I need help with easy math​

Mathematics
1 answer:
spin [16.1K]3 years ago
7 0

Answer: x = -1 and y = 9

The two equations are:

-9x + 2y = 23

-4x -y = -3

Now find for x in the first equation...

-9x + 2y = 23

-9x = 23 - 2y

x = (23 - 2y)/-9

Now place this value of x in the second equation and find for y...

-4{(23-2y)/-9} - y = -3

-92 + 8y + 9y = -3 * -9

17y = 27 + 92

y = 119/17

y = 7

Now place the value of y in the first equation," -9x + 2y = 23 " and find x

-9x + 2*7 = 23

-9x + 14 = 23

-9x = 23-14

x = 9/-9

x = -1

There you go! Hope it helps

Given that a function, h, has a domain of -3 ≤ x ≤ 11 and a range of 1 ≤ h(x) ≤ 25 and that h(8) = 19 and h(-2) = 2, select the
morpeh [17]

Answer:

Option D. h(2) = 16

Step-by-step explanation:

Verify each statement

case A) h(8) = 21

The statement is false

Because

we know that

h(8)=19 -----> given value

and

If h(8) = 21  then f(x) is not a function

case B) h(13) = 18

The statement is false

Because x=13 not belong to the domain of the function

case C) h(-3) = -1

The statement is false

Because

x=-3 belong to the domain

but

h(-3)=-1   not belong to the range of the function

case D) h(2) = 16

The statement could be true

Because

x=2 ----> belong to the domain of the function

h(2)=16 ----> belong to the range of the function
