6. Solve the system of equations by graphing. 17.
y = -x + 7
5x + 5y = 10

∅

Step-by-step explanation:

Firstly, you need to draw the line of equation: x - 5y =1

and the line of equation: 2x + 5y = 17

and observe their intersection

it would be : a line , nothing or a point

By looking at the photo below you might notice that the two lines are parallel then they don’t intersect there the solutions set is ∅ (empty set)

i agree because i see the other persons thinking is clear

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
