Step-by-step explanation: You have to substitute the numbers in for x & y

(0, -5): YES

3x - 4y - 8 = 12

3(0) - 4(-5) - 8 = 12

0 + 20 - 8 = 12

20 - 8 = 12

12 = 12

(4, -2): YES

3x - 4y - 8 = 12

3(4) - 4(-2) - 8 = 12

12 + 8 - 8 = 12

20 - 8 = 12

12 = 12

(8, 2): NO

3x - 4y - 8 = 12

3(8) - 4(2) = 12

24 - 8 = 12

16 = 12

(-16, -17): YES

3x - 4y - 8 = 12

3(-16) - 4(-17) - 8 = 12

-48 + 68 - 8 = 12

20 - 8 = 12

12 = 12

(-1, -8): NO

3x - 4y - 8 = 12

3(-1) - 4(-8) = 12

-3 + 32 = 12

29 = 12

(-40, -34): NO

3x - 4y - 8 = 12

3(-40) - 4(-34) - 8 = 12

-120 + 136 - 8 = 12

16 - 8 = 12

8 = 12

Hope this help you!!! :)

What is the value of the expression i0•i1•i2•i3•i4

My name is Ann [436]

$\bf \stackrel{1}{i^0}\cdot \stackrel{i}{i^1}\cdot \stackrel{-1}{i^2}\cdot \stackrel{-i}{i^3}\cdot \stackrel{1}{i^4}\implies i\cdot i\cdot 1\implies i^2\implies -1$

Consider the function. What is the y-intercept of f–1(x)? –16 –12

Mekhanik [1.2K]

<h2>Explanation:</h2><h2></h2>

Hello! Remember you have to write clear questions in order to get good and exact answers. Here, I'll assume the function as:

$f(x)=x^2+2x-16$

The y-intercept of a function is the point at which the graph of the function touches the y-axis. This occurs when we set $x=0$ . In other words, we define the y-intercept (let's call it $b$ as:
