The value of m which is an additive inverse of 58 is -58.
What numbers are additive inverses?Additive inverse is what you add to a number to make the sum zero. When two numbers are added together to get 0, then we say both the numbers are additive inverses of each other.
Since m is the additive inverse of 58, hence:
m + 58 = 0m = -58
The additive inverse of 58 is -58.

There are 38 empty parking spots and 12 full parking spots in the parking garage. What is
the ratio of the number of empty parking spots to the number of full parking spots?
Answer:
[tex]19:6[/tex]
Step-by-step explanation:
What is a ratio in math?
A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
So as per the question we have :-
38 empty parking spots
12 full parking spots
the ratio of the number of empty parking spots to the number of full parking spots can be expressed as :
[tex]= 38:12[/tex]
And by simplifying it to the shortest value possible we get it as

The distance between points (-6 , 4 ) and (-5 , -4 ) marked in the graph
is [tex]\sqrt{65}[/tex]
solution:From the given graph the two points are:
A = ( -6 , 4 ) , B = (-5 , -4 )
we have the distance from A to B ,
to find distance the formula is,
Distance = [tex]\sqrt{(x2 - x1)^{2} + (y2 - y1)^{2} }[/tex]
= [tex]\sqrt{(-5 - (-6))^{2} + (-4 -4)^{2} }[/tex]
= [tex]\sqrt{1^{2} + (- 8)^{2} }[/tex]

The missing side of the triangle is 7.2 units
How to find the missing side of a triangle?ABC is a triangle.
AD bisects(cut into half) the angle ∠BAC.
Therefore,
AB / BD = AC / DC
Hence,
AB = 12
BD = x
AC = 20
DC = 12
Therefore,
12 / x = 20 / 12
cross multiply
12 × 12 = 20x
144 = 20x

If −3+ n≤ 25, which inequality represents the possible range of values for 4n-12?
A) 4n-12≤ -100
B) 4n-12≤ 100
C) 4n-122-100
D) 4n-12≥100
The range is 4n - 12≤100.
The inequality is -3 + n≤25. From this, we can find the range of n.
n≤25 + 3
n≤28
Now we have to find the range of 4n - 12. For this, we have to ≤multiply both sides with 4 and then subtract it from 12, in the range of n.
That is;
4n≤ 28×4
4n - 12 ≤112 -12
4n - 12 ≤100

We know,
Total peanuts already in the mixture = 18 x [tex]\frac{62}{100}[/tex] = 11.16 kg
The new mixture contains 52% peanuts, then, [tex]\frac{x_{peanuts} }{x_{total} }[/tex] = 0.52.
Furthermore, 40% must be added.
[tex]x_{peanuts}[/tex] = [tex]0.4x[/tex] + [tex]11.16[/tex]
This gives us the following equation,
[tex]\frac{0.4x + 11.16}{18 + x } = 0.52[/tex]
Total mass =[tex]x + 18[/tex]
⇒ [tex]0.52 x +[/tex] 0.52 x 18 = [tex]0.4x + 11.16[/tex]

A shape is shown on the graph: A coordinate grid is shown from positive 8 to negative 8 on the x-axis and from positive 8 to negative 8 on the y-axis. A triangle is shown on ordered pair 2, negative 2 and 4, negative 2 and 2, negative 6. Which of the following is a reflection of the shape? (5 points) a A coordinate grid is shown from positive 8 to negative 8 on the x-axis and from positive 8 to negative 8 on the y-axis. A triangle is shown on ordered pair 2, 2 and 4, 2 and 2, 6. b A coordinate grid is shown from positive 8 to negative 8 on the x-axis and from positive 8 to negative 8 on the y-axis. A triangle is shown on ordered pair negative 2, negative 2 and negative 4, negative 2 and negative 4, negative 6. c A coordinate grid is shown from positive 8 to negative 8 on the axis and from positive 8 to negative 8 on the y-axis. A triangle is shown on ordered pair 2, 2 and 2, 4 and 6, 2. d A coordinate grid is shown from positive 8 to negative 8 on the axis and from positive 8 to negative 8 on the y-axis. A triangle is shown on ordered pair negative 2, negative 4 and negative 6, negative 4 and negative 6, negative 2.
The option which gives the reflection of the triangle (shape) with vertices, (2, -2), (4, -2), and (2, -6) is option a
a. A triangle is shown on ordered pair (2, 2), (4, 2), (2, 6)
What is a reflection transformation?A reflection transformation is one in which the line across which the object is reflected acts like a mirror, such that the points are swapped across the line of reflection.
The coordinates of the vertices of the triangle on the coordinate grid are;
(2, -2), (4, -2), and (2, -6)Required; The coordinates of a reflection of the shape (the triangle)
Solution; The coordinates of a point (x, y) following a reflection across the y–axis is (-x, y)
The vertices of the image of the triangle following a reflection across the y–axis are therefore;
(2, -2) → (-2, -2)(4, -2) → (-4, -2)(2, -6) → (-2, -6)A reflection of the point (x, y) across the x–axis gives the point (x, -y)
A reflection of the triangle across the x–axis therefore gives;
(2, -2) → (2, 2)(4, -2) → (4, 2)(2, -6) → (2, 6)A reflection of the point (x, y) across the line y = x, gives (y, x)
The vertices of the triangle following a reflection across the line y = x are therefore;
(2, -2) → (-2, 2)(4, -2) → (-2, 4)(2, -6) → (-6, 2)A reflection of the point (x, y) across the line y = -x, gives (-y, -x)
The vertices of the triangle following a reflection across the line y = -x are therefore;
(2, -2) → (2, -2)(4, -2) → (2, -4)(2, -6) → (6, -2)The coordinates of the triangle in the options are;
a) (2, 2), (4, 2), (2, 6)
b) (-2, -2), (-4, -2), (-4, -6)
c) (2, 2), (2, 4), (6, 2)
d) (-2, -4), (-6, -4), (-6, -2)
The correct option is therefore option a with points on the image of the triangle of (2, 2), (4, 2), (2, 6) which corresponds with the coordinates of the triangle following a reflection across the x–axis
