Answer:

38°

Step-by-step explanation:

All triangles have a sum of 180°

180 - (119 + 23) = missing angle

180 - (142) = missing angle

38 = missing angle

So, the missing angle has a measurement of 38°

What is the distance from the points (6,10) to the line y=-x to the nearest tenth

sergiy2304 [10]

<span>points (6,10)
</span>y = -x
x + y = 0

distance = lax1 + by1 + cl/√(a^2 + b^2)
= l1(6) + 1(10) + 0l/√(1^2 + 1^2)
= l6 + 10 + 0l/√(1 + 1)
= l16l/√2
= 16/√2
= 8 .2/√2
= 8 . √2.√2/√2
= 8√2

If the domain of a function that is reflected over the x-axis is (1, 5), (2, 1), (-1, -7), what is the range?

Tju [1.3M]

Answer:

A. (1, -5), (2, -1), (-1, 7)

Step-by-step explanation:

Reflecting a function over the x-axis:

When a function is reflected over the x-axis, the x-value stays the same, while y changes the signal, so the transformation rule is:

$(x,y) \rightarrow (x,-y)$

To find the range:

We apply the transformation to the points in the domain. Thus:

$(1,5) \rightarrow (1,-5)$

$(2,1) \rightarrow (2,-1)$

$(-1,-7) \rightarrow (-1,-(-7)) = (-1, 7)$

Thus the correct answer is given by option a.
