Select all relations that represent a function. A {(-7,5),(3,-2), (-6,4),(-1,9),(-7,-3)}
B.{(6,-8), (-5, -8), (4,1),(-9,7),(-3,3)}
c. {(-2,6), (0,8), (-4,-5), (9,0), (7,2)}
D. {(9,9), (-8,1),(0,0),(-5, -6), (2,5)}

y=mx+b is the final answer!   : )

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4

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  

x

2  

x

​    

=240

=48
