Whats the order pair of x,y for x-2y=-12 x 6y=20?

mote1985 [20]

X-2y=-12
x+6y=20
we can cancel x's
multiply first equation by -1 and add to 2nd equation

-x+2y=12
<u>x+6y=20 +</u>
0x+8y=32

8y=32
divide both sides by 8
y=4

sub back

x-2y=-12
x-2(4)=-12
x-8=-12
add 12 both sides
x=-4

(x,y)
(-4,4)

Identify the properties of the given quadratic.

Komok [63]

Answer:

see explanation

Step-by-step explanation:

A quadratic function in standard form is

y = ax² + bx + c (a ≠ 0 )

Given

y = - 3x² + 6x + 17 ← compare coefficients with standard form, then

a = - 3, b = 6, c = 17

Given the quadratic in standard form the the equation of the axis of symmetry is

x = - $\frac{b}{2a}$ = - $\frac{6}{-6}$ = 1

Equation of axis of symmetry is x = 1

10. rhombus abcd has vertices at a(-2, 7), b(8, 7), c(2, -1), and d (-8, -1).

horrorfan [7]

Answer: 80

Step-by-step explanation:

We can use the formula $A=\frac{d_{1}d_{2}}{2}$ , where $d_{1}, d_{2}$ are the lengths of the diagonals.

By the distance formula,

$AC=\sqrt{(-2-2)^{2}+(-1-7)^{2}}=\sqrt{16+64}=4\sqrt{5}\\BD=\sqrt{(-8-8)^{2}+(-1-7)^{2}}=\sqrt{256+64}=8\sqrt{5}$

So, the area is $\frac{(4\sqrt{5})(8\sqrt{5})}{2}=\boxed{80}$
