given cos theta is equal to - 4/ 7 then we can conclude that theta is in the second and third quadrants. In this case, the other leg is equal to square root of (7^2 - 4^2 ) equal to square root of 33. In this case, sin theta can be equal to +- square root of 33 / 7 and tan theta is equal to +-square root of 33 / 4.
F(-5) = 2(-5)² + 3(-5) + 7
f(-5) = 2(25) - 15 + 7
f(-5) = 50 - 8
f(-5) = 42
The solution will be a number line from negative 5 to 5 in increments of 1. An open circle is at 3 and a bold line starts at 3 and is pointing to the right.
<h3>Inequality expression</h3>
Inequalities are equations that are separated by an equal sign. Given the inequality expression
3(8 – 4x) < 6(x – 5)
Expand
3(8) - 3(4x) < 6x - 6(5)
24 - 12x < 6x - 30
Collect the like terms
-12x - 6x < -30 - 24
-18x < -54
x > 3
Hence the solution will be a number line from negative 5 to 5 in increments of 1. An open circle is at 3 and a bold line starts at 3 and is pointing to the right.
