The answer is B because to find the distance between a number from zero you need the absolute value in the expression here it’s -7+7

Answer:

Most likely C

Step-by-step explanation:

This is most likely C because it always goes up and although a and c are the only ones with positive equations a makes you multiply by a decimal which can reduce the number so it's most likely C

What is the value of the expression: 2 - (3x + 5y) if x = -3 and y = 4?
WARRIOR [948]
<h3>Hello there today we will solve your problem</h3>

here is our equation,

2-(3x+5y),

Now we will plug in our numbers

__________________

  1. {\boxed{x=-3}}
  2. {\boxed{y=4}

__________________

2-(3\cdot-3+5\cdot4)

simplify it and we get

2-(-9+20)

2-11

-9

A line intersects the points(-22,-14) and (-18,-12). What is the slope-intercept equation for this line?
zaharov [31]

Hello there,

Well we are going to start off with the equation to find the slope based on the given points:

                                                    \frac{y_{2} - y_{1}  }{x_{2} -x_{1} }

Now using the two given points we are going to plug in and solve:

                                         \frac{(-12)-(-14)}{(-18)-(-22)} = \frac{2}{4} = \frac{1}{2}

From this you know that \frac{1}{2} is the slope of the equation. However, to find the y-intercept we are going to use y = mx+ b and plug in one of the points to solve:

                                        (-14) = \frac{1}{2} (-22) + b

                                        (-14) = (-11) + b

                                         -3 = b

That means that the y-intercept is at (0, -3). Lastly, we are just going to plug all this into the slope-intercept form:

                                       y = \frac{1}{2} - 3

Hope I helped,

Amna
