Question

При каком значении аргумента значение функции у=2.5х+2 равно 7?

Answer 1

у=7

2,5х+2=7

2,5х=5

х=2

при 2

Answer 2

To find the value of the argument (x) when the function y = 2.5x + 2 is equal to 7, you can set the equation equal to 7 and solve for x.

Given: y = 2.5x + 2

We want y to be equal to 7, so we have:

7 = 2.5x + 2

Now, we need to isolate x on one side of the equation:

Subtract 2 from both sides:

7 - 2 = 2.5x

5 = 2.5x

Now, divide both sides by 2.5 to solve for x:

x = 5 / 2.5

x = 2

So, when x is equal to 2, the value of the function y = 2.5x + 2 is 7.
