First order equations include linear equations. In the coordinate system, the linear equations are defined for lines. A linear equation in one variable is one in which there is a homogeneous variable of degree 1 (i.e., only one variable). Multiple variables may be present in a linear equation. Linear equations in two variables, for example, are used when a linear equation contains two variables. Examples of linear equations include 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, and 3x - y + z = 3.
In weekday = 10000
In weekend = 8000
There are 5 weekdays and 2 days in weekend
SO, 5 x 10000 + 2 x 8000
= 50000 + 16000
= 66000 steps.

Which expression is equivalent to (2^-1)^3
Answers
The solution is [tex]\frac{1}{8}[/tex] .
To understand this problem we need to know the concept of surds and indices, powers and exponents.
If we write [tex]x^{2}[/tex] it means that x must be multiplied by itself two times.
But if we write [tex]x^{-2}[/tex] it means [tex]\frac{1}{x^{2} }[/tex].
Which means if an number has negative power then it must be written in the inverse format to make it positive.
Given here is [tex](2^{-1})^{3}[/tex]
⇒[tex](\frac{1}{2}) ^{3}[/tex]
⇒[tex]\frac{1}{8}[/tex] is the required solution of the problem.
This can also be solved in other ways by multiplying the powers and then inverting the fraction to make it positive.

10. How many times smaller
is 0.98 than 9.8?
Answers
Explanation:
Since these number are in the decimal system, we know that as the decimal moves to the left, each digit it passes is divided by 10. As the decimal moves to the right, each digit it passes is multiplied by 10.
So in this example the decimal moves to the left one digit which means it divides by 10 so we go from 9.8 to 0.98.
Hence we say 0.98 is 10 times smaller than 9.8.

w is proportional to square root of y. y is inversely proportional to x. When x = 4, y = 16 and w = 8.
Find w in terms of x
Answers
The value of w in terms of x is w = 16/√x
VariationFrom the question, we are to find w in terms of x
From the given information,
w is proportional to square root of y
That is,
w ∝ √y
∴ w = k√y
Where k is the proportionality constant
and
y is inversely proportional to x
That is,
y ∝ 1/x
y = c/x
Where c is the constant of proportionality
From the information, we have that
When x = 4, y = 16 and w = 8
From w = k√y
8 = k√16
8 = k×4
k = 8/4
k = 2
Also,
y = c/x
16 = c/4
c = 16 × 4
c = 64
Now, we are to write w in terms of x
w = k√y and y = c/x
∴ w = k√(c/x)
w = 2√(64/x)
w = 2 × √64 / √x
w = 2 × 8/√x
w = 16/√x
Hence, the value of w in terms of x is w = 16/√x

Answers
63273600 license plates can be created using either three uppercase English letters preceded by three digits or four uppercase English letters tried to follow by two digits.
What are permutations and combinations?Permutations and combinations are the various ways in which objects from a set can be selected to form subsets, generally without replacement.When the order of selection is a factor, this selection of subsets is called a permutation; when it is not, it is called a combination.So,
Uppercase English letters equal 26.and the digits = 10 (0 to 9)Three uppercase English letters, then three digits:
First letter = 26 different waysSecond letter = 26 different waysThird letter = 26 different waysFourth digit = 10 different waysFifth digit = 10 different waysSixth digit = 10 different waysTotal number of possible ways = 26 x 26 x 26 x 10 x 10 x 10 = 17576000
Four uppercase English letters, then two digits:
First letter = 26 waysSecond letter = 26 waysThird letter = 26 waysFourth letter = 26 waysFifth digit = 10 waysSixth digit = 10 waysTotal number of possible ways = 26 x 26 x 26 x 26 x 10 x 10 = 45697600
Three uppercase English letters, three digits, or four uppercase English letters, two digits.
= three uppercase English letters, three digits + four uppercase English letters, two digits= 17576000 + 45697600= 63273600Therefore, 63273600 license plates can be created using either three uppercase English letters preceded by three digits or four uppercase English letters tried to follow by two digits.

