G(x) is an absolute value function. The standard form for an absolute value function is f(x) = |x|.
The slope of this is equal to -6/-4 or 3/2.
It is flipped over the x-axis, so it will have a negative value out front.
g(x) = -3/2|x| is the equation for this graph.
Answer:
Step-by-step explanation:
First of all youre not going to get a direct answer to all of these questions, youre going to have 3 finally equations(because thats the amount of variables you have).
Answer:
The answer is the 2nd option
Step-by-step explanation:
First, you need to write to expressions to model each situation:
Plan A: 10+0.15x
Plan B: 30+0.1x
Next, set the expressions equal to each other and solve for x:
10+0.15x=30+0.1x
<em>*Subtract 0.1x from both sides to isolate the variable*</em>
10+0.05x=30
<em>*Subtract 10 from both sides*</em>
0.05x=20
<em>*Divide both sides by 0.05*</em>
x=400
The plans would have the same cost after 400 minutes of calls.
To find how much money the plans cost at 400 minutes, plug 400 into either expression. We'll use Plan A:
10+0.15(400)
10+60
70
The plans will cost $70.
Hope this helps!
