Answer:

7 hours

Step-by-step explanation:

15/2 hours=7 1/2 hours

(15÷2=7 1/2)

8 1/2 hours - 7 1/2 hours = 1 hour

(find the difference)

1 week = 7 days

1 hour × 7 days = 7 hours

(1 hour difference for one day, multiply 7 for a week)

Write the points (-3,5) and (1,1) in slope-intercept form

Jobisdone [24]

Y=mx+b
m=slope
b=yint

find slope
slope between (x1,y1) and (x2,y2) is (y1-y2)/(x1-x2)

given
(-3,5) and (1,1)
slope=(5-1)/(-3-1)=4/-4=-1

y=-1x+b
find b
when x=1, then y=1
1=-1(1)+b
1=-1+b
add 1
2=b

y=-x+2

1: Is 5 / 3(1-x) Equivalent to 8-8x<br><br> 2: Is 2(6 - 3x) equivalent to 2(3x) +x?

Answer:

1. no. 2.no

Step-by-step explanation:

1. $\frac{5}{3 - 3x}$

= (5\3) × (1/1-x)

but 8-8x = 8(1-x)

2. 2(6-3x) = 12-6x =6(2-x)

2(3x) + x= 6x +x = 7x
