Could use some help with this math problem. Solve: 4y + 3 = 15.

y = 3

Step-by-step explanation:

4y + 3 = 15  First subtract 3 from each side.

4y + 3 - 3 = 15 - 3   The 3 on the left will cancel.

4y = 15 - 3

4y = 12       Divide each side by 4

4y/4 = 12/4     The 4 on the left will cancel because 4/4 = 1

y = 12/4

y = 3

answer:

(-8,7)

explanation:

we know that  

f

(

−

3

)

=

7

therefore, if we wish to get the output as 7, in the function, we need to have our input to be -3.

looking at the function  

f

(

x

+

5

)

, what should the value of x be, such that the input in the function becomes 7?

we simply equate the terms,

x

+

5

=

−

3

x

=

−

8

thus, the point on the new function would be  

(

−

8

,

7

)
