When a matrix is multiplied by a constant, the constant multiplies each of the elements of the matrix.

2\left[\begin{array}{cc}4&0\\-1&5\end{array}\right]=\left[\begin{array}{cc}2\cdot 4&2\cdot 0\\2\cdot(-1)&2\cdot 5\end{array}\right]\\\\=\left[\begin{array}{cc}8&0\\-2&10\end{array}\right]

Solve using any method. −2x+y=−3 x+y=3 ( 5, 2) ( 1, 2) ( 2, 5) ( 2, 1)
nignag [31]

Answer:

Therefore the solution set is (x , y) = ( 2 , 1 )

Step-by-step explanation:

Given:

-2x+y=-3  ...............Equation ( 1 )

x+y=3\\  ...............Equation ( 2 )

\therefore y=3-x     ...............Equation ( 3 )

To Find:

x = ?

y = ?

Solution:

Using Substitution Method we will have

Substitute  above ' y ' Equation 3 in Equation 1 we get

-2x+(3-x)=-3\\-2x-x=-3-3\\-3x=-6\\3x=6\\x=\dfrac{6}{3}=2\\\\x=2

Now Substitute  ' x ' in Equation 3 we get

y=3-2=1\\y=1

Therefore the solution set is (x , y) = ( 2 , 1 )

F
Olegator [25]

Answer:

21

Step-by-step explanation:

If x was more than 1, then it would be impossible because fx would have to be even, but 4x+3 would be odd. Therefore, x must equal 1, and f must equal 7. This means that 3f=21

A bucket of paint has spilled on a tile floor. The paint flow can be expressed with the function p(t) = 5t, where t represents t
Rainbow [258]
Because we know the area in terms of paint flow, and paint flow in terms of time, we can substitute p(t) for p in the A(p) equation.

A(p(t)) = A(t) = <span>π * (5t)^2 (assuming it's squared for the A(p).
B: 314 units^2

If A(p) = </span>πp2 (instead of p^2), then A(t) = 10πt
B: 31.4 units^2
