Answer:
Instead of moving the 3x to the opposite side of the equation they moved the 2x. And the correct answer is x=-6 not x=6.
Step-by-step explanation:
Student Work:
2(x + 4) – 8 = 3x+10-4
2x + 8–8 = 3x + 6
2x = 3x + 6
- 3x – 3x
X = 6
My work:
2(x+4)-8=3x+10-4
2x+8-8=3x+6
2x=3x+6
-x=6
x=-6
There would be only one.
because 1/2 only can only go into 3/4 one time as 2/4ths
SO the answer will be 1.
Answer:
4
Step-by-step explanation:
The sum of the first n terms of a geometric series is:
S = a₁ (1 − rⁿ) / (1 − r)
Given S = 15624, r = 5, and n = 6:
15624 = a₁ (1 − 5⁶) / (1 − 5)
a₁ = 4
Answer:
The vertex is (−3, −1), the domain is all real numbers, and the range is y ≤ −1
Step-by-step explanation:
f(x) = −2(x + 3)^2 − 1
The vertex form is
f(x) = a ( x-h) ^2 + k where ( h,k) is the vertex
f(x) = −2(x - -3)^2 − 1
The vertex is ( -3,-1) is the vertex
The domain is the values that x can take and x can take all real numbers
The vertex is the maximum since a is negative so the range is all values less than -1
y ≤ −1
