if y varies directly as x and y is 48 when x is 48 when x is 6 which expression can be used to find the values of y when x is 2

Oksanka [162]

Answer:

the expression is

y=8x

Step-by-step explanation:

y varies directly as x is written as

$y \alpha x$

introducing constant

y=kx

from the question, when y=48, x=6

substitute it in the formula

48=6k

<em>maki</em><em>ng</em><em> </em><em>k</em><em> </em><em>the</em><em> subject</em><em> </em><em>by</em><em> </em><em>divi</em><em>ding</em><em> </em><em>throu</em><em>gh</em><em> </em><em>by</em><em> </em><em>6</em>

<em> $\frac{48}{6} = \frac{6k}{6}$ </em>

<em>k</em><em>=</em><em>8</em>

<em>put</em><em>ting</em><em> </em><em>the </em><em>va</em><em>lue</em><em> </em><em>of</em><em> </em><em>k</em><em> </em><em>in</em><em> </em><em>the</em><em> </em><em>exp</em><em>ression</em><em>,</em>

<em>y</em><em>=</em><em>8</em><em>x</em>

<em>the</em><em> </em><em>valu</em><em>e</em><em> </em><em>of</em><em> </em><em>y</em><em> </em><em>whe</em><em>n</em><em> </em><em>x</em><em>=</em><em>2</em>

<em>y</em><em>=</em><em>8</em><em>×</em><em>2</em>

<em>y</em><em>=</em><em>1</em><em>6</em>

<em>thu</em><em>s</em><em> </em><em>the </em><em>valu</em><em>e</em><em> </em><em>of</em><em> </em><em>y</em><em> </em><em>whe</em><em>n</em><em> </em><em>x</em><em>=</em><em>2</em><em> </em><em>is</em><em> </em><em>1</em><em>6</em><em>.</em>

p²>250250-44²

p²>248314

take the square root of both sides:

√p²>+√248314

p> 498.3 or 500 is the number

Please help me. I'm stupid.

Gwar [14]

Answer:

$\displaystyle 36\:units$

Step-by-step explanation:

Split up this Isosceles, Right Triangle into two congruent smaller right triangles. The reflexive side [the line that splits them apart] is 6 units, and both legs are 8 units, leaving the hypotenuses to AUTOMATICALLY be 10 units, according to the Pythagorean Theorem:

$\displaystyle a^2 + b^2 = c^2 \\ \\ 6^2 + 8^2 = 10^2 \\ \\ 36 + 64 = 100 \\ \\ 100 = 100$

With this Pythagorean Triple, we know that our dimensions are correct. Now, to find the perimeter, just add up all the sides EXCEPT for the divider:

$\displaystyle 2[10] + 2[8] = 20 + 16 = 36$
