Answer:
- (x +1)² = 4
- (D) x = -1 ±2
Step-by-step explanation:
Start by getting the x-terms on one side of the equal sign. We can do that by subtracting x from both sides.
3 = x² +2x
Now, add the square of half the x-coefficient.
3 +1 = x² +2x +1
(x +1)² = 4 . . . . . . . . write as a square in the desired form
__
To solve, take the square root, and add the opposite of the left-side constant.
x +1 = ±2
x = -1 ±2 . . . . . . matches choice (D)

Answer:
Shift 8 units up
Step-by-step explanation:
The given function is;
f(x)=x
and
g(x)=x+8
The function f(x) has its y-intercept at y=0.
The function g(x)=x+8 has its y-intercept at y=8
This implies that; the linear parent function f(x)=x is shifted up 8 units to obtain g(x)=x+8.
For this case we have the following definition:
tens place: number of two digits whose absolute value is greater than zero.
Then, we have the following rounding rule:
If the previous number is greater than or equal to five, the next number increases by one unit.
We then have the following numbers rounded to 30 when rounded to the nearest ten:
26: twenty-six
27: twenty-seven
Answer:
two different numbers that round to 30 when rounded to the nearest ten are:
26: twenty-six
27: twenty-seven
