If y varies directly as x, and y=6 as x=-1, find y for the x-value of 5

Tema [17]

Answer:

$y=-30$

Step-by-step explanation:

we are given

y varies directly as x

so, we can write equation as

$y=kx$

where

k is constant of proportionality

We have

at x=-1 , y=6

so, we can use it to find k

$6=k(-1)$

so, we get

$k=-6$

now, we can plug it back

$y=-6x$

now, we can plug x=5

and we get

$y=-6\times 5$

$y=-30$

Find the value of x in the triangle shown below.

nika2105 [10]

Answer:

$x = \sqrt{28}$

Step-by-step explanation:

Given,

Base of the triangle = 6

Hypotenuse of the triangle = 8

Let the height of the triangle = x

Therefore, According to Pythagoras Theorem,

${8}^{2} - {6}^{2} = {x}^{2}$

$= > 64 - 36 = {x}^{2}$

$= > 28 = {x}^{2}$

$= > x = \sqrt{28} (ans)$
