Equation of a line: y=mx+b
m=slope(-1)
b=y-intercept(-7)
y=-1x-7 or y=-x-7
Answer:
107
Step-by-step explanation:
5x + 3 + 7x + 9 = 180
12x + 12 = 180
12x = 168
x = 14
7(14) + 9 = 107
Answer:
6.2832 square units (rounded off to four decimal values)
Step-by-step explanation:
Area of a semicircle = 
× π × r²
r (radius) = 2 units
For our semicircle the area = × π × 2² = 6.28318530718 square units
Or 6.2832 square units (rounded off to four decimal values)
Answer:
x = 11.25
Step-by-step explanation:
4x=45
divide 4 from both sides
4/4 x = 45/4
x= 11.25
Answer: 8.75
Step-by-step explanation:
