Step-by-step explanation:
The statement is true, because when we multiply or divide both sides of an inequality by the same negative number we reverse the inequality symbol.
What is Inequality?A relation by which we can compare two or more mathematical expression is called an inequality.
Let an example of the inequality as;
⇒ 2x < 3
Multiply by - 1, we get;
⇒ - 2x > - 3
Thus, When we multiply or divide both sides of an inequality by the same negative number we reverse the inequality symbol.

Write a compound inequality that represents the Fahrenheit temperatures between 50 degrees Celsius and 70 degrees Celsius.
Answer:
112 ≤ T ≤ 158
Step-by-step explanation:
We need to convert the celsius temperature to Fahrenheit first.
The formula to use is
F = (C * 9/5) + 32
For 50 degrees Celsius
F = (50 * 9/5) + 32
= 90 + 32 = 112 F
For 70 degrees Celsius
F = (70 * 9/5) + 32
= 158 F
So the compound inequality is written as follows;
112 ≤ T ≤ 158

what is the value of 4(x-2)(x-3)+7(x-2)(x-5)-6(x-3)(x-5) when x=5
Answer:
The value is 24
Step-by-step explanation:
We want to find the value of the given expression when x = 5
Simply substitute 5 into the given expression.
Thus, we have;
4(5-2)(5-3) + 7(5-2)(5-5) - 6(5-3)(5-5)
Any part of the expression with 5-5 will be zero and will cancel out
Thus, we have
4(3)(2) = 4 * 3 * 2 = 24
The required value of equation at x = 5 is 24.
Given ;
Equation is = 4(x-2)(x-3) + 7(x-2)(x-5) - 6(x-3)
We have to calculate the value of expression when x = 5
To solve the equation substitute x = 5 in the given equation
= 4(x-2)(x-3) + 7(x-2)(x-5) - 6(x-3)(x-5)
= 4(5-2)(5-3) + 7(5-2)(5-5) - 6(5-3)(5-5)
Simplify the equation
= 4(3)(2) + 7(3)(0) - 6(2)(0)
= 4.(6) + 7(0) - 6(0)
= 24 + 0 - 0
= 24
The required value of the equation at x = 5 is 24.

Line m passes through (5,-3) and is parallel to a line that passes through (1,-4) and (9,-2).
The required equation of the line is given as y =1/4x -17/4.
What is the slope of the line?The slope of the line is a tangent angle made by line with horizontal. i.e. m = tanx where x in degrees.
The slope of the line is given as,
m = (y₂ - y₁) / (x₂ - x₁)
Substitute the value in the above equation,
m = -2 + 4 / 9 - 1
m = 2 / 8
m = 1/4
Since the slope of the parallel lines is equal,
The equation of the parallel is given as,
y - y₁ = m (x - x₁)
Substitute the point in the equation,
y + 3 = 1/4(x - 5)
y = 1/4x - 5/4 -3
y =1/4x -17/4
Thus, the required equation of the line is given as y =1/4x -17/4.

y = –3/8x − 6/5
Answer:
-3/8
Step-by-step explanation:
This equation is formatted as y=mx+b where m is the slope of the line, x is the x value, and b is the y-intercept. When finding the slope of such an equation, just find what the coefficient of x in the function is. So, this equation is y = -3/8x - 6/5 and m is -3/8, so your slope is -3/8. Hope that helps!

1.) A ladder is leaning against the side so that the distance on the ground between
the base and the house is 7 feet.
If the ladder is 15 feet long, then what is the angle at which the ladder is leaning?
Answer:
62.182°
Step-by-step explanation:
Using cos and sin you are able to find the height of the ladder from the bottom of the house to the place the top of the ladder is. You can do this by making a triangle. By using the lengths and angles already present you are able to find all angles of the triangle.
The angle at which the ladder is leaning is 62.18°.
What is trigonometry?Trigonometry is the branch of mathematics that deals with calculating the angles of triangles or the lengths of their sides. It mainly concerned on the properties of right angled triangle.
For the given situation,
The length of the ladder = 15 feet
The distance between the house and the ladder base = 7 feet
The angle at which the ladder is leaning can be found by using trigonometric ratio, cos θ.
we know that, [tex]cos[/tex] θ = [tex]\frac{Base}{Hypotenuse}[/tex]
The figure below shows the relationship between the sides.
⇒ [tex]cos[/tex] θ = [tex]\frac{7}{15}[/tex]
⇒ θ = [tex]cos^{-1}(\frac{7}{15} )[/tex]
⇒ θ = [tex]62.18[/tex]
Hence we can conclude that the angle at which the ladder is leaning is 62.18°.

A full line must be 180 degrees and you already know that part of the line is 66 degrees. You do 180 minus 66 which gives you 114. That is the other unknown angle but it is asking for x, not the angle. You do 114 divided by 6 to get 19. Therefore, x=19.
