531.72 is <span>9% of 5908.....</span>
Answer:
#1 d= 49t
Step-by-step explanation:
#2 Since the greatest value of n is 9, it means that the value of n is less than or equal to 9. But the values of n cannot be greater than 9. So, we will be using the sign of less than or equal to in the inequality. Thus, (D) is the correct option.
#3 is (29)
#4 is n=15
#5 is y = 7x
#6 is y=7x
X= width of the path.
we can suggest this equation:
(20+2x)(28+2x)=1584
we solve this equation:
(20+2x)(28+2x)=1584
560+40x+56x+4x²=1584
4x²+96x-1024=0
4/4x²+96/4x-1024/4=0/4
x²+24x-256=0
We solve this square equation:
x=[-24⁺₋√(576+1024)]/2=(-24⁺₋40)/2
we have two solutions:
x₁=(-24-40)/2=-32 this solution is not valid.
x₂=(-24+40)/2=8
Answer: the width of the path is 8 m.
Y = mx + b
m: slope
b: y -intercept
so the y intercept is -4 or (0,-4) as a coordinate
