Answer:
<h2>y = 4x + 5 and y = 4x - 5</h2>
Step-by-step explanation:
(1) y = 4x + 5 and (2) y = 4x - 5
substitute (1) to (2):
4x + 5 = 4x - 5 <em>subtract 4x from both sides</em>
5 = -5 FALSE (no solution)
(1) y = 4x + 5 and (2) 2y = 8x + 10
substitute (1) to (2):
2(4x + 5) = 8x + 10 <em>divide both sides by 2</em>
4x + 5 = 4x + 5 <em>subtract 4x from both sides</em>
5 = 5 TRUE (infinitely many solutions)
(1) y = 4x + 5 and (2) y = x + 5
substitute (1) to (2):
4x + 5 = x + 5 <em>subtract 5 from both sides</em>
4x = x <em>subtract x from both sides</em>
3x = 0 <em>divide both sides by 3</em>
x = 0
Put it to (2):
y = 0 + 5 = 5
One solution (0, 5)
(1) y = 4x + 5 and (2) y = 8x + 10
substitute (1) to (2):
4x + 5 = 8x + 10 <em>subtract 5 from both sides</em>
4x = 8x + 5 <em>subtract 8x from both sides</em>
-4x = 5 <em>divide both sides by (-4)</em>
x = -1.25
Put it to (1):
y = 4(-1.25) + 5 = -5 + 5 = 0
One solution (-1.25, 0)

Answer:
6.3°
Step-by-step explanation:
![\because \: \pi^{c} = 180 \degree \\ \\ \therefore \: 1^{c} = \frac{180 \degree }{\pi} \\ \\ \therefore \: 0.11^{c} = \frac{180 \degree }{3.14} \times 0.11 \\ \\ \therefore \: 0.11^{c} = \frac{180 \degree }{314} \times 11 \\ \\ \therefore \: 0.11^{c} = \frac{1980 \degree }{314} \times 11 \\ \\ \therefore \: 0.11^{c} = 6.30573248\degree \\ \\ \huge \red{ \boxed{\therefore \: 0.11^{c} = 6.3\degree }} \\ \\](https://tex.z-dn.net/?f=%20%5Cbecause%20%5C%3A%20%5Cpi%5E%7Bc%7D%20%20%3D%20180%20%5Cdegree%20%5C%5C%20%20%5C%5C%20%20%5Ctherefore%20%5C%3A%201%5E%7Bc%7D%20%20%3D%20%20%5Cfrac%7B180%20%5Cdegree%20%7D%7B%5Cpi%7D%20%20%5C%5C%20%20%5C%5C%20%20%5Ctherefore%20%5C%3A%200.11%5E%7Bc%7D%20%20%3D%20%20%5Cfrac%7B180%20%5Cdegree%20%7D%7B3.14%7D%20%20%20%5Ctimes%200.11%20%5C%5C%20%20%5C%5C%20%5Ctherefore%20%5C%3A%200.11%5E%7Bc%7D%20%20%3D%20%20%5Cfrac%7B180%20%5Cdegree%20%7D%7B314%7D%20%20%20%5Ctimes%2011%20%5C%5C%20%5C%5C%20%20%5Ctherefore%20%5C%3A%200.11%5E%7Bc%7D%20%20%3D%20%20%5Cfrac%7B1980%20%5Cdegree%20%7D%7B314%7D%20%20%20%5Ctimes%2011%20%5C%5C%20%5C%5C%20%5Ctherefore%20%5C%3A%200.11%5E%7Bc%7D%20%20%3D%206.30573248%5Cdegree%20%20%5C%5C%20%20%5C%5C%20%20%20%5Chuge%20%5Cred%7B%20%5Cboxed%7B%5Ctherefore%20%5C%3A%200.11%5E%7Bc%7D%20%20%3D%206.3%5Cdegree%20%7D%7D%20%5C%5C%20%20%5C%5C%20)
Answer:
