Which equations have one solution

  C and  F

Step-by-step explanation:

Remember that for two equations to have the same solutions they need to have the different slopes and different y intercepts or they could have the same y-intercepts but different slopes.

First we will simply each of the equations  

A.     reduces to .   Since this have the same slopes and same y-intercept they have infinitely many solutions

B. x +3 + 3x = -3 +4x +6  reduces to 4x + 3 = 4x +3  This also have the same slopes and same y-intercepts which means it also have infinitely many solutions.

C. 2(1/5 + 1/4x) -2x = x -1  reduces to  -3/2x +2/5 = x -1   This have different slopes and different y intercepts so they have One solution.

D . 4.3x + 2.5 -2.2x + 2.2 -2.1x = 0   reduces to  4.7 = 0  which means that this equation have no solution because 4.7 does not equal 0.  

E. 2(4x +3) + 2x= 5(2x + 3)    reduces to  10x + 6 = 10x + 15   which means this also have No solution because they have the same slopes but different  y-intercepts.

F.  2/5x + 10 + 3/5x = 2x + 5 reduces to 1x + 10 = 2x + 5   This also have 1 solution because they have different slopes and different y intercepts.

it would more likely be bald eagle because its has more in the box so about 75%.

step-by-step explanation:

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2
