Answer:
C and D
Step-by-step explanation:
Given
(3x - 5)² = 19 ( take the square root of both sides )
3x - 5 = ± ( add 5 to both sides )
3x = ± + 5 ( divide both sides by 3 )
x =
x = → C
x = → D
Statements Reason
1. Given
2. Division property of equality
" Division property of equality states that if we divide both sides of an equation by the same nonzero number, the equation remains equal".
3. Simplifying
4. Addition property of equality
"Addition property of equality states that if the same number is added to both sides of an equation, then the equality is still true".
5. Simplifying
Therefore, the solution to the equation is x = -3.
Answer:
Yes
Step-by-step explanation:
a=1
b=3
c=2
d=4
The answer is 3/2 because you do the slope equation and that answer
Answer:

Step-by-step explanation:
To obtain a term in the sequence add the previous 2 terms, that is
= + ← in general terms
(a)
Given 1 4 5 9 14
Then the next 2 terms are 9 + 14 = 23 and 23 + 14 = 37
(b)
Given a₄ = 30 and a₅ = 49 , then
a₃ = 49 - 30 = 19
a₂ = 30 - 19 = 11
a₁ = 19 - 11 = 8
Sequence is 8 11 19 30 49 ....
(c)
Given a₂ = x and a₃ = y , then
a₁ = y - x
a₄ = a₃ + a₂ = y + x
a₅ = a₄ + a₃ = y + x + y = 2y + x
