Opposite angles are equal in parallelogram
- 7x-4=5x+12
- 7x-5x=12+4
- 2x=16
- x=8
<M:-
I think its A, If I'm wrong let me know.
Answer:
2. a1 = 10 and an = a(n-1) + 2
Step-by-step explanation:
10 is our first term so it would be a of 1.
Then, in this arithmetic sequence, it is increasing by 2.
So, therefore our recursive formula for this arithmetic sequence would be:
a(n) = a(n-1) + 2
Answer:
D
Step-by-step explanation:
You have to be careful that you treat 21 as special. It is the only positive number. As you do the problem, keep an eye on 21.
f(-2) = 3x^2 - 2x + 5 Put -2 wherever you see an x
f(-2) = 3(-2)^2 - 2(-2) + 5 Calculate the first term.
f(-2) = 3(4) - 2(-2) + 5 Remove the brackets of the second term
f(-2) = 12 + 4 + 5 Combine
f(-2) = 21
Answer:
(0,5/2) y intercept
(15/7,0) x intercept
Step-by-step explanation:
To find the y intercept, let x = 0 and solve for y
0 - 6y = -15
Divide each side by -6
y = -15/-6
y = 5/2
(0,5/2)
To find the x intercept, let y = 0 and solve for x
-7x - 0 = -15
Divide each side by -7
-7x/-7 = -15/-7
x = 15/7
(15/7,0)
