Answer:

-2

Step-by-step explanation:

First, let's put this in slope-intercept form:

-5y-3x=10

5y = -3x - 10

y = (-3/5)x - 2

The y-intercept is -2.

the length of a rectangle is 4in more than its width, and its perimeter is 34in find the length and width of the rectangle

Anna [14]

Let $l$ and $w$ be, respectively, the length and the width of the rectangle.

If the length is 4 inches more than the width, we have

$l = w+4$

Moreover, the perimeter of a rectangle is given by

$2(l+w)$

And we can substitute $l=w+4$ to get

$2(w+4+w)=2(2w+4)=4w+8$

We know that the perimeter is 34 inches:

$4w+8=34 \iff 4w = 26 \iff w = \dfrac{26}{4}=6.5$

Which implies

$l=w+4=6.5+4=10.5$

Find value of P and Q

ch4aika [34]

Answer:

$P= 6 \frac{1}{7}\\\\Q = 4 \frac{2}{7}$

Step-by-step Explanation

$\frac{5 + 3 \sqrt{2} }{5 - 3 \sqrt{2} } = P+Q\sqrt 2 \\ \\ \frac{(5 + 3 \sqrt{2}) }{(5 - 3 \sqrt{2}) } \times \frac{(5 + 3 \sqrt{2}) }{(5 + 3 \sqrt{2} )} = P+Q\sqrt 2 \\ \\ \frac{ {(5 + 3 \sqrt{2} )}^{2} }{ {(5)}^{2} - (3 \sqrt{2})^{2} } = P+Q\sqrt 2 \\ \\ \frac{ {5}^{2} + {(3 \sqrt{2} )^{2} + 2.5.3 \sqrt{2} } }{25 - 9 \times 2} = P+Q\sqrt 2 \\ \\\frac{ 25 + 18 + 30 \sqrt{2} }{25 - 18} = P+Q\sqrt 2 \\ \\\frac{ 43 + 30 \sqrt{2} }{7} = P+Q\sqrt 2 \\ \\ \frac{43}{7} + \frac{30 }{7} \sqrt{2} = P+Q\sqrt 2 \\ \\ equating \: like \: terms \: on \: both \: sides \\ \\ P = \frac{43}{7} \\ \\ \huge \red { \boxed{ P= 6 \frac{1}{7}}} \\ \\ Q = \frac{30}{7} \\ \\ \huge \orange { \boxed{ Q = 4 \frac{2}{7} }}$
