X + 3y = −4 x + 5y = −6

lesya [120]3 years ago

For this case we must solve the following system of equations:

x + 3y = -4\\x + 5y = -6

We clear x of both equations:

x = -4-3y\\x = -6-5y

We match:

-4-3y = -6-5y\\-3y + 5y = -6 + 4\\2y = -2\\y = \frac {-2} {2}\\y = -1

We find the value of "x":

x = -4-3 (-1)\\x = -4 + 3\\x = -1

Thus, the solution of the system is:

(x, y): (- 1, -1)

Answer:

(x, y): (- 1, -1)

what is the value of the discriminant, b2 − 4ac, for the quadratic equation 0 = −2x2 − 3x 8, and what does it mean about the num
Naily [24]
Rewrite the equation:

-2x^2 - 3x + 8 = 0

2x^2 + 3x -8 =0

Where a=2, b=3 and c=-8

Then b^2 - 4ac = 3^2 - 4(2)(-8) = 9 + 64 = 73

A positive discriminant implies that the equation has two different real solutions.

Answer:  the discriminant is 73, so the equation has 2 real solution

The first side of a triangle is 2 inches shorter than three times the second side. The third side is 1 inch longer than twice th
statuscvo [17]

Answer:

The perimeter of a triangle is 74 inches. The second side is 2 inches more than twice the first side, and the third side is 6 inches less than three times the first side. Find the lengths of the three sides of the triangle.

Length of Sides (in inches)

Let's call the first side x.

Then, the problem says:

The second side is 2 inches more than twice the first side:

Second side = 2x+2

and the third side is 6 inches less than three times the first side:

Third side = 3x-6

The perimeter is the sum of the lengths of all sides, so in this case we get:

x+2x+2+3x-6 = 74 Add all x on left and also add 2 and -6:

6x-4 = 74 Add 4 on both sides

6x = 78 Divide both sides by 4:

x = 13 is the first side

Second side 2(13)+2

Third side 3(13)-6
