Answer:
- 5
Step-by-step explanation:
Step 1:
4 ( 2y + 1 ) = 2 ( y - 13 )
Step 2:
8y + 4 = 2y - 26
Step 3:
6y + 4 = - 26
Step 4:
6y = - 30
Answer:
y = - 5

Answer:
Step-by-step explanation:
f(x) = 3x^2 + 6x + 3
a of s: -6/6 = -1
3(-1)^2 + 6(-1) + 3
3 - 6 + 3
-3 + 3 = 0
(-1,0)
answer is A. the first one
Let this number be x.
"Six less than seven times a number is equal to -20" can be represented by the equation 7x - 6 = -20. We need to solve for x.
First, add 6 from each side so we can have the variables on a side and the numbers on the other:
7x - 6 + 6 = -20 + 6
7x = -14
Then, you divide each side by 7 so we can get the variable x alone on a side, and its value on the other side:
(7x)/7 = -14/7
x = -2
You can re-check your answer (very important):
7x - 6 = 7 (-2) - 6 = -14-6 = -20
The answer has been approved.

Answer:
= - 14 - 4√5/ 29
Step-by-step explanation:
(√3-√5)(√5+√3)/7-2√5
= √15 + 3 - 5 - √15/7 - 2√5
= - 2/7 - 2√5
= - 2/7 - 2√5 x 7 + 2√5/7 + 2√5
= - 14 - 4√5/49 + 14√5 - 14√5 - 20
= - 14 - 4√5/ 29
