Answer:

PS = 28 units.

Step-by-step explanation:

See the attached diagram.

This is a figure of rectangle with length (3y + 3) and width 4y.

Now, the perimeter of the rectangle is 2[(3y + 3) + 4y] = 2(7y + 3)

The perimeter of the rectangle is given to be 104 units.

So, 2(7y + 3) = 104

⇒ 7y + 3 = 52

⇒ 7y = 49

⇒ y = 7

Therefore, PS = 4y = 4(7) = 28 units. (Answer)

Which points lie on the line whose equation is 8x - 2y + 7 = -9? Select all that apply.
Anestetic [448]

Answer:

A.(-2, 0)

C. (-1.4)

Step-by-step explanation:

we know that

If a point lie on the line, then the point must satisfy the equation of the line (makes the equation true)

we have

8x-2y+7=-9

subtract 7 both sides

8x-2y=-9-7

8x-2y=-16

divide by 2 both sides

4x-y=-8

Substitute the value of x and the value of y of each point in the linear equation and analyze the result

<u><em>Verify each point</em></u>

case A) we have

(-2, 0)

For x=-2, y=0

substitute

4(-2)-(0)=-8

-8=-8 ---> is true

so

the point lie on the line

case B) we have

(1, 3)

For x=1, y=3

substitute

4(1)-(3)=-8

1=-8 ---> is not true

so

the point not lie on the line

case C) we have

(-1, 4)

For x=-1, y=4

substitute

4(-1)-(4)=-8

-8=-8 ---> is true

so

the point lie on the line

case D) we have

(1, -4)

For x=1, y=-4

substitute

4(1)-(-4)=-8

8=-8 ---> is not true

so

the point not lie on the line

case E) we have

(0, -1)

For x=0, y=-1

substitute

4(0)-(-1)=-8

1=-8 ---> is not true

so

the point not lie on the line

Bad White [126]
Answer is z=36
First find the ratio of the similar sides
55/44 = 1.25 ratio
Divide 45 by the ratio to find z
45/1.25 = 36

If someone would help me with this problem I would greatly appreciate it I'll give you the brainliesrt if you get the answer rig
Tamiku [17]

Answer:

The function f is graphed.

f is an even function as it has U- form.

As per the graph there is one local maximum at (0, 4) and one local minimum at (6, 1).

The global minimum is (-9, -2) and the global maximum is infinity.

The minimum and maximums are the borders of the increasing or decreasing intervals.

<u>Intervals when the function is increasing: </u>

  • (-9, 0] and [6, +∞)

<u>Intervals when the function is decreasing: </u>

  • (-∞, -9] and [0, 6]
