4x+3y=-2 find the value of y when x=1 asap

y = -2

Step-by-step explanation: You have to substitute 1 for x since x = 1/

SOOO...

4x + 3y = -2

4(1) + 3y = -2

4 + 3y = -2

-4          -4

3y = -6

3       3

y = -2

Hope this helps you :)

y = - 2

Step-by-step explanation:

4x + 3y = - 2

When x = 1

4(1) + 3y = - 2

4 + 3y= - 2

3y = - 2 - 4

3y = - 6

y = - 6/3

y = - 2

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places

answer: two angles are called supplementary if they add up to 180°. example: the two angles (140° and 40°) are supplementary because they add up to 180°.
