Answer:
14400
Step-by-step explanation:
X - X × 75%=3600
X - X ×
= 3600
X -
= 3600
= 3600
= 3600
X = 3600 × 4
X = 14400

Answer:
The first and last graph.
General Formulas and Concepts:
<u>Algebra I</u>
- Solving systems of equations graphically
Step-by-step explanation:
In order for a systems of equations to have a solution set, the 2 graphs must intersect at at least 1 point. Here, we see that graphs 1 and 5 do not intersect each other at all.
Therefore, the rest of the graphs have solutions and #1 and #5 do no have any solutions.
Answer:

Step-by-step explanation:
we have the expression

Convert to vertex form

where
a is the leading coefficient
(h,k) is the vertex
Complete the square


Rewrite as perfect squares

so
The coefficient a =1
The vertex is the point (-2,-2)
