Answer: B and C
Step-by-step explanation: For A, vertical angles can be complimentary or supplementary. For D, vertical angles can sometimes be acute but not always.
M(h)=5h
that is marcia's number of candles where she makes 5 candles per hour (h)
kevin makes 4 but already did 7 so
k(h)=4h+7
when will they have same numbre of candles?
when will m(h)=k(h)
set equal
5h=4h+7
minus 4h from both sides
1h=7
answer is 7 hours
system of equation is
m=5h
k=4h+7
find what value of h makes m=k true
answer is 7 hours
Answer: y > -1/2x + 2
Step-by-step explanation: first, in order to find the inequalities you should find the gradient by choosing two points from the line and you should you the formula m=y2-y1/x2-x1 to find the gradient.
Next, you should find the y-intercept in order to complete the inequality it can be easily found as the y-intercept is the place where the line crosses the y axis
Then you create your equation { y = -1/2x + 2 } and then if above the line is shaded then it is {> greater than} and if below the line is shaded then it should be {< less than}
(so you should replace the equation with the lesser or greater sign according to the way the graph is shaded)
