Answer:
no
Step-by-step explanation:
y = 9x − 5
The point (0,0) means x=0 and y=0
Substitute this into the equation and see it is true
0 = 9*0 -5
0 = 0-5
0 = -5
This is not true so the point is not a solution.
Answer:
-7
Step-by-step explanation:
(7/8)(-16)(-7)(-1/4)
(7/8)(-1/4)(-16)(-7)
(-1/16)(112)
-7
Answer:
(-4, 5)
Step-by-step explanation:
Since the pint is reflected over the y-axis, its y-coordinate remains the same.
Point (4, 5) has 4 as its x-coordinate. That is 4 units right of the y-axis. The reflection has -4 as its x-coordinate which is 4 units left of the y-axis.
Answer: (-4, 5)
Baseball cards
We know two things:
Gaetano had 52 cards on 3 years
Gaetano had 108 cards on 7 years
Then, from the fourth year to the seventh year he added
108 - 52 = 56 cards
In four years he added 56 cards. Then each year he added
56/4 = 14 cards
Since
14 * 3 = 42
On the first three years he added 42 cards to his collection.
Then he started with
52 - 42 = 10 cards
Answer: Gaetano started his collection with 10 cards and he adds 14 new cards to it each year
