Answer:
(x + 2)^2 - 11.
Step-by-step explanation:
f(x) = x^2 + 4x - 7
Now x^2 + 4x = (x + 2)^2 - 4 so we have:
f(x) = (x + 2)^2 - 4 - 7
f(x) = (x + 2)^2 - 11.
Answer:
0
Step-by-step explanation:
Slope = rise/run = 0/9 = 0
Answer:
60x + 42y
Step-by-step explanation:
6(10x + 7y)
Use distribute property and multiply 6 to everything inside the parenthesis:
6 x 10x = 60x
6 x 7y = 42y
SO, 60x + 42y is the correct answer
Answer:
there is no solution for (0, 30°)
Step-by-step explanation:
six(x) = cos(x)
sin(x) - cos(x) = 0
(sin(x) - cos(x))^2 = 0
sin(t)^2 + cos(x)^2 - 2sin(x)cos(x) = 0
1 - sin(2x) = 0
sin(2x) = 1
2x = π/2 + 2πk -> k - any integer number
x = π/4 + πk
the smallest positive solution is π/4 = 45°. That means for range (0, 30°)
there is no solution
