Using Cramer’s Rule, what is the value of x in the system of linear equations below?

cluponka [151]

Answer:

x = 8 is the answer

Step-by-step explanation:

In order to find the solution of Equations using Cramer's rule

we shall find matrices

D= $\left[\begin{array}{ccc}5&-3\\1&-2\end{array}\right]$ =

$D_{1} = \left[\begin{array}{ccc}4&-3\\-16&-2\end{array}\right]$

l D l = Determinant formed by coefficient of variables

Here l D l = 5X(-2) - 1X(-3)= -10+3 = -7

l D1 l = Determinant formed by replacing first column In D by numbers on the right side of the equations

Here l D1 l = 4X(-2)- (-16)X(-3)= -8-48 = -56

here x is given by $\frac{l D1 l}{l D l}$

x = $\frac{-56}{-7}$

x = 8

How do I use intercepts to graph 3y= - 5x - 30

expeople1 [14]

Answer:

y-intercept is (0,-10) and x-intercept is (-6,0). Connect them by a straight line to graph the given equation.

Step-by-step explanation:

The given equation of line is

$3y=-5x-30$

For x=0,

$3y=-5(0)-30$

$3y=-30$

$y=-10$

So, y-intercept is at point (0,-10).

For y=0,

$3(0)=-5x-30$

$0=-5x-30$

$5x=-30$

$x=-6$

So, x-intercept is at point (-6,0).

Now, plot the point (0,-10) and (-6,0) on a coordinate plane and connect them by a straight line to graph the given line as shown below.

Which expression is not equal to1/4 of 52

Art [367]

1/4 as a decimal is 0.25 (divide one by four). You can also multiply 1/4 by 52, but converting it into a decimal is typically easier.

"Of" typically means multiply, so multiply 52 * 0.25 to get the product 13.

For Option A., solve for 0.25 * 52, the final result should be 13.

For Option B., convert 4% into a decimal by dividing 4 over 100, you will get 0.04, multiply 0.04 * 52 to get 2.08.

For Option C., divide 52 by 4, the quotient should be 13.

For Option D., 52 over 4 is another way to write 52 divided by 4, therefore, the answer, once again, is 13.

When comparing all the answers, you will notice all the answers are equal, except option B.

2.08 is not equal to 13

Therefore, your answer is B. 4% of 52
