Answer:

Step-by-step explanation:

r/9 = -4

then multiply 9 to -4 which equals -36

at last, r is equal to -36

So you need to have the variables on one side and the constants on another.

Since r is divided by 9 on the left side, you have to get rid of the 9 by multiplying. r/9 times 9 equals r, and -4 times 9 equals -36.

So r = -36

Hope this helped!

The First two coefficients are positive because they are on the positive side of the y-axis.

The Last two are on the negative side of the y-axis. B is the closest to zero as the wider the graph is, the lower the coefficient is.

The coefficient with the greatest value would be D

____ [38]

Answer:

y = 5x+3

Step-by-step explanation:

a general line is represented by the equation:

y = mx + n

a line with m=5, that goes through (-1,-2), should satisfy the equation:

-2 = 5×(-1) + n

this is because any point on the line, satisfies it's equation.

from this we get n = 3, hence our answer

Solve the system using elimination. 3x + 3y = –9 3x – 3y = 21
scoundrel [369]

Answer:

y=-5,x=2

Step-by-step explanation:

3x+3y=-9________________eqn 1

3x-3y=21________________eqn 2

using elimination method

3x+3y=-9

-

3x-3y=21

subtract equation 2 from equation 1

0+6y=-30

6y=-30

y=-30/6

y=-5

substitute the value of y in equation 1

3x+3y=-9

3x+3(-5)=-9

3x-15=-9

3x=-9+15

3x=6

x=6/3

x=2
