Plug in x-values and see which one has an incorrect y value.
(x, y)
x=0; y=0+7=7; CORRECT
x=2; y=2+7=9; INCORRECT
x=9; y=9+7=16; CORRECT
x=12; y=12+7=19; CORRECT
The point that is not on the online is (9, 16).
Option b. -2 is the output of the function
Answer:
π
Step-by-step explanation:
π(9√6)³
=π81*6*√6
=(486*)√6π
=648√6π
Answer:
(-2,3)
Step-by-step explanation:
4x+5y =7
y = 3x+9
Substitute the second equation into the first equation
4x +5(3x+9) = 7
Distribute
4x + 15x + 45 = 7
Combine like terms
19x +45 =7
Subtract 45 from each side
19x +45-45 = 7-45
19x = -38
Divide by 19
19x/19 = -38/19
x = -2
Now we need to find y
y = 3x+9
Putting in x=-2
y = 3(-2) +9
y = -6 +9
y = 3
(-2,3)
Answer:
100
Step-by-step explanation:
We have the sum of first n terms of an AP,
Sn = n/2 [2a+(n−1)d]
Given,
36= 6/2 [2a+(6−1)d]
12=2a+5d ---------(1)
256= 16/2 [2a+(16−1)d]
32=2a+15d ---------(2)
Subtracting, (1) from (2)
32−12=2a+15d−(2a+5d)
20=10d ⟹d=2
Substituting for d in (1),
12=2a+5(2)=2(a+5)
6=a+5 ⟹a=1
∴ The sum of first 10 terms of an AP,
S10 = 10/2 [2(1)+(10−1)2]
S10 =5[2+18]
S10 =100
This is the sum of the first 10 terms.
Hope it will help.
