Answer:

The value of a is -1.

Step-by-step explanation:

First, you have to add 3 to both sides :

2a - 3 + 3 =  - 5 + 3

2a =  - 2

Next, you have to divide both sides by 2 :

2a \div 2 =  - 2 \div 2

a =  - 1

3x+4y=5
2x+3y=

-2(3x+4y)=5(-2)
3(2x+3y)=4(3)

-6x-8y=(-10)
6x+9y=12

Add the equations

-6x-8y=(-10)
+ 6x+9y=12
-----------------
0x+y=2
y=2

Substitue y into an equation

6x+9(2)=12
6x+18=12
6x=-6
x = -1
y = 2

Is P 90 degrees from the origin, Q 180 degrees from the origin, and R 270 degrees from the origin?
krek1111 [17]

Answer:

Step-by-step explanation:

(x,y)→(-x,-y) (180° about the origin)

1.p(-3,2) ,in the second quadrant

P(-2,-3) is in 4th quadrant.

in the clockwise it is rotation of 270° about the origin.

2.

Q(-4,-5) is in 4th quadrant.

Q(4,5) is in 1st quadrant.

so it is 180° rotation in the clockwise direction.

3.

R(1,7) is in 1st quadrant.

R(7,-1) is in 4th quadrant.

Hence it is 90° rotation about the origin in clockwise direction.
