Solve the system of equations using the method of your choice

Mathematics
1 answer:
Vsevolod [243]2 years ago
5 0

Answer:

(-3, -1); x = -3; y = -1

Step-by-step explanation:

-3x + 5y = 4; x + y = -4

solving via substitution

rearrange second equation: y = -x - 4

-3x + 5(-x - 4) = 4

-3x - 5x - 20 = 4

-8x -20 = 4

-8x = 24

x = -3

- 3 + y = -4

y = -1

(-3, -1)

Check

- 3 + -1 = -4

A) To factor a quadratic equation, standard form is the better form to use because it is easier to pull out a common factor from. 

b) To graph a parabola, it is better to use vertex form so that you will know what point to graph as the vertex of the parabola. 

c) To identify the vertex, maximum and minimum, it is better to use vertex form because the vertex form will give the values of the coordinates for the vertex. Then, you can use the equation to find the mininmum or maximum. If the graph is negative, it will have a maximum because it points downward infinitely. If the equation is positive, the graph will have a minimum because the graph points upward infinitely.

d) Standard form is easier to use when trying to solve using the quadratic formula because  it is easier to see what the coeffiecnts and constants are to plug in for a b and c.

Pepsi [2]

Answer:

She sold 39 tall candies and 52 short candies

Step-by-step explanation:

x is all the tall candies

y is all the short candies

x+y=91

8x+5y=572

Use the method of Substitution to find out both x and y.

x=91-y

8(91-y)+5y=572

728-8y+5y=572

728-3y=572

3y=156

y=52

x+52=91

x=39
