Step-by-step explanation:
Answer:
-20xy -8y+26
Step-by-step explanation
First Multiply 2 by 3.
6 + 10 x 2 - 4 x (2y) - 20xy
Then Multiply 10 by 2.
6+20-4x(2y)-20xy
After that Multiply 2 by -4.
6+20-8y-20xy
Lastly add 6 and 20.
26 -8y -20xy
Answer:
approximately 8.16 times
Step-by-step explanation:
Answer:
(1,0)
(-2,3)
(5,24)
Step-by-step explanation:
To solve this you can can just plug in the x and y values and see which work
y = x²-1
Lets test (0,1):
1 = 0²-1
1 = -1
This pair <em>does not</em> work, because 1 does not equal -1
Lets test (1,0):
0 = 1²-1
0 = 0
This <em>does</em> work, because 0 equals 0
Lets test (3,5):
5 = 3²-1
5 = 9 - 1
5 = 8
This pair <em>does not</em> work, because 5 does not equal 8
Lets test (5,24):
24 = 5²-1
24 = 25 -1
24 = 24
This pair <em>does</em> work, because 24 equals 24
Lets test (-2,3):
3 = (-2)²-1
3 = 4-1
3 = 3
This pair <em>does</em> work, because 3 equals 3
Lets test (-4,-17):
-17 = (-4)²-1
-17 = 16 - 1
-17 = 15
This pair <em>does not</em> work, because -17 does not equal 15
So the pairs that are on the graph are:
(1,0)
(-2,3)
(5,24)
Answer:
-11 for the first one and 0 for the second one
