1. 3x(4-9)+7x-5=303
2. 5(2x+3)+12x=17
3. 7(4x-4)-20=38

1. x= - 77/2 or -38-1/2

2. 1/11

3. 43/14 or 3 and 1/14

Step-by-step explanation:

1. 12x - 27x + 7x - 5 = 303

- 15x + 7x - 5 = 303

- 8x = 303 + 5

-8x = 308

x = - 38.5

2. 10x + 15 + 12x = 17

22x + 15 = 17

22x = 17 - 15

22x = 2

x = 0.0909090909

3.28x - 28 - 20 = 38

28x - 48 = 38

28x = 38 + 48

28x = 86

x = 3.07

Part A. The slope of f(x) is 4. I observed that each time the y value would increase by 4 points every time the x value increases by 1. The slope of g(x) is 2. I identified the m value as it's in slope-intercept form. The slope of f(x) is greater then that of g(x) because 4>2

Part B. The y-intercept of f(x) is greater. It is given that when x is 0, y is -1, so the y intercept of f(x) is -1. Meanwhile, the y-intercept of g(x) is -7 after identifying the b value. -7<-1, concluding that f(x) has a greater y-intercept
