Answer 1

Answer:

Part A: The equations are:

y = -1/2x + 2, and

y = 3x - 5

Part B: The solution is (2,1)

Step-by-step explanation:

Part A: There are two equations we need to find, each line is the graph of a function.Graphs are written in y = mx + b, m is the slope, which is the change in y divided by the change in x, and b is the y - intercept. To find the function of the first graph, the one going slightly down, the slope is: y goes down by one, and x increases by 2, so change in y/ change in x is -1/2. The y - intercept is where the graph goes through the point where x is 0, on this graph, the point is (0,2), the y - intercept is 2, so y = mx + b is y = -1/2x + 2

For the other equation, slope is when y increases by 3, x increases by 1, so 3/1, or 3. The y - intercept is -5, so y = 3x + (-5), or y = 3x - 5

Part B: The solution to this equation is the point where both of the functions meet, here, this point is (2,1), y is 2 and x is 1.

The drama club sold 415 Manatee tickets to the school's play for $7.95 each 18 of the tickets were refunded estimate the tickets is your estimate and overestimate or an underestimate. PLZ HELP ASAP!!!!!!

Answers

since you always round up when you estimate in the middle lets say theres 420 tickets. Each is 7.95, but we'll round it to 8.00. 420x8.=3,360. After that part we need to find about how much tickets were refunded. So we round 18 to 20 and each ticket is still 8$. 20x8=160. Finally in all, we do 3,360-160=3200. Its an overestimate because we rounded up. Im not sure what else youre asking but thats the basic answer.

What is a good newspaper article?

Good research and the right organizational structure are the key constituents of writing an impactful newspaper article. Besides that, elements like interesting lead, catchy headlines, bylines, and good additional information are the basic parts of a successful newspaper article.

Since, News articles are written in a structure known as the “inverted pyramid.”

In the inverted pyramid format, the most newsworthy information goes at the beginning of the story and the least newsworthy information goes at the end.

Can someone give me a small lesson on nets and surface areas??

Thank you if you can. I really don’t understand.

Answers

Hi!

Here is the definition of a net from www.icoachmath.com:

“Net is a two-dimensional pattern of a three-dimensional figure that can be folded to form the figure. In other words, net is a flattened three-dimensional figure which can be turned into the solid by folding it.”

In the photo is an example of a net of a rectangular prism.

Surface area is the measure of the total area of the surface of a 3D object. For example, if I have a cube, the surface area would be the area of the outside of the cube.

Hope this helped,
