Answer:
Step-by-step explanation:
we have to just keep in mind to do the same operation to both sides of the equal sign
; subtract 7 from both sides
; multiply both sides by -1
; raise both sides to the power 3
2-x = (-5)³
2-x = -125 ; subtract 2 from both sides
-x = -125-2
-x =-127; multiply both sides by -1
x= 127

Option: C is the correct answer.
The equation of the Blue graph is:
C.
<h2>
Step-by-step explanation:</h2>
We are given a graph of a parent function F(x) as:
We know that the function G(x) is nothing but a translation transformation of the parent function by some units to the left.
Also we know that the transformation k units to the left or right is denoted by:
F(x) → F(x+k)
if k>0 then the shift is k units to the left.
and if k<0 then the shift is k units to the right.
Here we have k= 3 and shift is to the left.
Hence, the equation of translated function is:
G(x)=F(x+3)
i.e.

Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 given angles from 180 for B
B = 180° - (90 + 39)° = 180° - 129° = 51°
Using the tangent and sine ratios in the right triangle for b and c
tan39° = =
Multiply both sides by b
b × tan39° = 27 ( divide both sides by tan39° )
b = ≈ 7.5 ( to the nearest tenth )
sin39° = =
Multiply both sides by c
c × sin39° = 27 ( divide both sides by sin39° )
c = ≈ 28.0 ( to the nearest tenth )
