<u>Add 7 on both sides</u>

-b - 7 + 7 = -15 + 7

-b = -8

-b / -1 = -8 / -1

b = 8

Given the points below, find XY. Round to<br> the nearest hundredth.<br> X(-8, 2) and Y(7,-4)
Tasya [4]

Answer: 16.16  

Step-by-step explanation:

xy in this situation, will be the distance between the two points.

(-8,2) (7,-4)    Find the distance between the points

To ind the distance, find the difference in the x and y values,square them and add them to find the obtained number square root.

2-(-4) =  6

-8 - 7 = -15

6^2 + (-15)^2 = d^2 where d is the distance

36 + 225 = d^2

 261 = d^2

d= \sqrt{261}

d= 16.1554  rounded to the nearest hundredth is 16.16

Ben earns $10 per hour and $6 for each delivery he makes. He wants to earn more than $155 in an 8-hour workday. What is the leas
monitta

Answer:

the number of deliveries would be 13

And, the equation is d ≥ 12.50

Step-by-step explanation:

The inequality function is given below:

Let us assume the d be the number of deliveries

10 × 8 + 6 × d ≥ 155

80 + 6d ≥ 155

6d ≥ 155 - 80

6d ≥ 75

d ≥ 75 ÷ 6

d ≥ 12.50

hence, the number of deliveries would be 13

And, the equation is d ≥ 12.50
