Answer:
B) Only (-3, 5)
Step-by-step explanation:
Slot in the options into the equation
(-2, 4),
Compare with (x, y)
x = -2, y =4
y =-3x - 4
4 =( -3 * -2 ) - 4
4 = 6 - 4
This is not true hence, option A is wrong
Using (-3, 5)
x = -3, y= 5
5 = (-3*-3) - 4
5 = 9 - 4
This is correct hence, option B is correct
Option c is wrong because (-2,4) is not a solution to the equation
Option D is wrong because option B is correct
The answer would be 90 I think
You did #1 correctly.
#2). The question gives you the equation, and the numbers to use for 'a' and 'b', and it just wants you to plug in those numbers and do the arithmetic.
It says: The number of tiles needed is (a²) divided by (b²).
Then it says: a = 96 and b = 8. I know you can handle that !
Number needed = (96)² divided by (8)² .
Use your calculator:
(96)² = 9,216
(8)² = 64
Number needed = (9,216) divided by (64) = 144 tiles
#3). While reading #3 carefully, I realized that there's a table printed near it,
and you need the table to do the problem. But you can't see the table in the
picture, so we're stuck on this one.
Answer:
Step-by-step explanation:
2.5 / 2
Assuming the object moving on the circular path is the point on the edge of the wheel, the distance it travels in one minute is
5*(2π*(10 in)) = 100π in
The linear speed is 100π in/min ≈ 314.16 in/min.
