Joel has a goal to practice his clarinet for 4 hours per week. The list 5 1below shows the number of hours Joel has practiced so far this week. Monday 1 hours 2 1 Wednesday 1 hours 3 1 Thursday 1 hour How many more hours does Joel need to practice this week to meet his goal?

Joel need to practice this week = hour

Step-by-step explanation:

P.S - the exact question is -

As given

Total practice goal of Joel = hours

He practiced on : Monday - hours

                             Wednesday - hours

                             Thursday - 1 hour

Let the remaining practice = x hours

⇒ Total practice =   hours

⇒ + + 1 + x =

⇒ 1 +

⇒3 + x - 4 =

⇒x - 1 =

⇒x =

⇒x = hour

∴ we get

Joel need to practice this week = hour

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
