Answer:
B) -x+8y=56
Step-by-step explanation:
y=1/8x+7
Multiply by 8 to clear the fraction
8y = 8(1/8x+7)
Distribute
8y = 8*1/8x +8*7
8y = x+56
Subtract x from each side
-x+8y = x-x+56
-x+8y = 56

C that is the answer hope I helped you guys
Answer: 90 degrees
============================
Explanation:
Let x and y be the two angles. Because they are supplementary angles, this means x+y = 180. Also since we're told that the angle is its own supplement, we can say that y = x.
Consequently, we can replace y with x and solve for x like so:
x+y = 180
x+x = 180 .... y is replaced with x since y = x
2x = 180
2x/2 = 180/2
x = 90
This means y = 90 as well. As a check, note how
x+y = 90+90 = 180
which verifies our answer.
To solve this using probability simply count the shapes that have at least 4 sides, and represent it as a fraction among all shapes in the spinner.
P(4 sides) = 5/6.
P(tails) = 1/2.
Both are independent events and as such must be multiplied with each other.
5/6 • 1/2 = 5/12,
This is the combined probability of both events occurring.
