Jason is incorrect, because inequality signs change when we multiply/divide by negative numbers, and we need to follow the signs to make sure we use the correct one.
Is Jason correct whit his claim?Well, Jason says that you can solve an inequality by replacing the sign by an equal sign, solve the equation as you already have done a thousand times, and then put the inequality sign again.
Now, this is clearly incorrect, because inequalities have a really nice property. If you multiply or divide both sides of the inequality by a negative number, then the "direction" of the sign changes.
This means that if we have an inequality like:
-2x > 10
And we divide both sides by -2, we should get:
x < 10/-2
x < -5
Where the direction of the sign changed.
If you did what Jason said, the direction of that sign would not have changed, and thus, you would have got an incorrect solution for the inequality.

Lines x and y intersect to form adjacent angles 2 and 3 . If m ∠2=3 a-27 and m∠3=2 b+14, find the values of a and b so that x is perpendicular to y.
Using the perpendicularity concept, the values of a and b so that x is perpendicular to y are: a = 39º, b = 38º.
What are perpendicular lines?Two lines are perpendicular if when they intersect two angles of 90º are formed.
Hence, the condition for this problem is given by:
m<2 = 90º.m<3 = 90º.From condition 2, the value of a is found as follows:
3a - 27 = 90º
3a = 117º
a = 117/3
a = 39º.
From condition 3, the value of b is found as follows:
2b + 14 = 90º
2b = 76º
b = 76/2
b = 38º.

A. When Steven buys 2.32 pounds of trial mix and 4.64 pounds of dry fruit, the cost is $27.84.
B. When Mario got $0.40 in change from buying trail mix The pounds bought will be 5.6 pounds.
How to illustrate the information?A. It should be noted that Steven buys 2.32 pounds of trial mix and 4.64 pounds of dry fruit. The cost will be:
= (2.32 × $3.50) + (4.64 × $4.25)
= $8.120 + $19.72
= $27.84
B. From the information, Mario got $0.40 in change from buying trail mix The pounds bought will be:
20 - 3.50x = 0.40
3.50x = 20 - 0.40
3.50x = 19.60

The equivalent expression for the expression (-5cd-4)(2cd²)² is - 20c³d⁵ - 16c²d⁴.
A finite combination of symbols that are well-formed in accordance with context-dependent principles is referred to as an expression or mathematical expression. Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Consider the expression,
(-5cd - 4)( 2cd²)²
Now let x = (-5cd - 4)( 2cd²)²,
Then,
x = (-5cd - 4)( 2cd²)²
x = ( - 5cd -4 ) × (2c)² × (d²)²
x = ( - 5cd - 4) × ( 4c² ) × d⁴
x = ( -5cd - 4 ) × 4c²d⁴
Using the distributive property,
x = ( - 5cd ) × ( 4c²d⁴ ) - 4 × 4c²d⁴
x = - 20 × c³ × d⁵ - 16 × c²d⁴
x = - 20c³d⁵ - 16c²d⁴

if angle a and angle b are supplementary angles and m∠a=x, which expressions represents the number of drgress in angle B? x-180, 180-x, x-90, 90-x
m∠b = 180° - x
That is the expression that represents the number of degrees of angle b.
Which expressions represent the number of degrees of angle B?
Two angles A and B are supplementary only if their measures add up to 180 degrees.
Then we can write the simple equation:
m∠A + m∠B = 180°
In this case, we know that we have two angles a and b that are supplementary, and the measure of angle a is equal to x, where x is a variable, then using the above equation we can write:
m∠a + m∠b = 180°
Replacing the measure of angle a by the variable we get:
x + m∠b = 180°
Solving this for the measure of angle b we get:
m∠b = 180° - x
That is the expression that represents the number of degrees of angle b.

The required line segment will terminate at the point on the graph where the airports' coordinates (x, y) are placed.
The graph's origin, or (0, 0), will serve as its initial coordinates. Kiley's home is represented by this point. You need to figure out where the line segment would terminate if you were to draw a segment from here that depicts Kiley's automobile travel from her residence to the airport.
What is Coordinate :Coordinates are a set of values which helps to show the exact position of a point in the coordinate plane. Coordinate Plane Meaning. A coordinate plane is a 2D plane which is formed by the intersection of two perpendicular lines known as the x-axis and y-axis.
Let the airports' coordinates be in this instance (x, y).
Moreover, if the slope of the line segment linking Kiley's home and the airport is m,
The line's equation will now be,
y = mx
c = 0
Because the line is passes from origin (0, 0)

A line that includes the points (c, -2) and (-1, 0) has a slope of -1/3 What is the value of c?
Answer:
c = 5
Step-by-step explanation:
Slope-intercept form of a linear equation:
[tex]\large\boxed{y=mx+b}[/tex]
where:
m is the slope.b is the y-intercept.Given:
Slope = -¹/₃Point = (-1, 0)Substitute the given slope and point into the formula and solve for b:
[tex]\begin{aligned}y & = mx + b\\\implies 0 & = -\dfrac{1}{3}(-1)+b\\0 & = \dfrac{1}{3}+b\\-\dfrac{1}{3}&=b\\ \implies b&=-\dfrac{1}{3}\end{aligned}[/tex]
Substitute the given slope and found value of b into the formula to create an equation for the line:
[tex]\boxed{y=-\dfrac{1}{3}x-\dfrac{1}{3}}[/tex]
Substitute the point (c, -2) into the equation and solve for c:
[tex]\begin{aligned} y&=-\dfrac{1}{3}x-\dfrac{1}{3}\\\implies -2&=-\dfrac{1}{3}c-\dfrac{1}{3}\\-2+\dfrac{1}{3}&=-\dfrac{1}{3}c-\dfrac{1}{3}+\dfrac{1}{3}\\-\dfrac{5}{3}&=-\dfrac{1}{3}c\\-\dfrac{5}{3} \cdot 3&=-\dfrac{1}{3}c \cdot 3\\-5&=-c\\\implies c & = 5\end{aligned}[/tex]
