Find the value of x so that the function has the given value.
j(x)=−45x+7; j(x)=−5
Answer is 15
To find the value of x that makes the function j(x) equal to -5, we need to set up the equation:
-45x + 7 = -5
To isolate x, we will start by subtracting 7 from both sides:
-45x = -5 - 7
-45x = -12
Next, we'll divide both sides of the equation by -45 to solve for x:
x = (-12) / (-45)
Now we can simplify the fraction by canceling out the common factor of 3:
x = 4/15
Therefore, the value of x that makes the function j(x) equal to -5 is x = 4/15.
j(x)=−45x+7
; j(x)=−5
I would solve
−45x + 7 = −5 , expect to get a fraction
