antiseptic1488 [7]

Answer:

-2

Step-by-step explanation:

g(3)= 2(3)-7

g(3)= 6-7

g(3)= -1

f(g(3))= 4(-1)+2

f(g(3))= -4+2

f(g(3))= -2

A math class is having a discussion on how to determine if the expressions 4x-x+5 and 8-3x-3 are equivalent using
Mkey [24]

Answer:

  Both expressions should be evaluated with two different values. If for each substituted value, the final values of the expressions are the same, then the two expressions must be equivalent.

Step-by-step explanation:

Both expressions are linear expressions. It takes 2 points to define a line. If the lines defined by each expression go through the same two points, then the expressions are equivalent.

If the expressions have the same value for two different variable values, they are equivalent. (choice D)

_____

<em>Additional comment</em>

One more point is needed than the degree of the polynomial expression. That is, quadratic (degree 2) expressions will be equivalent if they go through the same 2+1 = 3 points.

The measures of two supplementary angles are (4x + 8) and (6x + 3)º.
Illusion [34]

Step-by-step explanation:

A supplementary angle is an angle that is 180 degrees. We are given two angles that add up to 180, but we need to solve for x first.

The first step is to solve both angles. We know that both angles added together are supplementary, so they are equal to 180.

4x + 8 = unknown angle

6x + 3 = unknown angle

(4x + 8) + (6x + 3) = 180

Because we know a supplementary angle is 180 degrees, we can solve for x to find both angles.

Solve for x.

(4x + 8) + (6x + 3) = 180

10x + 11 = 180

10x = 169

x = 16.9

Now, we know the value of x, so we plug in x for both angles to determine which angle is smaller.

4x + 8

4(16.9) + 8

67.6 + 8 = 75.6 degrees

and the other angle

6x + 3

6(16.9) + 3

101.4 + 3 = 104.4 degrees

Now we know that the smaller angle is 75.6 degrees.

Also, to make sure the math is correct, when plugging in both numbers after finding x, they should add to 180.

75.6 + 104.4 = 180 so we know they are supplementary for sure.

Good luck!

Write an equation for the following: y varies directly with x and z. Find K when x=2, y=12 and z=5.
