Its forcing me to do this for some reason i just wamt to use the website bro

type the slope intercept equation of the line that passes through the point (1,1)&(7,4) enter fraction in simplest form

9966 [12]

$\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
&({{ 1}}\quad ,&{{ 1}})\quad 
% (c,d)
&({{ 7}}\quad ,&{{ 4}})
\end{array}
\\\\\\
% slope = m
slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{4-1}{7-1}\implies \cfrac{3}{6}\implies \cfrac{1}{2}$

$\bf y-{{ y_1}}={{ m}}(x-{{ x_1}})\implies y-1=\cfrac{1}{2}(x-1)\\
\left. \qquad \right. \uparrow\\
\textit{point-slope form}
\\\\\\
y-1=\cfrac{1}{2}x-\cfrac{1}{2}\implies y=\cfrac{1}{2}x-\cfrac{1}{2}+1\implies y=\cfrac{1}{2}x+\cfrac{1}{2}$

A manufacturer makes two type if products X and z at each if two different locations A and B. the materials used to make each if

Snezhnost [94]

Using matrix algebra, the material cost of making one of each product at each location is as follows:

<h3 />

Product X Product Z

Location A birr 38 birr 50

Location B birr 38 birr 49.5

<h3>What is matrix algebra?</h3>

Matrix algebra involves the arrangement of numbers in a rectangular array.

Matrices are arranged in columns and rows to express some mathematical values.

<h3>Data and Calculations:</h3><h3>Matrix O: Materials Requirement Per Unit</h3>

Steel Glass Plastic

Product X 3 1 2

Product Z 4 0.5 3

<h3>Matrix P: Materials Cost Per Unit</h3>

Steel Glass Plastic

Location A 10 2 3

Location B 9 3 4

<h3>Matrix R: (O x P) Material Cost of Product X</h3>

Steel Glass Plastic Total

Location A 30 2 6 38

Location B 27 3 8 38

<h3>Matrix R: (O x P) Material Cost of Product Z</h3>

Steel Glass Plastic Total

Location A 40 1 9 50

Location B 36 1.5 12 49.5

Thus, Product X costs birr 38 at locations A and B, respectively, while Product Z costs birr 50 and birr 49.5 at locations A and B, respectively.

Kendra charges $11 to shovel a driveway. She shoveled 4 driveways on Saturday and then some more on Sunday. She made $143 for th

olya-2409 [2.1K]

For this case, the first thing we must do is define a variable.
We have then:
x: amount of driveways shoveled on Sunday
y: total amount
We now write the equation that models the problem:
$y = 11x + 44
$
She made $ 143 for the weekend:
$143 = 11x + 44
$
From here, we clear the value of x:
$11x = 143 - 44

x = 99/11

x = 9$
Answer:
She shoveled 9 driveways on Sunday
