The equation in the form of slope-intercept for Macario's hourly wage is y=9x+0.12s
What is a slope-intercept function?
A slope-intercept equation comprises the total amount paid as wages to Macario which includes the hourly rate of $9 multiplied by the number of hours spent working plus the 12% of total sales achieved by Macario, in essence, if we assume that the number of hours spent working is x and that total sale is s, the slope-intercept form that represents Macario's hourly wage y is shown thus:
y=9x+0.12s

Moya is moving to a new house and packing up. She has 70 kilograms of books and 127 kg kilograms of clothing to send through the postal service. How much more do her clothes weigh than her books? How much is her shipping cost of she has to pay $80 per kg of books and $200 per kg of clothing?
The difference in her clothes and her books will be 57kg.
The difference in shipping cost if she has to pay $80 per kg of books and $200 per kg of clothing will be $19800.
How to calculate the value?From the information, Maya has 70 kilograms of books and 127 kg kilograms of clothing to send through the postal service, the difference in her clothes and her books will be:
= Weight of clothes - Weight of books
= 127 kg - 70 kg
= 57 kg
The difference in shipping cost if she has to pay $80 per kg of books and $200 per kg of clothing will be:
= 127(200) - 70(80)
= 25400 - 5600
= $19800

Solve the system of equations using a matrix

a+b=0
The solutions of a and b are 0 and 0 respectively using matrix.
Solving a system of linear equations using the inversion method involves two new matrices.Matrix A: representing variables Matrix B: represents a constant The system of equations can be solved by matrix multiplication which is given by [tex]X=A^{-1}B[/tex] ...(1)
We have given two equations 3a + 5b = 0 and a+b = 0
This can be written as AX=B
Where [tex]A=\left[\begin{array}{ccc}3&5\\1&1\\\end{array}\right][/tex] and [tex]X=\left[\begin{array}{ccc}a\\b\\\end{array}\right][/tex] , [tex]B=\left[\begin{array}{ccc}0\\0\\\end{array}\right][/tex]
A is the coefficient matrix, X the variable matrix and B the constant matrix.
[tex]|A|=3(1)-5(1)\\|A|=3-5=-2[/tex]
Since [tex]|A|\neq 0[/tex]
Hence, the system of equations is consistent and has a unique solution given
A inverse is given by [tex]A^{-1}=\frac{adjA}{|A|}[/tex] ....(2) and adj(A) is given by [tex]adjA=C^T[/tex]
[tex]M_{11}=1\\M_{12}=1\\M_{21}=5\\M_{22}=3[/tex]
Then Co -factors will be

Matrix C is represented by
[tex]C=\left[\begin{array}{ccc}1&-1\\-5&3\\\end{array}\right] \\\\C^T=\left[\begin{array}{ccc}1&-5\\-1&3\\\end{array}\right][/tex]
Putting |A| = -2 and transpose of C in equation (2) , we get
[tex]A^{-1}=\frac{1}{-2} \left[\begin{array}{ccc}1&-5\\-1&3\\\end{array}\right][/tex]
Putting the value of A inverse in equation (1) , we get

Each pair of values is from an inverse variation. Find the missing value. (2,5),(4, y)
The missing value of inverse variation is 2.5
What is Inverse variation ?The inverse variation property states that , whenever the product of values of two quantities is a constant value then there is opposite variation between these two corresponding values. Or we can also say that if the productive nature of two corresponding values is constant, then one quantity is inversely varies with second quantity.
Let say if x and y are two values and k is a constant value, then
According to inverse variation
k = xy or y = k/x
In the given question,
Take the order pair (2,5)
As it is an inverse variation, we can substitute it
y=k/x
5=k/2
K=10
Now find the inverse variation equation
y=k/x
Also, k=10
Solve this equation for the second pair (4,y)
As, y=k/x
y = 10/4 = 5/2 = 2.5
Therefore, missing value is 2.5

Step-by-step explanation:
1. first we have to get the denominator the same, so we multiply by [tex]\sqrt{x-1[/tex] to the first fraction top and bottom which leaves as with
3(x-1)/2[tex]\sqrt{x-1[/tex] - 3/2[tex]\sqrt{x-1[/tex]
- we can expand the numerator of the first fraction which becomes

They are about same distance from sea level.
Sean is exploring a coral reel below level= 91 feet
Liz is hiking above sea level= 91 feet
When, we compare both distance from sea level, both have the sane distance. Although, the distance between both Sean and Liz is 91+91= 182 feet.
When compare the level of both , both are at 91 feet one is below the sea level and another is above the sea level. Hence, both are at the same distance from the sea level.

How does exponential growth utilise e?
e is the constant growth rate that all processes that are growing continuously share. With e, you may compare a simple growth rate—where all change occurs at the end of the year—with a compound, continuous growth rate, where growth occurs once per nanosecond or quicker.Let the principle sum be P
Let the number of years be n
Thus the total sum for n years is

Find the inverse of each function. Determine whether each inverse is a function. f(x)=√x+6
The inverse of the function f(x)=√x+6 will be x²-12x+36.
Inverse function-A function that can reverse into another function is known as an inverse function or anti-function.
The given function is,
f(x)=√x+6
As we know inverse of the function is shown as,
y = f(x)
y=√x+6
For inverse function, we have to replace the variable's place value,
x=√y+6
√y=x-6
Squaring both sides,
(√y)²=(x-6)²
y=x²+36-12x
Hence,the inverse of the function f(x)=√x+6 will be x²-12x+36.

the height of a triangle is twice its base the area is 144cm³ find the base
Answer:
Base = 12cm
Height = 24cm
Step-by-step explanation:
Hello glittersplanet,
The formula for the area of a triangle is A = 1/2 b * h where A equals the area, b equals the base, and h equals the height. You are given the area in this problem.
Let the following conditions apply:
Base = x
Height 2x <-------Problem states the height is twice its base, correct?
Therefore:
A = 1/2 b*h
144 = 1/2 (x)(2x)
Simplify by removing the fraction by multiplying through by 1/2 and you are left with x^2 correct? Therefore:
144 = x^2
x = √144
x = 12
Therefore, base = x = 12 while height = 2x = 2(12) = 24
x = √144
Footing-x=12
Height-x2=24

The unknow angle of the triangle is as follows:
m∠C = 46.2°
How to find the angle of a triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
In simpler term, a triangle is a kind of polygon that 3 sides and 3 angles.
Therefore, the sum of angles in a triangle is equals to 180 degrees.
Hence, the sum of angles in ΔABC is 180 degrees.
Therefore,
m∠A + m∠B + m∠C = 180°
m∠A = 32.1°
m∠B = 101.7°
m∠C = x
32.1 + 101.7 + x = 180
x + 133.8 = 180
x = 180 - 133.8
x = 46.2 degrees.
