Question

Определите. при каком значении аргумента функция Y=7X-6 ПРИНИМАЕТ ЗНАЧЕНИЕ . РАВНОЕ -20 .

Answer 1

Y=-20
-20=7x-6
-7x=-6+20
-7x=14:(-7)
x=-2

Answer 2

Y = 7x - 6
Y = - 20
7x - 6 = - 20
7x = - 14
X = - 2

Answer 3

Determining the Value of X for Y=7X-6

To determine the value of X for which the function Y=7X-6 takes the value equal to -20, we can set up the equation and solve for X.

Y=7X-6

We want to find the value of X when Y is equal to -20.

-20=7X-6

Now, let's solve for X:

7X-6=-20

7X=-20+6

7X=-14

X=-14/7

X=-2

So, the function Y=7X-6 takes the value equal to -20 when X is equal to -2.
