x= -2, y= -7

Step-by-step explanation:

(Solve for y)

-3x+y=-1

1. add 3x to both sides

y=3x-1

(Substitute y=3x-1 into 2x-3y=17)

1. 2x-3(3x-1)=17

2.Simply it (Distributive Property)

3. -7x+3=13

(Solve for x)

1. Subtract 3 from both sides

2.  Divide both sides by -7

3. x=-2

(Substitute x=-2 into y=3x-1)

1.  y= 3 x -2-1

2. y= -7

Therefore ,

x= -2

and

y= -7

d (5 x (-20)) * (100 x (0.7))

step-by-step explanation:

5÷1/100 * -.7 *-20

copy dot flip

5*100 * -.7 *-20

rearrange

5*-20   * 100 *-.7

-100   *-70

7000

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
