How do I find the values of these

skad [1K]

Since the triangles are similar, then 32 = x+7 those two angles are too
solve for "x"

now using proportions $\bf \cfrac{\textit{small triangle}}{\textit{large triangle}}\qquad \cfrac{JK}{18}=\cfrac{12}{12+10}$

solve for JK

$\bf \cfrac{\textit{small triangle}}{\textit{large triangle}}\qquad \cfrac{12}{12+10}=\cfrac{9}{9+KG}\implies 12(9+KG)=(22)9
\\\\\\
108+9KG=198$

solve for KG

the scale factor of the perimeter of both triangles is just the same as the ratio of the sides, or $\bf \cfrac{12}{12+10}$

-2x < -6

Soloha48 [4]

Answer:

x > 3

Step-by-step explanation:

This is based on the concept 'when a negative number is multiplied to both sides of the inequality, the sign gets reversed. For example, x > - 2 when it is multiplied by - 1, it becomes - x < 2.'

*only when the number is -ve.

Similarly, in this question, multiply both sides by - 1.

2x > 6

x > 6/2

x > 3

For more : take - 5 > - 2, as you know

Note that 5 is actually greater than 2. To make this true we change signs

20. WILL MARK BRAINLIEST!! HELP!

aleksklad [387]

Answer:

the function has vertical asymptotes at x= 4 and x= -2

this is where the bottom of the function equals zero and the function is undefined at these points

so the correct answer is c

T varies inversely with the cube of W. When W is 3, T is 1/9. Find the value of W when T is 1/243

Lera25 [3.4K]

T varies inversely with the cube of W

$T = k/W^3$

$\frac{1}{9} = k/3^3$

$k = \dfrac{3^3}{9} = 3$

$W^3 = k/T$

$W = \sqrt[3]{ k/T }$

When $T=1/243$

$W = \sqrt[3]{ 3/(1/243)}= \sqrt[3]{729} = 9$
