2. ![\displaystyle y = -\frac{5}{7}x + 2](https://tex.z-dn.net/?f=%5Cdisplaystyle%20y%20%3D%20-%5Cfrac%7B5%7D%7B7%7Dx%20%2B%202)
1. ![\displaystyle y = -2x + 4](https://tex.z-dn.net/?f=%5Cdisplaystyle%20y%20%3D%20-2x%20%2B%204)
Step-by-step explanation:
3. 2x - 5y = −7
- 2x - 2x
__________
![\displaystyle \frac{-5y}{-5} = \frac{-2x - 7}{-5} \\ \\ y = \frac{2}{5}x + 1\frac{2}{5}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cfrac%7B-5y%7D%7B-5%7D%20%3D%20%5Cfrac%7B-2x%20-%207%7D%7B-5%7D%20%5C%5C%20%5C%5C%20y%20%3D%20%5Cfrac%7B2%7D%7B5%7Dx%20%2B%201%5Cfrac%7B2%7D%7B5%7D)
2. 5x + 7y = 14
- 5x - 5x

Answer:
#11-13: 118 , 97 , 62
#7-10: 92 , 125 , 56 , 130
Step-by-step explanation:
#11. Supplementary angles (A + B = 180)
- (n + 7) + (3n - 47) = 180
- n = 55
- <ABC = 3(55) - 47 = 118 degrees
#12. Supplementary angles
- 83 + x = 180
- x = 97
- <ABC = 97 degrees
#13. Congruent angles (A = B)
- (8x - 34) = (5x +2)
- x = 12
- <DEF = 5 (12) + 2 = 62 degrees
#7. Congruent angles
- (3x +23) = 4x
- x = 23
- <ABC = 4(23) = 92 degrees
#8. Congruent angles
- 5x = (3x + 50)
- x = 25
- <MPQ = 3(25) + 50 = 125 degrees
#9. Congruent angles
- (a + 28) = 2a
- a = 28
- <MNP = (28) + 28 = 56 degrees
#10. Congruent angles
- 5y = (2y + 78)
- y = 26
- <WXZ = 5(26) = 130 degrees
I hope this helps!
Answer:
Zero
Step-by-step explanation:
Step-by-step explanation:
Step 1: Plot the points
L(1,2)
M(0,-1)
J(1,-2)
K(2,-1)
Step 2: Multiply each point by 5.
and record thise points so we have
L(5,10)
M(0,-5)
J(5,-10)
K(10,-5)
Step 3: Plot those points.
