Answer:

<h2>see the answers ⤵️</h2>

Step-by-step explanation:

<h3>to understand the solving steps</h3><h3>you need to know about</h3>
  • \sqrt{ \frac{x}{y} }  <  =  >  \frac{ \sqrt{x} }{ \sqrt{y} }  \\ and \:  \\  \sqrt{x}  \times  \sqrt{y}  =  \sqrt{xy}
  • PEMDAS

let's solve:

a) \sqrt{ \frac{9}{25} }

\frac{ \sqrt{9} }{ \sqrt{25} }

\frac{3}{5}

b) \frac{ \sqrt{12} }{ \sqrt{3} }

\frac{ \sqrt{12} }{ \sqrt{3} }  \times  \frac{ \sqrt{3} }{ \sqrt{3} }

\frac{ \sqrt{12 \times 3} }{ (\sqrt{3} )^{2} }

\frac{ \sqrt{36} }{3}

\frac{6}{3}

2

c) \frac{ \sqrt{15} }{ \sqrt{3} }

\sqrt{5}

ILL GIVE U STUFFFFF PLZZZZZZZZZZZ ANSWER ITTTTTTTTT
belka [17]

Answer:

Slope: -\frac{3}{4}

Y-intercept: 399

Slope-intercept form: y=-\frac{3}{4}x+399

Step-by-step explanation:

1. The equation in Standard form is given in the problem:

3y+4y=1596

2. Then, to write the equation of the line in slope-intercept form  y=mx+b, where <em>m</em> is the slope and <em>b</em> is the y-intercept, you must solve for <em>y</em> as you can see below:

4y=-3x+1596\\y=\frac{-3x+1596}{4}\\y=-\frac{3}{4}x+399

3. Therefore, the slope and the y-intercept are:

m=-\frac{3}{4}\\b=399

Jeanine is twice as old as her brother Marc. If the sum of their ages is 24. How old is Jeanine?
Tanya [424]
Let Marc's age be x. If Jeanine is twice as old as Marc, then her age will be 2x. If their ages added together are 24, then you can create the following equation:

2x + x = 24
3x = 24
x = 8

Remember that x is Marc's age. So if Marc is 8, and Jeanine is twice as old, she will be 16.
