing by 20.25 on both sides, we get
≈ 49.38
Dividing by 3.14 on both sides, we get
≈ 15.73 in
10% of 500 = .1 * $500 = $50
answer: he puts $50 in his saving each week
