Choose the linear inequality that describes the graph. The gray area represents the shaded region.
4x – 6y ≥ 10
4x + 6y ≤ 10
4x + 6y ≥ –10
4x + 6y ≥ 10
please help !
Answers
Answer:
4x+6y<=10
Step-by-step explanation:
The linear inequality that describes the graph is 4x+ 6y ≤ 10.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
As, The bold straight line passes through the points (1,1) and (-2, 3).
so, equation of line will be
(y- 1) = (3-1)/ (-2-1) (x-1)
y-1 = 2 / (-3) (x-1)
-3y + 3 = 2x - 2
-3y -2x = -5
If we multiply by 2 both side we get
-6y - 4x = -10
4x+ 6y= 10
So, the required inequality for gray area is 4x+ 6y ≤ 10.

What would be the best method to solve
the system of equations below?
6x + 3y = 21
2x – 3y = -13
Answers
You can isolate the y value by subtracting the x to the other side. All the numbers have 3 in common, so you need to divide all of them by 3. I would then substitute the new equation into the 2x-3y=-13, making it 2x-3(-2x+7)=-13
You wove the equation, and once you get your x value, you needles to substitute it in the equation: y=-2x+7
The final answers will be x=1 and y=5
Elimination method is the best method to solve the system of equations below
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given system of equations
6x + 3y = 21...(1)
2x – 3y = -13...(2)
Add equations (1) and (2)
6x+3y+2x-3y=21-13
8x=8
Divide both sides by 8
x=1
Now plug in x value in equation 1
6+3y=21
Subtract 6 from both sides
3y=15
Divide both sides by 3
y=5
By Elimination method we find the values of x and y.
Hence, Elimination method is the best method to solve the system of equations below

23. Describe the slopes of perpendicular lines
Answers
Answer:
The slopes of two perpendicular lines are negative reciprocals of each other. This means that if a line is perpendicular to a line that has slope m, then the slope of the line is -1 / m. For example, we found that the slope of the line y = (1/2)x + 3 is 1/2.
The slopes of perpendicular lines when multiplied together gives the product as -1.
What is the slope of straight line?The slope of a straight line is the tangent of the angle formed by it with the positive x axis as the reference.
The negative slope indicates the rate of decrease while the positive shows the rate of increase.
Suppose the two perpendicular lines have equations as follows,
y = m₁x + c₁ and y = m₂x + c₂.
Suppose m₁ = tan θ
Then, m₂ = tan (90° + θ)
Apply the trigonometric identity to obtain,
m₂ = tan (90° + θ) = -cot θ
Now, m₁ × m₂ = tan θ × -cot θ = -1
Thus, the products of slopes is -1.
Hence, the product of slopes of two perpendicular lines is -1.

Three angles are in the ratio 2:3:5
The smallest angle is 50
Work out the sizes of the other two angles
Answers
Answer:
The other two angles are 75° and 125°.
Step-by-step explanation:
Let three angles are 2x, 3x and 5x.
The smallest angle is 50.
It means,
2x = 50
x = 25
So,
3x = 3(25) = 75°
5x = 5(25) = 125°
So, the other two angles are 75° and 125°.

1&2 are supplementary angles, so
3x+12x= 180

x= 12°
measure of angle 4 equals the measure of angle 2
because they're head opposite angles
