Answer:
slope is m
y = mx + b is your standard formula
slope = -3
Step-by-step explanation:
Answer:f(x)=4x+1=9
=> 4x=9-1
=> 4x=8
=>x=2
Step-by-step explanation:
check the picture below.
so the playground is really just 3 rectangles and one triangle, now the triangle has a base of 8 and a height of 6. We can simply get the area of each figure, sum them up and that's the area of the playground.
Give better description if they are both identical
Since all triangle's angle's values add up 180 degrees, this means we have to make sure to angles add up to 180.
A. 75 + 35 = 110. 180 - 110 = 70 degrees.
B. This triangle is isosceles meaning 2 of its sides is the same length. In this case, the two sides add up to 140 (meaning they are both 70 degrees). 180 - 140 = 40 degrees.
C. I sadly don't know how to solve it.
D. This is another isosceles triangle. 180 - 36 = 144.
