7/1000 and 427/1000
divide 42 by 7/1000
you get 6,000

I really need help with this since I have a math test tomorrow, I'd really appreciate it if someone could help.

Ok first of all, I EXTREMELY appreciate your use of parenthesis. Ok so first just raise both sides to the power of 1/2.

$(\frac{3}{8})^{x}=\frac{8}{11}$

You'll see why I didn't include a negative. Then apply the log base 3/8 and you get

$x = log_{ \frac{3}{8} }( \frac{8}{11} )$
Then you split the log up and you get
$x = log_{ \frac{3}{8} }(8) - log_{ \frac{3}{8} }(11)$
You couldn't put a negative value for a log. That is why I excluded the negative part of the sqrt.

What are the solutions to the following system of equations? y = x2 + 3x − 7 3x − y = −2 (2 points) (3, 11) and (−3, −7) (11, 3)

Minchanka [31]

ANSWER

(3, 11) and (−3, −7)

EXPLANATION

The given system of equations are:

$y = {x}^{2} + 3x - 7$

and

$3x - y = - 2$

or

$y = 3x + 2$

We equate the two equations to obtain,

${x}^{2} + 3x - 7 = 3x + 2$

We rewrite in standard quadratic form to obtain,

${x}^{2} + 3x - 3x - 7 - 2 = 0$

This simplifies to

${x}^{2}- 9= 0$

We solve for x to obtain,

${x}^{2} = 9$

$x = \pm \sqrt{9}$

$x = \pm 3$

$x = 3 \: or \: x = - 3$

When
$x = 3$

$y = 3(3) + 2 = 11$

When x=-3,

$y = 3( - 3) + 2 = - 7$

Therefore the solution for the system is (3, 11) and (−3, −7).
