We can use substitution method to solve for this system of equations. We calculate as follows:

<span>2x – 6y = –14
-6y = -14 -2x
y = x/3 + 7/3

 </span>5x – 3y = –11
 5x – 3(x/3 + 7/3) = –11
5x - x + 7 = -11
4x = -11 -7
4x = -18
x = -9/2
y = -9/2(3) + 7/3
y = 5/6

Lubov Fominskaja [6]

Answer:  A= s^2 <- for a square

A= 1/2*b*h <- for a triangle

A= 4^2= 16

A= 1/2*8*6 (The whole height is 8 yd)

A= 1/2*48

A= 24

24+16= 40 yd^2

"B" is the answer.

I hope this helps!

Please help in the question it should be if t=-6 when r =-2 its an error
Natasha2012 [34]

Answer:

r = - \frac{12}{7}

Step-by-step explanation:

Given that r varies inversely as t , then the equation relating them is

r = \frac{k}{t} ← k is the constant of variation

To find k use the condition t = - 6 when r = - 2, then

- 2 = \frac{k}{-6} ( multiply both sides by - 6 )

12 = k, thus

r = \frac{12}{t} ← equation of variation

when t = - 7, then

r = \frac{12}{-7} = - \frac{12}{7}
