add the like terms that are on the left, then isolate the variable (a) on the left by dividing both sides by .

2a + 6a = -24

8a = -24 <em>added like terms (2a + 6a)</em>

8a/8 = -24/8 <em>divided both sides by 8</em>

a = -3 <em>simplified (8/8 = 1 and -24/8 = -3)</em>

Answer: -3

Answer:

h(g(x)) = (1/5)x² +4/5

Step-by-step explanation:

$(h\circ g)(x)=h(g(x))=h(x^2+2) = \dfrac{(x^2+2)+2}{5}=\dfrac{x^2+4}{5}\\\\\boxed{(h\circ g)(x)=\dfrac{1}{5}x^2+\dfrac{4}{5}}$

Domain and range of graph need ASAP

Lostsunrise [7]

Answer:

Domain: $-6 \leq x \leq 3$

Range: $-3 \leq x \leq 6$

Step-by-step explanation:

The domain is the set of real values which can be inputted into a function and produce a real output. In this case, the domain is the following: $-6 \leq x \leq 3$ , because this is the set of real values for which the function will produce a real output.

The range is the set of real values which a function outputs when a value from the domain is entered into the function. This is the set of y-values that one can see on the graph, the possible y-values are in between (-3) and (6).
