question 1 = -0.5
question 2 = 6 - 3y
question 3 = 3x + 6
question 1
to evaluate (x + 1)/3 when x = -2.5, plug the value of x into the equation
(x + 1)/3
= (-2.5 + 1)/3
= (-1.5)/3
= -0.5
question 2
to solve this, distribute the 1/2 through the parentheses
(1/2) * (4 − 6y + 8)
= (1/2 * 4) + (1/2 * -6y) + (1/2 * 8)
= 2 + (-3y) + 4
= 6 - 3y
question 3
to solve this, distribute the 3 through the parentheses
3(x + 2)
= (3 * x) + (3 * 2)
= 3x + 6
<em>note - i tried to plug -2.5 into x + (1/3) for question 1, but the answer wasn't among the solutions, so i assumed the equation was (x+1)/3 instead since its answer was among the solutions</em>
Answer:
use inverse operations (answer choice b)
Step-by-step explanation:
the use of inverse operations allow for things to cancel out so that you can be left with the variable and a single value

Answer:
ABOVE the x-axis
Step-by-step explanation:
Please use "^" to denote exponentiation: y = x^2 + 2x + 3
To find the vertex, we must complete the square of y = x^2 + 2x + 3, so that we have an equivalent equation in the form f(x) = (x - h)^2 + k.
Starting with y = x^2 + 2x + 3,
we identify the coefficient of x (which is 2), take half of that (which gives
us 1), add 1 and then subtract 1, between "2x" and "3":
y = x^2 + 2x + 1 - 1 + 3
Now rewrite x^2 + 2x + 1 as (x + 1)^2:
y = (x + 1)^2 - 1 + 3, or y = (x + 1)^2 + 2. Comparing this to f(x) = (x - h)^2 + k, we see that h = 1 and k = 2. This tells us that the vertex of this parabola is at (h, k): (1, 2), which is ABOVE the x-axis.
