Well I don't know !
Let's get together and solve that thing for 'y' .
2x + 3y = 1,470
Subtract 2x from each side: 3y = -2 x + 1,470
Divide each side by 3 : y = -2/3 x + 490
There you are.
If you graph that equation, the slope is -2/3
and the y-intercept is 490 .
Answer:
104×104=10816
Step-by-step explanation:
104²=104×104
=10816
You said that (xy) = 16, and (x+y) = 4 .
From the second equation you can get [ x = 4 - y ],
then substitude that for 'x' in the first equation, and
finally, rearrange the first equation to read
<u>x² - 4x + 16 = 0</u>
Don't even try to factor that quadratic equation. Go straight
to the quadratic formula, and the two solutions you find are ...
<em>x = 2 + i 2√3</em>
and
<em>x = 2 - i 2√3</em> .
Those are the two number that do what you want.
There are no <u>real</u> numbers that can do it.
Answer:
5/3
Step-by-step explanation:
3^5 = 27 ^x
Rewrite 27 and 3^3
3^5 = 3^3^x
We know that a^b^c = a^(b*c)
3^5 = 3^(3x)
The bases are the same so the exponents are the same
5 = 3x
Divide by 3
5/3 =x
