Answers
3x - 9y = 10.8
3x - 9(0) = 10.8
3x = 10.8
x = 10.8/3
x = 3.6 or (3.6,0) <== ur x int
to find the y int, sub in 0 for x and solve for y
3x - 9y = 10.8
3(0) - 9y = 10.8
-9y = 10.8
y = -10.8/9
y = - 1.2 or (0,-1.2) <== ur y int
The x-intercept and the y-intercept of the line described by the equation 3x - 9y = 10.8 are 3.6 and -1.2
The x-intercept of a line is the point where y-coordinate is zero while the y-intercept of the line is the point where the x-coordinate is zero
Given the expression 3x - 9y = 10.8
Get the x-intercept. If y = 0
3x - 9(0) = 10.8
3x = 10.8
x = 10.8/3
x = 3.6
Get the y-intercept. If x = 0
3(0) - 9y = 10.8
-9y = 10.8
y = -10.8/9
y = -1.2
Hence the x-intercept and the y-intercept of the line described by the equation 3x - 9y = 10.8 are 3.6 and -1.2

Find the measure of ∠AED
Answers
I just did 3x+10=5x and solved it
Angles AEB and DEC are vertical angles, so their measures are equal.
5x = 3x + 10
2x = 10
x = 5
m<AEB = 5x = 5 * 5 = 25
Angle AED is supplementary to <AEB, so
m<AED + m<AEB = 180
m<AED + 25 = 180
m<AED = 155

The equation of line m is 4x+5y=−2. What is the slope of a line that is perpendicular to line m?
Answers
4x + 5y = -2
5y = - 4x - 2
y = -4/5 x - 2/5
the slope of this line is -4/5 and slope of line perpendicular to it is - 1 / -4/5
= 5/4 answer
The required slope of a line will be 5/4 which is perpendicular to line m.
What are the perpendicular lines?Perpendicular lines are two lines that cross one other and create a 90-degree angle. Two lines are perpendicular if the product of their slopes is -1.
The equation of line m is given in the question below as:
⇒ 4x + 5y = −2
We have to determine the slope of a line that is perpendicular to line m
First, we need to find the slope of line m
To convert to slope-intercept form
⇒ 4x + 5y = -2
⇒ 5y = - 4x - 2
⇒ y = -4/5 x - 2/5
So the slope of this line is -4/5 and the slope of a line perpendicular to it is
⇒ - 1 / (-4/5)
Reciprocal the terms in the numerator,
⇒ 5/4
Therefore, the required slope of a line will be 5/4 which is perpendicular to line m.

A car is traveling at a rate of 50 miles per hour. what is the car's rate in kilometers per hour? how many kilometers will the car travel in 3 hours? in your computations, assume that 1 mile is equal to 1.6 kilometers.
Answers
Final answer:
To convert 50 miles per hour to kilometers per hour, multiply by 1.6 to get 80 km/h. In 3 hours, the car will travel 240 kilometers.
Explanation:
The student is asking how to convert a car's speed from miles per hour (mi/h) to kilometers per hour (km/h), and then calculate the distance traveled in kilometers over a period of 3 hours.
Conversion from mi/h to km/h
To convert the car's speed from miles per hour to kilometers per hour, you can use the conversion factor that 1 mile is equal to 1.6 kilometers. Given the car's speed of 50 miles per hour, the calculation would be:
Speed in km/h = Speed in mi/h imes Conversion factor = 50 mi/h imes 1.6 km/mi = 80 km/h.
Distance Traveled in 3 Hours
Now, to compute the distance the car will travel in 3 hours at 80 km/h, use the formula:
Distance = Speed imes Time = 80 km/h imes 3 h = 240 kilometers.

is 2x-5y=10 a function ------is it linear or nonlinear?
Answers
It is linear when 2x- 5y = 10. A linear equation is an equation of a straight line, which means that the degree of a linear equation must be 0 Or 1.
How can we tell whether a function is linear or not?Looking at a function’s graph will reveal if it is linear or not with the greatest ease. When a linear function is plotted on a graph, a straight line is formed.
A nonlinear function Is curved in some way; it does not form a straight line.
How is a function defined as linear?The graph of a linear function is a straight line. One independent variable and one dependent variable make up a linear function.
X and Y are the independent and dependent variables, respectively. The constant term, or a, is the y-intercept.
Is a function 2x-5y=10 real? Is it nonlinear or linear?Given that a linear equation is an equation of a straight line, its degree must be either 0 or 1.
For every one of its elements. In this instance, both the degree of the variables Y and X is 1.
Resolve the Y equation.
2x-5y=10
Y=-2+2x/5
Hence Given that a linear equation is an equation of a straight line, its degree must be either 0 or 1. For every one of its elements. The degree of the variable Y in this instance is 1, while the degree of the variable X is linear at 1.

What is the length of one of the diagonals of the rectangle?
Enter an expression in the box for the length of the diagonal.
Answers
d(S,P) = √b^2
d(S,P) = b
so
SP = b
d(P, Q) = √(a-0)^2 + √(b-b)^2
d(P, Q) = √a^2
d(P, Q) = a
so
PQ = a
SQ = c^2 = a^2 + b^2
SQ = √(a^2 + b^2)
answer
the length of one of the diagonals of the rectangle is √(a^2 + b^2)
The length of a line with known end point coordinates is given by Pythagoras's theorem
The expression for the length of the diagonal [tex]\overline{PR}[/tex], is [tex]\underline{\sqrt{b^2 + a^2}}[/tex]
The expression for the length of the diagonal [tex]\overline{QS}[/tex], is [tex]\underline{\sqrt{b^2 + a^2}}[/tex]
Reason:
The given coordinates of the vertices are; P(0, b), Q(a, b), R(a, 0), and S(0, 0)
Diagonals of the rectangle are segments; [tex]\overline{PR}[/tex], and [tex]\overline{QS}[/tex]The lengths of the diagonals are given by the equation for finding the length, l, of a line given the coordinates which is [tex]l = \sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}[/tex]
Where:
(x₁, y₁) = P(0, b), and (x₂, y₂) = R(a, 0), we get;
[tex]Length \ of \ diagonal \ segment \ \overline{PR} = \sqrt{\left (0-b \right )^{2}+\left (a-0 \right )^{2}} = \sqrt{b^2 + a^2}[/tex]Where:

Chloe draws three parallelograms. In each figure, she measures a pair of angles, as shown.
What is a reasonable conjecture for Chloe to make by recognizing a pattern and using inductive reasoning?
In a parallelogram, all angles are congruent
In a parallelogram, consecutive angles are congruent.
In a parallelogram, consecutive angles are supplementary.
In a parallelogram, all angles are supplementary.
Answers
Solution-
1st statement- In a parallelogram, all angles are congruent.
If all the angels are congruent then all angles will be 90° (as summation of all the angles are 360° and 360/4= 90°), then it will be either a rectangle or a square, not a parallelogram.
2nd statement- In a parallelogram, consecutive angles are congruent.
If consecutive angles are congruent, then it will be rectangle or a square, not a parallelogram. In a parallelogram, opposite angles are congruent not consecutive angles.
4th statement- In a parallelogram, all angles are supplementary.
In a parallelogram, all the consecutive angles are supplementary or summation of measurements consecutive angles is 180°, not all the angels are supplementary, because opposite angles can't be supplementary.
3rd statement- In a parallelogram, consecutive angles are supplementary.
This is the reasonable conjecture for a parallelogram, because always the summation of measurement of consecutive angles are 180°.
