If we look at g (x), the line hits the y-axis at -0.5. This means your y-intercept is -0.5
Hope this helps!! :)
It's asking us to find the input value x such that f(x) = g(x). So let's look at the columns f(x) and g(x). We can see that both f(x) and g(x) have the value of 3. The x-value at which f(x) = g(x) = 3 is x = –1.
Thus the answer is x = –1.
Answer:
Step-by-step explanation:
All we are doing here is simply plugging in a 5 for x in the function and finding out the value.

so
1 pizza should cost $5.65
Pizza is $5.65 then bottle of coke is $2.45
3 pizzas and coke: ($5.65*3) + $2.45 = $19.4
I solved this by setting up and solving a system of linear equations:
Variables: p = pizza, c = coke
p = c+3.2
3p+c = 19.4
Solve by substitution
3(c+3.2) + c = 19.4
4c+9.6 = 19.4
c = 2.45
Re-plug in:
p = 2.45+3.2
p = 5.65
N>8 but with the little line underneath.
So choice two
