Answer:

hi! you have 2 points! this means slope formula! y2-y1/x2-x1

okay all you do now is plugin! (x1 1,y1 3) (x2 3,y2 7) what I did was label your x1 y1 x2 y2! now just follow the formula and that / is division or basically a fraction

7-3/3-1

that equals -5! and that's your slope! memorize the formula it helpss!

Determine the value(s) of h such that the matrix is the augmented matrix of a consistent linear system. [Start 2 By 3 Matrix 1s

Leni [432]

Answer: h = 9

Step-by-step explanation: A system of linear equations is consistent when it has at least one solution.

The matrix given is:

$\left[\begin{array}{ccc}-15&21&h\\5&-7&-3\end{array}\right]$

Transform this matrix in a row-echelon form:

$\left[\begin{array}{ccc}-15&21&h\\5&-7&-3\end{array}\right]$ $R_{2} = 3R_{2}+R_{1}$ $\left[\begin{array}{ccc}-15&21&h\\0&0&-9+h\end{array}\right]$

For this row-echelon form to have solutions:

-9 + h = 0

h = 9

For this system to be consistent: h = 9.

What value of a makes the equation true? 1.7a+0.3a=4/5 A) a=2/5 B) a=−1 1/5 C) a=2 4/5 D) a=1 3/5

7nadin3 [17]

First you want to collect the like terms, 2a=45 , then divide both sides of the equation by 2 which is a=2/5 , or a=0.4
