X— 3y+z= 6<br>2x — бу – 2 = -2<br>—x+y+ 2 = 7​
dlinn [17]

Answer:

x = -7 1/2

y = - 5/2

z = 11

Step-by-step explanation:

x— 3y+z= 6  (1)

2x — бу – 2 = -2  (2) <=> 2x - 6y = -2 + 2 = 0 <=> (2x - 6y)/2 = 0 <=> x - 3y = 0 (4)

—x+y+ 2 = 7​ (3) <=> -x + y = 7 - 2 <=> x - y = -5 (5)

Subtract (5) from (4), we have:

(x - 3y) - (x - y ) = 0 - (-5)

<=> x - 3y - x + y = 5

<=> -2y = 5

<=> y = - 5/2

Replace y with (4), we have x = 3 × (-5/2) = -15/2 (or -7 1/2)

Replace x with -15/2 and y with -5/2 in (1), we have z = 6 - (-15/2 - (-5/2)) = 6 + (15/2 - 5/2) = 6 + 5 = 11

[THESE ARE NOT THE RIGHT ANSWERS I JUST GUESSED]
marishachu [46]

The parent function of the function represented in the table is <u>exponential</u>.

  • Note if you subtract 10 from each output, you get f(x)=3^x.

If function f was translated down 4 units, the <u>f(x)</u> values would be <u>decreased by 4</u>.

  • See attached image.

A point on the table for the transformed function would be <u>(4, 87).</u>

  • f(4)-4=87
