Answer:

Fourth Quadrant

Step-by-step explanation:

a>0 = a is a positive number = +y

b<0 = b is a negative number = -x

[-b,-a] = [-(-x), -(+y)] = [x, -y]

[positive, negative] is on the fourth quadrant

What is the answer for -4x+4y=12 3x-4y=-18

Liula [17]

Use elimination.

-x = -6
X = 6

-4 (6) + 4y = 12
Y = 9

(X,y)

(6,9) is the solution

Olin [163]

184 = ¹/₂x(8.5 + 14.5)
184 = ¹/₂(23)
184 = 11¹/₂x
11¹/₂ 11¹/₂
16 = x

V2 - 15 = -2v Solve the Quadratic. What are the 2 solutions?

ki77a [65]

Answer:

v=-5 and v=3

Step-by-step explanation:

We are given that

$v^2-15=-2v$

We have to find two solutions of quadratic equation.

$v^2+2v-15=0$

Using addition property of equality

$v^2+5v-3v-15=0$ (By using factorization method)

$v(v+5)-3(v+5)=0$

$(v+5)(v-3)=0$

Substitute each factor equal to 0

$v+5=0$ and $v-3=0$

$v=-5$ and $v=3$

Hence, two solutions of quadratic equation are

v=-5 and v=3