Given data
The two triangle that has the values are attached:
How to find the value of x, y, and z to make the triangles congruentThe value of x
( 2x + 6 ) mm = 36 mm
2x mm = ( 36 - 6 ) mm
2x mm = 30 mm
x = 30 / 2 mm
x = 15 mm
The value of y
( 6y ) mm = 36 mm
y = 36 / 6 mm
y = 6 mm

The line y=x+1 intersects the graph of y=x^2-3x-11 at the points A and B
Find the coordinates of A and B
Answers
Answer:
(6, 7) and (-2, -1)
Step-by-step explanation:
if y=x+1 intersects with y=x^2-3x-11
then we need to find x and y such that both of those equations are true.
If y = x + 1 is true and y=x^2-3x-11, then
y - y = x^2-3x-11 - x - 1 is also true
0 = x^2 - 4x - 12
use your preferred method to solve the quadratic equation
0 = (x - 6)(x + 2)
x = 6 or x = -2
now for each x we take y from either equation, but y = x + 1 is simpler.
for x = 6 the coordinates are (6, 7) and for x = -2 the coordinates are (-2, -1)

Using some logarithmic properties, we will see that the solution of the logarithmic equation is 10.5
How to find the value of the logarithm?
Here we have some properties that you need to remember.
log(A*B) = log(A) + log(B)
log(A/B) = log(A) - log(B)
log(Aⁿ) = n*log(A)
Then we can rewrite our equation as:
[log(x²) + log(√z)] - log(y³)
Now, remember that a square root is equal to an exponent of 0.5, then:
[log(x²) + log(√z)] - log(y³) = 2*log(x) + 0.5*log(z) - 3*log(y)
Now we can replace the logarithms by the given values:
2*log(x) + 0.5*log(z) - 3*log(y)
2*7 + 0.5*5 - 3*2 = 10.5
The solution of the logarithmic equation is 10.5

One of the solutions to the following linear inequality is the value x=-10.
What are linear inequalities?
Expressions that compare two linear expressions using inequality symbols are referred to as linear inequalities. It's important to remember that if p < q, then p must be a number that is strictly less than q. If p ≤ q, then p is a number that is strictly smaller than q or exactly equal to q. The same is true for the other two inequality signs > (greater than) and ≥ (greater than or equal to).
What guidelines apply for resolving linear inequalities?
Addition Rule of Linear Inequalities:If a > b, then a + x > b + x and if a < b, then a + x < b + x.Subtraction Rule of Linear Inequalities:
If a > b, then a − x > b − x and if a < b, then a − x < b − x.Multiplication Rule of Linear Inequalities:
If a > b and a > 0, then a * x > b * x and if a < b and a > 0, then a * x < b * x,
If a > b and a < 0, then a * x < b * x and if a < b and a < 0, then a * x > b * x.Division Rule of Linear Inequalities:
If a > b and a > 0, then (a/x) > (b/x) and if a < b and a > 0, then (a/x) < (b/x).
If a > b and a < 0, then (a/x) < (b/x) and if a < b and a < 0, then (a/x) > (b/x)

Answers
Answer: Equation using slope intercept from y= -(5/2)x +26
Step-by-step explanation:
Write an equation of the line (in slope-intercept form) that is perpendicular to the line y=(2/5)x-(1/5) and contains the point (-4,16).
The line given is y=(2/5)x-(1/5)
Which we can rewrite in y= mx+b form as
y=(2/5)x-(1/5)
So slope of this line is (2/5)
A line perpendicular will have slope = -(5/2) , Which is (1/m)
Equation of new line will be
y = -(5/2)x +b
Now we need to find b
Plug in Point (-4,16)
Replace with the (-4,16) values
16 = (5/2) (-4) +b
solve it, 16=(-10)+b
