Answer: 24
Step-by-step explanation: thanks
Answer:
Construct MN.
Since M is the midpoint of OA, OM = MA
Similarly, N is the midpoint of OB.
Thus, ON = NB.
Now, in Δs OMN and OAB,
∠MON = ∠AOB (common angle)
(sides are in proportional ratio; OA = 2OM and OB = 2ON)
∴ Δs OMN and OAB are similar (2 sides are in proportion, with the included angle)
Since they are similar, then ∠OMN = ∠OAB (corresponding angles of similar triangles are equal)
But since ∠OMN = ∠OAB, then that means MN || AB (corresponding angles of two lines must be equal since they also sit relative to the transverse line, OA)
Thus, AB || MN (QED)
You'll have to adapt this problem statement to Brainly, as Brainly does not have the Segment Tool available.
"starts with 90 pencils" implies that the y-intercept is (0,90).
"gives away 15 pencils" implies a slope of -15 pencils per unit of time
Thus, the # of pencils Jabian still has is P(x) = 90 - (15 pencils / time unit)x
Answer: B
Step-by-step explanation: I took the quiz and got it right
Also, if you graph the equations on a graphing calculator, the lines are right on top of each other, so the first equation can't be less than -1, so no solutions
Add all the sides together or multiply two sides.
