Find the range for the function: y=x-7 {-3,0,2,5}

trasher [3.6K]

Answer:

Range is : { -10, -7, -5, -2 }

Step-by-step explanation:

Given:

The function is given as:

$y=x-7$

The domain of the function = { -3, 0, 2, 5 }

A function's input is called its domain and a function's output is called its range.

The range depends on the domain values. So, the values of 'y' are the values of range and the values of 'x' are the values of domain.

Here, the domain is given as:

Domain = { -3, 0, 2, 5 }

We need to find the values of 'y' for each value of 'x' taken from the domain set.

Plug in $x=-3$ . This gives,

$y=-3-7=-10$

Plug in $x=0$ . This gives,

$y=0-7=-7$

Plug in $x=2$ . This gives,

$y=2-7=-5$

Plug in $x=-5$ . This gives,

$y=5-7=-2$

Therefore, the set of all values of 'y' is the range.

Range is equal to { -10, -7, -5, -2 }.

A math teacher instructed students to graph the following equations on a coordinate plane. y=2.5x+2 and y=2x+4. If graphed corre

algol [13]

Both the graphical lines will intersect at (4,12)

Step-by-step explanation:

Step 1; We must find the point in the graph where the lines of y=2.5x+2 and y=2x+4 intersect. To find out the intersecting point we must substitute values of x in both equations and see in which co-ordinate they are the same.

Step 2; We plot various values of x on the line governed by the equation y=2.5x+2

For a value of x=1 , y=2.5(1) + 2 = 4.5

For a value of x=2 , y=2.5(2) + 2 = 7

For a value of x= 3, y=2.5(3) + 2 = 9.5

For a value of x= 4, y=2.5(4) + 2 = 12

For a value of x= 5, y=2.5(5) + 2 = 14.5

Step 3; Now we also plot the values of x on the other line governed by y=2x+4

For a value of x= 1, y=2(1) + 4 = 6

For a value of x= 2, y=2(2) + 4 = 8

For a value of x= 3, y=2(3) + 4 = 10

For a value of x= 4, y=2(4) + 4 = 12

For a value of x= 5, y=2(5) + 4 = 14

Step 4; For both lines we must see if any of the values repeat at a particular point. In this case at the point (4,12) repeats for both so that becomes the point of intersection.

Solve for x when, 8x-12=4x

barxatty [35]

Answer:

x=3

Step-by-step explanation:

8x - 12 = 4x add 12 to both sides you get 8x=4x+12 subtract 4x on both sides then you get 4x=12 divide 4x on both sides and x = 3 Hope helps!!

8x-12=4x

+12 +12

__________

8x=4x+12

-4x -4x

_______-

4x=12

÷4 ÷4

______

x=3

Hope helps :3

A = bh/2 solve for b

rjkz [21]

$A = \dfrac{bh}{2}$

Cross multiply:
$2A = bh$

Divide by h on both sides:
$b = \dfrac{2A}{h}$
