brilliants [131]2 years ago
4 0

Answer:

x^2 – 4 = 0

Step-by-step explanation:

When x = - 2,

x^2 - 4 = 0

( - 2 )^2 - 4 = 0

4 - 4 = 0

When x = 2,

x^2 - 4 = 0

2^2 - 4 = 0

4 - 4 = 0

Which quantity is proportional to 12⁄48?
Finger [1]

Answer:

we know that

16/4-----------> 8/2---------> 4/1

so

case 1) 

64/16--------> 32/8-----> 16/4------> 8/2------> 4/1

the quantity (64/16) is proportional to 16/4

case 2)

6/1 is not 4/1

so

the quantity (6/1) is not proportional to 16/4

case 3)

5/1 is not 4/1

so

the quantity (5/1) is not proportional to 16/4

case 4)

48*12--------> 24/6-----> 12/3------> 4/1

the quantity (48/12) is proportional to 16/4

case 5)

4/1 is equal to 4/1

so

the quantity (4/1) is proportional to 16/4

Write an equation in point slope form that passes through (-14, - 6) and the<br> slope is 2/3
s344n2d4d5 [400]

Answer:

y=2/3x - 6

Step-by-step explanation:

use the formula y=mx+b. the m of this equation is equal to the slope and you know that the slope is 2/3. the b of the equation is equal to the y-intercept so, to find b you simply look at the points given. the points are written in (x,y) form so if -14 is x, -6 must be y. remember to KEEP CHANGE CHANGE your signs so that plus sign becomes negative 6. Hope this helps!
