x = 8

Explanation:

AE = 3x - 4

EC = x + 12

SInce diagonals AC and DB intersect at E

it means the lines which meet at the intersection E are equal. A and C meet at E which gives AE and EC

AE = EC

3x - 4 = x + 12

collect like terms:

3x - x = 12 + 4

2x = 16

divide both sides by 2:

2x/2 = 16/2

x = 8

Let's solve :

a.) The equation will be :

  • xy =  - 3

  • y =  \dfrac{ - 3}{x}

b.) the table will be like this :

  • for x = 1 , y = -3

point (1 , -3)

  • for x = 3 , y = -1

point (3, -1)

  • for x = -1 , y = 3

point (-1 , 3)

  • for x = -3 , y = 1

point (-3 , 1)

c.) graph the equation as shown in attachment !

Can someone please be nice enough and give me all the answer for these questions.

1. 1/9 since you take all the "a"s in the words which is 2/18
2.2/9 same thing as above
3.18/18 since there is no "O" it's a trick question
4.3/9
5.5/6 since you don't count 6
6.1/2 and 1/2 coins are always 1/2 unless you flip twice
7.5/13
8.1/2 because 1,3,5 odd 2,4,6 even 
Hope that helps

In each of the following equations, what is y when z=2? When x = 0? Where would the graph of each equation cross the y-axis? Hom
Lelechka [254]

Answer:

a. y = 3 × 0 + 15

y= 0+15

y= 15

Step-by-step explanation:

Subtitute the variables into the place they are denoted with and solve it

And the place where the equation will cross the y axis is just the last numbers i.e. 15 and 3z which is 6
