3x+2y=4
8x-3y=-6 solving systems of equations by substitution

x=0, y=2. (0, 2).

Step-by-step explanation:

3x+2y=4

8x-3y=-6

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

2(8x-3y)=2(-6)

9x+6y=12

16x-6y=-12

25x=0

x=0/25

x=0

3(0)+2y=4

0+2y=4

2y=4-0

2y=4

y=4/2

y=2

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh

its totaly b
