Y = 7x + 9<br> 2y + 2x = -18
zvonat [6]

Answer:

Step-by-step explanation:

Just multiply the first equation by -1 and then add them together to find x. Should look something like

-2x - y = -7

5x + y = 9

--------------------

3x + 0 = 2

x = 2/3

Now back substitute using either equation to find y. I'll use the first:

2(2/3) + y = 7

4/3 + y = 7

y = 7 - 4/3 = 21/3 - 4/3 = 17/3

Answer:

x=2/3

y=17/3

Twenty five X squared minus one hundred and forty four
neonofarm [45]

OK.

-- Since it's the difference of two squares,
the factored form of that expression is

                 (5x + 12) (5x - 12) .

-- We don't know the value of the expression
until you tell us the value of 'x'.  And then, if
'x' changes, the value of the expression also
changes, immediately, without any delay.
Faster than the speed of light.

F(x)=2x+7
konstantin123 [22]
F(x) = 2x + 7
g(x) = 3x² - 1

f(g(x)) = 2(3x² - 1) + 7
f(g(x)) = 2(3x²) - 2(1) + 7
f(g(x)) = 6x² - 2 + 7
f(g(x)) = 6x² + 5

The answer is A.
