This is the graph for both 1/2x+3 and 4x-8y=-24
4x-8y=-24 in to slope intercept form is 1/2x+3
1/2x+3 into standard form is 4x-8y=-24
They are the same equation written in different forms

Help with matrices please? Any wrong/not applicable answers will be reported and BLOCKED

m x H = $\left[\begin{array}{ccc}-25&37.5&-12.5\\\9\end{array}\right]$

Step-by-step explanation:

Step 1; Multiply 5 with this matrix $\left[\begin{array}{ccc}-1&2\\4&8\\\end{array}\right]$ and we get a matrix $\left[\begin{array}{ccc}-5&10\\20&40\\\end{array}\right]$

Multiply the fraction $\frac{2}{5}$ with the matrix $\left[\begin{array}{ccc}-1&2\\4&8\\\end{array}\right]$ and we get $\left[\begin{array}{ccc}-\frac{2m}{5} &\frac{4m}{5} \\\frac{8m}{5} &\frac{16m}{5} \\\end{array}\right]$

Step2; Now equate corresponding values of the matrices with each other.

-5 = $\frac{-2m}{5}$ and so on. By equating we get the value of m as $\frac{25}{2}$

Step 3; Add the matrices to get the value of matrix m.

Adding the three matrices on the RHS we get $\left[\begin{array}{ccc}2&9&-9\\\end{array}\right]$ .

Step 4; Adding the matrices on the LHS we get the resulting matrix as H +

$\left[\begin{array}{ccc}4&6&-8\\\9\end{array}\right]$ . Equating the matrices from step 3 and 4 we get the value of H as $\left[\begin{array}{ccc}-2&3&-1\\\9\end{array}\right]$

Step 5; Now to find the value of m x H we need to multiply the value of $\frac{25}{2}$ with the matrix $\left[\begin{array}{ccc}-2&3&-1\\\9\end{array}\right]$

Step 6; Multiplying we get the matrix m x H = [ -25 $\frac{75}{2}$ $\frac{-25}{2}$ ]

7. A study reported that in a random sampling of 100 women over the age of 35 showed that 8 of the women were married 2 or more

Pavel [41]

Hi! The answer is going for be D (400)

Step-by-step explanation:

Out of 100 women, 8 were married 2 or more times which is 8% or 0.08

So out of 5000 women, the number of women married 2 or more times is: 0.08*5000 = 400

x/5000 = 8/100

x/50=8/1

x=400

Hope this helps! Have a good day!
