The estimate should be 6.92
Answer:
x = 3
y = 2
Step-by-step explanation:
Diagonals of a parallelogram bisect each other into two equal segments. Therefore:
3x - 1 = 2(x + 1)
Solve for x
3x - 1 = 2x + 2
Collect like terms
3x - 2x = 1 + 2
x = 3
Also:
5y + 1 = 6y - 1
Collect like terms
5y - 6y = -1 - 1
-y = -2
Divide both sides by -1
y = -2/-1
y = 2
Answer:
(-1, 19) and (3, -81)
Step-by-step explanation:
f(x) = 2x³ − 6x² − 27x
f'(x) = 6x² − 12x − 27
-9 = 6x² − 12x − 27
0 = 6x² − 12x − 18
0 = x² − 2x − 3
0 = (x + 1) (x − 3)
x = -1 or 3
f(-1) = 19
f(3) = -81
The points are (-1, 19) and (3, -81).
Answer- (5x-1)(2x+1)
let me know if you need to see work
On the number line, move 4 units to the right. End at -2. The dolphin was 2 feet below sea level.
<h3>What is number line?</h3>
A number lines are the horizontal straight lines in which the integers are placed in equal intervals.
A dolphin was swimming 6 feet below sea level. It then swam up 4 feet.
So, -6+4= -2 feet
As, from the information
On the number line, move 4 units to the right. End at -2. The dolphin was 2 feet below sea level.
This is because the dolphin 6 feet below sea level and swam up 4 feet.
