Answer: y=Mx+b

Step-by-step explanation:

I'm learning this in class right now lol The answer is y=mx+b. enjoy ur day/night! :3

Given the following system of linear equations, do Part A and Part B below.
(3x=3y-3
(y=x+1 Part A: Using the method of your choice (graphing, substitution or addition), find the solution to the system of linear equations. Include all of your work in your final answer. Part B: In two or more complete sentences, explain why you chose the specific method you used to find the solution to the system.

Answers

Answer: (0, 1)

Step-by-step explanation:

For starters, the two equations are the same line if you put the first one into y=mx+b form you'll see that they are, so basically any solution to one is the same for the other.

I choose subsitution to find the solution set

[tex]3x = 3y -3\\y = x + 1 \\3x = 3(x+1) -3 \\3x = 3x + 3 -3 \\3x - 3x= 3-3 \\x = 0 \\\\y = x+ 1\\y = 0 +1 \\y = 1[/tex]

This method is the easiest given that the problem already tells you what y is equal to. So this way you can substitute this in for y in the first equation and find x and then from there find y in the second.

Alright so A triangles perimeter is always going to be 90°

So for #1 You would add 18+24= 42 then subtract 42 from 90. 90-42=48. So for the first equation the side would be 48ft.

And for #2 You add 41+40= 81 then subtract 81 from 90 90-81=9 so the answer to the second equation would be 9 ft.

Hope this helps! :)

Answer:

Step-by-step explanation:

a² + b² = c² (pythagorean theorem formula)

let's take 18 as a and 24 as b

So, you'll write it as

18² + 24² = c²

324 +  576 = 900²

c² =810000

c= [tex]\sqrt810000[/tex] = 900

c=900ft

Answers

Answer:

x= 22.6

Step-by-step explanation:

This little red square means that is a right angle (90 degrees)  

x is the complementary of 67.4  (Both add to 90)

90-67.4 = 22.6

that type of corner angle is a 90° angle, so since you know the first half of the 90° angle which is 67.4 all you need to do is subtract

so you get
90 - 67.4 = 22.6

B. 31.5 ft^2 because you find the area of each rectangle and add them and then find the area of the triangle and add it in to get 31.5 ft^2
3 x 5 = 15ft
3 x 4 = 12ft
3 x 3 = 9 divided by 2 = 4.5
15 + 12 + 4.5 = 31.5 ft
