Answer:

Bonnie :

(0,12),(1,16)

Slope = (16 - 12) / (1 - 0) = 4/1 = 4

So Bonnie is adding $ 4 every week to her savings

Bobby :

y = 12x + 4

The slope here is 12.....so he is adding $ 12 every week to his savings

Therefore, the rate at which Bobbie is adding to his savings each week is (12 - 4) = $ 8 more then the rate at which Bonnie is adding to her savings account each week

Which number sentence represents the Commutative Property of Addition?

44 + 1 = 45
44 + 1 = 45

(16 + 2) + 18 = 16 + (2 + 18)
(16 + 2) + 18 = 16 + (2 + 18)

56 + 0 = 56
56 + 0 = 56

32 + 9 = 9 + 32

Answers

32 + 9 = 9 + 32 is the answer

The number which represent represents the Commutative Property of Addition will be;

⇒ 32 + 9 = 9 + 32

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expressions are,

44 + 1 = 45

(16 + 2) + 18 = 16 + (2 + 18)

56 + 0 = 56

32 + 9 = 9 + 32

Now,

We know that;

The rule of the Commutative Property of Addition is,

⇒ a + b = b + a

Hence, The correct number which represents the Commutative Property of Addition is,

⇒ 32 + 9 = 9 + 32

If l || m, m7 = 2x and m2 = x, then what is the measure of angle 2?

90°
30°
120°
60°

Answers

120
Since we first have to find out what x would be in both situations and then do an equation to figure out angle 2

An l || m, m7 = 2x and m2 = x, then what is the measure of angle 2 is 30°.

To find the measure of angle 2, use the properties of parallel lines and transversals.

Given that line l is parallel to line m, and we have two angles formed by a transversal intersecting these lines, angles 2 and 7.

are given that m7 = 2x and m2 = -1.

Since lines l and m are parallel, alternate interior angles are congruent. Therefore, angle 2 and angle 7 are congruent.

m2 = m7 (alternate interior angles are congruent)

Since m7 = 2x, substitute:

m2 = 2x

But, we are also given that m2 = -1, so set up an equation:

-1 = 2x

Now, solve for x:

x = -1/2

Now that have the value of x, find the measure of angle 2:

m2 = 2x

m2 = 2(-1/2)

m2 = -1

Therefore, the measure of angle 2 is -1 degree. However, it's worth noting that angles are typically measured as positive values, so the answer in this case would be 1 degree (considered as an acute angle). None of the multiple-choice options provided matches this answer exactly, but the closest one would be 30°.

When a flash of lightning occurs, the number of seconds elapsed until thunder is heard can be used to approximate the distance from the storm. The graph models this situation. Which equation can be used to approximate the distance from a storm, y , in miles, given the number of seconds, x , that has elapsed from the moment that a flash of lightning is seen to the time thunder is heard?

Answers

Pretty sure its C :)

After you see a flash of lightning, count the number of seconds until you hear the thunder. (Use the stop watch or count "One-Mississippi, Two-Mississippi, Three-Mississippi," etc.) For every 5 seconds the storm is one mile away. Divide the number of seconds you count by 5 to get the number of miles.

Within twoweeks, my neighborhood was bombarded with billboards. These billboards advertisedeverything from services to personal care products to businesses inappropriate for youngchildren. The billboards appeared on roads surrounding the neighborhood and in residentialparks. They are unsightly and hazardous to the residents in my neighborhood and theresidents of Blueville.Many of the residents find these billboards detract from the appeal and beauty of Blueville'sresidential neighborhoods. The giant billboards obscure the view of the natural beauty thatattracts visitors to Blueville. They hide our trees and damage flower fields near our parks.Many photographers and tourists visit Blueville for the beautiful scenery. However, thecosmetic and fitness services plastered on billboards disrupt the view. A decline in tourismwill hurt many local businesses.Not only are these billboards unappealing, but they are also hazardous to residents. Becausethe billboards are new to our city, many drivers are distracted by the images and newproducts and services that are advertised on them. Just within the first month, the number ofminor car accidents increased by 60 percent. There are new billboards at our busiestintersections, making turns extremely dangerous. The elementary school is at the corner ofBlueville Boulevard and Pine Oak Road, one of the city's busiest Intersections. Two newbillboards at this intersection make it difficult for drivers to pay close attention to studentscrossing the streets. Our students' safety surely is worth more than money from billboards.I understand that our city needs additional income. Last year, two factories relocated tobigger cities, and this severely hurt residents and negatively impacted the city's budget.Based on the previous meeting records, this new ordinance could help make up for the lostmoney from the factory closures. However, there are other ways of bringing in more moneyto the cityI recommend moving the billboards to downtown Blueville. Events such as sports,conferences, and concerts are all held in the stadiums and arenas located downtown. Thatwould be the perfect place for billboards.As Blueville leaders, it is crucial to ensure that your residents are heard and feel safe. It isessential to think about the future of Blueville and not just short-term monetary gains.
