Step-by-step explanation:

Let's solve for x.

y=4x+21

Step 1: Flip the equation.

4x+21=y

Step 2: Add -21 to both sides.

4x+21+−21=y+−21

4x=y−21

Answer:

x = 4

y = -3

Step-by-step explanation:

2x + 4y = -4

x + 2y = -2 ---------(1)

3x + 5y = -3 ----------(2)

Equation (1) multiplied by 3 then subtracted from equation (2),

(3x + 5y) - 3(x + 2y) = -3 + 6

-y = 3

y = -3

From equation (1)

x + 2(-3) = -2

x - 6 = -2

x = 6 - 2

x = 4

what is the range of the graph?

Answers

Answer:

The range is (-3,3)

Step-by-step explanation:

Range Of A Function from the Graph

The range of a function is the set of all those values it can take when x takes every possible element from the domain.

When the graph is given, the range can be obtained by placing an imaginary horizontal line from values of y as small as possible to values of y as high as possible. If the imaginary line passes through the graph of the function, then that value of y belongs to the range.

When we apply this approach, the line crosses the graph from y=-3 to y=3. The endpoints are not included because they have open circles there. Thus, the range is (-3,3)
