The solutions to the inequality -5 < 9 - 6x is x ≤ 7/3.
What is inequality?
In mathematics, the term 'inequality' is defined as a statement or equation with an ordered relationship like greater than, greater than or equal to, less than, less than or equal to- between two numbers or algebraic equations.
Now the given inequality is,
-5 < 9- 6x
Adding 5 both the side we get,
5 - 5 < 9 - 6x + 5
⇒ 0 < 14 - 6x
⇒ 14 - 6x > 0
Dividing both the side by 6 we get,
⇒ 14 < 6x
⇒ x > 14/6 = 7/3
or, x ≤ 7/3
this is the required solution of the given inequality.
Thus, the solutions to the inequality -5 < 9 - 6x is x ≤ 7/3.

Here is a linear equation: y = 2/3x + 1 Are (6, 5) and (9, 8) solutions to the equation? Explain or show your reasoning.
The equation y = 2/3x + 1 has a solution of (6, 5) and not (9, 8)
How to determine if the ordered pairs are part of the solutions?From the question, the equation is given as
y = 2/3x + 1
Also, we have the ordered pairs to be
(6, 5) and (9, 8)
For (6, 5), we have
x = 6 and y = 5
So, the equation becomes
5 = 2/3 x 6 + 1
Evaluate
5 = 5 --- true
For (9, 8), we have
x = 9 and y = 8
So, the equation becomes
8 = 2/3 x 9 + 1
Evaluate
8 = 7 --- false
Hence, (6, 5) is part of the solution and (9, 8) is not

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
Hence the length is 16.6ft and the width is 8.9ft

x = 36 + 45
x = 81°
As per figure 7,
By the property of Equilateral Triangles
⇒ x = 180 - 58

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.
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

The cups of sugar needed is 2.5 cups.
The cups of flour needed is 3.75 cups
The cups of butter needed is 1.25 cups.
How much sugar, flour and butter is needed?Given the information in the question, the ratio of sugar to flour to butter is 1 : 1.5 : 0.5
Cups of sugar needed = (ratio representing sugar / sum of ratios) x total number of cups
Sum of ratios = 1 + 1.5 + 0.5 = 3
Cups of sugar needed = (1 / 3) x 7.5 = 2.5 cups
Cups of flour needed = (ratio representing flour / sum of ratios) x total number of cups
Cups of flour needed = (1.5 / 3) x 7.5 = 3.75 cups

solve for v: -28 = v +-12
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
