Help need this answer as as possible
SashulF [63]

Answer:

15.5

Step-by-step explanation:

I can help with this. He doesn't tell how many dollars she earned from her dad but tells you what is left. So we add 13.73 + 1.77

We add because She used to spend it and because she only gave us what was left. We want to push it to what it was before so we do the opposite.

13.73 + 1.77 = 15.5

I am not really sure of what the words are on the last part but i think u can figure it out. My answer is 15.5 but if you aren't asking for this just ignore it.

Use the graph to find the solution of the system of equations {y = x^2 + 6x + 8 {y = x + 4
Phantasy [73]
Essentially when people ask you find the solution to system of equation, there asking at what x value do these to graphs intersect. The easiest way to do this is to get a graphing calculator, or desmos and type in the equation and find where they intersect. Heck, even the question says to solve it with a graph, but I'll demonstrate it algebraically.

One way you can do this is set the equation equal to each other. This is because you want to know at what x-value has the same y-value. So we get:

x^2 + 6x + 8 = x + 4

We can then combine like terms, or move everything to one side. So we get:

x^2 + 5x + 4 = 0.

Then we can use the quadratic formula to solve for x.

x=(-5 +/- sqrt(5^2 - 4(1)(4)))/(2(1)

This simplifies into:

(-5 +/- 3)/2

Finally we add and subtract:

(-5 + 3)/2 = x = -1
(-5 - 3)/2 = x = -4

And our solution is x = -1, x = -4
