Equation would be y=5.43+.57m
let m stand for minutes
y= 5.43+.57×6
y=18.57
Answer: -2x+1
Step-by-step explanation:
Slope formula. -3-3/2- -1 = -6/3=-2=m
Y=mx+b use(-1,3) -1=x 3=y
3=-2(-1)+b
3=2+b
Subtract 2
1=b
Answer:
5.36
Step-by-step explanation:
Given that:
<BAD = <CAE, therefore, BD = EC
Let's take x to be the length of BD = EC
BD + DE + EC = BC
BC = 20,
BD = EC = x
DE ≈ 9.28
Thus,
x + 9.28 + x = 20
x + x + 9.28 = 20
2x + 9.28 = 20
Subtract 9.28 from both sides
2x + 9.28 - 9.28 = 20 - 9.28
2x = 10.72
Divided both sides by 2 to solve for x
BD ≈ 5.36
His average is 80%. You take the two scores add them up and divide by the number of scores.
