Answer:
A. - 4
Step-by-step explanation:
f(4) = 4(4) - 20 = 16 - 20 = - 4
Her number was 981,543. I know because i put it from least to greatest.
It's 10 unless it's about something else
Answer:
(x+6)^2 + y^2 = 1 then isolate y^2 by subtracting (x +6)^2 from both sides, we get
y^2 = 1 - (x + 6)^2
expanding the right side, we now have
y^2 = 1-(x^2 + 12x +36)
y^2 = 1-x^2-12x -36
y^2 = -x^2 -12x - 35 therefore the solution is choice A
Step-by-step explanation:
The straight line distance from the starting point is 41 miles.
<u>Explanation:</u>
Given:
Distance covered towards north, n = 9 miles
Distance covered towards east, e = 40 miles
Distance from the origin to the end, x = ?
If we imagine this, then the route forms a right angle triangle
where,
n is the height
e is the base
x is the hypotenuse
Using pythagoras theorm:
(x)² = (n)² + (e)²
(x)² = (9)² + (40)²
(x)² = 1681
x = 41 miles
Therefore, the straight line distance from the starting point is 41 miles.
