For a 2x2 matrix, the determinant is the absolute value of ad-bc
in this case, a=4, b=-7, c=3, d=-2
4*(-2)=-8
-7*3=-21
-8-(-21)=13
so the answer is D

The graph of f(x) = 2x is shown on the grid. The graph of g(x) = ()x is the graph of f(x) = 2x reflected over the y-axis. Which
lakkis [162]

Answer:

While the graph is not shown, it would be the graph of g(x) = -2x.

Step-by-step explanation:

A reflection across the y-axis negates the x-coordinate of every point.  To find the function associated with this, we would replace x with -x:

g(x) = f(-x) = 2(-x) = -2x

The function would be g(x) = -2x.

Who can solve this exercises pleaseeee i have a exam
Leona [35]

Answer:

Step-by-step explanation:

1) Two angles supplementary. So sum of two angles is 180

One angle  = x

Other angle = 2x

x + 2x = 180

3x = 180

x = 180/3 = 60

The angles are 60, 120

2)Two angles complementary. So sum of two angles is 90

one angle  = x

Other angle = x + 20

x +x +20 = 90

2x + 20 = 90

2x = 90- 20

2x = 70

x = 70/2 = 35

The angles are 35,55

3) one angle =x

Other angle = 3x - 20

x + 3x - 20 = 120

4x = 120 + 20

4x = 140

x = 140/4 = 35

The angles are 35,85

5) x + 4x -20 = 180

5x = 180 + 20

5x = 200

x = 200/5 = 40

x = 40

6) This sum is not clear only half is visible

How do you write an equation to represent a real-world situation?
Maurinko [17]
You have to organize the parameters of the real-world situation that is known and unknown. Also, you have to distinguish which of them are dependent and independent. Next, you assign letters as your variables. Lastly, you make an algebraic expression by translating the relationship into the mathematics.
