Answer:
x= -19
Step-by-step explanation:
5x-10 = 7x +28
2x=-38
-38÷2
×= -19
Step-by-step explanation:
<u>Step 1: Factor the equation</u>

<u>Step 2: Find the x-intercepts of the graph of f(x)</u>
<u />

<u>Step 3: Describe the end behavior of the graph of f(x)</u>
Since the function is to the power of 2, that means that it is a parabola. And since the leading coefficient is negative, means that the arrows will be pointing down therefore, the end behavior of this graph is as x goes to infinity, f(x) goes to negative infinity and as x goes to negative infinity, f(x) goes to negative infinity.
<u>Step 4: What are the steps you would use to graph f(x)</u>
The first step that I would do is factor the equation. Then I would find the x-intercepts of the graph and plot them on the graph. I would then plug in 0 for all of the x values to get the y intercept. After doing that I would get the vertex using the vertex formula plotting it on the graph. Finally, I would connect all of the dots together to form the graph of the equation.
Answer:
$980
Step-by-step explanation:
1/5 of 2100 is 420, and 1/3 of 2100 is 700, so he spent $1120 in total. Subtract that from 2100, and you get $980 as your answer. Hope this helps!
