Answer:
1 meter to centimeters: 1 meter x 100
1 meter to kilometers: 1 meter ÷ 1,000
Step-by-step explanation:
There are 100 cm and 0.001 km in one meter.
What is a Ratio?A ratio indicates the number of times one number contains another.
There are 100 cm in one meter and 1000 meters in one kilometer, therefore,
1 meter = 100 cm
1 meter = 0.001 km
Hence, there are 100 cm and 0.001 km in one meter.

Which equation is non-linear?
A) [tex]y=3x^3-10[/tex]
B) [tex]y=1/2x+4[/tex]
C) [tex]y=4x-5/3[/tex]
D) [tex]-3x--7y=-21[/tex]
Answer:
[tex]\huge\boxed{\text{A is not linear.}}[/tex]
Step-by-step explanation:
Linear equations are equations that, when graphed, form a "line" and have a constant rate of change.
Usually, these are in the form [tex]y=mx+b[/tex] when put in that order.
There are a few types of equations, I'll list some of the major ones
Linear = has a constant rate of changeExponential = increases for x as the exponent Quadratic = is in a binomial, trinomial, or polynomial - it has a vertex
Linear functions are usually in the form [tex]y=mx+b[/tex]
Exponential functions are usually in the form [tex]y=b^x[/tex]
Quadratic functions are usually in the form [tex]ax^2 + bx + c[/tex]
We must note that linear functions can not
A) Have an exponent on any x term
B) Have x and y multiplied by each other
We can see that every equation, except A
A) Follows the form [tex]y=mx+b[/tex] ([tex]-3x--7y=-21[/tex] can be simplified to [tex]y= \frac{3}{7}x-3[/tex])
B) Does not have any exponents on their x terms
That leaves A) to be the equation that isn't linear.
Hope this helped!
Answer:
Equation A is non-linear.
Step-by-step explanation:
We are given four equations in which we need to determine if they are linear or non-linear relationships.
Firstly, we need to know some information about linear equations:
Linear equations cannot have an exponent.Linear equations have a constant slope and are straight lines.Linear equations can be negative or positive.Linear equations have a domain of all real numbers. They also have a range of all real numbers.Now, in order to check this easily, we need to place these equations into slope-intercept form.
Equation A
[tex]\displaystyle y = 3x^3 - 10[/tex]
We see that this has an exponent, so this cannot be a linear equation.
In fact, because it is cubed, this is called a cubic function. Therefore, equation A is not a linear equation.
Equation B
[tex]\displaystyle y = \frac{1}{2}x + 4[/tex]
This equation does not have a exponent. It also has a slope and a y-intercept. Therefore, equation B is a linear equation.
Equation C
[tex]\displaystyle y = 4x -\frac{5}{3}[/tex]
The equation does not have a exponent. It also has a slope and a y-intercept. Therefore, equation C is a linear equation.
Equation D
[tex]-3x--7y = -21[/tex]
First off, we need to get this equation into slope-intercept form, if possible.
[tex]\displaystyle -3x -- 7y = -21\\\\-3x + 7y = -21 \ \ \ \text{Change the sign on 7y.}\\\\7y = 3x - 21 \ \ \ \text{Move 3x to the other side by adding.}\\\\\frac{7y}{7}=\frac{3x-21}{7} \ \ \ \text{Divide both sides by 7 to isolate y.}\\\\\bold{y = \frac{3}{7}x-3}[/tex]
Our final equation is [tex]\displaystyle y = \frac{3}{7}x-3[/tex].
The equation does not have an exponent. It has a constant slope and a y-intercept. Therefore, equation D is a linear equation.
Let's check our equations:
Equation A: [tex]\displaystyle y = 3x^3 - 10 \ \text{X}[/tex]Equation B: [tex]\displaystyle y = \frac{1}{2}x + 4 \ \checkmark[/tex]Equation C: [tex]\displaystyle y = 4x -\frac{5}{3} \ \checkmark[/tex]Equation D: [tex]\displaystyle y = \frac{3}{7}x-3 \ \checkmark[/tex]Therefore, we have determined that Equation A is not a linear equation, making it non-linear.

At what point does the graph of 3x + 4y = 15 intersect the graph of x^2 + y^2 = 9? Express any non-integer coordinate as a common fraction.
Answer
12 and 36 and 13
If you need an explanation;
let's first isolate x in 3x + 4y = 15 ---
x = (15 - 4y) / 3
now substitute as x in the second equation provided ---
((15 - 4y) / 3)^2) + y^2 = 9,
((15 - 4y) / 3)^2) +( 3y/3)^2 = 9,
((15 - 4y)^2 + (3y/3)^2)/3^2 = 9,
225 - 120y +25y^2/9 = 9,
225 - 120y +25y^2 = 81,
25y^2 - 120y + 144 = 0
we now solve using the quadratic formula ---
[tex]y_{1,\:2}=\frac{-\left(-120\right)\pm \sqrt{\left(-120\right)^2-4\cdot \:25\cdot \:144}}{2\cdot \:25}\\=\frac{-\left(-120\right)\pm \sqrt{0}}{2\cdot \:25}\\=\frac{-\left(-120\right)\pm \sqrt{0}}{2\cdot \:25}\\\\= 12/5[/tex]
So then x = (15 - 4*12/5)/3 = 9/5. Our solution = (9/5, 12/5)

In the diagram below, line AB is parallel to line CD. The measure of
∠∠ABC is 28° and the measure of ∠∠EDC is 42°. Find the measure of∠∠CED. Explain why you are correct by presenting an informal argument that uses the angle sum of a triangle.
what is the measure of ∠∠CED is ? And Explain why ?
Answer:
ced is 110 degrees
Step-by-step explanation:
because ECD is 28 degrees and 28+42=70 and a triange always = 180 degrees so it would have to be 110
The measure of ∠CED is 110 degrees by angle sum property of the triangle.
We are given that line AB is parallel to line CD.
The measure of ∠ABC is 28° and the measure of ∠EDC is 42°
What are exterior angles?An exterior angle is a measure of rotation between one extended side(we extend it virtually) of the polygon with its adjacent side which is not extended.
We know that line AB is parallel to line CD.
So according to alternate interior angles measure of ∠ABC is 28° will be equal to BCD.
Thus, Angle BCD= 28 degrees
Hence, in a triangle CED
∠CED + ∠EDC + BCD = 180
∠CED + 28 + 42 = 180
∠CED = 180 - 70
∠CED = 110 degrees
Therefore, the measure of ∠CED is 110 degrees by angle sum property of the triangle.

Jessica is 5 years older than her sister Jenna. Jenna tells her sister that in 5 years, she will be as old as Jessica was 5 years ago. If Jenna’s age is x, which equation represents the situation? How many solutions does the equation have?
A.
x + 5 = (5 − x) − 5, which has one solution
B.
x + 5 = (x + 5) − 5, which has infinitely many solutions
C.
x + 5 = (x + 5) − 5, which has no solution
D.
x + 5 = (5 − x) − 5, which has infinitely many solutions
E.
Answer:
Jenna's age Jessica's age
today x x + 5
in 5 years x+5
5 years ago x + 5 - 5
Equality x + 5 = x + 5 - 5
=> x + 5 = x
The equation is x + 5 = x
That equation has not any solution, because it reduces to 5 = 0, which is an absurd.
So, the conclusion is that information given by Jenna is wrong.
It is logical: if the difference of the ages is 5, in five years Jenna will have 10 years more than what her sister had 5 years ago, no 5 as she told Jessica.
Answer:
(x + 5) + 5 = (x + 5) + 5, which has infinitely many solutions
