What value of x makes f(x) = -2 if f(x) = 3.4x - 7.1
1 answer:
Option C
For x = 1.5 we get f(x) = -2
<em><u>Solution:</u></em>
Given function is:
We have to find the value of "x" so that f(x) = -2
Substitute f(x) = -2 in given function
Solve for "x" by moving the constants to one side and variables to other side
For x = 1.5 we get f(x) = -2
We can verify by substituting x = 1.5 in given function
Thus for x = 1.5 we get f(x) = -2

Applying the sine ratio and law of sines, the correct measurements are:
B. m∠B = 15°
E. h ≈ 31.28 ft.
<h3>What is the Sine Ratio?</h3>Sine ratio that can be used to determine the side length of a right triangle is, sin ∅ = opposite side/hypotenuse.
Find c using the law of sines:
C = 33°
A = 180 - 48 = 132 [linear pair]
B = 180 - 33 - 132 = 15° [triangle sum theorem]
b = 20 ft
c = ?
Using the law of sines, b/sin B = c/sin C, we have:
20/sin 15 = c/sin 33
(c)(sin 15) = (20)(sin 33)
c = (20 × sin 33)/sin 15
c ≈ 42.09
Use the sine ratio to find h:
∅ = 48°
Hypotenuse = c = 42.09
Opposite = h = ?
sin 48 = h/42.09
h = (sin 48)(42.09)
h ≈ 31.28
The correct measurements are:
B. m∠B = 15°
E. h ≈ 31.28 ft
