solve for v: -28 = v +-12
Answers
Answer:
v = -16
Step-by-step explanation:
Move the variable to the left-hand side and change its sign, so it would then be -28 - v = -12
Then move the constant to the right-hand side and change its sign, so it would become - v = -12 + 28
Then you would calculate the sum: - v = 16
After doing so, change the sides on both sides of the equation, v = -16
So, your answer should be v = -16

Complete the empty table from the provided information.
Transform the graph of f(x) by dilating it by a factor of -2 and then shift it up 3.
Write the equation of the resulting line in slope intercept form.
Answers
The empty table should be completed with the coordinates of the transformed graph after a dilation with a scale factor of 3 as follows;
x m(x)
4 -2
2 -1
0 0
-2 1
-4 2
The equation of the resulting line in slope-intercept form is y = -0.5x + 3.
How to transform the graph of f(x) through dilation?Based on the given coordinates of the graph of function f(x), the dilation with a scale factor of 3 from the origin (0, 0) or center of dilation would be calculated as follows:
Point 1 (-2) → Point 1' (-2 × -2) = Point 1' (4).
Point 2 (-1) → Point 2' (-1 × -2) = Point 2' (2).
Point 3 (0) → Point 3' (0 × -2) = Point 3' (0).
Point 4 (1) → Point 4' (1 × -2) = Point 4' (-2).
Point 5 (2) → Point 5' (2 × -2) = Point 5' (-4).
Next, we would translate the graph of function f(x) 3 units up as follows:
Point 1 (-2) → Point 1' (-2 + 3) = Point 1' (1).
Point 2 (-1) → Point 2' (-1 + 3) = Point 2' (2).
Point 3 (0) → Point 3' (0 + 3) = Point 3' (3).
Point 4 (1) → Point 4' (1 + 3) = Point 4' (4).
Point 5 (2) → Point 5' (2 + 3) = Point 5' (5).
Now, we can determine the slope of the transformed graph:
Slope, m = Δy/Δx
Slope, m = (y₂ - y₁)/(x₂ - x₁)
Slope, m = (2 - 1)/(2 - 4)
Slope, m = -1/2 or -0.5
Mathematically, the slope-intercept form of a straight line is given by;
y = mx + c
Where:
x and y are the points.m represents the slope.c represents the y-intercept.At point (2, 2) and y-intercept c = 3, we have:
y = mx + c
y = -0.5x + 3

Answers
1. The inequality for the statement is C. f minus 7 over 8 is greater than negative 2 over 3
2. The value of the expression is C. 43 over 24 times j plus 1 over 12.
3. −0.28x − 15.3 = 1.92 will be B. -61.5.
What is the inequality?1. The difference between a number and seven eighths exceeds negative two thirds is:
Let the number be f.
This will be:

= -43/24j + 1/12
3. −0.28x − 15.3 = 1.92
Collect like term
−0.28x = 1.92 + 15.3
-0.28x = 17.22

Negative just flips over the equation.

Step-by-step explanation:
Zero Exponent Property: The zero exponent rule states that when a nonzero number is raised to the power of zero, it equals 1.
Example: x^0 = 1
Negative Exponent Properties: the negative exponent rule tells us that a number with a negative exponent should be put to the denominator, and vice verse. It also describes how many times we have to multiply the reciprocal of the base.

The length is 16.6ft and the width is 8.9ft
Area of the rectangular area = Length × width
A = LW … 1
What is the explanation?If he wants to have a rectangular area of turf with length one foot less than 3 times the width, then
L = 3W - 1 … 2
Substitute 2 into 1
A = (2W-1)W
A = 2W^2 - W
Since area = 150sq.ft
150 = 2W^2 - W
2W^2 - W - 150 = 0
Factorize
2W^2 - W - 150 = 0
W = 1±√1+4(300)/2(2)
W = 1±√1201/2(2)
W = 1±34.655/4
W = 35.655/4
W = 8.91375
W = 8.9 (to nearest tenth)
Get the length
L = A/W
L = 150/8.9
L = 16.85
L = 16.6ft

This is using 3.14 for pi and rounded to tenths
Step by step
First we will find the diagonal by using Pythagorean theorem a^2 + b^2 = c^2
We know the a & b sides, looking for c the hypotenuse or diagonal
40^2 + 70^2 = c^2
1600 + 4900 = c^2
6500 = c^2
80.6 = c = the full diagonal length.
Now we know the circle has a diameter of 10, so we subtract that from the diagonal length.
80.6 - 10 = 70.6m
Now we need to find the circumference of the circle using C = 2 TT r
We know the diameter is 10, so radius is half of that, so r=5
C = (2) (3.14) (5)
C = 31.4
Since we walk only half of the circle to get from A to C, we divide our circumference by 2.
31.4 / 2 = 15.7
So we have diagonal length of 70.6 + half the circle 15.7 for a total of 86.3m for the path as highlighted on the attachment

The range of the function f (x) = -3x are (0, -3, 6).
What is Domain?
The set of all inputs of the function is called Domain of set.
Given that;
The domain of f(x) = -3x is (0, 1, 2).
Now, Domain of the function are the values of x.
So, We find the Range of the function as;
Substitute all the values of domain (x) in the given function as;
The function is;
f (x) = -3x
For x = 0
Range = f (x) = - 3 × 0 = 0
For x = 1;
Range = f (x) = - 3 × 1 = -3
For x = 2
Range = f (x) = 3 × 2 = 6
Thus, Range of the function are (0, -3, 6)

What are the Equilateral Triangles?
In any equilateral triangle, the three angles are of equal measure and they equal 60 degrees.
As per figure 4,
x° + 56° + 90° = 180
x = 180 - 146
x = 34°
As per figure 5,
x = 57°
As per figure 6,
36 + 90/2 + 180-x = 180
36 + 45 - x = 180 - 180
x = 36 + 45
x = 81°
As per figure 7,
By the property of Equilateral Triangles
⇒ x = 180 - 58
⇒ x = 122°
As per figure 8,
By the property of Isosceles Triangles
x + 115 = 180
x = 180 - 115
x = 65°
As per figure 9,
6 + x + 60 + 60 = 180
x = 180 - 60 - 60 - 6
x = 54°
As per figure 10,
By the property of Equilateral Triangles
60/2 + 60 + x = 180
x = 180 - 60 - 30
x = 90°
As per figure 11,
By the property of Equilateral Triangles
2(30) + 60 + x = 180
x = 180 - 60 - 60
x = 60°
As per figure 12,
