Answer:
5(x + 3) = 3x - 4
=> (5 * x ) + (5 * 3) = 3x - 4
=> 5x + 15 = 3x - 4
=> 5x = 3x - 4 - 15
=> 5x - 3x = -4 - 15
=> 2x = -19
=> x = -19/2
=> x = -9.5

Answer:
y = 5/7 x -5
Step-by-step explanation:
X/7- y/5=1
Multiply each side by 35 to clear the fractions
35(X/7- y/5) =1*35
5x - 7y = 35
Subtract 5x from each side
5x-5x-7y = -5x+35
-7y = -5x+35
Divide each side by -7
-7y/-7 = -5x/-7 +35/-7
y = 5/7 x -5
Answer:
{12,15}
Step-by-step explanation:
Given the function f(x) = x+5, if the range of the function is {7,9}, the domain of the function is derived by simply finding the value of the function at each end point.
At endpoint x = 7,
f(7) = 7+5
f(7) = 12
At endpoint x = 9
f(9) = 9+5
f(9) = 14.
The function domain is therefore at {12,14}
