Answer: x= -2

               y=4

Step-by-step explanation:

-5x+3y=22   I

8x-2y=-24    II

-------------------------

From second equation exp. y and return it in to first equation

y=(24+8x)/2

y=12+4x

-5x+3(12+4x)=22

-5x+36+12x=22

7x=-14

x= -2

y=12+4*(-2)

y=12-8

y=4

quester [9]
If we have a common ratio every set amount of time (and not a common difference or addition), this is an exponential relationship. An exponential equation would have a form like Money = (1000)(2)^(# of months), where every additional month would cause the money amount to double.

Correct answer is C.

Both models have equal volume.

Model B has a larger surface area.

B_A\ \textgreater \ A_A
\\ A_V=B_V
\\
\\  \frac{B_A}{B_V} \ \textgreater \ \frac{A_A}{A_V}

2/3y + k = j. Solve for y
iVinArrow [24]

The value of y from the expression is y = 3/2(j-k)

<h3>Subject of formula</h3>

Given the expression below

2/3y + k = j.

Subtract k from both sides

2/3y = j - k

Divide both sides by 2/3

(2/3y)/2/3 =  (j-k)/(2/3)

y = 3/2(j-k)

Hence the value of y from the expression is y = 3/2(j-k)
