Answer:

Step-by-step explanation:

The equation of quantities in direct variation is

y = kx ← k is the constant of variation

Given

7y = - x ( divide both sides by 7 )

y = - $\frac{1}{7}$ x ← in direct variation form

with k = - $\frac{1}{7}$

Sin(A) = opposite/hypotenuse = 12/13

Cos(A) = adjacent/hypotenuse = 5/13

Tan(A) = opposite/adjacent = 12/5

Is 2x+10 = -2(x-5) equals

faust18 [17]

First distribute -2 to both x and -5

-2(x) = -2x
-2(-5) = 10

2x + 10 = -2x + 10

False. 2x + 10 ≠ -2x + 10

False is your answer

hope this helps

The perimeter of GHJ

Dafna1 [17]

They have a scale factor of 5:6 so first we need to find the perimeter of KLM:
$11 + 14 + 17 = 42$
Then apply the scale factor of 5:6:
$\frac{5}{6} = \frac{x}{42}$
Set the denominators equal:
$\frac{35}{42} = \frac{x}{42}$
So we see that the perimeter of GHJ is 35.

Answer:

x^5y^5

Step-by-step explanation:

here's your solution

=> if base are same then power get added in multiplication

=> so, x^2 * y^4 * x^3 * y^1

=> x^2 * x^3 * y^4 * y^1

=> x^5*y^5
