<h3>hello!</h3>

We're given a point that the line intersects and its slope.

Let's use Point-slope:-

\boxed{y-y1=m(x-x1)}

y1 = -5

m=-5

x1=-1

\boxed{y-(-5)=-5(x-(-1)}

\boxed{y+5=-5(x+1)}

Convert to slope-intercept:-

\boxed{y+5=-5x-5}

\boxed{y=-5x-5-5}

Finally,

\bigstar{\boxed{\pmb{y=-5x-10}}

<h3>note:-</h3>

Hope everything is clear; if you need any clarification/explanation, kindly let me know, and I will comment and/or edit my answer :)

Let g(x, y) = cos(x + 5y). (a) Evaluate g(10, −2). g(10, −2) = (b) Find the domain of g. −1 ≤ x ≤ 1, − 1 5 ≤ y ≤ 1 5 −5 ≤ x ≤ 5,
RoseWind [281]

Answer:

since Cos(z) is a function defined for all z\in \mathbb{R}, then there is not restriction for x+5y, thus, the domain of g(x,y) is \mathbb{R}^2 and in interval notation is (-\infty,\infty)\times(-\infty,\infty)

Since Cos(x+5y)\in\mathbb{R} then the range of g(x,y) is the interval [-1,1].

Problem 10

<h3>Answer: 80 degrees</h3>

Work Shown: 80-0 = 80

You subtract the values on the protractor where the two angle arms line up.

============================================

Problem 11

<h3>Answer: 45 degrees</h3>

Work Shown: 45-0 = 45

Same idea as problem 10

============================================

Problem 12

<h3>Answer: 83 degrees</h3>

Work Shown: 128-45 = 83

Same idea as the others. The arm TS isn't fully on 130 degrees, and it's a bit short of it. It looks to be about 128 degrees or so.

============================================

Problem 13

<h3>Answer:  35 degrees</h3>

Explanation: Luis forgot to subtract the value of each arm of the angle. So he should have done 80-45 = 35. The answer would be 80 degrees if arm TQ was at 0 degrees (so 80-0 = 80), but instead TQ is at 45 degrees.
