Answer:

±2  sqrt(3) = x

Step-by-step explanation:

12 -x^2 =0

Add x^2 to each side

12 -x^2+x^2 =0+x^2

12 = x^2

Take the square root of each side

±sqrt(12) = sqrt(x^2)

We know that sqrt(ab) = sqrt(a) sqrt(b)

±sqrt(4*3) = sqrt(x^2)

±sqrt(4) * sqrt(3) = x

±2  sqrt(3) = x

Through the point (3,1.2) that has an y intercept of 3
topjm [15]

Answer:

y = -0.6x +3

Step-by-step explanation:

equation of the line through point (3, 1.2) and y-interecept of 3

y= mx+b

m is the slope and b is thhe y-intercept

y = mx + 3

between points (3, 1.2) and (0,3) the slope is

m= (y2-y1)/ (x2-x1) = (1.2-3) / (3-0) = -1.8/3 = -0.6

y = -0.6x +3

Help help help<br><br> solve for x<br> 2x + 3 /12 = 2x/8
pickupchik [31]
2x + 3 /12 = 2x/8
⇒ 48x/24 + 6/24 = 6x/24
⇒ (48x+ 6)/24= 6x/24
⇒ 48x+ 6 = 6x
⇒ 48x- 6x= -6
⇒ 42x= -6
⇒ x= -6/42
⇒ x= -1/7
