What is the solution to 2x-y=10 and y=-1/2x+5

(6, 2)

Step-by-step explanation:

Given the 2 equations

2x - y = 10 → (1)

y = x + 5 → (2)

Substitute y = - x + 5 into (1)

2x - (- x + 5) = 10

2x + x - 5 = 10

x - 5 = 10 ( add 5 to both sides )

x = 15

Multiply both sides by 2 and divide by 5

5x = 30 ⇒ x = 6

Substitute x = 6 into (1)

12 - y = 10 ( subtract 12 from both sides )

- y = - 2 ( multiply both sides by - 1 )

y = 2

Solution is (6, 2)

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 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
