What is the solution to the system please help

Answer:

$(-\frac{50}{13},-\frac{12}{13})$

Step-by-step explanation:

To start, you need to find the equation of both of these lines. For the orange one, the slope can be found with the points (-5,0) and (0,-4), where there is a drop of 4 for a run of 5. This is a slope of -4/5, and a y-intercept of -4. For the purple line, you can use the points (-2,0) and (0,1), where there is a rise of 1 for a run of 2 or a slope of 1/2 and a y intercept of 1. Therefore, the two equations are:

$y=-\frac{4}{5}x-4$

$y=\frac{1}{2}x+1$

You can now set them equal to each other:

$-\frac{4}{5}x-4=\frac{1}{2}x+1$

Add 4 to both sides:

$-\frac{4}{5}x=\frac{1}{2}x+5$

Multiply both sides by 2:

$-\frac{8}{5}x=x+10$

Multiply both sides by 5:

$-8x=5x+50$

Subtract 5x from both sides:

$-13x=50$

Divide both sides by -13:

$x=-\frac{50}{13}$

$y=-\frac{12}{13}$

Hope this helps!

we know that

Fred bought
4 liters of liquid laundry detergent
3250 mL of fabric softener------------> 3250/1000-------> 3.25 liters
2.5 L of bleach-----------> 2.5 liters

then
statements

4a. Fred bought 75 milliliters more fabric softener than bleach
3.25-2.5-------> 0.75 liters--------> 750 mi
the statement is false

4b. Fred brought 1.75 liters more laundry detergent than bleach
4-2.5---------> 1.5 liters
the statement is false

4c. Fred brought 750 milliliters more fabric softener than bleach. 
3.25-2.5-------> 0.75 liters-------> 750 ml
the statement is true

4d. Fred brought 150 milliliters more laundry detergent than bleach.
4-2.5--------> 1.5 liters---------> 1500 ml
the statement is false

4e. Fred bought 0.75 liters more laundry detergent than fabric softener.

What is the equation of a parabola that opens left with a vertex of (-1,1)

xeze [42]

I think it is not possible to find a certain equation from just a given points, it must have more given information because there is a lot of parabola pass throw (-1,1).

You are paid $8.50/hr at your part-time job. Your deductions are FICA (7.65%), federal tax withholding (9.15%), and state tax wi

dexar [7]

$8.50/hr multiplied by 16 hours worked equals $136. $136 minus (7.65%)(136) equals $125.60. $125.60 minus (9.15%)(136) equals $113.16. Travel expenses of $6.00 multiplied by 4 equals $24. $113.16 minus 24 equals $89.16 net income.
