Answer: [tex]y=\frac{1}{9}x[/tex]
Step-by-step explanation:
Perpendicular lines have negative reciprocal slopes, so the slope of the line we want to find is 1/9.
Since the y-intercept is 0, the equation is [tex]y=\frac{1}{9}x[/tex].

Kim and jake are competing in the big race. jake starts at the starting line and rides at 2 meters per second. kim gets a 6 meter head start and rides at 3 meters every 2 seconds. write an equation for kim and jake
The equation obtained for Kim will be t = x/2
Equation obtained for Jake will be t = (x - 6)/1.5
As for the problem, Kim and Jake are competing in the big race. And the values of their speed are given below.
Kim moves at a 2-meter-per-second running pace.
Jake moves at a 1.5 meter per second running pace (3 meters per 2 seconds)
Jake gets 6 meters ahead of Kim.
To get equations for the same case to both persons we should get it as,
Let x be the complete race distance and t be either Kim's or Jake's total race time.
Time = Speed/Distance
Kim's time equation is t = x/ 2.
The time equation that Jake uses is t = (x - 6)/1.5.

enry can write 5 pages of his novel in 3 hours. At this rate, how many pages can Henry write in 8 hours?
Henry can write 13 pages in 8 hours, at this rate.
This is a problem from the unitary method. We can solve this question following a few steps.
Here if Henry can write 5 pages of his novel in 3 hours. We have to find the number of pages that Henry can write within 1 hour.
The number of pages Henry can write within 1 hour is 5/3 pages.
[Number of pages within a unit hour = number of total pages/ total hour]
Therefore, Henry writes in 8 hours is, ( 5/3 × 8 ) = 40/3 = 13.33 ≈ 13 pages

X _-2, -1, 1, 2Y_ -9, -5, 3,7find the equation that represents the table
Answer:
E. 4x - 1
Explanation:
An equation that represents the table satisfies that when we replace each value of x in the table, we get its respective value of y in the table.
So, the answer is:
y = 4x - 1
Because:
For x = -2, we get:
y = 4(-2) - 1
y = -8 - 1
y = -9
For x = -1, we get:
y = 4(-1) - 1
y = -4 - 1
y = -5
For x = 1:
y = 4(1) - 1
y = 4 - 1
y = 3
For x = 2:
y = 4(2) - 1
y = 8 - 1
y = 7

the square will fit inside the circle without

9 cm
5 cm
Since the diagonal is less than the circle's diameter, the Pythagorean theorem reveals that the square may fit within the circle without touching its edge.
How to use the Pythagorean theorem to determine if a square fits within a circle or notSince squares are made up of two right triangles of equal length, the Pythagorean theorem is used to calculate the length of the hypotenuse of right triangles, which corresponds to the diagonals in squares.
The diagonal (L) of the square must be less than the diameter of the circle if it can fit within the circle without touching the edge (d). Therefore, we continue to establish this connection:
[tex]L=\sqrt{2}.5cm[/tex]
L ≈ 7.071 cm

What is Arithmetic Progression (AP)?
The difference between any two consecutive integers in an arithmetic progression (AP) sequence of numbers is always the same amount.For instance, the sequence 2, 6, 10, 14,... is an arithmetic progression (AP) because it adheres to the rule that each number is obtained by adding 4 to the term before it. The nth term in this series equals 4n-2. You can determine the terms of the series by changing the nth term to n=1,2,3,...16, 48, 80, ?
Use The sum up to nth terms of an AP is given as :-
S(n) = (n/2)[2a + (n - 1)d]
In this arithmetic sequence, each term is 32 more than the one immediately before it.

Solve the system of equations by elimination

What is an equation?
An equation is a formula in mathematics that expresses the equivalence of two expressions by linking them with the equals symbol =. The word equation and its cognates in various languages may have somewhat different definitions; for example, in French, an équation is defined as including one or more variables, but in English, an equation is any well-formed formula consisting of two expressions linked by an equals sign. An equation consists of two expressions joined by an equals sign ("="). The expressions on each side of the equals sign are referred to as the equation's "left-hand side" and "right-hand side." The right-hand side of an equation is frequently considered to be zero.
4x - 2y = 6....................equation (1)
-2x + 4y = -24...............equation (2)
Multiply equation (1) by 2 and add with equation (2)
8x - 4y = 12
-2x + 4y = -24
----------------------
6x = -12
or, x = -12/6 = -2
from equation (1),
4x - 2y = 6
or, 4(-2) - 2y = 6
or, -2y = 6 + 8
or, y = 14/-2 = -7
Hence, from the equations we get 'x' as '-2' and 'y' as '-7'

What is equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. We have LHS = RHS (left hand side = right hand side) in every mathematical equation. To determine the value of an unknown variable that represents an unknown quantity, equations can be solved. A statement is not an equation if it has no "equal to" sign.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" symbol and terms on both sides must always be present when writing an equation.
Given equation:
y=2x-1 .....(1)
y=x+5....(2)
Now solving equation 1 and 2, we get
2x -1 = x + 5
2x - x= 5 +1
