M4 and m2 are equivalent
M2 and m3 are supplementary angles which mean they add up to 180°
M2+m3=180
Plug in the equation
3x+74+2x+11=180
Add up the x’s 3x+2x=5x
Add the constants on the left side
74+11=85
You get 5x+85=180
Subtract 85 from both sides
5x=95
Divide by 5
X=19
Now plug x into the m3 equation and get
2*19+11=49°
Because m4=m3, m4=49°
M3 and m1 are equivalent so set both equations equal to each other and solve bringing the same variables on each side
11x-9=7x+23
11x-7x=23+9
4x=32
X=8
Now plug x into either equation and you get
M3=79°

OPTION B IS YOUR ANSWER.
You know its a quadratic when the second difference of each y value is same.
Here's what I mean.
Option B
First all x values differ by 1. So we're good on those.
Now for the y values
Which are
3, -1, -3, -3, -1
find the difference between the second and first fod each... Then do this a second time.
If it gives the same value for all the second differences... Then its quadratic.
-1-3 = -4
-3-(-1) = -3 + 1 = -2
-3-(-3) = -3 + 3 = 0
-1-(-3) = -1 + 3 = 2.
The values are -4, -2, 0, 2.
Now find the difference of these(2nd - 1st)
-2-(-4) = -2 + 4 = 2
0-(-2)= 0 + 2 = 2
2 - 0 = 2
Since all second differences gave 2 as their answer....
Option B is your Quadratic Function!!!
Hope this helps!
Answer:
No, but x = 4
Step-by-step explanation:
3(7) + 8 - 7 = 5(7) - 4
21 + 8 - 7 = 22
22 = 35 - 4
22 = 31
It is not
How this equation may work is by subtracting the numbers by each side
3x + 8 - x = 2x + 8
2x + 8 = 5x - 4
-8 -8
2x = 5x - 12
-5x -5x
-3x = -12
x = 4
Answer:
First, you have to multiply 24 and 36 inches- that = 864. Then, you multiply 6 and 4- that = 24. Lastly, you divide 864 and 24- that= 36
