Please answer asap What is the value of x in the equation 3(2x + 4) = −6?

1 answer:

5 0

First divide 3 both side
Than move 4 to another side
Than divide by 2
$\frac{3(2x + 4)}{3} = \frac{ - 6}{3 } \\ 2x + 4 = - 2 \\ 2x = - 2 - 4 \\ 2x = - 6 \\ \frac{2x}{2} = \frac{ - 6}{2} \\ x = - 3$

Answer:

$(x-4)^2+(y+7)^2=43$

Step-by-step explanation:

The standard equation of a circle is given by:

$(x-h)^2+(y-k)^2=r^2$

Where (h, k) is the center and r is the radius.

We are given that the center is (4, -7) and that the radius is √(43).

So, h = 4, k = -7, and r = √(43). Substitute:

$(x-(4))^2+(y-(-7))^2=(\sqrt{43})^2$

Simplify. Hence, our equation is:

$(x-4)^2+(y+7)^2=43$

6. What is the equation in slope-intercept form of the line that passes

fomenos

Answer:

y=2x+5

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(9-(-1))/(2-(-3))

m=(9+1)/(2+3)

m=10/5

m=2

y-y1=m(x-x1)

y-(-1)=2(x-(-3))

y+1=2(x+3)

y=2x+6-1

y=2x+5
