The solution to the simultaneous equation is x = 1 and y = 3

<h3>How to solve simultaneous equation?</h3>

1 / 3 x + y = 10 / 3

2x + 1 / 4 y = 11 / 4

multiply equation one by 3 and multiply equation 2 by 4

Therefore,

x + 3y = 10

8x + y  = 11

hence,

x + 3y = 10

24x + 3y = 33

23x = 23

x = 23 / 23

x = 1

Therefore,

1 + 3y = 10

3y = 10 - 1

3y = 9

y = 9 / 3

y = 3

Help please!
Alina [70]

Step-by-step explanation:

Given

f(x) = 8x - 9

Then

For a.

f(3y - 1 ) = 8(3y - 1 ) - 9

= 24y - 8 - 9

= 24y - 17

Now for b.

f(x) = - 23

or, 8x - 9 = - 23

8x = - 23 + 9

8x = - 14

x = - 14 / 8

x = - 7 / 4

Hope it will help :)

What is the domain of the function graphed below?​
vlabodo [156]

Answer:

x < 7

Step-by-step explanation:

the domain of a function defines the valid x values for the function.

as we go from left to right through all possible values of x, we see all values incl. x=-1 are creating a valid function result (y) for this function. until we reach x=7.

the empty ball indicates that there is no y value defined here. and for any value x>7 there is no y value defined.

so, x < 7 is the right one.
