(-2,-4)
a) The zero of line s is 6
c) the slope of line s is 1/4
b) the x-intercept of line s is-3
d) The graph passes through the
Point -8,4
Step-by-step explanation:
The graph of linear functions passes through the points (10,2) and
(-2,-4)
a) The zero of line s is 6
c) the slope of line s is 1/4
b) the x-intercept of line s is-3
d) The graph passes through the
Point -8,4
600,000 pound = 300 tons
3 * 10^n = 300
10^n = 100
10^2 = 100
so n = 2
12 to the second power is equal to 144
(12 x 12)
F(x) = x² + 4x + 10
f(x) - 10 = x² + 4x
perfect square:
x² + 4x + 4 ⇒ (x + 2)²
(x + 2)² = x(x+2) + 2(x+2) = x² + 2x + 2x + 4 = x² + 4x + 4
f(x) - 10 + 4 = x² + 4x + 4
f(x) - 6 = (x+2)²
f(x) = (x+2)² + 6

It tells you that over these intervals the balloon is going at a constant speed.
