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.

Find g(x)-f(x) if f(x)=-3+4 and g(x)=5x-12

Verizon [17]

Answer: g(x)-f(x)=8x-16

Explanation:

f(x)=-3x+4 (I am assuming "-3+4" is a typo and it is "-3x+4")

g(x)=5x-12

g(x)-f(x)=(5x-12)-(-3x+4)=5x+3x-12-4=8x-16

Mike can stitch 7 shirts in 42 hours. he can stitch 1 shirt in how many hours, and in 1 hour he can stitch how much of a shirt.

podryga [215]

Answer:

Mike can stitch one shirt in 6 hours and in 1 hour he can stitch $\frac{1}{6}$ (0.167) shirts.

Step-by-step explanation:

Mike can stitch 7 shirts in 42 hours

to calculate the time that he takes to make 1 shirt, we have to divide 42 by 7.

He can stitch 1 shirt in = $\frac{42}{7}$ = 6 hours

Now we calculate the work done in one hour.

He can stitch in 1 hour = $\frac{1}{6}$ shirts or 0.167 shirts

Mike can stitch one shirt in 6 hours and in 1 hour he can stitch $\frac{1}{6}$ shirts.
