How many solutions exist for the system of equations graphed below?
Zinaida [17]

Answer:

one

Step-by-step explanation:

When a system of equations is graphed, the solution is the coordinate that is plotted at the intersection of the two lines.

If the two lines cross once, there is only one solution.

If the two lines are on top of each other then there are infinitely many solutions.

If the two lines are parallel ( and never touch ) then there are no solutions

By looking at the graph we notice the two lines intersect once. So we can conclude that there is only one solution.

MAXImum [283]

Answer:The amount of commission made is 144

Step-by-step explanation:

The department store worker gets paid 325.00 per week plus 4% commission of their total sales. This means that the worker's earning is not fixed. It varies with the amount of sales made

if the worker sells 3600 of the merchandise, it means that the worker's sales commission will be 4% of 3600 of the merchandise

Sales commission earned by the store worker = 4/100 × 3600

= 0.04 × 3600 = 144

Find the area of the triangle with the given measurements. Round the solution to the nearest hundredth if necessary. B = 107°, a
Archy [21]

Answer:    105.19 \text{ square cm}      

Step-by-step explanation:

Since, by the SAS formula of finding the area of triangle,

The area of triangle, A = \frac{1}{2}\times s_1\times s_2\times sin\theta

Where, s_1 and  s_2 are adjacent sides and \theta  is the included angle of these sides

Here, s_1=22 s_2=10

And, \theta=107^{\circ}

Thus, the area of the triangle ABC,

A = \frac{1}{2}\times 22\times 10\times sin (107)^{\circ}

A = 110\times 0.95630475596

A = 105.193523156\approx 105.19\text { square cm}

Therefore, Third Option is correct.
