Answer:
After 5 hours the two would charge the same amount of money.
Step-by-step explanation:
Designer A: $450 + ($105/hr)x, where x is the number of hours worked;
Designer B: $725 + ($50/hr)x
Equating these two formulas, we get:
$450 + ($105/hr)x = $725 + ($50/hr)x
Subtracting $450 from both sides: ($55/hr)x = $275
Dividing both sides by $55 yields the number of hours worked:
x = $275/$55 = 5
After 5 hours the two would charge the same amount of money.
So, we have the points. Here are the graphs:
So, the answer is d

Answer:
a. One solution
Step-by-step explanation:
These are two linear equations with different x-coefficients. They have one solution.

<em>Additional comment</em>
If the x-coefficients are the same, the system may have 0 or infinite solutions, depending on the constants. It is not possible for a system of linear equations to have exactly two solutions.
The number sentence would be 8+9=17 because commutative property is when you just switch around the numbers but get the same answer.
