If x< -5 then x+5 < 0
but the absolute value of x+5 > 0
The answer is the last choice since in a function, x values in the coordinates cannot repeat themselves. In the first answer, the x-value 2 has more than one y-value meaning it cannot be a function. In the second answer, the x-value -2 also repeats itself and has more than one y-value, and in the 3rd choice, the x-value 5 also repeats.

Answer:
6a) x = -6
Let's solve your equation step-by-step.
14= 2x + 26
Step 1: Flip the equation.
2x + 26 = 14
Step 2: Subtract 26 from both sides.
2x + 26 − 26 = 14 − 26
2x = −12
Step 3: Divide both sides by 2.
2x/2 = −12/2
x=−6

7a) x = 4.25
Let's solve your equation step-by-step.
−30 =4 − 8x
Step 1: Simplify both sides of the equation.
−30 = 4 − 8x
−30 = 4 + −8x
−30 = −8x + 4
Step 2: Flip the equation.
−8x + 4 = −30
Step 3: Subtract 4 from both sides.
−8x + 4 − 4 = −30 − 4
−8x = −34
x=17/4 (Decimal: 4.25)
---------------------------------
8a) x = 8
Let's solve your equation step-by-step.
3(x − 4) = 12
Step 1: Simplify both sides of the equation.
3(x − 4) = 12
(3)(x) + (3)(−4)= 12(Distribute)
3x + −12 = 12
3x − 12= 12
Step 2: Add 12 to both sides.
3x − 12 +1 2 = 12 + 12
3x = 24
Step 3: Divide both sides by 3.
3x/3=24/3
x=8
Answer:
3v + 5u
Step-by-step explanation:
Write z = y^3 x^5 in terms of u and v.
Take the natural log (ln) of both sides. Then:
ln z = 3 ln y + 5 ln x
Substituting u for ln x and v for ln y, we get:
ln z = 3v + 5u (answer)
